  • Perl - WWW::Mechanize Cookie Session Id is being reset with every get(), how to make it stop?

    - by Phill Pafford
    So I'm scraping a site that I have access to via HTTPS, I can login and start the process but each time I hit a new page (URL) the cookie Session Id changes. How do I keep the logged in Cookie Session Id? #!/usr/bin/perl -w use strict; use warnings; use WWW::Mechanize; use HTTP::Cookies; use LWP::Debug qw(+); use HTTP::Request; use LWP::UserAgent; use HTTP::Request::Common; my $un = 'username'; my $pw = 'password'; my $url = 'https://subdomain.url.com/index.do'; my $agent = WWW::Mechanize->new(cookie_jar => {}, autocheck => 0); $agent->{onerror}=\&WWW::Mechanize::_warn; $agent->agent('Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.3) Gecko/20100407 Ubuntu/9.10 (karmic) Firefox/3.6.3'); $agent->get($url); $agent->form_name('form'); $agent->field(username => $un); $agent->field(password => $pw); $agent->click("Log In"); print "After Login Cookie: "; print $agent->cookie_jar->as_string(); print "\n\n"; my $searchURL='https://subdomain.url.com/search.do'; $agent->get($searchURL); print "After Search Cookie: "; print $agent->cookie_jar->as_string(); print "\n"; The output: After Login Cookie: Set-Cookie3: JSESSIONID=367C6D; path="/thepath"; domain=subdomina.url.com; path_spec; secure; discard; version=0 After Search Cookie: Set-Cookie3: JSESSIONID=855402; path="/thepath"; domain=subdomain.com.com; path_spec; secure; discard; version=0 Also I think the site requires a CERT (Well in the browser it does), would this be the correct way to add it? $ENV{HTTPS_CERT_FILE} = 'SUBDOMAIN.URL.COM'; ## Insert this after the use HTTP::Request... Also for the CERT In using the first option in this list, is this correct?

  • Progress Bar design patterns?

    - by shoosh
    The application I'm writing performs a length algorithm which usually takes a few minutes to finish. During this time I'd like to show the user a progress bar which indicates how much of the algorithm is done as precisely as possible. The algorithm is divided into several steps, each with its own typical timing. For instance- initialization (500 milli-sec) reading inputs (5 sec) step 1 (30 sec) step 2 (3 minutes) writing outputs (7 sec) shutting down (10 milli-sec) Each step can report its progress quite easily by setting the range its working on, say [0 to 150] and then reporting the value it completed in its main loop. What I currently have set up is a scheme of nested progress monitors which form a sort of implicit tree of progress reporting. All progress monitors inherit from an interface IProgressMonitor: class IProgressMonitor { public: void setRange(int from, int to) = 0; void setValue(int v) = 0; }; The root of the tree is the ProgressMonitor which is connected to the actual GUI interface: class GUIBarProgressMonitor : public IProgressMonitor { GUIBarProgressMonitor(ProgressBarWidget *); }; Any other node in the tree are monitors which take control of a piece of the parent progress: class SubProgressMonitor : public IProgressMonitor { SubProgressMonitor(IProgressMonitor *parent, int parentFrom, int parentLength) ... }; A SubProgressMonitor takes control of the range [parentFrom, parentFrom+parentLength] of its parent. With this scheme I am able to statically divide the top level progress according to the expected relative portion of each step in the global timing. Each step can then be further subdivided into pieces etc' The main disadvantage of this is that the division is static and it gets painful to make changes according to variables which are discovered at run time. So the question: are there any known design patterns for progress monitoring which solve this issue?

  • Problem with asp.net function syntax (not returning values correctly)

    - by Phil
    I have an active directory search function: Function GetAdInfo(ByVal ADDN As String, ByVal ADCommonName As String, ByVal ADGivenName As String, ByVal ADStaffNum As String, ByVal ADEmail As String, ByVal ADDescription As String, ByVal ADTelephone As String, ByVal ADOffice As String, ByVal ADEmployeeID As String) As String Dim netBIOSname As String = Me.Request.LogonUserIdentity.Name Dim sAMAccountName As String = netBIOSname.Substring(netBIOSname.LastIndexOf("\"c) + 1) Dim defaultNamingContext As String Using rootDSE As DirectoryServices.DirectoryEntry = New DirectoryServices.DirectoryEntry("LDAP://RootDSE") defaultNamingContext = rootDSE.Properties("defaultNamingContext").Value.ToString() End Using Using searchRoot As DirectoryServices.DirectoryEntry = _ New DirectoryServices.DirectoryEntry("LDAP://" + defaultNamingContext, _ "kingkong", "kingkong", DirectoryServices.AuthenticationTypes.Secure) Using ds As DirectoryServices.DirectorySearcher = New DirectoryServices.DirectorySearcher(searchRoot) ds.Filter = String.Format("(&(objectClass=user)(objectCategory=person)(sAMAccountName={0}))", sAMAccountName) Dim sr As DirectoryServices.SearchResult = ds.FindOne() 'If sr.Properties("displayName").Count = 0 Then whatever = string.empty '' (how to check nulls when required) ' End If ADDN = (sr.Properties("displayName")(0).ToString()) ADCommonName = (sr.Properties("cn")(0).ToString()) ADGivenName = (sr.Properties("givenname")(0).ToString()) ADStaffNum = (sr.Properties("sn")(0).ToString()) ADEmail = (sr.Properties("mail")(0).ToString()) ADDescription = (sr.Properties("description")(0).ToString()) ADTelephone = (sr.Properties("telephonenumber")(0).ToString()) ADOffice = (sr.Properties("physicalDeliveryOfficeName")(0).ToString()) ' ADEmployeeID = (sr.Properties("employeeID")(0).ToString()) End Using End Using Return ADDN Return ADCommonName Return ADGivenName Return ADStaffNum Return ADEmail Return ADDescription Return ADTelephone Return ADOffice ' Return ADEmployeeID 'have commented out employee id as i dont have one so it is throwing null errors.

Then I call the function in my page_load like this: GetAdInfo(ADDN, ADCommonName, ADGivenName, ADStaffnum, ADEmail, ADDescription, ADTelephone, ADOffice, ADEmployeeID) Then I try to response.write out one of the vars to test like this: Response.Write(ADDN) But the value is empty. Please can someone tell me what I am doing wrong. Thanks

  • Android Dev Help: Saving an image from Res/raw or Asset folder to the Sd card

    - by Lucy
    Android Development Query Hello, I wonder if anyone could help me, i am trying to save an image (jpg or png) from the res/raw or assets folder to the SD card location (/sdcard/DCIM/). I have been following a tutorial which can save an image from a URL to the SD card Root, but i have looked everywhere to be able to save from res/raw or asset folder instead, and to a differnet location onthe sd card /sdcard/DCIM/ Here is the code, can anyone show me how to do the above from this? Thanks Lucy public class home extends Activity { private File file; private String imgNumber; private Button btnDownload; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); btnDownload=(Button)findViewById(R.id.btnDownload); btnDownload.setOnClickListener(new OnClickListener() { public void onClick(View v) { btnDownload.setText("Download is in Progress."); String savedFilePath=Download("http://www.domain.com/android1.png"); Toast.makeText(getApplicationContext(), "File is Saved in "+savedFilePath, 1000).show(); if(savedFilePath!=null) { btnDownload.setText("Download Completed."); } } }); } public String Download(String Url) { String filepath=null; try { //set the download URL, a url that points to a file on the internet //this is the file to be downloaded URL url = new URL(Url); //create the new connection HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); //set up some things on the connection urlConnection.setRequestMethod("GET"); urlConnection.setDoOutput(true); //and connect! urlConnection.connect(); //set the path where we want to save the file //in this case, going to save it on the root directory of the //sd card.

  • Image Conversion from Bitmap to Icon doesn't seem to work

    - by contactmatt
    I have a simple function that takes a bitmap, and converts the bitmap to an ICON format. Below is the function. (I placed literal values in place of the variables) Bitmap tempBmp = new Bitmap(@"C:\temp\mypicture.jpeg"); Bitmap bmp = new Bitmap(tempBmp, 16, 16); bmp.Save("@C:\temp\mypicture2.ico", ImageFormat.Icon) It doesn't seem to be converting correctly...or so I think. After the image is converted, some browsers do not reconigze the image as a true "ICON" , and even Visual Studio 2008 doesn't reconigze the image as an icon after its converted to an Icon format. For example, I was going to set the Icon property for my Win32 form app with the Icon i just converted. I open the dialouge box and select the icon I just converted and get the following error. -- "Argument 'picture' must be a picture that can be used as a Icon." I've browsed the web and come across complicated code where people take the time to manually convert the bitmap to different formats, but I would think the above code should work, and that the .NET framework would take care of this conversion.

  • Need help with buffer overrun.

    - by Morinar
    I've got a buffer overrun I absolutely can't see to figure out (in C). First of all, it only happens maybe 10% of the time or so. The data that it is pulling from the DB each time doesn't seem to be all that much different between executions... at least not different enough for me to find any discernible pattern as to when it happens. The exact message from Visual Studio is this: A buffer overrun has occurred in hub.exe which has corrupted the program's internal state. Press Break to debug the program or Continue to terminate the program. For more details please see Help topic 'How to debug Buffer Overrun Issues'. If I debug, I find that it is broken in __report_gsfailure() which I'm pretty sure is from the /GS flag on the compiler and also signifies that this is an overrun on the stack rather than the heap. I can also see the function it threw this on as it was leaving, but I can't see anything in there that would cause this behavior, the function has also existed for a long time (10+ years, albeit with some minor modifications) and as far as I know, this has never happened. I'd post the code of the function, but it's decently long and references a lot of proprietary functions/variables/etc. I'm basically just looking for either some idea of what I should be looking for that I haven't or perhaps some tools that may help. Unfortunately, nearly every tool I've found only helps with debugging overruns on the heap, and unless I'm mistaken, this is on the stack. Thanks in advance.

  • Advice moving from Eclipse to xCode

    - by Gloin the Dark
    To xCode xPerts: I have been doing Java in Eclipse for about 9 years now and I have really gotten used to the power of the refactoring tools. There are a few operations I do all the time. I am looking for equivalents in xCode since it has better support for objective-c than eclipse. (I'm not at my Mac as I write this. So some of this is from memory. I am still very new to xCode.) 1 "rename". It seems that the xCode equivalent for variables is "edit all in scope". Does this work for files/classes/methods too? 2 "extract local variable" select an expression it creates a local var initialized to that expression. It even creates a usable name for the variable. 3 "extract method" select some code and it will create a method with that code and appropriate parameters/return value. 4 "inline" (variable or method) opposite of extract, inlines all or just the selected occurrence of the selected var or method. 5 "find next" occurrence of selected text. In eclipse I can select some text and hit ctrl-k to go to the next occurrence of that in the file. likewise shift-ctrl-k finds backwards. IIRC the xCode "find next" ignores the selection and only uses what is in the find box. 6 "change method signature" This would be very useful with ocjective-c's named parameter messaging syntax. This is great for adding parameters to a method. 7 "pull-up/push-down" for moving methods up or down the class hierarchy. 8 "move" for moving elements around to other classes etc. Those are the ones that I use all of the time. I have estimated that these tools cut my coding time in half. Are any of these supported in xCode? Thanks in advance for any advice.

  • cryptic error message: Length of Bind host variable exceeds MaxLength

    - by janetsmith
    Hi, I've encountered a cryptic error message thrown by Sybase IQ server. com.sybase.jdbc2.jdbc.SybSQLException: ASA Error -1001019: Function not supported on varchars longer than 255 Length of Bind host variable exceeds MaxLength , -- (df_Heap.cxx 2145) at com.sybase.jdbc2.tds.Tds.processEed(Tds.java:2636) at com.sybase.jdbc2.tds.Tds.nextResult(Tds.java:1996) at com.sybase.jdbc2.jdbc.ResultGetter.nextResult(ResultGetter.java:69) at com.sybase.jdbc2.jdbc.SybStatement.nextResult(SybStatement.java:204) at com.sybase.jdbc2.jdbc.SybStatement.nextResult(SybStatement.java:187) at com.sybase.jdbc2.jdbc.SybStatement.updateLoop(SybStatement.java:1642) at com.sybase.jdbc2.jdbc.SybStatement.executeUpdate(SybStatement.java:1625) at com.sybase.jdbc2.jdbc.SybPreparedStatement.executeUpdate(SybPreparedStatement.java:91) at ibs.dao.CM3RM1DAO.updateToTable(CM3RM1DAO.java:197) at ibs.dao.CM3RM1DAO.isXMLProcessed(CM3RM1DAO.java:88) at ibs.xml.parser.XMLParser.parsingXMLIntoBO(XMLParser.java:2125) at ibs.common.util.MainClass.main(MainClass.java:74) We have several columns (DESCRIPTION etc.) which are of type varchar(4000).

  • Webservice complex types and class inheritance

    - by pygorex1
    Using the following Webservice definition using aClientArgs as a complex type: [System.Web.Script.Services.ScriptService] public class Controller : System.Web.Services.WebService { [WebMethod] public void save_client(aClientArgs client) { // Save client data } } Then defining aClientArgs as a sub-class: public class aArgs { public string id = null; public string name = null; } public class aClientArgs : aArgs { public string address = null; public string website = null; } Returns the following WSDL fragment for the save_client args: <save_client xmlns="http://tempuri.org/"> <client> <address>string</address> <website>string</website> </client> </save_client> When I'm expecting the following: <save_client xmlns="http://tempuri.org/"> <client> <id>string</id> <name>string</name> <address>string</address> <website>string</website> </client> </save_client> So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

  • ASP.NET page content doesn't change

    - by WtFudgE
    Hi, I created an application which has a menu where it's items are created dynamicly. The menu acts as a language menu. <body runat="server"> <form id="Form1" runat="server"> <table class="TableLayout"> <tr> <td class="TopNav" align="right"> <asp:Menu runat="server" ID="LanguageMenu" Orientation="Horizontal" OnMenuItemClick="LanguageMenu_MenuItemClick"> <LevelMenuItemStyles> <asp:MenuItemStyle CssClass="TopNavItem" /> </LevelMenuItemStyles> <StaticHoverStyle CssClass="TopNavItemHover" /> </asp:Menu> </td> </tr> ... I use session variables to set my current language. however if I click on the menu to change the session variable: public void LanguageMenu_MenuItemClick(Object sender, MenuEventArgs e) { Session["language"] = e.Item.Text; } The page reloads with the following code: sportsPath = String.Format(@"{0}{1}\Sports\", xmlPath, Session["language"]); //create LeftNavigation string[] sports = Directory.GetFiles(sportsPath); LeftNavigation.Items.Clear(); foreach (string sport in sports) { string text = sport.Replace(sportsPath, "").Replace(".xml", ""); MenuItem item = new MenuItem(); item.Text = text; LeftNavigation.Items.Add(item); } The thing is the content doesn't change, only after I click on something else. If I skip through my code after clicking on the menuItem I can see that it passes the code and it should change, however for some reason the page needs another extra trigger to modify it's content. I also see the page reloading so I don't understand why it's not changing immediatly. I guess I'm not understanding the asp.net logic just quite yet. What am I doing wrong?

  • Missing ideas in programming language design

    - by meyka
    I wanted to try something new and so I designed some programming languages and wrote interpreters for them: A rather low-level, not very expressive language. (I didn't want to parse complex expressions right at the beginning) It featured: Variables (yay) Subroutines, with a call stack Basic arithmetic functions, basic string manipulation, ... Code in the language looks like this: set i 0 inc i print i Very, very basic you see. A more high-level language I decided to make it structured and so it featured things like if-else, while, functions, and so on. The stuff most programming languages have. Ended up like a unworthy Python clone, I hated that. A code-golf language Which ended up similar to J, golfcode, APL, etc. Nothing special As you can see: I don't lack the skills but the ideas. I can't figure out anything new, not even bad, unneccessary things, for my languages. - Do you know of some weird things I could implement in my languages, which don't try to make programming harder (like most esoteric languages) but funnier or more different from other languages? It can't be possible that every weird thing has been tried out so far, or?

  • New at Python: GLPK not building properly / Python ImportError

    - by Merjit
    This is a beginner question, and a follow-up to this one, where I was pointed to GLPK. I'm trying to get PyGLPK, a Python binding for the GNU Linear Programming Kit up and running, but no matter what I do, I can't seem to build and install GLPK so that Python finds it correctly. This comes after running ./configure, make, and sudo make install on the GLPK libraries, and following the instructions for PyGLPK. Specifically, here is the error I get: >>> import glpk Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site- packages/glpk.so, 2): Symbol not found: __glp_lpx_print_ips Referenced from: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/glpk.so Expected in: dynamic lookup I assume that something isn't linking to somewhere else, and that it probably has something to do with paths and environment variables. However, here's where my abilities in the shell fail, and I'm at a loss over what to do next. Again, there is probably a simple answer to this, but I haven't had any luck with Google using the terminology I know.

  • How to forward a 'saved' request stream to another Action within the same controller?

    - by Moe Howard
    We have a need to chunk-up large http requests sent by our mobile devices. These smaller chunk streams are merged to a file on the server. Once all chunks are received we need a way to submit the saved merged request to an another method(Action) within the same controller that will process this large http request. How can this be done? The code we tried below results in the service hanging. Is there a way to do this without a round-trip? //Open merged chunked file FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read); //Read steam support variables int bytesRead = 0; byte[] buffer = new byte[1024]; //Build New Web Request. The target Action is called "Upload", this method we are in is called "UploadChunk" HttpWebRequest webRequest; webRequest = (HttpWebRequest)WebRequest.Create(Request.Url.ToString().Replace("Chunk", string.Empty)); webRequest.Method = "POST"; webRequest.ContentType = "text/xml"; webRequest.KeepAlive = true; webRequest.Timeout = 600000; webRequest.ReadWriteTimeout = 600000; webRequest.Credentials = System.Net.CredentialCache.DefaultCredentials; Stream webStream = webRequest.GetRequestStream(); //Hangs here, no errors, just hangs I have looked into using RedirectToAction and RedirecctToRoute but these methods don't fit well with what we are looking to do as we cannot edit the Request.InputStream (as it is read-only) to carry out large request stream.

  • Maven antrun with sequential ant-contrib fails to run

    - by codevour
    We have a special routine to explode files in a subfolder into extensions, which will be copied and jared into single extension files.

  • What makes static initialization functions good, bad, or otherwise?

    - by Richard Levasseur
    Suppose you had code like this: _READERS = None _WRITERS = None def Init(num_readers, reader_params, num_writers, writer_params, ...args...): ...logic... _READERS = new ReaderPool(num_readers, reader_params) _WRITERS = new WriterPool(num_writers, writer_params) ...more logic... class Doer: def __init__(...args...): ... def Read(self, ...args...): c = _READERS.get() try: ...work with conn finally: _READERS.put(c) def Writer(...): ...similar to Read()... To me, this is a bad pattern to follow, some cons: Doers can be created without its preconditions being satisfied The code isn't easily testable because ConnPool can't be directly mocked out. Init has to be called right the first time. If its changed so it can be called multiple times, extra logic has to be added to check if variables are already defined, and lots of NULL values have to be passed around to skip re-initializing. In the event of threads, the above becomes more complicated by adding locking Globals aren't being used to communicate state (which isn't strictly bad, but a code smell) On the other hand, some pros: its very convenient to call Init(5, "user/pass", 2, "user/pass") It simple and "clean" Personally, I think the cons outweigh the pros, that is, testability and assured preconditions outweigh simplicity and convenience.

  • How to prevent latex memory overflow

    - by drasto
    I've got a latex macro that makes small pictures. In that picture I need to draw area. Borders of that area are quadratic bezier curves and that area is to be filled. I did not know how to do it so currently I'm "filling" the area by drawing a plenty of bezier curves inside it... This slows down typeseting and when a macro is used multiple times (so tex is drawing really a lot of quadratic bezier curves) it produces following error: ! TeX capacity exceeded, sorry [main memory size=3000000]. How can I prevent this error ? (by freeing memory after macro or such...) Or even better how do I fill the area determined by two quadratic bezier curves? Code that produces error: \usepackage{forloop} \usepackage{picture} \usepackage{eepic} ... \linethickness{\lineThickness\unitlength}% \forloop[\lineThickness]{cy}{\cymin}{\value{cy} < \cymax}{% \qbezier(\ax, \ay)(\cx, \value{cy})(\bx, \by)% }% Here are some example values for variables: \setlength{\unitlength}{0.01pt} \lineThickness=20 %cy is just a counter - inital value is not important \cymin=450 \cymax=900 %from following only the difference between \ax and \bx is important \ax=0 \ay=0 \bx=550 \by=0 Note: To reproduce the error this code have to execute approximately 150 times (could be more depending on your latex memory settings). Thanks a lot for any help

  • jquery use return data from 2 functions in another function ---always get undefined. why ??

    - by user253530
    Function socialbookmarksTableData(data) is called by another function to generate the content of a table -- data is a JSON object. Inside the function i call 2 other functions that use getJSON and POST (with json as a return object) to get some data. The problem is: though the functions execute correctly i get undefined value for the 2 variables (bookmarkingSites, bookmarkCategories). Help with a solution please. function socialbookmarksGetBookmarkCategories(bookmarkID) { var toReturn = ''; $.post("php/socialbookmark-get-bookmark-categories.php",{ bookmarkID: bookmarkID },function(data){ $.each(data,function(i,categID){ toReturn += '<option value ="' + data[i].categID + '">' + data[i].categName + '</option>'; }) return toReturn; },"JSON"); } function socialbookmarksGetBookmarkSites() { var bookmarkingSites = ''; $.getJSON("php/socialbookmark-get-bookmarking-sites.php",function(bookmarks){ for(var i = 0; i < bookmarks.length; i++){ //alert( bookmarks[i].id); bookmarkingSites += '<option value = "' + bookmarks[i].id + '">' + bookmarks[i].title + '</option>'; } return bookmarkingSites; }); } function socialbookmarksTableData(data) { var toAppend = ''; var bookmarkingSites = socialbookmarksGetBookmarkSites(); $.each(data.results, function(i, id){ var bookmarkCategories = socialbookmarksGetBookmarkCategories(data.results[i].bookmarkID); //rest of the code is not important }); $("#searchTable tbody").append(toAppend); }

  • JSON Formatting with Jersey, Jackson, & json.org/java Parser using Curl Command

    - by socal_javaguy
    Using Java 6, Tomcat 7, Jersey 1.15, Jackson 2.0.6 (from FasterXml maven repo), & www.json.org parser, I am trying to pretty print the JSON String so it will look indented by the curl -X GET command line. I created a simple web service which has the following architecture: My POJOs (model classes): Family.java import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class Family { private String father; private String mother; private List<Children> children; // Getter & Setters } Children.java import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class Children { private String name; private String age; private String gender; // Getters & Setters } Using a Utility Class, I decided to hard code the POJOs as follows: public class FamilyUtil { public static Family getFamily() { Family family = new Family(); family.setFather("Joe"); family.setMother("Jennifer"); Children child = new Children(); child.setName("Jimmy"); child.setAge("12"); child.setGender("male"); List<Children> children = new ArrayList<Children>(); children.add(child); family.setChildren(children); return family; } } My web service: import java.io.IOException; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import javax.ws.rs.core.MediaType; import org.codehaus.jackson.JsonGenerationException; import org.codehaus.jackson.map.JsonMappingException; import org.codehaus.jackson.map.ObjectMapper; import org.codehaus.jettison.json.JSONException; import org.json.JSONObject; import org.json.JSONTokener; import com.myapp.controller.myappController; import com.myapp.resource.output.HostingSegmentOutput; import com.myapp.util.FamilyUtil; @Path("") public class MyWebService { @GET @Produces(MediaType.APPLICATION_JSON) public static String getFamily() throws IOException, JsonGenerationException, JsonMappingException, JSONException, org.json.JSONException { ObjectMapper mapper = new ObjectMapper(); String uglyJsonString = mapper.writeValueAsString(FamilyUtil.getFamily()); System.out.println(uglyJsonString); JSONTokener tokener = new JSONTokener(uglyJsonString); JSONObject finalResult = new JSONObject(tokener); return finalResult.toString(4); } } When I run this using: curl -X GET http://localhost:8080/mywebservice I get this in my Eclipse's console: {"father":"Joe","mother":"Jennifer","children":[{"name":"Jimmy","age":"12","gender":"male"}]} But from the curl command on the command line (this response is more important): "{\n \"mother\": \"Jennifer\",\n \"children\": [{\n \"age\": \"12\",\n \"name\": \"Jimmy\",\n \"gender\": \"male\"\n }],\n \"father\": \"Joe\"\n}" This is adding newline escape sequences and placing double quotes (but not indenting like it should it does have 4 spaces after the new line but its all in one line). Would appreciate it if someone could point me in the right direction.

  • Add a custom variable to an email header already within a gmail inbox

    - by Ali
    Hi guys - this may seem odd but I was wondering if it was possible to add custom header details to emails already in an inbox. Like lets say I wish to add in the Header of the email something like - myvariable = myvalue and then be able to query it somehow. I'm looking at code from Iloha mail and most of the details like subject and from recieved etc are in the headers and you can search through them. SO is it possible to add my own custom variable to an email header and query it in the same way? How can it be done using php? EDIT ==================== Thanks I know how you can modify the headers of sent messages plus also query for custom variables in message headers however in this case I want to know if it would be possible to add a custom variable in a recieved message already in my inbox. Actually let me define the situation here. I'm working on a google apps solution which requires maintaining references to emails. Basically the application is as such that when an email comes in - we create an order from that email and wish to maintain a reference to that EXACT email by some kind of identifier which would enable us to identify that email. The fact is that we don't want to download the emails in a database and maintain a separate store as we would want to keep all the emailing on GMAIL. We just need: A way to be able to 'link' to a specific email permanently - the UID is just a sequence number and not very reliable. We couldn't find any property of emails that could function as a unique ID or primary key and so we thought if we could instead generate a key on our end and store it in a custom variable on the email itself. However it seems unfortunately that there isn't a way to manipulate headers of an already existing email. :( is there any solution to this problem I could use any IDEA !

  • Sending hidden fields via POST in iPhone in-app email

    - by Michael
    I'm letting my App's user send email from within the app to share some content on myserver. To do so I need to include a button with two bits of data and I want to use POST to keep it somewhat hidden. I've decided to add an html form using POST and two hidden fields in the email rather, like so: NSString *buttonCode = [NSString stringWithFormat:@"<form method='post' action='http://www.example.com/iphone/nifty.php'> <input type='hidden' name='dataOne' value='%@'> <input type='hidden' name='dataTwo' value='%@'> <input type='submit'value='Submit'></form>",dataOne, dataTwo]; NSString *emailBody = [NSString stringWithFormat: @"<b>%@ - %@</b>\n\n<HR WIDTH=200 SIZE=2 COLOR=#755f0f ALIGN=CENTER>\n Here is a email:<br><br>%@", dateString, timeString, buttonCode]; [picker setMessageBody:emailBody isHTML:YES]; I've confirmed by looking at the raw source of the email that the form is constructed correctly and I've copied and pasted it into a web page and it works. So here is the problem. When I click on the button in the received email (using apple's mail client) the dataOne and dataTwo variables don't get passed to my server. Is there a better way to do this or is the issue with my mail client?
