  • Cannot complete a JSONP call from jQuery to WCF

    - by Dusda
    Okay, I am trying (poorly) to successfully make a JSONP call from jQuery on a test page to a WCF web service running locally, as a cross-domain call. I have, at one point or another, either gotten a 1012 URI denied error, gotten a response but in Xml, or just had no response at all. Currently, the way I have it configured it spits back a 1012. I did not write this web service, so it is entirely possible that I am just missing a configuration setting somewhere, but I've become so frustrated with it that I think just asking on here will be more productive. Thanks guys. Details below. I have a WCF web service with the following method: [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public decimal GetOrderStatusJson(int jobId) I am trying to call this method from a jQuery test page, via a cross-domain JSONP call. <script type="text/javascript"> getJsonAjaxObject( "http://localhost:3960/ProcessRequests.svc/json/GetOrderStatusJson", { "jobId": 232 }); function getJsonAjaxObject(webServiceUrl, jsonData) { var request = { type: "POST", contentType: "application/json; charset=utf-8", url: webServiceUrl, data: jsonData, dataType: "jsonp", success: function(msg) { //success! alert("blah"); }, error: function() { //oh nos alert("bad blah"); } }; $.ajax(request); } </script> Below are the chunks of the web.config I configure for this purpose: <services> <service behaviorConfiguration="MWProcessRequestWCF.ProcessRequestsBehavior" name="MWProcessRequestWCF.ProcessRequests"> <endpoint address="json" behaviorConfiguration="AspNetAjaxBehavior" binding="webHttpBinding" contract="MWProcessRequestWCF.IProcessRequests" /> <endpoint address="" binding="wsHttpBinding" contract="MWProcessRequestWCF.IProcessRequests"> <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="MWProcessRequestWCF.ProcessRequestsBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="AspNetAjaxBehavior"> <enableWebScript/> </behavior> </endpointBehaviors> </behaviors>

  • A Python Wrapper for Shutterfly. Uploading an Image

    - by iJames
    I'm working on a Django app in which I want to order prints through Shutterfly's Open API: http://www.shutterfly.com/documentation/start.sfly So far I've been able to build the appropriate POSTs and GETs using the modules and suggested code snippets including httplib, httplib2, urllib, urllib2, mimetype, etc. But I'm stuck on the image uploading when placing an order (the ordering process is not the same process as uploading images to albums which I haven't tried.) From what I can tell, I'm supposed to basically create the multipart form data by concatenating the HTTP request body together with the binary data of the image. I take the strings: --myuniqueboundary1273149960.175.1 Content-Disposition: form-data; name="AuthenticationID" auniqueauthenticationid --myuniqueboundary1273149960.175.1 Content-Disposition: file; name="Image.Data"; filename="1_41_orig.jpg" Content-Type: image/jpeg and I put this data into it and end with the final boundary: ...\xb5|\xf88\x1dj\t@\xd9\'\x1f\xc6j\x88{\x8a\xc0\x18\x8eGaJG\x03\xe9J-\xd8\x96[\x91T\xc3\x0eTu\xf4\xaa\xa5Ty\x80\x01\x8c\x9f\xe9Z\xad\x8cg\xba# g\x18\xe2\xaa:\x829\x02\xb4["\x17Q\xe7\x801\xea?\xad7j\xfd\xa2\xdf\x81\xd2\x84D\xb6)\xa8\xcb\xc8O\\\x9a\xaf(\x1cqM\x98\x8d*\xb8\'h\xc8+\x8e:u\xaa\xf3*\x9b\x95\x05F8\xedN%\xcb\xe1B2\xa9~Tw\xedF\xc4\xfe\xe8\xfc\xa9\x983\xff\xd9... That ends up making it look like this (when I use print to debug): ... --myuniqueboundary1273149960.175.1 Content-Disposition: file; name="Image.Data"; filename="1_41_orig.jpg" Content-Type: image/jpeg ????q?ExifMM* ? ??(1?2?<??i?b?NIKON CORPORATIONNIKON D40HHQuickTime 7.62009:02:17 13:05:25Mac OS X 10.5.6%??????"?'??0220?????? ???? ? ?|_???,b???50??5 ... --myuniqueboundary1273149960.175.1-- My code for grabbing the binary data is pretty much this: filedata = open('myjpegfile.jpeg','rb').read() Which I then add to the rest of the body. I've see something like this code everywhere. I'm then using this to post the full request (with the headers too): response = urllib2.urlopen(request).read() This seems to me to be the standard way that form POSTS with files happens. Am I missing something here? At some point I might be able to make this into a library worth posting up on github, but this problem has stopped me cold in my tracks. Thanks for any insight!

  • Programming Constructs History

    - by kunjaan
    I need some help in figuring out which language introduced the constructs that we use everyday. For example: Constructs Introduced from LISP If-Else Block :"The ubiquitous if-then-else structure, now taken for granted as an essential element of any programming language, was invented by McCarthy for use in Lisp, where it saw its first appearance in a more general form (the cond structure). It was inherited by Algol, which popularized it. " - WikiPedia Function Type : Functions as first class citizens. Garbage Collection

  • Apple Push Notifications With Foreign Accent Characters Not Receiving

    - by confeng
    I'm sending push notifications and when the message contains foreign characters (Turkish in my case) like I, s, ç, g... The message does not arrive to devices. Here's my code: $message = 'THIS is push'; $passphrase = 'mypass'; $ctx = stream_context_create(); stream_context_set_option($ctx, 'ssl', 'local_cert', 'MyPemFile.pem'); stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase); // Open a connection to the APNS server $fp = stream_socket_client( 'ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx); if (!$fp) exit("Failed to connect: $err $errstr" . PHP_EOL); echo 'Connected to Apple service. ' . PHP_EOL; // Encode the payload as JSON $body['aps'] = array( 'alert' => $message, 'sound' => 'default' ); $payload = json_encode($body); $result = 'Start'.PHP_EOL; $tokenArray = array('mytoken'); foreach ($tokenArray as $item) { // Build the binary notification $msg = chr(0) . pack('n', 32) . pack('H*', $item) . pack('n', strlen($payload)) . $payload; // Send it to the server $result = fwrite($fp, $msg, strlen($msg)); if (!$result) echo 'Failed message'.PHP_EOL; else echo 'Successful message'.PHP_EOL; } // Close the connection to the server fclose($fp); I have tried encoding $message variable with utf8_encode() but the message received as "THÝS is push". And other ways like iconv() didn't work for me, some of them cropped Turkish characters, some didn't receive at all. I also have header('content-type: text/html; charset: utf-8'); and <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> in my page. I don't think the problem appears while I set the value but maybe with pack() function. Any ideas to solve this without replacing characters with English?

  • How to stop emacs from replacing underbar with <- in ess-mode

    - by SetJmp
    ess-mode is "Emacs speaks statistics." This mode is useful for editing programs for R or Splus (two separate statistics packages). In my buffer, when ever I type '_' the character is replaced with "<-" which is very frustrating. Is there a emacs lisp statement to turn off this behavior? Thanks, SetJmp emacs: 22.1.1 ess-mode release (unknown)

  • Is it possible to pop open the upload file dialog without requiring the user to press Browse?

    - by superjoe30
    I think I've seen Gmail do it in Chrome or Internet Explorer, but I've never seen it in Firefox. I thought I'd ask anyways. Is it possible to do a file upload without requiring an <input type="file" />? I see that you can use iframes to automatically submit the file input, so my question is Can you programmatically pop up a file upload dialog? If so, what browsers is it supported on?

  • Should We Mask Passwords?

    - by Abi Noda
    From Jacob Nielson's "Stop Password Masking": Usability suffers when users type in passwords and the only feedback they get is a row of bullets. Typically, masking passwords doesn't even increase security, but it does cost you business due to login failures. What do you guys think?

  • ASP.Net JSON Web Service Post Form Data

    - by Will D
    I have a ASP.NET web service decorated with System.Web.Script.Services.ScriptService() so it can return json formatted data. This much is working for me, but ASP.Net has a requirement that parameters to the web service must be in json in order to get json out. I'm using jquery to run my ajax calls and there doesn't seem to be an easy way to create a nice javascript object from the form elements. I have looked at serialiseArray in the json2 library but it doesn't encode the field names as property name in the object. If you have 2 form elements like this <input type="text" name="namefirst" id="namefirst" value="John"/> <input type="text" name="namelast" id="namelast" value="Doe"/> calling $("form").serialize() will get you the standard query string namefirst=John&namelast=Doe calling JSON.stringify($("form").serializeArray()) will get you the (bulky) json representation [{"name":"namefirst","value":"John"},{"name":"namelast","value":"Doe"}] This will work when passing to the web service but its ugly as you have to have code like this to read it in: Public Class NameValuePair Public name As String Public value As String End Class <WebMethod()> _ Public Function GetQuote(ByVal nvp As NameValuePair()) As String End Function You would also have to wrap that json text inside another object nameed nvp to make the web service happy. Then its more work as all you have is an array of NameValuePair when you want an associative array. I might be kidding myself but i imagined something more elegant when i started this project - more like this Public Class Person Public namefirst As String Public namelast As String End Class which would require the json to look something like this: {"namefirst":"John","namelast":"Doe"} Is there an easy way to do this? Obviously it is simple for a form with two parameters but when you have a very large form concatenating strings gets ugly. Having nested objects would also complicate things The cludge I have settled on for the moment is to use the standard name value pair format stuffed inside a json object. This is compact and fast {"q":"namefirst=John&namelast=Doe"} then have a web method like this on the server that parses the query string into an associate array. <WebMethod()> _ Public Function AjaxForm(ByVal q As String) as string Dim params As NameValueCollection = HttpUtility.ParseQueryString(q) 'do stuff return "Hello" End Sub As far a cludges go this one seems reasonably elegant in terms of amount of code, but my question is: is there a better way? Is there a generally accepted way of passing form data to asp.net web/script services?

  • How do I use unsafe values in an enum?

    - by Jon Tackabury
    I need to use this enum in my C# application, but it won't let me use these values. When I specify the type as uint I can use the -1 value, and when I specify int I can't use the last 2 values. Is there a way to use the unchecked keyword here to allow me to define all of these values? These values are coming from an external source, so I can't change them. internal enum MyValues : int { value1 = -1, value2 = 0, value3 = 0x80000000, value4 = 0xFFFFFFFF }

  • In XMLHttpRequest, where is error flag variable?

    - by Tiangolo
    In the XMLHttpRequest Spec it says that: The DONE state has an associated error flag that indicates some type of network error or abortion. It can be either true or false and has an initial value of false. Also says something similar about a "send() flag" in an "OPENED" state. It's said in the specification but not in the IDL and when I create a new XMLHttpRequest I can't find those "flags". Where are those boolean variables?

  • Can I make Axis2 generate a WSDL with 'unwrapped' types?

    - by Bedwyr Humphreys
    I'm trying to consume a hello world AXIS2 SOAP web service using a PHP client. The Java class is written in Netbeans and the AXIS2 aar file is generated using the Netbeans AXIS2 plugin. You've all seen it before but here's the java class: public class SOAPHello { public String sayHello(String username) { return "Hello, "+username; } } The wsdl genereated by AXIS2 seems to wrap all the parameters so that when I consume the service i have to use a crazy PHP script like this: $client = new SoapClient("http://myhost:8080/axis2/services/SOAPHello?wsdl"); $parameters["username"] = "Dave"; $response = $client->sayHello($parameters)->return; echo $response."!"; When all I really want to do is echo $client->sayHello("Dave")."!"; My question is two-fold: why is this happening? and what can I do to stop it? :) Here's are the types, message and porttype sections of the generated wsdl: <wsdl:types> <xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://soap.axis2.myhost.co.uk"> <xs:element name="sayHello"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="username" nillable="true" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="sayHelloResponse"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="return" nillable="true" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> </wsdl:types> <wsdl:message name="sayHelloRequest"> <wsdl:part name="parameters" element="ns:sayHello"/> </wsdl:message> <wsdl:message name="sayHelloResponse"> <wsdl:part name="parameters" element="ns:sayHelloResponse"/> </wsdl:message> <wsdl:portType name="SOAPHelloPortType"> <wsdl:operation name="sayHello"> <wsdl:input message="ns:sayHelloRequest" wsaw:Action="urn:sayHello"/> <wsdl:output message="ns:sayHelloResponse" wsaw:Action="urn:sayHelloResponse"/> </wsdl:operation> </wsdl:portType>

  • How to monitor a POP, SMTP and Exchange Server for mail activity

    We need to write a .Net (C#) application that monitors all mail activity through a POP, SMTP and Exchange Server (2007 and later) and essentially grab the mail for archiving into a document management system. I realise that the way to monitor each type of server would probably be different so I'd like to know what the best (most elegant and reliable) way is to achieve this. Thanks.

  • Using jQuery live() to initialize plugins?

    - by cxfx
    Using jQuery, what's the best way to automatically initialize a plugin on all current and future elements of a specific class? For example, say I want all <input type="text" class="datepicker" /> elements to have the jQuery UI Datepicker plugin, including any I might create at runtime. Essentially, I want to do something like this: $('.datepicker').live('create', function() { $(this).datepicker(); }); But, of course, there isn't a create event I can use.
