  • Add Access-Control-Allow-Origin to header in PHP

    - by SANDeveloper
    I am trying to workaround CORS restriction on a WebGL application. I have a Web Service which resolves URL and returns images. Since this web service is not CORS enabled, I can't use the returned images as textures. I was planning to: Write a PHP script to handle image requests Image requests would be sent through the query string as a url parameter The PHP Script will: Call the web service with the query string url Fetch the image response (web service returns a content-type:image response) Add the CORS header (Add Access-Control-Allow-Origin) to the response Send the response to the browser I tried to implement this using a variety of techniques including CURL, HTTPResponse, plain var_dump etc. but got stuck at some point in each. So I have 2 questions: Is the approach good enough? Considering the approach is good enough: I made the most progress with CURL. I could get the image header and data with: $ch = curl_init(); $url = $_GET["url"]; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:image/jpeg')); //Execute request $response = curl_exec($ch); //get the default response headers $headers = curl_getinfo($ch); //close connection curl_close($ch); But this doesn't actually change set the response content-type to image/jpeg. It dumps the header + response into a new response of content-type text/html and display the header and the image BLOB data in the browser. How do I get it to send the response in the format I want? Managed to get it working: $ch = curl_init(); $url = $_GET["url"]; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, false); //Execute request $response = curl_exec($ch); //get the default response headers $headers = curl_getinfo($ch); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); header('Content-Type: image/jpeg'); header("Access-Control-Allow-Origin: *"); // header("Expires: Sat, 26 Jul 2017 05:00:00 GMT"); //close connection curl_close($ch); flush();

  • How to access a named element of a derived user control in silverlight ?

    - by Mrt
    Hello, I have a custom base user control in silverlight. <UserControl x:Class="Problemo.MyBaseControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <Border Name="HeaderControl" Background="Red" /> </Grid> </UserControl> With the following code behind public partial class MyBaseControl : UserControl { public UIElement Header { get; set; } public MyBaseControl() { InitializeComponent(); Loaded += MyBaseControl_Loaded; } void MyBaseControl_Loaded(object sender, RoutedEventArgs e) { HeaderControl.Child = Header; } } I have a derived control. <me:MyBaseControl x:Class="Problemo.MyControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:me="clr-namespace:Problemo" d:DesignHeight="300" d:DesignWidth="400"> <me:MyBaseControl.Header> <TextBlock Name="header" Text="{Binding Text}" /> </me:MyBaseControl.Header> </me:MyBaseControl> With the following code behind. public partial class MyControl : MyBaseControl { public string Text { get; set; } public MyControl(string text) { InitializeComponent(); Text = text; } } I'm trying to set the text value of the header textblock in the derived control. It would be nice to be able to set both ways, i.e. with databinding or in the derived control code behind, but neither work. With the data binding, it doesn't work. If I try in the code behind I get a null reference to 'header'. This is silverlight 4 (not sure if that makes a difference) Any suggestions on how to do with with both databinding and in code ? Cheers

    Hi, I'm trying to get the unix time for date strings that are formatted like so: 'second sunday of march 2010' 'first sunday of november 2010' I was under the impression that strtotime could handle such a string, but apparently not, as this returns false. How can I convert to unix time when given a day of week, which one of those in the month (ie. first, second, etc.), a month and a year.

  • "Access violation reading location" while accessing a global vector..

    - by djzmo
    Hello there, -- First of all, I don't know whether the vector can be called as a "global vector" if I declared it under a namespace, but not in a class or function. -- I'm now writing a simple Irrlicht (http://irrlicht.sourceforge.net) wrapper for my game to make things simpler and easier, but recently I got an "Access violation reading location" error when trying to push_back a vector declared in the global scope. Here is my code so far: irrwrap.cpp: namespace irrw { //......... IrrlichtDevice *device; IVideoDriver *driver; irr::core::array<irr::video::ITexture*> TextureCollector; vector<int> TextureConnector; //......... } //.............. void irrInit(int iGraphicsDriver, int iWindowWidth, int iWindowHeight, int iScreenDepth, bool bFullScreen) { E_DRIVER_TYPE drvT; if(iGraphicsDriver == GD_SOFTWARE) drvT = EDT_SOFTWARE; else if(iGraphicsDriver == GD_D3D8) drvT = EDT_DIRECT3D8; else if(iGraphicsDriver == GD_D3D9) drvT = EDT_DIRECT3D9; else if(iGraphicsDriver == GD_OPENGL) drvT = EDT_OPENGL; //.............. irrw::device = createDevice(drvT, dimension2d<u32>(iWindowWidth, iWindowHeight), iScreenDepth, bFullScreen); irrw::driver = irrw::device->getVideoDriver(); //.................. } void irrLoadImage(irr::core::stringc szFileName, int iID, int iTextureFlag) { //........ irrw::TextureCollector.push_back(irrw::driver->getTexture(szFileName)); // the call stack pointed to this line irrw::TextureConnector.push_back(iID); } main.cpp: //......... INT WINAPI WinMain(HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT) { //......... irrInit(GD_OPENGL, 800, 600, 16, false); irrLoadImage("picture.jpg", 100, 1); //......... } and the error: Unhandled exception at 0x692804d6 in Game.exe: 0xC0000005: Access violation reading location 0x00000558. Now I really got no idea on how to fix the problem. Any kind of help would be appreciated :) Here are some prototypes: virtual ITexture* getTexture(const io::path& filename) = 0; typedef core::string<fschar_t> path; // under 'io' namespace typedef char fschar_t; typedef string<c8> stringc; typedef char c8; Just FYI, I am using MSVC++ 2008 EE.

  • AJAX, Subdomains and the 200 OK response.

    - by b. e. hollenbeck
    A non-hypothetical but abstracted situation: I have a domain www.foo.com, from which I'm making an AJAX POST to beta.foo.com. Examining the XHR object, I see a response header of 200 OK, but no response text - I even get a response 12B long, which is the exact response (a 12-character string) that I'm expecting - but the response text is blank. If this is a cross-domain issue, why am I getting 200 OK, and better yet - why am I seeing the PHP functions fire on the beta.foo.com side - yet getting no response?

    What regular expression can I use (if any) to validate that a given string is a legal ssh rsa public key? I only need to validate the actual key - I don't care about the key type the precedes it or the username comment after it. Ideally, someone will also provide the python code to run the regex validation. Thanks.

  • WLI domain with 3 servers - issues on JPD process startup

    - by XpiritO
    Hi there. I'm currently working on a clustered WLI environment which comprehends 3 servers: 1 admin server ("AdminServer") and 2 managed servers ("mn1" and "mn2") grouped as a cluster, as follows: Architecture diagram: http://img72.imageshack.us/img72/4112/clusterdiagram.jpg I've developed a JPD process to execute some scheduled tasks, invoked using a Message Broker. I've deployed this project into a single-server WLI domain (with AdminServer only) and it works as expected: the JPD process is invoked (I've configured a Timer Event Generator instance to start it up). Message broker: http://img532.imageshack.us/img532/1443/wlimessagebroker.jpg Timer event generator: http://img408.imageshack.us/img408/7358/wlitimereventgenerator.jpg In order to achieve fail-over and load-balancing capabilities, I'm currently trying to deploy this JPD process into this clustered WLI environment. Although, I'm having some issues with this, as I cannot get it to work properly, even if it still works. Here is a screenshot of the "WLI Process Instance Monitor" (with AdminServer and mn1 instances up and running): http://img710.imageshack.us/img710/8477/wliprocessinstancemonit.jpg According to this screen the process seems to be running, as it shows in this instance monitor screen. However, I don't see any output coming out neither at AdminServer console or mn1 console. In single-server domain it was visible output from JPD process "timeout" callback method, wich implementation is shown below: @com.bea.wli.control.broker.MessageBroker.StaticSubscription(xquery = "", filterValueMatch = "", channelName = "/SamplePrefix/Samples/SampleStringChannel", messageBody = "{x0}") public void subscription(java.lang.String x0) { String toReturn=""; try { Context myCtx = new InitialContext(); MBeanHome mbeanHome = (MBeanHome)myCtx.lookup("weblogic.management.home.localhome"); toReturn=mbeanHome.getMBeanServer().getServerName(); System.out.println("**** executed at **** " + System.currentTimeMillis() + " by: " + toReturn); } catch (Exception e) { System.out.println("Exception!"); e.printStackTrace(); } } (...) @org.apache.beehive.controls.api.events.EventHandler(field = "myT", eventSet = com.bea.control.WliTimerControl.Callback.class, eventName = "onTimeout") public void myT_onTimeout(long time, java.io.Serializable data) { // #START: CODE GENERATED - PROTECTED SECTION - you can safely add code above this comment in this method. #// // input transform System.out.println("**** published at **** " + System.currentTimeMillis()); publishControl.publish("aaaa"); // parameter assignment // #END : CODE GENERATED - PROTECTED SECTION - you can safely add code below this comment in this method. #// } and here is the output visible at "AdminServer" console in single-server domain testing: **** published at **** 1273238090713 **** executed at **** 1273238132123 by: AdminServer **** published at **** 1273238152462 **** executed at **** 1273238152562 by: AdminServer (...) What may be wrong with my clustered configuration? Am I missing something to accomplish clustered deployment? Thanks in advance for your help.
