c# - Enable CORS in Web API 2 -


i have client , server running on different ports. server running web api 2 (v5.0.0-rc1).

i tried installing microsoft asp.net web api cross-origin support package , enabled in webapiconfig.cs. gives me enablecors() function, package installed correctly.

here can see register() function in webapiconfig.cs:

public static void register(httpconfiguration config) {     config.maphttpattributeroutes();      var cors = new enablecorsattribute("*", "*", "*");     config.enablecors(cors); }

get requests work fine. when sending post, following:

options http://localhost:19357/api/v1/rooms? 404 (not found) angular.js:10159 options http://localhost:19357/api/v1/rooms? origin http://localhost:8000 not allowed access-control-allow-origin. angular.js:10159 xmlhttprequest cannot load http://localhost:19357/api/v1/rooms. origin http://localhost:8000 not allowed access-control-allow-origin.

according fiddler sends options request. doesn't issue post afterwards.

so i'm guessing config.enablecors(cors); in webapiconfig.cs isn't doing anything, leads server denying client/browser send post request.

do have idea how solve problem?

edit 05.09.13 has been fixed in 5.0.0-rtm-130905

cors works absolutely fine in microsoft.aspnet.webapi.cors version 5.2.2. following steps configured cors charm me:

  1. install-package microsoft.aspnet.webapi.cors -version "5.2.2" // run package manager console

  2. in global.asax, add following line: before mvc route registrations

    globalconfiguration.configure(webapiconfig.register);

  3. in webapiconfig register method, have following code:

    public static void register(httpconfiguration config) {     config.enablecors();     config.maphttpattributeroutes(); }

in web.config, following handler must first 1 in pipeline:

<add name="extensionlessurlhandler-integrated-4.0" path="*." verb="*" type="system.web.handlers.transferrequesthandler" precondition="integratedmode,runtimeversionv4.0" />

in controller derived apicontroller, add enablecorsattribute:

[enablecors(origins: "*", headers: "*", methods: "*")] // tune needs [routeprefix("")] public class mycontroller : apicontroller

that should set nicely!
