cordova - Image upload using FileTransfer.Upload to ASP.NET REST API -

i trying implement android app using phonegap ionic framework. requirement upload image gallery remote server. achieve implemented asp.net rest api upload image server. (let assume url upload: http://xxxx.net/api/upload). inside rest api implemented uploadcontroller:webcontroller. has post() method looks below.

server code:

public string post() {     httppostedfile myfile = httpcontext.current.request.files["recfile"];     if (myfile == null)         return null;     return utils.uploadtoserver(file); } 

my android code looks below:

$scope.uploadpictureex = function() {     var options = new fileuploadoptions();     options.filekey="recfile";       options.filename=$scope.emplyeedata.imageuri.substr($scope.emplyeedata.imageuri.lastindexof('/')+1);     options.mimetype="image/jpeg";     var params = new object();     params.value1 = "test";     params.value2 = "param";     options.params = params;     options.chunkedmode = false;     options.httpmethod = "post";     options.headers = {             connection: "close"     };     var ft = new filetransfer();     ft.upload($scope.emplyeedata.imageuri, "http://xxxx.net/api/upload/", win, fail, options); } 

thats it. when execute getting error saying error code = 3. can 1 please let me know how done? approach of implementing web api correct? doing thing wrong? thanks!!

have enabled cors in web api ?

install-package microsoft.aspnet.webapi.cors 

and in web api config:

public static class webapiconfig {     public static void register(httpconfiguration config)     {         // new code         config.enablecors();          config.routes.maphttproute(             name: "defaultapi",             routetemplate: "api/{controller}/{id}",             defaults: new { id = routeparameter.optional }         );     } } 

and in controller can fine-grain control want enable:

[enablecors(origins: "http://mywebclient.azurewebsites.net", headers: "*", methods: "*")] public class testcontroller : apicontroller {     // controller methods not shown... }
