c# - Cannot get response from WebAPI -


update : have better understanding of error. facing error explained here : https://stackoverflow.com/a/20035319/3021830. should fix.

i have rest api created asp.net webapi. hosted on http://localhost:54700/. have method route "api/refdata", need call http://localhost:54700/api/refdata. marked allowanonymous attribute

when make call postman seems work fine. try call asp.net mvc application, both server , client can not result.

my server side code : 

private static httpclient _client; private static httpclient client {         {         if (_client == null)         {             _client = new httpclient();             _client.baseaddress = new uri("http://localhost:54700/");             _client.defaultrequestheaders.accept.clear();             _client.defaultrequestheaders.accept.add(new mediatypewithqualityheadervalue("application/json"));          }         return _client;     } }   internal list<heardabout> heardabouts {         {         if (system.web.httpcontext.current.session["refdata"] == null)         {             getrefdata().wait();         }         return system.web.httpcontext.current.session["refdata"] list<refdata>;     } }  private async task<list<refdata>> getrefdata() {     try     {         list<refdata> has = new list<refdata>();         // following line code leaves debugging         httpresponsemessage response = await client.getasync("api/refdata");         if (response.issuccessstatuscode)         {             has = await response.content.readasasync<list<refdata>>();             system.web.httpcontext.current.session["refdata"] = has;         }         return has;     }     catch (exception ex)     {         throw;     } }

and client side code is:

$.ajax({     type: "get",     url: "http://localhost:54700/api/refdata",     cache: false,     contenttype: "application/json; charset=utf-8",     success: function (response) {         if (callback)             callback(response.d);     },     error: function (response) {         if (callback)             error(response.d);     }, });

the server-side codes reaches commented line. leaves debugging. wrapped code try-catch block not raise exception well.

the client-side code falls error statustext "error".

what wrong these codes , how may fix?

thanks in advance.

as have denoted in update calls failed because domain addresses of web application , webapi different.

to solve problem have used information provided here : enabling cross-origin requests in asp.net web api 2. , works.
