  No MediaTypeFormatter is available to read an object of type 'UserToken' from content with media ...

  Aug 09, 2012 05:04 AM|LINK

  Hi all,

  I'm writing a demo Web API app having a class as 

  public class UserToken
      {
          public string UserName { get; set; }
  
          public string Token { get; set; }
      }

  and calling a web api using this HttpClient code:

  client = new HttpClient();
  client.BaseAddress = new Uri("http://xyz.com/");
  client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
  
  HttpResponseMessage response = client.GetAsync("login/" + username + "/" + password).Result;
              if (response.IsSuccessStatusCode) 
              {
                  var userToken = response.Content.ReadAsAsync<UserToken>().Result;
                  token = userToken.Token;
              }

  While debugging, i find that response is coming, but I'm getting exception while it is reading from content as 

      No MediaTypeFormatter is available to read an object of type 'UserToken' from content with media type 'text/html'

  My query here is that when I'm adding Accept as "application/json" in Request-header, then why I'm getting response content as "text.html"?

  Kindly suggest if my understanding is wrong here.

  Debug the network call with fiddler and make sure you're getting back the response you expect. My guess is that you're calling the wrong controller (perhaps a MVC controller and not a WebAPI controller thus the HTML?).

  Hi Brock,

  Its done! I was calling a wrong http link... Sorry my bad.

  But then aslo I was missing Proxy settings in the client configuration, which I resolved with adding HttpClientHandler ans setting proxy as 

  var handler = new HttpClientHandler(){
      Proxy = HttpWebRequest.GetSystemWebProxy()
  };
  
  client = new HttpClient(handler);

  Thanks for response!
