  send customized error description fro web api

  Jan 21, 2013 06:42 AM|LINK

  i am having a client (mvc4) from where i am calling a web api method to add user.

  [HttpPost]
          public async Task<ActionResult> Create(User user, List<string> rolesList)
          {
              try
              {
                  HttpClient client = new HttpClient();
                  user.Roles = new List<Role>();
  
                  foreach (string roleSelected in rolesList)
                  {
                      user.Roles.Add(new Role() { RoleId = "", RoleName = roleSelected });
                  }
                  user.Application = new BusinessEntities.Application();
                  user.Application.ApplicationName = AppConfig.ApplicationName;
                  JavaScriptSerializer serializer = new JavaScriptSerializer();
                  String contentStr = serializer.Serialize(user);
                  StringContent content = new StringContent(contentStr, Encoding.UTF8, "application/json");
  
                  HttpResponseMessage postResponse = await client.PostAsync(AppConfig.userUrl, content);
                  postResponse.EnsureSuccessStatusCode();
  
                  return RedirectToAction("Index");
              }
              catch (Exception)
              {
              }
         }

  if the user could not be created then postResponse will not be ensuring success code. how can i read the value from Response message ?

  My api method :-

   public HttpResponseMessage Post([FromBody]User user)
          {
              UserBusinessRules userBusiness = new UserBusinessRules();
              string result = userBusiness.AddUser(user);
  
              HttpStatusCode message = new HttpStatusCode();
              if (result.Equals("Success"))
                  message = HttpStatusCode.Created;
              else
                  message = HttpStatusCode.BadRequest;
              return Request.CreateResponse(message, result);
          }

  in this, result is having reason, that why could not the user be created ?

  any idea to read the customized error message from httpresponsemessage ?
