通過HttpClient登錄

Question

我正在使用此代碼來使用ASP.NET MVC 5 WebAPI2。

static async Task RunAsync() 
     { 
      using (var client = new HttpClient()) 
      { 
       client.BaseAddress = new Uri("http://localhost:52967/"); 
       client.DefaultRequestHeaders.Accept.Clear(); 
       client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

       // New code: 
       HttpResponseMessage response = await client.GetAsync("api/Account/Login"); 
       if (response.IsSuccessStatusCode) 
       { 
        var data = await response.Content.ReadAsStringAsync(); 

       } 
      } 
     } 

在AccountController我創建了下面的方法

[HttpPost] 
     [AllowAnonymous] 
     [Route("Login")] 
     public HttpResponseMessage Login(string username, string password) 
     { 
      try 
      { 
       var identityUser = UserManager.Find(username, password); 

       if (identityUser != null) 
       { 
        var identity = new ClaimsIdentity(Startup.OAuthOptions.AuthenticationType); 
        identity.AddClaim(new Claim(ClaimTypes.Name, username)); 

        AuthenticationTicket ticket = new AuthenticationTicket(identity, new AuthenticationProperties()); 
        var currentUtc = new SystemClock().UtcNow; 
        ticket.Properties.IssuedUtc = currentUtc; 
        ticket.Properties.ExpiresUtc = currentUtc.Add(TimeSpan.FromMinutes(1440)); 

        var token = Startup.OAuthOptions.AccessTokenFormat.Protect(ticket); 

        var response = new HttpResponseMessage(HttpStatusCode.OK) 
        { 
         Content = new ObjectContent<object>(new 
         { 
          UserName = username, 
          ExternalAccessToken = token 
         }, Configuration.Formatters.JsonFormatter) 
        }; 

        return response; 


       } 
      } 
      catch (Exception) 
      { 
      } 

      return new HttpResponseMessage(HttpStatusCode.BadRequest); 
     } 

我需要通過用戶名和密碼，不知何故。任何線索？

       var responseJson = await responseMessage.Content.ReadAsStringAsync(); 
       var jObject = JObject.Parse(responseJson); 
       var token = jObject.GetValue("access_token").ToString();
