Windows phone的HttpClient的PostAsync没有响应挂 [英] Windows phone HttpClient PostAsync hang with no response

问题描述

我有呼吁从WP application.The PostAsync的的HttpClient post方法的问题总是挂起，不给出任何response.The同一code ++工程，当我从WPF应用程序尝试。下面是我在做什么：

服务器Web API code

 公共类GameController：ApiController
{
[HttpPost]公共GameDto CreateGame（GameDto gameDto）
        {
            尝试
        {
            游戏管理BL =新游戏管理（）;
            gameDto = bl.CreateGame（gameDto）;
            返回gameDto;
        }
        赶上（例外）
        {            扔;
        }
    }
}
 

客户端WP8 code从类库调用

 专用异步无效Button_Click（对象发件人，RoutedEventArgs E）
        {
            尝试
            {
 HttpClient的客户端=新的HttpClient（）;
client.BaseAddress =新的URI（HTTP：//本地主机：59580）;
            client.DefaultRequestHeaders.Accept.Add（
                新MediaTypeWithQualityHeaderValue（应用/ JSON））;
GameDto newGame =新GameDto（）;
                newGame.CreatedBy = 1;
            newGame.Name = txtGameName.Text;
            newGame.GameTypeId =（INT）cmbGameType.SelectedValue;
             MediaTypeFormatter jsonFormatter =新JsonMediaTypeFormatter（）;
             VAR响应=等待client.PostAsync＆LT; GameDto＆GT;（API /游戏/ CreateGame，newGame，jsonFormatter）;
            response.EnsureSuccessStatus code（）; //扔在错误code。
            VAR userDto =等待response.Content.ReadAsAsync＆LT; GameDto＆GT;（）;
            //_products.CopyFrom(products）;
            MessageBox.Show（userDto.Id.ToString（））;
        }
        赶上（例外）
        {            扔;
        }    }

使用ConfigureAwait

  VAR的结果=等待httpClient.GetStreamAsync（weeklyplan）
                         .ConfigureAwait（continueOnCapturedContext：假）;
 

I am having problem in calling the HttpClient post method from WP application.The PostAsync always hangs and does not give any response.The same code works when i try it from WPF application. Here is what I am doing:

Server Web API code

public class GameController : ApiController
{
[HttpPost]

public GameDto CreateGame(GameDto gameDto)
        {
            try
        {
            GameManager bl = new GameManager();
            gameDto = bl.CreateGame(gameDto);
            return gameDto;
        }
        catch (Exception)
        {

            throw;
        }
    }
}

Client WP8 code calling from class library

private async void Button_Click(object sender, RoutedEventArgs e)
        {
            try
            {


 HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost:59580");
            client.DefaultRequestHeaders.Accept.Add(
                new MediaTypeWithQualityHeaderValue("application/json"));               
GameDto newGame = new GameDto();
                newGame.CreatedBy = 1;
            newGame.Name = txtGameName.Text;
            newGame.GameTypeId = (int)cmbGameType.SelectedValue;
             MediaTypeFormatter jsonFormatter = new JsonMediaTypeFormatter();
             var response = await client.PostAsync<GameDto>("api/Game/CreateGame", newGame, jsonFormatter);
            response.EnsureSuccessStatusCode(); // Throw on error code.
            var userDto = await response.Content.ReadAsAsync<GameDto>();
            //_products.CopyFrom(products);
            MessageBox.Show(userDto.Id.ToString());
        }
        catch (Exception)
        {

            throw;
        }

    }

解决方案

Checkout This Answer res.olved my issue. Use ConfigureAwait

var result = await httpClient.GetStreamAsync("weeklyplan")
                         .ConfigureAwait(continueOnCapturedContext:false);
