我有一些非常簡單的代碼，我一直在Windows 8商店應用程序中使用沒有任何問題。但是，當我與Windows Phone應用程序共享代碼它只是永遠掛起。見下面的示例。這會調用任何網址並以字符串的形式返回其源。帖子和get方法都以相同的方式掛起。任何幫助非常感謝，謝謝。HttpClient任務無法啓動
public static string GetWebSource(string Url)
{
HttpClient client = new HttpClient();
Task<HttpResponseMessage> Resp = client.GetAsync(Url);
//code hangs on following line forever
//Resp.status always stays at waiting for activation
Task.WaitAll(Resp);
if (Resp.Result.IsSuccessStatusCode)
{
Task<string> response = Resp.Result.Content.ReadAsStringAsync();
Task.WaitAll(response);
return response.Result;
}
return "";
}
public static string PostWebSource(string Url, string data)
{
HttpClient client = new HttpClient();
StringContent sc = new StringContent(data);
Task<HttpResponseMessage> Resp = client.PostAsync(Url, sc);
//code hangs on following line forever
//Resp.status always stays at waiting for activation
Resp.Wait();
if (Resp.Result.IsSuccessStatusCode)
{
Task<string> response = Resp.Result.Content.ReadAsStringAsync();
Task.WaitAll(response);
return response.Result;
}
return "";
}
