c# - Windows 应用商店应用 httpClient json

Question

我正在尝试在 C# Windows Store App 中获取 json。这是我的代码

client = new HttpClient(); 
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get,  "http://192.168.1.105:8080/button.json");
request.Headers.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"))

我得到“System.Net.WebException：服务器违反了协议。Section=ResponseStatusLine”

我也试过

System.Net.WebException: The server committed a protocol violation. Section=ResponseStatusLine
