wp7上的网络错误

本文介绍了wp7上的网络错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试构建并运行几个月前在wp7上运行良好的旧应用程序，但是http客户端都没有为我工作。

I'm trying to build and run old application which worked fine several month ago on wp7, however none of http clients works for me.

首先，我m尝试 HttpWebRequest

var httpWebRequest = (HttpWebRequest)WebRequest.Create(url); httpWebRequest.Method = HttpMethod.Get; httpWebRequest.Accept = "application/json"; var response = (HttpWebResponse)await httpWebRequest.GetResponseAsync();

它抛出异常

The remote server returned an error: NotFound.

然后我尝试 HttpClient

Uri theUri = new Uri("www.google.fi/"); HttpClient aClient = new HttpClient(); aClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); aClient.DefaultRequestHeaders.Host = theUri.Host; //Post the data HttpResponseMessage aResponse = await aClient.PostAsync(theUri, new StringContent(postData)); if (aResponse.IsSuccessStatusCode) { return aResponse.Content.ToString(); } else { // show the response status code return "HTTP Status: " + aResponse.StatusCode.ToString() + " - Reason: " + aResponse.ReasonPhrase; }

它返回

System.Net.HttpStatusCode.NotFound

看起来像手机不能到达网络...虽然：

Looking like phone cant reach network at all... Though:

我当前的方法（通过HttpWebRequest）绝对有效

我绝对有网络访问权限，因为其他网络应用程序或多或少都可以。

BONUS：wp8上的同一个应用程序运行正常。所以服务器完全可用，请求有效。

EDIT1： here here here / a>类似的问题，添加

found here a similar issue, added

client.Headers["Content-Type"] = "application/x-www-form-urlencoded"; client.Encoding = Encoding.UTF8;

但仍然出现同样的错误。

but still getting same error.

EDIT2：制作了一个新的wp7项目，添加了Bcl.Async和HttpClient。仍然是同样的问题。

made a fresh wp7 project, added Bcl.Async and HttpClient. Still the same problem.

EDIT3：昨晚研究：

last night research:

在wp7设备上运行正常：

on wp7 device this works ok:

var client = new RestClient("example"); var request = new RestRequest(String.Empty, Method.GET); client.GetAsync(request, (_response, _handle) => { var resource = _response; var content = resource.Content; });

但是当我切换到我的服务器时，它会在wp7设备上抛出NotFound异常。在wp8设备上，它返回正确的结果。

But when i'm switching to my server, it throws NotFound exception on wp7 device. On wp8 device it returns correct result.

推荐答案

重置为出厂设置有帮助。

Resetting to factory settings helped.
