C# 使用Windows Phone 8.1的HttpClient
可能听起来像个傻瓜，但这个问题并没有从我的脑海中消失。我正面临有关Windows Phone 8.1的奇怪问题。我为WindowsPhone8开发了一个应用程序，它与网关服务器通信并处理请求的数据。我们使用HttpClient向网关服务器发送/接收数据。但是，由于某些原因，我将Windows Phone 8操作系统升级为Windows Phone 8.1，但现在，每当我与网关服务器通信时，它都不会处理请求 不过，它在Windows 8.1 Emulator上运行良好，但在以前从Windows Phone 8.0操作系统升级的实际Windows Phone 8.1设备上部署应用程序时不起作用 而且 var response=await RequestUtility.SendHttpRequestmyUri，httpMethod，stream，text/xml，null，null，0；在Windows Phone 8.1上运行此应用程序时，响应始终包含0字节 下面是与服务器通信的代码片段 请求实用程序代码段C# 使用Windows Phone 8.1的HttpClient,c#,windows-phone-8,windows-phone-8.1,windows-phone-8-emulator,C#,Windows Phone 8,Windows Phone 8.1,Windows Phone 8 Emulator,可能听起来像个傻瓜，但这个问题并没有从我的脑海中消失。我正面临有关Windows Phone 8.1的奇怪问题。我为WindowsPhone8开发了一个应用程序，它与网关服务器通信并处理请求的数据。我们使用HttpClient向网关服务器发送/接收数据。但是，由于某些原因，我将Windows Phone 8操作系统升级为Windows Phone 8.1，但现在，每当我与网关服务器通信时，它都不会处理请求 不过，它在Windows 8.1 Emulator上运行良好，但在以前从Windows P
有什么想法吗？如果您有任何想法/建议，我们将不胜感激 我更喜欢使用httpwebrequest和httpwebresponse类来执行对服务器的简单请求，请使用以下命令：
private async Task<string> DoRequest(string Type, string Device, string Version, string Os)
{
//Declarations of Variables
string result = "";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.ContinueTimeout = 4000;
request.Credentials = CredentialCache.DefaultNetworkCredentials;
//Add headers to request
request.Headers["Type"] = Type;
request.Headers["Device"] = Device;
request.Headers["Version"] = Version;
request.Headers["Os"] = Os;
request.Headers["Cache-Control"] = "no-cache";
request.Headers["Pragma"] = "no-cache";
using (HttpWebResponse response = (HttpWebResponse)await request.GetResponseAsync())
{
if (response.StatusCode == HttpStatusCode.OK)
{
//To obtain response body
using (Stream streamResponse = response.GetResponseStream())
{
using (StreamReader streamRead = new StreamReader(streamResponse, Encoding.UTF8))
{
result = streamRead.ReadToEnd();
}
}
}

return result;

你能用这个吗？祝你好运 如果它在模拟器中工作，但在设备中不工作，我会检查看看有什么可能不同。手机升级正常吗？它是否遇到任何其他连接问题？您是否尝试过创建一个新项目并测试一个简单的HttpRequest？我也有同样的问题，我的代码在Windows 8.1上运行得很好，但在Windows Phone 8.1空响应内容中不行>您解决了这个问题吗？
