如何在Windows手机设定的时间出HTTP客户端请求的操作8.1 / 8.1的Windows [英] How to set time out for http client request operation in windows phone 8.1/Windows 8.1

问题描述

如何超时属性设置为HttpClient的操作。我使用的代码示例是低于

 公开的HttpClient HttpClient的; 
公共CancellationTokenSource CTS; 
 
公共无效sendRequest将（addressUri，postrequestbody）
 {
 HttpHelper.CreateHttpClient（参见HttpClient的）; 
 CTS =新CancellationTokenSource（）; 
 HttpRequestMessage味精= 
新HttpRequestMessage（新列举HTTPMethod（POST），
新的URI（addressUri））; 
 msg.Content =新HttpStringContent（postrequestbody）; 
 msg.Content.Headers.ContentType = 
新HttpMediaTypeHeaderValue（应用/ JSON）; 
 HttpResponseMessage响应= 
等待httpClient.SendRequestAsync（MSG）.AsTask（）; 
 
如果（response.StatusCode == HttpStatusCode.Ok）
 {
} 
} 
  

解决方案

使用的CancellationToken ：

 试
 {
 CancellationTokenSource CTS =新CancellationTokenSource（2000年）; //2秒
 HttpClient的客户端=新的HttpClient（）; 
 HttpResponseMessage响应=等待
 client.SendRequestAsync（要求）.AsTask（cts.Token）; 
} 
赶上（TaskCanceledException前）
 {
 //捕获操作中止... 
} 
  

How to set Timeout property to HttpClient operation. The code sample I used is below.

public HttpClient httpClient;
public CancellationTokenSource cts;

Public void SendRequest(addressUri,postrequestbody)
{
    HttpHelper.CreateHttpClient(ref httpClient);
    cts = new CancellationTokenSource();
    HttpRequestMessage msg = 
        new HttpRequestMessage(new HttpMethod("POST"), 
                               new Uri(addressUri));
    msg.Content = new HttpStringContent(postrequestbody);
    msg.Content.Headers.ContentType = 
        new HttpMediaTypeHeaderValue("application/json");
    HttpResponseMessage response = 
        await httpClient.SendRequestAsync(msg).AsTask();

    if (response.StatusCode == HttpStatusCode.Ok)
    {
    }
}

解决方案

Use a CancellationToken:

try 
{
    CancellationTokenSource cts = new CancellationTokenSource(2000); // 2 seconds
    HttpClient client = new HttpClient();
    HttpResponseMessage response = await
        client.SendRequestAsync(request).AsTask(cts.Token);
}
catch (TaskCanceledException ex)
{
    // Catch operation aborted ...
}
