如何向 Windows Phone 7 发出 POST 请求？

Question

如何发送数据到服务器进行身份验证？使用当前代码：

WebClient MyWebClient = new WebClient();
        MyWebClient.OpenWriteCompleted += new OpenWriteCompletedEventHandler(MyWebClient_OpenWriteCompleted);
        MyWebClient.Headers["User-Agent"] = "Mozilla/4.0 (compatible; ICS)";
        MyWebClient.OpenWriteAsync(new Uri("http://myserver.com/login"), "POST", "[email protected]&pass=mypassword");


    void MyWebClient_OpenWriteCompleted(object sender, OpenWriteCompletedEventArgs e)
    {
        throw new NotImplementedException();
    }

在此代码之后，如果程序嗅探器（HttpAnalyzer）查看标头和响应内容，则响应内容中将写入： 请求未完成。等待...，并且响应标头将为空... 如何发起Post请求？

Answer 1

根据 doc，当您关闭传递给的流时，内容实际上会发送您在 OpenWriteCompleted 事件的参数中。

由于您没有正确关闭流，因此它不会发送任何内容。

Answer 2

//Making a POST request using WebClient.


Function()
{    
  WebClient wc = new WebClient();

  var URI = new Uri("http://your_uri_goes_here");

//如果需要任何编码。

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

//或任何其他编码类型。

//如果需要任何密钥

  wc.Headers["KEY"] = "Your_Key_Goes_Here";

 wc.UploadStringCompleted += new UploadStringCompletedEventHandler(wc_UploadStringCompleted);

 wc.UploadStringAsync(URI,"POST","Data_To_Be_sent");    

}

void wc__UploadStringCompleted(object sender, UploadStringCompletedEventArgs e)

{  

  try            
  {          
     MessageBox.Show(e.Result); 

//e.result 获取针对 POST 请求的响应。

 }

  catch(Exception exc)         
  {             
     MessageBox.Show(exc.ToString());            
  }

}
