HttpWebRequest/HttpResponse: How to send data in the response?
提问by user252816
I have a client and a server.
我有一个客户端和一个服务器。
On the client side I have:
在客户端，我有：
HttpWebRequest request =
(HttpWebRequest)WebRequest.Create("http://localhost/fa/Default.aspx");
request.Method = "POST";
byte[] data = Encoding.ASCII.GetBytes(GetSAMLRequestB64());
request.ContentType = "text/xml";
request.ContentLength = data.Length;
Stream stream = request.GetRequestStream();
stream.Write(data, 0, data.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
On the server side I have:
在服务器端，我有：
public void ProcessRequest(HttpContext httpContext)
{
HttpResponse response = httpContext.Response;
response.Clear();
response.BufferOutput = true;
response.StatusCode = 200; // HttpStatusCode.OK;
response.Write("Hello");
response.ContentType = "text/xml";
response.End();
}
The client receives the response with the correct StatusCode. Although, if I do (int)response.ContentLength;on the client I get 0. I can't read the string "Hello" after I receive the response (client side).
客户端收到带有正确StatusCode. 虽然，如果我(int)response.ContentLength;在客户端上这样做，我会得到 0。在收到响应（客户端）后，我无法读取字符串“Hello”。

Perhaps setting the content type before the actual write or flushing the stream would help.
也许在实际写入或刷新流之前设置内容类型会有所帮助。

You didn't set ContentLength on the server. Maybe that would help?
您没有在服务器上设置 ContentLength。也许这会有所帮助？
