捕获 HTTP 响应时出现问题

Question

我有这段代码可以成功发出 HTTP 请求：

                //Successful request
                var requestInBytes = encoding.GetBytes(urlWithParameters.ToString());

                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(urlWithParameters.ToString());
                req.Method = "POST";
                req.ContentLength = requestInBytes.Length;
                req.ContentType = "application/x-www-form-urlencoded";

                Stream newStream = req.GetRequestStream();

                // Send the data.
                newStream.Write(requestInBytes, 0, requestInBytes.Length);
                newStream.Close();

但是，我在捕获响应时遇到了问题。现在，我正在尝试这样做：

            //No response?
            System.IO.StreamReader st = new StreamReader(((HttpWebResponse)req.GetResponse()).GetResponseStream());
            var response = st.ReadLine();

但这会带来空白响应吗？

Answer 1

尝试：

HTTPWebResponse response = req.GetResponse();

然后您可以检查响应的各种属性。

或者

尝试：

var response= req.ReadToEnd();
