Question

我在将HttpWebRequest发送到特定网址时遇到问题。生成响应但不是我想要的。它会给出类似＆＃34;会话超时的响应！请登录以继续＆＃34;。然而，当我通过Python 3.4发送相同的请求时，它会给我所需的响应。响应就像＆＃34; - 有些html在这里 - ＆＃34;我想要的。

我不知道为什么会这样，因为我不想通过C＃来做。

CodeBehind（给出错误的回复）是：

    string postData = "somequerystring";
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("someurl");
    request.KeepAlive = true;
    request.ProtocolVersion = HttpVersion.Version10;
    request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36";
    request.Method = "POST";
    byte[] byteArray = Encoding.UTF8.GetBytes(postData);
    request.ContentType = "application/x-www-form-urlencoded";
    request.ContentLength = byteArray.Length;
    request.Headers.Add(HttpRequestHeader.CacheControl, "no-cache");
    using (var dataStream = request.GetRequestStream())
    {
        dataStream.Write(byteArray, 0, byteArray.Length);
    }
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    string responseFromServer = new StreamReader(response.GetResponseStream()).ReadToEnd();     
    response.Close(); 
    Context.Response.Write(responseFromServer);

Python脚本（给出正确的答案）是：

import requests
url = "someurl"
payload = "somequerystring"
headers = {
'content-type': "application/x-www-form-urlencoded"
}

response = requests.request("POST", url, data=payload, headers=headers)
print(response.text)

帮帮我吧？
