我正在尝试在 Youtube 上发表评论并获得 xml 响应（这样我可以获得评论 ID，或者如果我需要输入验证码或其他内容），但我只能发表评论。由于某种原因，我无法使用 .xml 读取 xml 响应response.GetResponseStream()。当我尝试将响应输出到控制台时，我什么也得不到。而且，我已经嗅探了我的程序使用 Wireshark 发送和接收的请求和响应，我可以看到 xml 在响应中。
这是我用来读取响应的代码：
using (HttpWebResponse response = MakeRequest(request, cookies, post))
{
using (var reader = new System.IO.StreamReader(response.GetResponseStream(), UTF8Encoding.UTF8))
{
string xml = reader.ReadToEnd();
Console.WriteLine(xml);
}
}
和 MakeRequest 函数
private static HttpWebResponse MakeRequest(HttpWebRequest request, CookieContainer SessionCookieContainer, Dictionary<string, string> parameters = null)
{
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.52 Safari/536.5Accept: */*";
request.Accept = "text/html,text/xml,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
request.CookieContainer = SessionCookieContainer;
request.AllowAutoRedirect = false;
request.KeepAlive = true;
if (proxy != "") request.Proxy = myproxy;
if (parameters != null) request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
string postData = string.Empty;
if (parameters != null)
{
postData = getPostData(parameters);
byte[] postBuffer = UTF8Encoding.UTF8.GetBytes(postData);
using (Stream postStream = request.GetRequestStream())
{
postStream.Write(postBuffer, 0, postBuffer.Length);
}
}
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
SessionCookieContainer.Add(response.Cookies);
while (response.StatusCode == HttpStatusCode.Found)
{
response.Close();
request = GetNewRequest(response.Headers["Location"], SessionCookieContainer);
response = (HttpWebResponse)request.GetResponse();
SessionCookieContainer.Add(response.Cookies);
}
return response;
}
关于为什么这不起作用以及如何解决这个问题的任何想法？
