问题
My problem is that I get 0 bytes response from server (I'm using Fiddler2 to check this out).
Picture:
What I'm doing:
- Log in. I get cookies.
- Creating thread
public void CreateTopic(string subject, string message, string forumId)
{
HttpWebResponse response = null;
string source = string.Empty;
string lastClick= string.Empty;
string creationTime= string.Empty;
string formToken = string.Empty;
// GET
while(true)
{
webRequest =
(HttpWebRequest) HttpWebRequest.Create(Url + "posting.php?mode=post&f=" + forumId + "&sid=" + sid);
webRequest.KeepAlive = true;
webRequest.Method = "GET";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Host = Url.Replace("http://", "").Replace("/", "");
webRequest.CookieContainer = cookieJar;
ServicePointManager.Expect100Continue = false;
try
{
response = (HttpWebResponse) webRequest.GetResponse();
UpdateSid(Url + "posting.php?mode=post&f=" + forumId + "&sid=" + sid);
}
catch (Exception ex)
{
continue;
}
break;
}
StreamReader streamReader = new StreamReader(response.GetResponseStream());
source = streamReader.ReadToEnd();
streamReader.Close();
response.Close();
// Get stuff
// last click
Match lastClickMatch = Regex.Match(source, "name=\"lastclick\" value=\"([0-9]{10})\" />");
if (lastClickMatch.Success) lastClick = lastClickMatch.Groups[1].Value;
// creation time
Match creationTimeMatch = Regex.Match(source, "name=\"creation_time\" value=\"([0-9]{10})\" />");
if (creationTimeMatch.Success) creationTime = creationTimeMatch.Groups[1].Value;
// form token
Match formTokenMatch = Regex.Match(source, "name=\"form_token\" value=\"(.{40})\" />");
if (formTokenMatch.Success) formToken = formTokenMatch.Groups[1].Value;
// POST
webRequest = (HttpWebRequest)WebRequest.Create(Url + "posting.php?mode=post&f=" + forumId + "&sid=" + sid);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Host = Url.Replace("http://", "").Replace("/", "");
webRequest.CookieContainer = cookieJar;
string data = "icon=&subject=" + Encode(subject) + "&addbbcode20=100&message=" + Encode(message) + "&attach_sig=on&post=Submit&lastclick=" + lastClick + "&creation_time=" + creationTime + "&form_token=" + formToken;
byte[] byte1 = Encoding.UTF8.GetBytes(data);
webRequest.ContentLength = byte1.Length;
ServicePointManager.Expect100Continue = false;
Stream stream = webRequest.GetRequestStream();
stream.Write(byte1, 0, byte1.Length);
stream.Close();
response = (HttpWebResponse)webRequest.GetResponse();
UpdateSid(Url + "posting.php?mode=post&f=" + forumId + "&sid=" + sid);
response.Close();
}
I get this on fiddler: RAW:

Response RAW:

I have no idea what is going on. If you will help me I will be grateful. I'm sorry for my English.
回答1:
I found this snippet in the source of phpBB 3.0.9:
203 // Check permissions
204 if ($user->data['is_bot'])
205 {
206 redirect(append_sid("{$phpbb_root_path}index.$phpEx"));
207 }
So they might be pulling you a trick here. Are you sure you are allowed to do what you're trying to?
Anyhow, I think you might to want to change your user agent:
webRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.36 Safari/535.7";
This might help not being identified as a bot, which perhaps takes place because the default UserAgent
value is null
.
回答2:
I found out why it didn't create thread. It checks:
if ($user->data['is_bot'])
If you don't want to be a bot, then you have to WAIT for like 8 seconds before sending POST:
Thread.Sleep(8100);
It resolved all problems for me.
回答3:
Its returning a status code of 302 Found, which means the server is attempting to redirect you to another page (in your example, "http://stuff.com/games.html").
