[英]using cookies (httpWebRequest,c#)
我在網站上閱讀了有關httpWebRequest和Cookies的完整答案,但是我的問題仍然沒有解決。 我有一個winform應用程序登錄到網站(正確登錄),但是我不能使用它的cookie來登錄另一個頁面,我嘗試了許多解決方案,例如使用PHPSESSID,在兩個請求中都使用一個CookieContainer,但都沒有是有效的。 這是我的代碼:
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("(Login page)");
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.KeepAlive = true;
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] data = encoding.GetBytes("username=uname&password=pass&submit=Button");
webRequest.ContentLength = data.Length;
CookieContainer CookieContainer = new CookieContainer();
webRequest.CookieContainer = CookieContainer;
Stream newStream = webRequest.GetRequestStream();
newStream.Write(data, 0, data.Length);
newStream.Close();
HttpWebResponse webResponse;
webResponse = (HttpWebResponse)webRequest.GetResponse();
HttpWebRequest webRequest1 = (HttpWebRequest)WebRequest.Create("(My control panel page)");
webRequest1.Method = "GET";
webRequest1.KeepAlive = true;
webRequest1.CookieContainer=new CookieContainer();
foreach (Cookie cook in webResponse.Cookies)
{
webRequest1.CookieContainer.Add(cook);
}
webRequest.ContentType = "application/x-www-form-urlencoded";
webResponse = (HttpWebResponse)webRequest1.GetResponse();
string html;
using (Stream strmresponse = webResponse.GetResponseStream())
{
using (StreamReader reader = new StreamReader(strmresponse, Encoding.UTF8))
{
html = reader.ReadToEnd();
}
}
textBox1.Text = html;
不知道您是否仍然在乎,但是請檢查出此問題的答案,因為它顯示了如何將Cookie重復用於多個請求。
