[英]using cookies (httpWebRequest,c#)
我在网站上阅读了有关httpWebRequest和Cookies的完整答案,但是我的问题仍然没有解决。 我有一个winform应用程序登录到网站(正确登录),但是我不能使用它的cookie来登录另一个页面,我尝试了许多解决方案,例如使用PHPSESSID,在两个请求中都使用一个CookieContainer,但都没有是有效的。 这是我的代码:
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,但是请检查出此问题的答案,因为它显示了如何将Cookie重复用于多个请求。
