webbrower控件，如何获取cookies

1.在WebBrowser中获取Cookie

CookieContainer myCookieContainer = new CookieContainer();

string cookieStr = webBrowser1.Document.Cookie; string[] cookstr = cookieStr.Split(';'); foreach (string str in cookstr) { string[] cookieNameValue = str.Split('='); Cookie ck = new Cookie(cookieNameValue[0].Trim ().ToString(), cookieNameValue[1].Trim ().ToString()); ck.Domain = "www.google.com "; myCookieContainer.Add(ck); }

WebClient设置cookie! WebClient wc = new WebClient(); wc.Headers.Add("Cookie", "PHPSESSID=" + cookie + ";"); // 注意，这里是Cookie，不是Set-Cookie byte[] re = wc.UploadData(Global.RootPath + "test.PHP", new byte[0]); System.Text.UTF8Encoding converter = new System.Text.UTF8Encoding(); string str = converter.GetString(re);

1. 在WebBrowser中设置Cookie public partial class WebBrowserControl : Form { private String url;

   [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
   public static extern bool InternetSetCookie(string lpszUrlName, string lbszCookieName, string lpszCookieData);
   
   public WebBrowserControl(String path)
   {
       this.url = path;
       InitializeComponent();
   
       // set cookie
       InternetSetCookie(url, "JSESSIONID", Globals.ThisDocument.sessionID);
   
       // navigate
       webBrowser.Navigate(url);
   }        
   

}

3.将WebBrowser的cookie信息传给HttpWebRequest

先建一个"CookieContainer" 把WebBrowser中的Cookie保存在里面

//在WebBrowser中登录cookie保存在WebBrowser.Document.Cookie中
CookieContainer myCookieContainer = new CookieContainer();

//String 的Cookie　要转成　Cookie型的　并放入CookieContainer中 string cookieStr = webBrowser1.Document.Cookie; string[] cookstr = cookieStr.Split(';');

foreach (string str in cookstr) { string[] cookieNameValue = str.Split('='); Cookie ck = new Cookie(cookieNameValue[0].Trim().ToString(), cookieNameValue[1].Trim().ToString()); ck.Domain = "www.abc.com";// 必须写对 myCookieContainer.Add(ck); }

HttpWebRequest hreq = (HttpWebRequest)HttpWebRequest.Create("http://www.abc.com/search.asp "); hreq.Method = "POST"; hreq.ContentType = "application/x-www-form-urlencoded";

//自己创建的CookieContainer hreq.CookieContainer = myCookieContainer;

string postdata = "id=2005&action=search&name="; byte[] byte1 = Encoding.ASCII.GetBytes(postdata); hreq.ContentLength = byte1.Length;

Stream poststream = hreq.GetRequestStream(); poststream.Write(byte1, 0, byte1.Length); poststream.Close();

HttpWebResponse hres = (HttpWebResponse)hreq.GetResponse(); 转载于：https://blog.csdn.net/hkwlg1314/article/details/52187200
