【CSharp】 WebBrowser的Cookie操作

作者:天楚 / 发布于2015/10/8/ 426


	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);

	
	2. 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();
