| WebBrowser Cookie Operation 1. Obtaining Cookies in WebBrowser 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 setting cookie!
WebClient WC = new WebClient ();
Wc. Headers.add ("Cookie", "phpsessid=" + cookie + ";");
Note that this is a Cookie, not a 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. Setting a cookie in WebBrowser
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. Pass the WebBrowser cookie information to HttpWebRequest Build a "cookiecontainer" to keep the cookies in the WebBrowser. Login cookie in WebBrowser saved in WebBrowser.Document.Cookie
Cookiecontainer Mycookiecontainer = new Cookiecontainer (); The cookie of String is to be converted into a cookie type and put into 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.abc.com";//Must be written to
mycookiecontainer.add (CK);
} HttpWebRequest Hreq = (HttpWebRequest) httpwebrequest.create ("http://www.abc.com/search.asp");
Hreq. Method = "POST";
Hreq. ContentType = "application/x-www-form-urlencoded";
Self-created 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 (); |
