网上收集的WebBrowser的Cookie操作

转自:http://xcily1.blog.163.com/blog/static/287169162008975834286/

1、WebBrowser设置Cookie

 1 public   partial   class  WebBrowserControl : Form
 2 <img none';="" document.getelementbyid('codehighlighter1_50_596_open_text').style.display="none" ;="" document.getelementbyid('codehighlighter1_50_596_closed_image').style.display="inline" document.getelementbyid('codehighlighter1_50_596_closed_text').style.display="inline" ;"="" alt="" src="http://www.cnblogs.com/Images/OutliningIndicators/ExpandedBlockStart.gif" align="top" style="border: 0px; max-width: 100%;">     {
 3          private  String url;
 4
 5         [DllImport( " wininet.dll " , CharSet  =  CharSet.Auto, SetLastError  =   true )]
 6          public   static   extern   bool  InternetSetCookie( string  lpszUrlName,  string  lbszCookieName,  string  lpszCookieData);
 7
 8          public  WebBrowserControl(String path)
 9 <img none';="" document.getelementbyid('codehighlighter1_335_582_open_text').style.display="none" ;="" document.getelementbyid('codehighlighter1_335_582_closed_image').style.display="inline" document.getelementbyid('codehighlighter1_335_582_closed_text').style.display="inline" ;"="" alt="" src="http://www.cnblogs.com/Images/OutliningIndicators/ExpandedSubBlockStart.gif" align="top" style="border: 0px; max-width: 100%;">         {
10              this .url  =  path;
11             InitializeComponent();
12
13              //  set cookie
14             InternetSetCookie(url,  " JSESSIONID " , Globals.ThisDocument.sessionID);
15
16              //  navigate
17             webBrowser.Navigate(url);
18         }
19         
20 }

 2、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      

 1           CookieContainer myCookieContainer  =   new  CookieContainer();
 2
 3
 4              // String 的Cookie　要转成　Cookie型的　并放入CookieContainer中
 5              string  cookieStr  =  webBrowser1.Document.Cookie;
 6              string [] cookstr  =  cookieStr.Split( ' ; ' );
 7              foreach  ( string  str  in  cookstr)
 8 <img none';="" document.getelementbyid('codehighlighter1_302_584_open_text').style.display="none" ;="" document.getelementbyid('codehighlighter1_302_584_closed_image').style.display="inline" document.getelementbyid('codehighlighter1_302_584_closed_text').style.display="inline" ;"="" alt="" src="http://www.cnblogs.com/Images/OutliningIndicators/ExpandedBlockStart.gif" align="top" style="border: 0px; max-width: 100%;">             {
 9                  string [] cookieNameValue  =  str.Split( ' = ' );
10                 Cookie ck  =   new  Cookie(cookieNameValue[ 0 ].Trim().ToString(), cookieNameValue[ 1 ].Trim().ToString());
11                 ck.Domain  =   " www.abc.com " ; // 必须写对
12                 myCookieContainer.Add(ck);
13             }
14
15             HttpWebRequest hreq  =  (HttpWebRequest)HttpWebRequest.Create( " http://www.abc.com/search.asp " );
16             hreq.Method  =   " POST " ;
17             hreq.ContentType  =   " application/x-www-form-urlencoded " ;
18          
19              // 自己创建的CookieContainer
20             hreq.CookieContainer  =  myCookieContainer;
21          
22              string  postdata  =   " id=2005&action=search&name= " ;
23              byte [] byte1  =  Encoding.ASCII.GetBytes(postdata);
24             hreq.ContentLength  =  byte1.Length;
25           
26             Stream poststream  =  hreq.GetRequestStream();
27             poststream.Write(byte1,  0 , byte1.Length);
28             poststream.Close();
29       
30             HttpWebResponse hres  =  (HttpWebResponse)hreq.GetResponse();
