【總結】清除webbrowser cookie/session的6種方法
阿新 • • 發佈：2018-11-16
下面是我測試下來的6種清除webbrowser中cookie的6種方法：
往下拉有詳細用法
//方法一：呼叫 wininet.dll清除cookie (推薦) SuppressWininetBehavior(); //方法二：刪除使用者登入後的資訊,這裡相當於瀏覽器的登出功能,使用的是ie自帶的功能 (推薦) HtmlDocument document = wb.Document; document.ExecCommand("ClearAuthenticationCache", false, null); //方法三：刪除本機cookie 此方法會彈出ie清除cookie的彈出框 //Temporary Internet Files （Internet臨時檔案） //RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 8 //Cookies //RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 2 //History (歷史記錄) //RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 1 //Form. Data （表單資料） //RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 16 //Passwords (密碼） //RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 32 //Delete All （全部刪除） //ShellExecute(IntPtr.Zero, "open", "rundll32.exe", " InetCpl.cpl,ClearMyTracksByProcess 2", "", ShowCommands.SW_HIDE); ShellExecute(IntPtr.Zero, "open", "rundll32.exe", " InetCpl.cpl,ClearMyTracksByProcess 255", "", ShowCommands.SW_HIDE); //方法四:使用webbrowser自帶的清coookie的方法 (不推薦，清不掉session，實測無效) wb.Document.Cookie.Remove(0, (wb.Document.Cookie.Count() - 1)); //方法五：使用js清除cookie (不推薦，清不掉session) wb.Navigate("javascript:void((function(){var a,b,c,e,f;f=0;a=document.cookie.split('; ');for(e=0;e<a.length&&a[e];e++){f++;for(b ='.' +location.host;b;b=b.replace(/^(?:%5C.|[^%5C.]+)/,'')){for(c =location.pathname;c;c =c.replace(/.$/,'')){document.cookie =(a[e]+'; domain='+b+' ; path='+c+' ; expires='+new Date((new Date()).getTime()-1e11).toGMTString());}}}})())"); //var a,b,c,e,f; //f=0; //a=document.cookie.split(' ; '); //b='.'+'baidu.com'; ////b='.'+'www.baidu.com'; //for(e=0;e<a.length;e++){ // //b='.'+location.host; // b=b.replace(/^(?:%5C.|[^%5C.]+)/,''); // c=location.pathname; // c=c.replace(/.$/,''); // ck = a[e]+'; domain='+b+'; path='+c+'; expires='+new Date((new Date()).getTime()-1e11).toGMTString(); // console.log(ck); // document.cookie=ck; //} //方法六：使用InternetSetCookie給cookie賦null值 (不推薦) //也可以給此Cookie賦空值:InternetSetCookie //InternetSetCookie("http://.qq.com/", NULL, "uin=; PATH=/; DOMAIN=qq.com");
方法一：
[System.Runtime.InteropServices.DllImport("wininet.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto, SetLastError = true)] public static extern bool InternetSetOption(int hInternet, int dwOption, IntPtr lpBuffer, int dwBufferLength); /// <summary> /// 使用InternetSetOption操作wininet.dll清除webbrowser裡的cookie /// </summary> private static unsafe void SuppressWininetBehavior() { /* SOURCE: http://msdn.microsoft.com/en-us/library/windows/desktop/aa385328%28v=vs.85%29.aspx * INTERNET_OPTION_SUPPRESS_BEHAVIOR (81): * A general purpose option that is used to suppress behaviors on a process-wide basis. * The lpBuffer parameter of the function must be a pointer to a DWORD containing the specific behavior to suppress. * This option cannot be queried with InternetQueryOption. * * INTERNET_SUPPRESS_COOKIE_PERSIST (3): * Suppresses the persistence of cookies, even if the server has specified them as persistent. * Version: Requires Internet Explorer 8.0 or later. */ int option = (int)3/* INTERNET_SUPPRESS_COOKIE_PERSIST*/; int* optionPtr = &option; bool success = InternetSetOption(0, 81/*INTERNET_OPTION_SUPPRESS_BEHAVIOR*/, new IntPtr(optionPtr), sizeof(int)); if (!success) { MessageBox.Show("Something went wrong ! Clear Cookie Failed!"); } }
方法二：
就只有這一句就好了：
//方法二：刪除使用者登入後的資訊,這裡相當於瀏覽器的登出功能,使用的是ie自帶的功能 (推薦)
HtmlDocument document = wb.Document;
document.ExecCommand("ClearAuthenticationCache", false, null);方法三：
//方法三：刪除本機cookie 此方法會彈出ie清除cookie的彈出框 //Temporary Internet Files （Internet臨時檔案） //RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 8 //Cookies //RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 2 //History (歷史記錄) //RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 1 //Form. Data （表單資料） //RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 16 //Passwords (密碼） //RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 32 //Delete All （全部刪除） //ShellExecute(IntPtr.Zero, "open", "rundll32.exe", " InetCpl.cpl,ClearMyTracksByProcess 2", "", ShowCommands.SW_HIDE); ShellExecute(IntPtr.Zero, "open", "rundll32.exe", " InetCpl.cpl,ClearMyTracksByProcess 255", "", ShowCommands.SW_HIDE);
ShellExecute方法：public enum ShowCommands : int
{
SW_HIDE = 0,
SW_SHOWNORMAL = 1,
SW_NORMAL = 1,
SW_SHOWMINIMIZED = 2,
SW_SHOWMAXIMIZED = 3,
SW_MAXIMIZE = 3,
SW_SHOWNOACTIVATE = 4,
SW_SHOW = 5,
SW_MINIMIZE = 6,
SW_SHOWMINNOACTIVE = 7,
SW_SHOWNA = 8,
SW_RESTORE = 9,
SW_SHOWDEFAULT = 10,
SW_FORCEMINIMIZE = 11,
SW_MAX = 11
}
[DllImport("shell32.dll")]
static extern IntPtr ShellExecute(IntPtr hwnd, string lpOperation, string lpFile, string lpParameters, string lpDirectory, ShowCommands nShowCmd);方法四：
//方法四:使用webbrowser自帶的清coookie的方法 (不推薦，清不掉session，實測無效)
wb.Document.Cookie.Remove(0, (wb.Document.Cookie.Count() - 1));方法五：
//方法五：使用js清除cookie (不推薦，清不掉session)
wb.Navigate("javascript:void((function(){var a,b,c,e,f;f=0;a=document.cookie.split('; ');for(e=0;e<a.length&&a[e];e++){f++;for(b ='.' +location.host;b;b=b.replace(/^(?:%5C.|[^%5C.]+)/,'')){for(c =location.pathname;c;c =c.replace(/.$/,'')){document.cookie =(a[e]+'; domain='+b+' ; path='+c+' ; expires='+new Date((new Date()).getTime()-1e11).toGMTString());}}}})())");
//var a,b,c,e,f;
//f=0;
//a=document.cookie.split(' ; ');
//b='.'+'baidu.com';
////b='.'+'www.baidu.com';
//for(e=0;e<a.length;e++){
// //b='.'+location.host;
// b=b.replace(/^(?:%5C.|[^%5C.]+)/,'');
// c=location.pathname;
// c=c.replace(/.$/,'');
// ck = a[e]+'; domain='+b+'; path='+c+'; expires='+new Date((new Date()).getTime()-1e11).toGMTString();
// console.log(ck);
// document.cookie=ck;
//}將 wb.Navigate("javascript:void((function(){。。。}裡的內容換成下面註釋掉的程式碼，寫好你要清cookier 的domain然後就可以清了，但清不掉session，這個是從外國網站上看來的，實際無效！
方法六：
//方法六：使用InternetSetCookie給cookie賦null值 (不推薦)
//也可以給此Cookie賦空值:InternetSetCookie
//InternetSetCookie("http://.qq.com/", NULL, "uin=; PATH=/; DOMAIN=qq.com");關於InternetSetCookie這個方法自己網上搜索一下.
