Form Verification to store the cookie into the user name and password

Some verification modules are inevitable for website development. Many modules often have the option "Remember user name and password.

In. net, you can use a class in the system framework to verify the cookie storage value of the user name and password.

Of course, this process is encrypted. The following code is a simple example.

 

1. Create a mycookie. CS file:

 

Namespace cookies
{
Public class mycookies
{
Public static httpcookie sendcookie (string name, string PWD)
{
// Create a ticket instance
Formsauthenticationticket ticket = new formsauthenticationticket (1, "ansen", datetime. Now, datetime. Now. adddays (1), true, "userrole ","/");
// Create an encrypted cookie authentication ticket
String hashticket = formsauthentication. Encrypt (ticket );
Httpcookie cookie = new httpcookie (formsauthentication. formscookiename, hashticket );
Cookie. Values ["name"] = Name;
String md5pass = system. Web. Security. formsauthentication. hashpasswordforstoringinconfigfile (PWD, "MD5 ");
Cookie. Values ["password"] = md5pass;
Cookie. expires = datetime. Now. adddays (1 );
Return cookie;
}
}
}

 

2. Call on the home page:

Namespace cookies
{
Public partial class _ default: system. Web. UI. Page
{
Protected void page_load (Object sender, eventargs E)
{

If (! Ispostback)
{
Initpage ();
}
}
Protected void initpage ()
{
If (session ["ansen"]! = NULL)
{
Response. Write ("the user has logged on! ");
}
Else if (request. Cookies [formsauthentication. formscookiename]! = NULL)
{
String name = request. Cookies [formsauthentication. formscookiename] ["name"]. tostring ();
String Pwd = request. Cookies [formsauthentication. formscookiename] ["password"]. tostring ();
If (Pwd = (system. Web. Security. formsauthentication. hashpasswordforstoringinconfigfile ("123456", "MD5 ")))
{
Session ["ansen"] = Name;
Response. Write ("the user logs on from the cookie! ");
Txtname. Text = Name;
Txtpwd. Text = PWD;
}
}
Else
{
Response. Write ("not logged on! ");
}

}
Protected void btnsumbit_click (Object sender, eventargs E)
{
If (txtname. Text = "ansen" & txtpwd. Text = "123456 ")
{
Session ["ansen"] = txtname. text;
Response. Cookies. Add (mycookies. sendcookie (txtname. Text, txtpwd. Text ));
Response. Write ("User Logon successful! ");
}
Else
{
Response. Write ("User Logon Failed! ");
}
}
Protected void btnsignout_click (Object sender, eventargs E)
{
If (request. Cookies [formsauthentication. formscookiename]! = NULL)
{
Response. Cookies. Clear ();
Formsauthentication. signout ();
}
If (session ["ansen"]! = NULL)
{
Session. Abandon ();
}
Response. Redirect ("default. aspx ");
}
Protected void btnsession_click (Object sender, eventargs E)
{
If (session ["ansen"]! = NULL)
{
Session. Abandon ();
}
}
}
}

Default username and password: ansen/123456
