从不同的网站登录，通过URL传递参数

Question

I have question about log-in from different Website.

Is it possible that a user can login from Website A to Website B by passing parameter (username and password) trough URL?

For example, I have login Form (contain username and password field) in Website A, than when user click submit, parameter will pass trough URL, and redirect to Website B (already login)

I have seen an article that allow it, something like

http://mydomain.com/login.php?username=iqbal&password=12345

but i don't know how to use it. Is it safe to use?

Answer 1

as per: Allow php sessions to carry over to subdomains

Here are 3 options.

Place this in your php.ini:

session.cookie_domain = ".example.com"

In your .htaccess:

php_value session.cookie_domain .example.com

As the first thing in your script:

ini_set('session.cookie_domain', '.example.com' );
