Laravel is a popular PHP development framework, in which issues related to user login timeliness are often an important issue that developers need to focus on and deal with. In actual use, developers need to adjust the login time expiration policy based on actual needs and business scenarios to ensure system security and user experience. This article will share some guidelines on adjusting Laravel's login time expiration policy, while providing specific code examples for reference.

Step 1: Set the login session expiration time

In the Laravel framework, by default, the session expiration time after a user successfully logs in is determined by the 'lifetime' parameter in the session configuration file. The default is 120 minutes. If you want to modify this expiration time, you can modify it in the config/session.php file. For example, set the session expiration time to 30 minutes:

'lifetime' => 30,

In this way, after the user successfully logs in, if there is no operation within 30 minutes, the system will automatically log his account offline from the logged in state, which improves System security.

Step 2: Use the Remember Me function

In some business scenarios, users may want the system to remember their login status to avoid frequent login operations. In order to achieve this function, Laravel provides the Remember Me function. When logging in, the user can choose to check the "Remember Me" option, and the system will set a "remember_token" in the cookie when the user logs in, so that the user can automatically recognize and maintain the logged in status the next time he logs in.

if (Auth::attempt(['email' => $email, 'password' => $password], $remember)) {
    // 記住我功能生效
}

When the user selects "Remember me", the system will save the remember_token in the remember_token field of the users table by default. The system will automatically recognize the token and maintain the logged in status when logging in next time. It should be noted that in order to ensure security, it is recommended to use a more complex encryption method to encrypt the token.

Step 3: Manually set the login expiration time

Sometimes, we want to set the login expiration time according to specific business needs instead of using the default time setting. In this case, we can choose to manually set the login expiration time. For example, when a user performs some sensitive operations, we can manually extend the session time after successful login to ensure that the user will not be forced offline during the operation.

Auth::login($user);
$request->session()->put('key', 'value');
$request->session()->put('last_activity', now());

After the user successfully logs in, we can manually save the login time in the session, and determine whether the login time needs to be updated based on the actual situation during specific operations. For example, when submitting a form, we can determine whether the last activity time is within the specified range. If not, force the user offline or re-login verification.

Summary:

Through the above guide, we can draw some suggestions for adjusting the login time expiration strategy in Laravel, including setting the session expiration time, using the Remember Me function and manually setting the login expiration date. time. Based on specific business needs and security requirements, developers can choose a method suitable for their own projects to make adjustments to improve system security and user experience. Hopefully the guidance provided in this article will be helpful to you when dealing with Laravel login time expiration policies.
