What to do if laravel login time expires

Laravel login time failure solution: 1. Cookie session configuration, you can set the "SESSION_LIFETIME" variable in the ".env" file; 2. Extend the session life cycle by refreshing the session every time the user requests Expiration time, or extend the life cycle of the session through custom middleware; 3. Manage user activity time, use JavaScript to send requests regularly to simulate user activities, or require users to re-verify their identities when they perform sensitive operations.

Laravel is a popular PHP development framework for building scalable web applications. In Laravel, user login is a very common function, but sometimes you encounter the problem of invalid login time. When users have been inactive for a period of time, they will be automatically logged out. This is for security and user experience reasons, however, sometimes this automatic logout is not the desired behavior. This article will help you solve the problem of Laravel login time invalidation.

1. Cookie session configuration

In Laravel, sessions are implemented through cookies. In Laravel's configuration file, you can find session-related configuration items. By default, the `lifetime` option is set to 120 minutes, which means the user will be automatically logged out if there is no activity for 120 minutes.

If you wish to change the session life cycle, you can set the `SESSION_LIFETIME` variable in the `.env` file. For example, if you want to set the session lifetime to 30 minutes, you can add `SESSION_LIFETIME=30` to the `.env` file and reconfigure the application configuration cache.

2. Extend the session life cycle

In some cases, you may want to extend the session life cycle so that the user can still Keep me logged in. You can achieve this in two ways.

The first way is by refreshing the session's expiration time every time the user requests it. You can add the following code snippet in your application's base controller:

public function __construct()
{
$this->middleware(function ($request, $next) {
$response = $next($request);
session()->put('last_activity', time());
return $response;
});
}

The above code will store the current time in the `last_activity` key in the session on every request. In this way, the session's expiration time will be reset to the time of the current request, thereby extending the session life cycle.

The second way is to extend the session life cycle through custom middleware. You can create a new middleware in the `app/Http/Middleware` directory, such as `ExtendSessionLifetime`. Add the following code snippet in the `handle` method of the middleware:

public function handle($request, Closure $next)
{
if (auth()->check()) {
session()->put('last_activity', time());
}
return $next($request);
}
然后，在`app/Http/Kernel.php`文件的`$middleware`数组中注册你的中间件：
protected $middleware = [
// ...
\App\Http\Middleware\ExtendSessionLifetime::class,
];

In this way, the middleware will be executed on every request, and if the user is already logged in, the session's expiration time will be reset to the current request time.

3. Manage user activity time

In addition to extending the life cycle of the session, you can also manage user activity time through other methods to avoid unnecessary automatic Sign out.

One approach is to use JavaScript to send requests periodically to simulate user activity. You can create a JavaScript function that will send requests to a specific URL on the server at certain intervals to simulate user activity. The server will receive the request and refresh the user's session expiration time.

Another approach is to require users to re-authenticate when they perform sensitive operations. For example, you can require users to re-enter their password to verify their identity when they perform actions such as paying for an order or changing their password. In this way, even if the session has expired, users will still need to re-authenticate their identities when performing sensitive operations.

Summary

Laravel login time expiration is a common problem, but we can solve this problem by extending the session life cycle and managing user activity time. First, we need to understand the cookie session configuration, and then we can solve the login time expiration problem by setting the session life cycle. Secondly, we can further control how long a user session is valid by refreshing the session expiration time and managing user activity time. Through these methods, we can provide better user experience and security.
