Optimize Laravel login time expiration policy to improve system security
Mar 06, 2024 pm 01:06 PMTitle: Optimizing Laravel login time expiration policy and improving system security
In web development, the user login function is one of the basic functions. In order to ensure the security of the system, the login time expiration policy is particularly important. When developing using the Laravel framework, we can further improve the security of the system by optimizing the login time expiration policy. This article will introduce how to optimize the login time expiration strategy in Laravel and provide specific code examples.
1. Default login expiration time setting
In Laravel, user login status will be maintained for 2 weeks by default (1209600 seconds). This means that after logging in, users can stay logged in for 2 weeks without re-entering their username and password. However, for some sensitive operations or systems with high security requirements, this default setting may not be secure enough. Therefore, we can set a shorter login expiration time by modifying the configuration file.
2. Set the login expiration time
Open the configsession.php
configuration file, find the lifetime
parameter in the file, and modify its value to ours The required login expiration time. For example, we set the login expiration time to 1 hour (3600 seconds):
'lifetime' => 3600,
3. Active logout
In addition to setting a shorter login expiration time, we can also actively log out ways to improve system security. For example, when a user performs some sensitive operations, we can proactively ask the user to log out and require them to re-enter their user name and password.
In Laravel, we can use the following code to actively log out the user login status:
Auth::logout();
4. Use single sign-on
In order to strengthen the security of the system, we also Consider using a single sign-on mechanism. With single sign-on, users only need to log in once and can use it in multiple related systems without having to log in repeatedly. This can reduce the number of users forgetting to log out and improve the security of the system.
You can use Passport
in Laravel to achieve single sign-on. First install the Passport package:
composer require laravel/passport
Then run the php artisan passport:install
command to install Passport. Finally, register the Passport route in AuthServiceProvider
:
use LaravelPassportPassport; Passport::routes();
5. Custom login failure processing
Sometimes, the system may need to perform some custom processing of login failure , such as jumping to a specific page or recording a log. In Laravel, we can achieve this function through custom middleware.
First, create a middleware named CustomSessionTimeoutRedirect
:
php artisan make:middleware CustomSessionTimeoutRedirect
Then, implement custom processing in the handle
method of the middleware Logic:
public function handle($request, Closure $next) { if (Auth::check() && time() - strtotime(auth()->user()->updated_at) > config('session.lifetime')) { Auth::logout(); return redirect()->route('login')->with('session_timeout', '登錄已失效,請重新登錄'); } return $next($request); }
Finally, register the middleware in Kernel.php
, which can be used in global middleware or routing middleware:
'custom.session.timeout' => AppHttpMiddlewareCustomSessionTimeoutRedirect::class,
Conclusion
By optimizing the login time expiration policy, we can further improve the security of the system. In this article, we explain how to set a shorter login expiration time, proactively log out, use single sign-on, and customize login expiration handling. It is hoped that these methods can help developers improve system security and protect users' account information.

This article aims to resolve common errors in the Laravel framework where routing parameter passing matches controller methods. We will explain in detail why writing parameters directly to the controller method name in the routing definition will result in an error of "the method does not exist", and provide the correct routing definition syntax to ensure that the controller can correctly receive and process routing parameters. In addition, the article will explore best practices for using HTTPDELETE methods in deletion operations.

This article aims to solve how to efficiently and securely access deep properties associated with model through string paths when dynamically rendering data in LaravelLivewire components. When you need to obtain specific fields of the associated model based on a configuration string (such as "user.name"), access using object properties will fail. The article will introduce Laravel's data_get helper function in detail and provide code examples to show how to use it to solve this problem gracefully and ensure the flexibility and robustness of data acquisition.

When choosing a suitable PHP framework, you need to consider comprehensively according to project needs: Laravel is suitable for rapid development and provides EloquentORM and Blade template engines, which are convenient for database operation and dynamic form rendering; Symfony is more flexible and suitable for complex systems; CodeIgniter is lightweight and suitable for simple applications with high performance requirements. 2. To ensure the accuracy of AI models, we need to start with high-quality data training, reasonable selection of evaluation indicators (such as accuracy, recall, F1 value), regular performance evaluation and model tuning, and ensure code quality through unit testing and integration testing, while continuously monitoring the input data to prevent data drift. 3. Many measures are required to protect user privacy: encrypt and store sensitive data (such as AES

There are three main ways to set environment variables in PHP: 1. Global configuration through php.ini; 2. Passed through a web server (such as SetEnv of Apache or fastcgi_param of Nginx); 3. Use putenv() function in PHP scripts. Among them, php.ini is suitable for global and infrequently changing configurations, web server configuration is suitable for scenarios that need to be isolated, and putenv() is suitable for temporary variables. Persistence policies include configuration files (such as php.ini or web server configuration), .env files are loaded with dotenv library, and dynamic injection of variables in CI/CD processes. Security management sensitive information should be avoided hard-coded, and it is recommended to use.en

To enable PHP containers to support automatic construction, the core lies in configuring the continuous integration (CI) process. 1. Use Dockerfile to define the PHP environment, including basic image, extension installation, dependency management and permission settings; 2. Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction

This article deeply explores the correct transmission of routing parameters and the matching mechanism of controller methods in the Laravel framework. In response to the common "method does not exist" error caused by writing routing parameters directly to the controller method name, the article elaborates on the correct way to define routing, that is, declare parameters in the URI and receive them as independent parameters in the controller method. At the same time, the article also provides code examples and suggestions on best practices for HTTP methods, aiming to help developers build more robust and RESTful Laravel applications.

This article discusses the correct posture of parameter transfer of controller method in Laravel routing in depth. In response to common errors caused by writing routing parameters directly to the controller method name, the correct routing definition syntax is explained in detail, and the mechanism of Laravel automatic parameter binding is emphasized. At the same time, the article recommends using HTTPDELETE method that is more in line with RESTful specifications to handle deletion operations to improve the maintainability and semantics of the application.
