laravel5 的中间件的使用 (1)
1.创建中间件
php artisan make:middleware _Name_Middleware
2.注册中间件
2.1 中间件注册在 Kennel.php 里面
2.2 默认的存放在此处,会自动调用
/** * The application's global HTTP middleware stack. * * These middleware are run during every request to your application. * * @var array */protected $middleware = [ \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class, #可在此处进行注册 如<br />
'App\Http\Middleware\AfterMiddleware',
<br />];
2.3 还有一种触发的方式,就是 从Route进行触发的
2.3.1 首先需要注册他,即
/** * The application's route middleware. * * These middleware may be assigned to groups or used individually. * * @var array */ protected $routeMiddleware = [ 'auth' => \App\Http\Middleware\Authenticate::class, 'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class, 'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class, 'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class, #注册一个 中间件 'demo.before' => 'App\Http\Middleware\BeforeMiddleware', ];
他的使用和默认的有所不同,他想要在 router.php 中 使用 Router:: 的时候触发
<?phpRoute::group(['middleware' => ['web']], function () { Route::get('/', function () { return view('welcome'); }); Route::group(['prefix' => 'demo'],function(){
Route::get('after', ['as'=>'home.after.ware' , 'uses' => 'HomeController@after']);
}); });
此处的代码是这样子的,当我们 访问的时候,他便会 进行自动使用中间件
3. 主要说说第二种方式的触发,可以看到
Kernel.php 处的 middleware 的 demo.before
'demo.before' => 'App\Http\Middleware\BeforeMiddleware',<br /><br /><br />与 Router.php 处的 路由 demo --> before 对应
Route::group(['prefix' => 'demo'],function(){<br /> Route::get('before', ['as'=>'home.before.ware' , 'uses' => 'HomeController@before']);<br />});
OK,写的不好之处,往指正

Setting session cookie parameters in PHP can be achieved through the session_set_cookie_params() function. 1) Use this function to set parameters, such as expiration time, path, domain name, security flag, etc.; 2) Call session_start() to make the parameters take effect; 3) Dynamically adjust parameters according to needs, such as user login status; 4) Pay attention to setting secure and httponly flags to improve security.

The main purpose of using sessions in PHP is to maintain the status of the user between different pages. 1) The session is started through the session_start() function, creating a unique session ID and storing it in the user cookie. 2) Session data is saved on the server, allowing data to be passed between different requests, such as login status and shopping cart content.

How to share a session between subdomains? Implemented by setting session cookies for common domain names. 1. Set the domain of the session cookie to .example.com on the server side. 2. Choose the appropriate session storage method, such as memory, database or distributed cache. 3. Pass the session ID through cookies, and the server retrieves and updates the session data based on the ID.

HTTPS significantly improves the security of sessions by encrypting data transmission, preventing man-in-the-middle attacks and providing authentication. 1) Encrypted data transmission: HTTPS uses SSL/TLS protocol to encrypt data to ensure that the data is not stolen or tampered during transmission. 2) Prevent man-in-the-middle attacks: Through the SSL/TLS handshake process, the client verifies the server certificate to ensure the connection legitimacy. 3) Provide authentication: HTTPS ensures that the connection is a legitimate server and protects data integrity and confidentiality.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
