How to set up routing in Flight framework?

With the increasing number of web applications, web development frameworks have become an important part of modern web application development. Today we are going to introduce a popular web framework - Flight, and how to set up routing in Flight.

Flight is a minimalist web framework optimized for small web applications and JSON APIs. It is characterized by being lightweight, easy to learn and use, and has no cumbersome configuration files. It provides basic routing functionality that can make your code structure clearer and better organized.

In Flight, routing refers to the process of mapping URLs to specific handlers. A router is a central controller that handles the routing of HTTP requests. Routing uses a combination of HTTP methods, URLs, and handlers to provide a simple yet effective access mechanism for web applications.

Below we will introduce how to configure routing in Flight with examples.

First, we need to know that a handler can be a function or method. The general method of defining routes in Flight is:

Flight::route($method, $route, $callback)

where $method is the HTTP method (GET, POST, PUT, DELETE), $route is the URL path (starting relative to your application root path ), $callback is the processing function or method.

For example, if we need to define a route that responds to a GET request, we can write a handler as follows:

Flight::route('GET /hello', function(){
    echo 'Hello, world!';
});

This will define a route that responds to a GET request for the /hello URL and prints Output "Hello, world!".

You can use abstract route definition classes to simplify route definition. For example, an example of defining a controller class named "UserController" and using it to handle user-related routing is as follows:

class UserController {
 
  public static function register() {
    // some registration logic here
  }
}

Flight::route('GET /user/register', ['UserController', 'register']);

The above example shows how to bind routing that handles logic to UserController The register method, no matter which method, can implement routing forwarding, that is, handing the URL request to the matching handler for processing.

In addition to basic routing settings, Flight also provides the following more advanced routing functions:

1. Routing with parameters

In Flight, You can define route parameters by using placeholders in the URL. For example:

Flight::route('GET /user/@id', function($id){
    echo 'User ID: ' . $id;
});

When requesting /user/123, the $id variable will contain 123.

2. Routing with regular expressions

If you need to validate specific route parameters, you can use regular expressions. For example:

Flight::route('GET /user/@id:[0-9]+', function($id){
    echo 'User ID: ' . $id;
});

In this example, the route will only match the id parameter consisting of numbers.

3. Route Grouping

Route Grouping is an efficient way to group multiple routes together and share some of the same functionality or Attributes. In Flight, you can define routing groups by using the group() method. For example:

Flight::route('/user', function(){
    Flight::render('user/list', array('users' => $users));
});

Flight::route('/user/@id', function($id){
    $user = User::find($id);
    Flight::render('user/view', array('user' => $user));
});

Flight::route('/user/create', function(){
    Flight::render('user/create');
});

//定义分组
Flight::group('/admin', function(){
    Flight::route('/user', function(){
        $users = User::getAll();
        Flight::render('admin/user/list', array('users' => $users));
    });

    Flight::route('/user/create', function(){
        Flight::render('admin/user/create');
    });
});

In the above example, we first define a set of routes for the /user URL prefix, and then we define a route for the /admin URL prefix for user administrator-related operations. Within this group, we define two new routes that depend on other routes within the group and dependency injection.

The Flight framework provides an efficient way to quickly respond to web requests. Using concise syntax and powerful functionality, Flight enables web developers to quickly and easily implement tedious tasks such as route management and request handling.
