ThinkPHP6 routing analysis detailed explanation: in-depth understanding of routing principles

Introduction:
In web application development, routing is a very important concept. It is responsible for parsing the user's requests and dispatching them to the corresponding controllers and actions. In the ThinkPHP6 framework, the routing system is designed to be very flexible and powerful. This article will deeply explore the principles and usage of ThinkPHP6 routing parsing, and illustrate it through code examples.

1. Basic configuration of ThinkPHP6 routing
To use the routing function of ThinkPHP6, you first need to make the corresponding settings in the application's routing configuration file. Open the route.php file in the route directory, and you can see the following default routing configuration:

use thinkacadeRoute;

Route::get('hello/:name', 'index/hello');

In the default routing configuration, we created a GET request , it will match URLs starting with hello and dispatch the request to the hello action of the index controller. The :name part represents a parameter, which can be obtained through the $name variable in the action.

2. ThinkPHP6 route parsing principle
In the controller, we can use the parameters parsed by the route through dependency injection. In the ThinkPHP6 framework, the thinkRequest class is responsible for parsing routes and saving the parsing results in the thinkRequest object. We can access this object through request()global function.

The following is a simple example that shows how to get the parameters parsed by the route in the controller:

namespace appindexcontroller;

use thinkRequest;

class Index
{
    public function hello(Request $req)
    {
        $name = $req->param('name');
        return 'Hello, '.$name.'!';
    }
}

In this example, we use through dependency injection thinkRequest class, and then obtain the parameters parsed by the route through the param() method.

3. Advanced usage of ThinkPHP6 routing
In addition to basic route analysis, ThinkPHP6 also provides some advanced routing usage to meet more complex routing requirements.

1. Routing group
   Routing group is a way to group and manage multiple routing rules. For example, we can create a routing group to manage the routing rules of the backend management system:

use thinkacadeRoute;

Route::group('admin', function () {
    Route::get('index', 'admin/index');
    Route::get('user', 'admin/user');
});

In the above code, admin/index and admin/user Is the routing rule relative to the admin prefix. When accessing these routes, you can directly use the corresponding URLs, such as /admin/index and /admin/user.

2. RESTful style routing
   RESTful style routing is a more concise and standardized routing method. In ThinkPHP6, we can quickly define a RESTful-style routing rule with one line of code:

use thinkacadeRoute;

Route::resource('article', 'index/article');

The above code defines a resource route, which will match index based on different requests. /articleIn different actions of the controller, operations such as adding, deleting, modifying, and checking are implemented.

3. Routing parameter restriction
   The routing parameter restriction function can limit the value range of routing parameters. For example, we can restrict the parameters in a routing rule to be numbers, otherwise the match will fail:

use thinkacadeRoute;

Route::get('news/:id', 'index/news')->pattern(['id' => 'd+']);

In the above code, :id is a parameter, which must satisfy the regular rules The expression d can match successfully.

4. ThinkPHP6 route cache
In order to improve system performance, ThinkPHP6 provides a route cache function. When we turn on route caching, routing rules will be compiled into PHP files and saved in the cache, which greatly speeds up route parsing.

To enable the route cache function, just make the corresponding settings in the app.php file in the config directory of the application's configuration file. Find the route_cache configuration item and set it to true to enable route caching.

'route_cache' => true,

5. Summary
This article introduces the basic principles and usage of ThinkPHP6 route parsing, and illustrates it through code examples. In actual development, mastering the use of routing can improve the maintainability and performance of the program. I hope that readers will have a deeper understanding of ThinkPHP6 routing through studying this article and be able to flexibly apply it in practice.
