Detailed introduction to the method of modifying routing in ThinkPHP

When using ThinkPHP to develop projects, routing is a very important part. Because the routing settings will directly affect the access efficiency and user experience of the project. In order to allow more people to better use ThinkPHP, this article will introduce in detail how to modify ThinkPHP's routing.

1. The concept of routing

Routing refers to the parsing and mapping of URLs, converting URLs into corresponding controllers and methods. Simply put, routing specifies the mapping between the URL that a user accesses from a website or web application and the resource that the URL represents. ThinkPHP's routing is divided into two types: basic routing and annotation routing.

2. Basic routing

Basic routing refers to writing routing rules directly in the Route class of ThinkPHP. The advantage of this method is that it is convenient to use, but the disadvantage is that it easily causes bloated routing files.

1. Configuration of basic routing

The configuration of basic routing is very simple. You only need to write routing rules in the config/route.php file. The code is as follows:

use think\facade\Route;

// 定义路由规则
Route::rule('hello/:name', 'index/hello');

2. Access to basic routing

The way to access basic routing is very simple. You only need to enter the corresponding URL in the address bar to access. For example, the routing rules in the above code can be accessed as follows:

http://localhost/index/hello/name/ThinkPHP

3. Annotation routing

Annotation routing refers to configuring routing rules in the controller through annotations. The advantage of this method is that routing rules are bound to controllers and methods, and the code is clearer and easier to understand, but it requires writing annotations in the controller, which is time-consuming.

1. Annotation routing configuration

When using annotation routing, you need to use the @route annotation in front of the controller class to define routing rules. For example:

<?php

namespace app\index\controller;

/**
 * @route('hello/:name', method='get')
 */
class Index
{
    public function hello($name)
    {
        return 'Hello,' . $name . '!';
    }
}

In the above code, we use the GET request method, and the routing rule is hello/:name.

2. Access to annotation routing

To access annotation routing, you also need to enter the corresponding URL in the address bar. For example, the routing rules in the above code can be accessed as follows:

http://localhost/hello/name/ThinkPHP

4. Modification of routing

When we need to modify the existing routing rules during the development of the project, we can use Modify in the following ways:

1. Modification of basic routing

Modification of basic routing is very simple. You only need to modify the corresponding routing rules in the config/route.php file. . For example, modify the routing rule of hello/:name to hello/:age, the code is as follows:

use think\facade\Route;

// 修改路由规则
Route::rule('hello/:age', 'index/hello');

2. Modification of annotation routing

The modification of annotation routing is also very simple, just add the corresponding Just modify it in the controller. For example, modify the routing rule of the Index controller to newhello/:name, and the code is as follows:

<?php

namespace app\index\controller;

/**
 * @route('newhello/:name', method='get')
 */
class Index
{
    public function hello($name)
    {
        return 'Hello,' . $name . '!';
    }
}

After modifying the routing, you can access it in the corresponding way.

5. Summary

Routing is a problem that we must face and solve when developing Web applications. ThinkPHP's routing is divided into two types: basic routing and annotation routing. We can choose different routing methods according to our own needs. At the same time, we can also enhance the usability and user experience of the application by modifying the routing rules, making our application easier to maintain and expand.
