What does thinkphp routing do?

ThinkPHP is an open source MVC framework based on PHP, which is very popular among developers. Routing is a very important component of the ThinkPHP framework and is one of the core mechanisms for the framework to implement URL access. Especially in the MVC mode, routing plays an even more important role.

So, what does thinkphp routing do?

1. Introduction

When developing a Web application, when a user accesses a specific URL address, the server needs to call the corresponding controller method for processing. In this case, the routing mechanism needs to be used.

Routing in the ThinkPHP framework maps the URL address entered by the user to a specific controller method, and encapsulates this process into a routing class. Developers can flexibly configure routing according to needs.

2. Function

1. Beautify the URL address

By using ThinkPHP routing, developers can beautify the URL address and convert some long and complex URL addresses into Convert difficult and difficult URL addresses into simple and clear URL addresses to improve user experience.

For example: the original URL address is http://localhost/index.php?m=home&c=index&a=login. After using routing, the address can be converted to http://localhost/index/login.

2. Implement SEO optimization

In search engine optimization, some search engines will reduce the processing weight of parameters in the URL and pay more attention to the keywords in the URL. , so using ThinkPHP routing can convert the URL into a more keyword-friendly form, which can improve the search ranking of the website and optimize SEO.

3. Implementing URL security

Since some sensitive information may be returned to the URL address, if the transmission is not encrypted, it will threaten the security of the server. Using ThinkPHP routing to encrypt the URL can improve the security of the URL and protect sensitive information.

4. Achieving cross-platform functionality

In Web application development, the same application needs to be adapted to be accessed by different platforms, so cross-platform adaptation is required. Using ThinkPHP routing, developers can adapt URLs according to the platform to improve cross-platform functionality.

3. Basic usage

In the ThinkPHP framework, the routing mechanism is enabled by default, so developers only need to follow the following steps to configure to implement routing:

1. Modify the configuration file

Find the route.php file in the config directory. After opening, you will see the following default configuration:

return [
    'route'=>[
        'index'=>'index/index',
    ]
];

'index' refers to the suffix of the URL address. , 'index/index' represents the controller and method called. The default here is to call the index method under the Index controller.

2. Configure routing rules

In the route.php file, developers can customize routing rules according to their needs and add the following code:

return [
    'route'=>[
        'login'=>'home/index/login',
        'reg'=>'home/index/register',
    ]
];

The In the code, 'home/index/login' represents the controller and method, and 'login' represents the URL address in the URL.

3. Calling the method

In the view layer (View), when calling the method, you only need to enter the custom routing address:

<a href="<?php echo url('login');?>">登录</a>

4. Access

Enter the custom routing address in the browser to access the corresponding controller method.

4. Notes

1. Routing rules must be standardized

In routing rules, attention must be paid to the correctness of capitalization, slashes, and words.

2. Prevent routing conflicts

When defining different routing rules, you need to pay attention to avoid conflicts between the two rules, otherwise the program will not run normally.

3. Can carry out secondary development on the routing process

Secondary development on the routing process can increase its flexibility and better adapt to the needs of developers.

In short, the ThinkPHP routing mechanism is an important component, which can realize important functions such as URL address beautification, SEO optimization, security guarantee, and cross-platform adaptation. Developers can flexibly use ThinkPHP routing to improve the development efficiency and user experience of web applications.
