How to set up a router with thinkphp

May 26, 2023 am 09:19 AM

With the popularity of the Internet, website development has attracted more and more public attention. In website development, router is a very important concept. The role of the router is to distribute different requests to different handlers based on different URL addresses. ThinkPHP is an open source PHP framework with strong controller and router functions, which allows us to complete website development more conveniently.

So, how to set up the router in ThinkPHP? In this article, we will introduce the basic knowledge and setup method of ThinkPHP router.

1. What is a router?

In web development, router is a very important concept. Simply put, a router is a controller used to forward requests. It forwards requests to different handlers based on different URLs. For example, a request from the client:

http://www.example.com/user/profile/1

where /user/profile/1 is the URL. Then the router will parse the URL and convert it into the corresponding controller name, method name and parameters, and finally call the specified handler.

2. Basic usage of ThinkPHP router

In ThinkPHP, the router has two modes: PathInfo mode and URL mode. PathInfo mode is the default mode, which uses a URL similar to the following:

http://www.example.com/index.php/user/profile/id/1

where index .php is the entry file, user is the controller name, profile is the method name, id is the parameter name, and 1 is the parameter value. In PathInfo mode, the router parses the URL and converts it into the corresponding controller name, method name and parameters, and finally calls the specified handler.

The URL pattern uses a URL similar to the following:

http://www.example.com/index.php?m=user&a=profile&id=1

Where, m represents the module name, a represents the method name, id is the parameter name, and 1 is the parameter value. In URL mode, the router parses the URL and converts it into the corresponding controller name, method name and parameters, and finally calls the specified handler.

3. Router setting method

In the ThinkPHP framework, the router setting method is relatively simple. We only need to set it in the applicationconfig.php configuration file.

The following is a basic router setting example:

//开启路由
'URL_ROUTER_ON'   => true, 

//路由规则
'URL_ROUTE_RULES'=>array(
    //路由规则1
    'user/:id'=>'user/profile',
    //路由规则2
    'blog/:year/:month/:day'=>'blog/archive',
),
Copy after login

In the above example, we enabled routing and set up two routing rules. The first rule indicates that when /user/1 is accessed, the router will resolve it to the profile method of the user controller and set the id parameter to 1. The second rule indicates that when /blog/2020/05/31 is accessed, the router will parse it into the archive method of the blog controller and set the year parameter to 2020, the month parameter to 05, and the day parameter to 31.

It should be noted that router rules have priorities. It is recommended to configure rules with high priority first.

4. Advanced usage of routers

In addition to basic router settings, ThinkPHP also provides many advanced router settings, such as router grouping, dynamic router, etc. Here’s a brief introduction to how to use these advanced router settings.

1. Router grouping

Router grouping is to divide routers into multiple groups, and each group has its own routing rules. The following is an example of a router group:

//开启路由
'URL_ROUTER_ON'   => true, 

//路由规则
'URL_ROUTE_RULES'=>array(
    '[user]'     => array('User/'), 
    '[blog]'     => array('Blog/'),
),
Copy after login

In the above example, we set up two router groups: user and blog. Each group has its own routing rules.

2. Dynamic router

Dynamic router means that the router rules can dynamically change according to different requests, such as displaying different pages according to different languages. The following is an example of a dynamic router:

//开启路由
'URL_ROUTER_ON'   => true, 

//路由规则
'URL_ROUTE_RULES'=>array(
    ':lang/blog/:year/:month/:day'=>'blog/archive',
),
Copy after login

In the above example, we set up a dynamic router rule. When the requested URL contains the lang parameter, the router will dynamically parse the router rules based on the lang parameter.

To sum up, router is a very important concept in web development. ThinkPHP provides powerful router functions, which can greatly simplify our development work. In the process of using the router, we need to configure and adjust it according to our own needs in order to achieve more flexible and efficient website development.
