What are the types of routing in ThinkPHP6? how to use?

ThinkPHP6 is an open source framework based on PHP that provides very powerful and flexible routing functions to support multiple types of routing. In this article, we will discuss the different kinds of routing available in ThinkPHP6 and their usage.

1. Routing based on URL pattern

This is the most basic routing type in ThinkPHP6, which performs route matching based on URL pattern and parameter matching. In this routing type, each parameter in the URL represents a method name or parameter of a controller class. For example:

Route::rule('/index/:id', 'index/index/index');

In the above code, the routing rule first defines a URL pattern and uses a colon to specify a parameter: id. This parameter will match the method index in the controller class Index and provide a parameter named id.

2. RESTful routing

RESTful routing is an HTTP verb based routing that can be used with RESTful APIs. This type of routing allows you to handle multiple HTTP request types (such as GET, POST, PUT, DELETE, etc.) under the same URL. For example:

Route::rule('/user/:id', 'user', 'GET|DELETE|PUT');

In this routing rule, we use the route() function to define a route named user and specify the allowed HTTP verbs: GET, DELETE, and PUT.

3. Route grouping

The route grouping function in ThinkPHP6 allows you to organize and manage related routes. For example, you can define a common prefix within a set of routes to better organize your application's routes. For example:

Route::group('/admin', function () {
    Route::rule('/index/:id', 'admin/index/index');
    Route::rule(':controller/:action', 'admin/:controller/:action');
});

In the above code, we first define the routing group/admin and define two routing rules in it. The first rule will match the /admin/index/:id route and the second rule will match the /admin/:controller/:action route. Note that in the second rule, the controller and action names are represented by the placeholders :controller and :action.

4. Dynamic routing

Dynamic routing allows you to use regular expressions in routing rules. This allows you to specify more complex routing rules for greater control over matching. For example:

Route::rule(':year/:month/:day', 'news/date', ['method' => 'get'], ['year' => 'd{4}', 'month' => 'd{2}', 'day' => 'd{2}']);

In this routing rule, we define three placeholders: year, :month, and :day, and use regular expressions to restrict the format of each parameter.

5. Route Cache

Route cache is a very useful feature that can help you improve the performance of your application. Route caching can speed up route resolution for your application by allowing you to cache resolved route rules. To enable route caching, set the following option in the application configuration file config:

// 开启路由缓存
'route_cache' => true,

In this setup, we set the option route_cache to true to allow caching of resolved route rules.
