What is the method for laravel to define routing

"The origin of the path" is similar to Java mapping. The actual function is to establish a clear direction for the acceptance and processing of data, and the path The origin involves two questions: In what way does the path come from? Where should we go when the path comes? Below we will use several examples to introduce several ways of defining routes.

We first find the project path of laravel, find the folder named routes here, this is where the routes are stored, in this folder we can see the web.php file, here is where we define the route Where

1.GET mode routing

In web.php, there is a route pointing to the root by default, and get is used here. The request is made in the way of route:: is a fixed route declaration format, and then the request method is defined later. There are two parameters in get(), the first is the path, the second is the anonymous method, and the return value is filled in the method.

//根路由Route::get('/', function () {
    return view('welcome');});

Request:

2. POST route

The definition format of post route is the same as get. Both the declaration format and parameter settings are the same, but the request method is different. However, since we do not involve submission operations such as forms, we will not release similar demonstration screenshots.

//post路由Route::post('/post', function () {
     echo 'post请求方式演示';});

3.any route

Any means any, whether it is a get request or a post request, any route can be passed.

//访问根下home1,可选参数传递Route::any('/home1', function () {
    echo '当前是根下home1';});

Demo:

You can also pass parameters

//必选参数传递Route::any('/test1/{id}', function ($id) {
    echo '当前是根用户id' . $id;});

Demo:

4. Match mode routing

match can specify multiple methods for routing. It can support multiple methods like any, but here you need to formulate the request method you need to use. , so it has one more parameter than other routing configurations.

//我们指定post和get方式Route::match(['get','post'],'/home', function () {
    echo '当前是根下home';});

Demo:

5. Routing group

The concept of routing group is similar to ours In the windows file directory, we originally spread a lot of pictures on the desktop. Later, we created a new folder and organized the pictures into it for the convenience of management. However, what is saved here is not the picture but the route.
Multiple routes can be written under the anonymous function of group.

//路由群组Route::group(['prefix'=>'admin'], function () {
	
	Route::any('test1', function () {
   	 echo '路由群组测试';});});

Demonstration:
