How to modify the default route in laravel

Laravel is a popular PHP framework that is used by more and more developers due to its simplicity, efficiency, and ease of use. In the Laravel framework, routing is a very important concept. Routing can realize the mapping between URLs and controllers, thereby realizing the functions of web applications. In the Laravel framework, there are many default routes, but these routes are not necessarily suitable for our project, so we need to modify the default routes. This article will introduce you to how to modify the default route in the Laravel framework.

1. Understand the routing concept of the Laravel framework

In the Laravel framework, routing refers to the mechanism that forwards a URL request to the corresponding controller method for processing. Laravel's routing rules are usually defined in the routes/web.php file. The Laravel framework provides an easy-to-use routing system, which includes several commonly used HTTP request methods, such as: GET, POST, PUT, DELETE, etc. For each HTTP request method, Laravel provides corresponding response processing methods, such as: view, json, redirect, etc.

In the Laravel framework, routing usually consists of two parts: URI and callback function. URI refers to the URL used when accessing the route, and the callback function is the operation performed when accessing the corresponding route. If you want to design a new route, you first need to define the URI, and then specify the controller and method to handle the request.

2. How to modify the default route in the Laravel framework

1. Create a custom route

The Laravel framework provides several routes by default, such as: GET, POST, PUT, DELETE, etc., these are defined for different HTTP request methods. If we want to modify the default route, we first need to create a custom route.

Create a new file named routes/custom.php. This file is used to define your own routing rules, and then introduce the file into routes/web.php, as shown in the following code:

//routes/custom.php
Route::get('/custom', 'CustomController@index');

//routes/web.php
require_once __DIR__.'/custom.php';

In the above code, we define a custom route/custom, which will call the index() method of CustomController for processing.

2. Modify Laravel default routing

If we want to modify the default routing of Laravel framework, we need to first understand the definition and rules of default routing. In the Laravel framework, some default routes are defined in the app/Providers/RouteServiceProvider.php file. In this file, we can see a large number of route definitions, such as: /login, /register, etc.

If we want to modify these default routes, we only need to modify them in the RouteServiceProvider.php file. Taking /login as an example, we can change the login route to /login-page. The code is as follows:

//app/Providers/RouteServiceProvider.php
public const HOME = '/home';

//Auth::routes();    
Route::get('/login-page', 'Auth\LoginController@showLoginForm')->name('login');
Route::post('/login', 'Auth\LoginController@login');

In the above code, we commented out the original Auth::routes() method. Then a new route named /login-page is created, which will call the showLoginForm() method of Auth/LoginController for processing.

3. Summary

The routing system in the Laravel framework is an important part of implementing web applications. Modifying the default route is a common requirement in project development. This article introduces the methods of establishing custom routes and modifying the default route, hoping to help everyone better understand the concept and use of routing in the Laravel framework.
