How to implement the jump function after login in laravel

Laravel is currently the most widely used PHP web framework. Its login function is very commonly used, and jumping to a specified page after successful login is also one of the common requirements. This article will introduce in detail how to implement the jump function after login in Laravel.

2. Create a new project:laravel new project_name
3. Enter the project directory:cd project_name
4. Start Laravel built-in server: php artisan serve

In this article, we will use the default configuration for development, if you have used other configurations, it may be slightly different.

2. Implement the login function

It is very simple to implement the login function in Laravel, you only need to use the Auth middleware. Add the following routes to the routes/web.php file:

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

These two routes correspond to the display of the login page and the processing of the login operation respectively. Among them, the LoginController@showLoginForm method is used to display the login form, and the LoginController@login method is used to process the login request submitted by the user.

If you have not created LoginController, you can quickly create it with the following command:

php artisan make:controller LoginController

In LoginController, you can use the ## provided by Laravel #AuthenticatesUsers trait quickly implements login functionality. Just introduce this trait in the class:

use AuthenticatesUsers;

public function __construct()
{
    $this->middleware('guest')->except('logout');
}

Create the

RedirectIfAuthenticated.php file in the app/Http/Middleware directory, and add the following code: intended

method in the

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;
use Illuminate\Http\Request;

class RedirectIfAuthenticated
{

    {
        if (Auth::guard($guard)->check()) {
            return redirect()->intended('/dashboard');//修改为登录成功后要跳转的路径
        }

I hope this article can help you easily implement the post-login jump function in Laravel!
