Laravel5.5 实现后台管理登录(自定义用户表登录)

本文主要是介绍Laravel5.5 实现后台管理登录(自定义用户表登录)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

最近群里很多人文档，laravel如何做会员和管理两个身份登录，今天把教程分享一下

自定义用户表登录

认证是由 guards 和 providers 两部分构成的， defaults 配置是默认选择一个 guard 认证驱动，所以我们在这两个配置项中分别添加一个 admin 和 admins 选项。

<?php
  'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        'admin' => [
            'driver' => 'session',
            'provider' => 'admins',
        ],
  'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\User::class,
        ],
        'admins' => [
            'driver' => 'eloquent',
            'model' => App\Models\Admin::class,
        ],
    ],

标红的是我们后添加的后台管理员登录身份

创建后台用户表和model

php artisan make:model Admin
php artisan make:migration creaet_admins_table

在数据库迁移文件 _create_admins_table , 我们可以复制 users 迁移文件里的字段

Schema::create('admins', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('email');
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });

执行php artisan migrate

生成临时数据

在 database/factories/ModelFactory.php, 添加如下数据：

$factory->define(App\Admin::class, function (Faker\Generator $faker) {
    static $password;

    return [
        'name' => $faker->name,
        'password' => $password ?: $password = bcrypt('123456'),
        'email' =>  $faker->email,
        'remember_token' => str_random(10),
    ];
});

打开命令行输入：

php artisan tinker
use App;
factory(App\Admin::class,5)->create()
//生成5条测试数据，你要几条就输入多少(Class,num)

更改 Admin 模型类

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Admin extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

创建控制器

php artisan make:controller Admin/LoginController
php artisan make:controller Admin/AdminController

编辑 Admin/LoginController.php：

<?php

namespace App\Http\Controllers\Admin;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesUsers;

class LoginController extends Controller
{
    use AuthenticatesUsers;

    /**
     * Where to redirect users after login / registration.
     *
     * @var string
     */
    protected $redirectTo = '/admin/index';
    protected $username;

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest:admin', ['except' => 'logout']);
        $this->username = config('admin.global.username');
    }

    /**
     * 重写登录视图页面
     */
    public function showLogin()
    {
        return view('admin.login.index');
    }

    /**
     * 自定义认证驱动
     * @return mixed
     */
    protected function guard()
    {
        return auth()->guard('admin');
    }

}

修改 app\Http\Middleware\RedirectIfAuthenticated.php:

public function handle($request, Closure $next, $guard = null)
    {
        if (Auth::guard($guard)->check()) {
            // 根据不同 guard 跳转到不同的页面
            $url = $guard ? 'admin/dash':'/home';
            return redirect($url);
        }

        return $next($request);
    }

编辑 Admin\AdminController.php：

<?php

namespace App\Http\Controllers\Admin;

use App\Http\Controllers\Controller;

class AdminController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth.admin:admin');
    }
    //
    public function index()
    {
        dd('用户名：'.auth('admin')->user()->name);
    }

编辑 app\Http\Middleware\AdminAuthMiddleware.php

public function handle($request, Closure $next, $guard = null)
    {
        if (Auth::guard($guard)->guest()) {
            if ($request->ajax() || $request->wantsJson()) {
                return response('Unauthorized.', 401);
            } else {
                return redirect()->guest('admin/login');
            }
        }
        return $next($request);
    }

在 app\Http\Kernel.php 中注册:

protected $routeMiddleware = [
       ··· ···
        'auth.admin' => \App\Http\Middleware\AdminAuthMiddleware::class,
    ];

注册路由

编辑 routes/web.php ：

Route::group(['prefix' => 'admin','namespace' => 'Admin'],function ($router)
{
    $router->get('login', 'LoginController@showLogin')->name('admin.login');
    $router->post('login', 'LoginController@login');
    $router->post('logout', 'LoginController@logout');

    $router->get('index', 'AdminController@index');
});
