Laravel 中Auth类自定义用法

https://laravelacademy.org/index.php/post/19484.html

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。

1. <?php
2. ‘guards’ => [
3. ‘web’ => [
4. ‘driver’ => ‘session’,
5. ‘provider’ => ‘users’,
6. ],
7. ‘admin’ => [
8. ‘driver’ => ‘session’,
9. ‘provider’ => ‘admins’,
10. ],
11. ‘providers’ => [
12. ‘users’ => [
13. ‘driver’ => ‘eloquent’,
14. ‘model’ => App\User::class,
15. ],
16. ‘admins’ => [
17. ‘driver’ => ‘eloquent’,
18. ‘model’ => App\Models\Admin::class,
19. ],
20. ],

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

1. php artisan make:model Admin
2. 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

1. Schema::create(‘admins’, function (Blueprint $table) {
2. $table->increments(‘id’);
3. $table->string(‘name’);
4. $table->string(‘email’);
5. $table->string(‘password’);
6. $table->rememberToken();
7. $table->timestamps();
8. });

执行php artisan migrate

生成临时数据

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

1. $factory->define(App\Admin::class, function (Faker\Generator $faker) {
2. static $password;
4. return [
5. ‘name’ => $faker->name,
6. ‘password’ => $password ?: $password = bcrypt(‘123456’),
7. ‘email’ => $faker->email,
8. ‘remember_token’ => str_random(10),
9. ];
10. });

打开命令行输入：

1. php artisan tinker
2. use App;
3. factory(App\Admin::class,5)->create()
4. //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

1. <?php
3. namespace App;
5. use Illuminate\Notifications\Notifiable;
6. use Illuminate\Foundation\Auth\User as Authenticatable;
8. class Admin extends Authenticatable
9. {
10. use Notifiable;
12. /**
13. • The attributes that are mass assignable.
14. *
15. • @var array
16. */
17. protected $fillable = [
18. ‘name’, ‘email’, ‘password’,
19. ];
21. /**
22. • The attributes that should be hidden for arrays.
23. *
24. • @var array
25. */
26. protected $hidden = [
27. ‘password’, ‘remember_token’,
28. ];
29. }

创建控制器

1. php artisan make:controller Admin/LoginController
2. php artisan make:controller Admin/AdminController

编辑 Admin/LoginController.php：

1. <?php
3. namespace App\Http\Controllers\Admin;
5. use Illuminate\Http\Request;
6. use App\Http\Controllers\Controller;
7. use Illuminate\Foundation\Auth\ThrottlesLogins;
8. use Illuminate\Foundation\Auth\AuthenticatesUsers;
10. class LoginController extends Controller
11. {
12. use AuthenticatesUsers;
14. /**
15. • Where to redirect users after login / registration.
16. *
17. • @var string
18. */
19. protected $redirectTo = ‘/admin/index’;
20. protected $username;
22. /**
23. • Create a new controller instance.
24. *
25. • @return void
26. */
27. public function __construct()
28. {
29. $this->middleware(‘guest:admin’, [‘except’ => ‘logout’]);
30. $this->username = config(‘admin.global.username’);
31. }
33. /**
34. • 重写登录视图页面
35. */
36. public function showLogin()
37. {
38. return view(‘admin.login.index’);
39. }
41. /**
42. • 自定义认证驱动
43. • @return mixed
44. */
45. protected function guard()
46. {
47. return auth()->guard(‘admin’);
48. }
51. }

修改 app\Http\Middleware\RedirectIfAuthenticated.php:

1. public function handle($request, Closure $next, $guard = null)
2. {
3. if (Auth::guard($guard)->check()) {
4. // 根据不同 guard 跳转到不同的页面
5. $url = $guard ? ‘admin/dash’:’/home’;
6. return redirect($url);
7. }
9. return $next($request);
10. }

编辑 Admin\AdminController.php：

1. <?php
3. namespace App\Http\Controllers\Admin;
5. use App\Http\Controllers\Controller;
7. class AdminController extends Controller
8. {
9. /**
10. • Create a new controller instance.
11. *
12. • @return void
13. */
14. public function __construct()
15. {
16. $this->middleware(‘auth.admin:admin’);
17. }
18. //
19. public function index()
20. {
21. dd(‘用户名：’.auth(‘admin’)->user()->name);
22. }

编辑 app\Http\Middleware\AdminAuthMiddleware.php

1. public function handle($request, Closure $next, $guard = null)
2. {
3. if (Auth::guard($guard)->guest()) {
4. if ($request->ajax() || $request->wantsJson()) {
5. return response(‘Unauthorized.’, 401);
6. } else {
7. return redirect()->guest(‘admin/login’);
8. }
9. }
10. return $next($request);
11. }

在 app\Http\Kernel.php 中注册:

1. protected $routeMiddleware = [
2. ··· ···
3. ‘auth.admin’ => \App\Http\Middleware\AdminAuthMiddleware::class,
4. ];

注册路由

编辑 routes/web.php ：

1. Route::group([‘prefix’ => ‘admin’,’namespace’ => ‘Admin’],function ($router)
2. {
3. $router->get(‘login’, ‘LoginController@showLogin’)->name(‘admin.login’);
4. $router->post(‘login’, ‘LoginController@login’);
5. $router->post(‘logout’, ‘LoginController@logout’);
7. $router->get(‘index’, ‘AdminController@index’);
8. });

视图文件创建和修改

复制 resources\views\auth\login.blade.php,到 resources\views\admin\login\index.blade.php,修改表单提交地址

1. {{ url(‘/login’) }} 改成 {{ route(‘admin.login’) }}

访问 你的站点/admin/login
