Laravel Auth快速实现用户认证

laravel有自带的登录验证。建立对应的表和配置一些文件就能够使用。

Config配置

在 config/auth.php中，配置示例如下：

'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
 ],

'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
            'hash' => false,
        ],
        'admin' => [
            'driver' => 'session',
            'provider' => 'admins',
        ],
    ],

        'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => AppModelsAuthUser::class,
            'table' => 'blog_users',
        ],

        'admins' => [
            'driver' => 'eloquent',
            'model' => AppModelsAuthAdmin::class,
            'table' => 'blog_admins',
        ],
    ],

laravel 脚手架实现认证体系

进到项目目录创建脚手架，执行：

php artisan make:auth

routes/web.php路由下代码 Auth::routes(); 已有认证的默认的 'guard' => 'web'所有认证路由 database/migrations目录下已有创建表的代码

public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }

项目目录下执行：php artisan migrate ，把表加入数据库 上面错误只需要在 Providers/AppServiceProvider.php boot() 中添加 Schema::defaultStringLength(191); 控制器在 appHttpControllersAuth 目录下。

上面 guards 配置了后台用户认证，下面仿照进行用户认证

路由配置：

//后台注册只在登录后暂未配置路由
Route::group(['prefix' => 'admin', ], function () {
    Route::get('/login', 'AuthAdminLoginController@showAdminLoginForm');
    Route::post('/login', 'AuthAdminLoginController@login');
    Route::post('/logout', 'AuthAdminLoginController@logout')->name('admin.logout');

    Route::group(['middleware' => 'auth:admin', ], function () {
            //后台认证路由

        });
});

复制 app/Http/ControllersAuth 下的 LoginController.php和RegisterController.php 到新建目录 app/Http/Controllers/Auth/Admin 下。 LoginController.php

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

        protected function guard()
    {
        return Auth::guard('admin');
    }

        public function showAdminLoginForm()
    {
        return view('admin.auth.login', ['guard' => 'admin']);
    }

        public function login(Request $request)
    {
        $this->validate($request, [
            'email' => 'required|email',
            'password' => 'required'
        ]);

        if (Auth::guard('admin')->attempt(['email' => $request->email, 'password' => $request->password], $request->get('remember'))) {

            return redirect()->intended('/admin');
        }
        return back()->withInput($request->only('email', 'remember'))->withErrors(['password' => 'Invalid account or password.']);
    }

        public function logout(Request $request)
    {
        $this->guard()->logout();

        $request->session()->forget($this->guard()->getName());

        $request->session()->regenerate();

        return redirect('/admin');
    }

RegisterController.php

protected $redirectTo = '/admin';

public function __construct()
    {
        $this->middleware('guest:admin');
    }

        protected function guard()
    {
        return Auth::guard('admin');
    }

        protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255'],
            'password' => ['required', 'string', 'min:8', 'confirmed'],
        ]);
    }

        public function showAdminRegisterForm()
    {
        return view('admin.auth.register', ['guard' => 'admin']);
    }

        protected function create(Request $request)
    {
        $this->validator($request->all())->validate();
        $admin = Admin::create([
            'name' => $request['name'],
            'email' => $request['email'],
            'password' => Hash::make($request['password']),
        ]);
        return redirect()->intended('admin/login');
    }

模板将 resources/views/auth 目录复制到 resources/views/admin 中间件 RedirectIfAuthenticated.php 改一下：

public function handle($request, Closure $next, $guard = null)
    {
        if ($guard == "admin") {
            if (Auth::guard($guard)->check()) {
                return redirect('/admin');
            }
        } elseif($guard == null) {
            if (Auth::guard($guard)->check() &&
                ! $request->is('email/*', 'logout', 'password/*')) {
                return redirect('/');
            }
        }

        return $next($request);
    }

新建admins表：

php artisan make:migration create_admins_table --create=admins

database/migrations 目录下新建admins表文件下编辑：

public function up()
    {
        Schema::create('admins', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }

再php artisan migrate，创建表到数据库。 php artisan make:seeder AdminsTableSeeder创建填充后台用户数据的文件

public function run()
    {
        DB::table('admins')->insert([
            'name'  => 'admin',
            'email' => '[email protected]',
            'password' => bcrypt('12345678'),
        ]);
    }

DatabaseSeeder.php文件改为

public function run()
    {
        $this->call(AdminTableSeeder::class);
    }

php artisan db:seed --class=AdminsTableSeeder 执行单个数据填充命令 新建App/Models/Auth/Admin.php,将下面代码写入文件：

<?php

namespace AppModelsAuth;

use IlluminateNotificationsNotifiable;
use IlluminateFoundationAuthUser as Authenticatable;

class Admin extends Authenticatable
{
    use Notifiable;

    protected $table = 'admins';

    protected $guard = 'admin';

    protected $fillable = [
        'name', 'email', 'password',
    ];

    protected $hidden = [
        'password', 'remember_token',
    ];
}
