laravel利用auth完成后台的登录模块
开发环境：windows10、iis、php7.3，安装好laravel
1、创建管理员admin数据表
(1)命令提示符执行：php artisan make:migration create_admin_table
(2)修改database/migration/*_create_admin_table.php中的up()方法，如下：
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateAdminsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
//php artisan make:migration create_users_table
//php artisan migrate
public function up()
{
Schema::create('admins', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->integer('mobile')->unique();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('admins');
}
}
（3）终端执行 php artisan migrate 这时候，数据库会自动添加表admin。
（4）修改一下表中字段的字段长度，例如varchar(255).
当然，手动建表也可以。
2、生产数据表模型
php artisan make:model Models/Admin,会自动创建Models/Admin.php这个模型文件，修改为：
<?php namespace App\Models; 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', ]; }
3、添加后台后台路由
Route::prefix('admin')->namespace('Admin')->group(function () { //后台首页 $this->get('login', 'LoginController@showLoginForm')->name('admin.login'); $this->post('login', 'LoginController@login'); $this->post('logout', 'LoginController@logout')->name('admin.logout'); });
4、新建管理员登录控制器
php artisan make:controller Admin/LoginController
并添加代码如下（参考auth/LoginController）：
<?php namespace App\Http\Controllers\Admin; use App\Http\Controllers\Controller; use Illuminate\Foundation\Auth\AuthenticatesUsers; use Illuminate\Http\Request; class LoginController extends Controller { /* |-------------------------------------------------------------------------- | Login Controller |-------------------------------------------------------------------------- | | This controller handles authenticating users for the application and | redirecting them to your home screen. The controller uses a trait | to conveniently provide its functionality to your applications. | */ use AuthenticatesUsers; /** * Where to redirect users after login. * * @var string */ protected $redirectTo = '/admin'; /** * Create a new controller instance. * * @return void */ public function __construct() { $this->middleware('guest:admin')->except('logout'); } public function showLoginForm() { return view('admin.login'); } protected function guard() { return auth()->guard('admin'); } /** * 后台管理员退出跳转到后台登录页面 * Log the user out of the application. * * @param \Illuminate\Http\Request $request * @return \Illuminate\Http\Response */ public function logout(Request $request) { $this->guard()->logout(); $request->session()->invalidate(); return redirect('/admin/login'); } protected function attemptLogin(Request $request) { $username = $request->input('username'); $password = $request->input('password'); // 验证用户名登录方式 $usernameLogin = $this->guard()->attempt( ['name' => $username, 'password' => $password], $request->has('remember') ); if ($usernameLogin) { return true; } // 验证手机号登录方式 $mobileLogin = $this->guard()->attempt( ['mobile' => $username, 'password' => $password], $request->has('remember') ); if ($mobileLogin) { return true; } // 验证邮箱登录方式 $emailLogin = $this->guard()->attempt( ['email' => $username, 'password' => $password], $request->has('remember') ); if ($emailLogin) { return true; } return false; } protected function validateLogin(Request $request) { $request->validate([ $this->username() => 'required|string', 'password' => 'required|string', ]); } public function username() { return 'username'; } }
5、添加管理员认证，修改config/auth.php文件：
'guards' => [ 'web' => [ 'driver' => 'session', 'provider' => 'users', ], 'admin' => [ 'driver' => 'session', 'provider' => 'admins', ], 'api' => [ 'driver' => 'token', 'provider' => 'users', ], ],
'providers' => [ 'users' => [ 'driver' => 'eloquent', 'model' => App\User::class, ], 'admins' => [ 'driver' => 'eloquent', 'model' => App\Models\Admin::class, ] // 'users' => [ // 'driver' => 'database', // 'table' => 'users', // ], ],
6、创建admin登录所用的中间件
php artisan make:middleware AdminAuthMiddleware
添加代码如下：
<?php namespace App\Http\Middleware; use Closure; use Illuminate\Support\Facades\Auth; class AdminAuthMiddleware { /** * Handle an incoming request. * * @param \Illuminate\Http\Request $request * @param \Closure $next * @return mixed */ public function handle($request, Closure $next, $guard = null) { //当 auth 中间件判定某个用户未认证，会返回一个 JSON 401 响应，或者，如果不是 Ajax 请求的话，将用户重定向到 login 命名路由（也就是登录页面）。 if (Auth::guard($guard)->guest()) { if ($request->ajax() || $request->wantsJson()) { return response('Unauthorized.', 401); } else { return redirect()->guest('admin/login'); } } return $next($request); } }
接下来去app\Http\Kernel.php protected $routeMiddleware里面注册该中间件
'auth.admin' => \App\Http\Middleware\AdminAuthMiddleware::class,
然后在后台并在web.php中使用此中间件，添加后台中间件
Route::prefix('admin')->namespace('Admin')->group(function () { //后台首页 $this->get('login', 'LoginController@showLoginForm')->name('admin.login'); $this->post('login', 'LoginController@login'); $this->post('logout', 'LoginController@logout')->name('admin.logout'); Route::middleware('auth.admin:admin')->name('admin.')->group(function () { Route::get('/', 'HomeController@index'); }); });
7、创建后台首页控制器
此时我们的Admin\HomeController并未创建
创建后台首页路由
php artisan make:controller Admin/HomeController
增加一条路由规则，加载后台首页
public function index() { // dd('后台首页，当前管理员：' . auth('admin')->user()->name); return view('admin.index'); }
8、创建后台首页与登录页模板
resources/view/admin/index.blade.php
resources/view/admin/login.blade.php
