Laravel – Auth 自定义登录验证

1、修改config\auth.php配置文件

'model' => App\Model\Users::class,  
'table' => 'users',

2、 修改Users模型类如下：

use Illuminate\Database\Eloquent\Model;  
use Illuminate\Auth\Authenticatable;  
use Illuminate\Auth\Passwords\CanResetPassword;  
use Illuminate\Foundation\Auth\Access\Authorizable;  
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;  
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;  
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;  

class Users extends Model implements AuthenticatableContract,  AuthorizableContract,  CanResetPasswordContract  
{  
  //使用auth验证必须继承接口  
  use Authenticatable, Authorizable, CanResetPassword;  
  //修改为自己的用户表  
  protected $table = 'users';  

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

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

3、修改AuthController控制器

class AuthController extends Controller  
{  
  use ThrottlesLogins /* , AuthenticatesAndRegistersUsers*/ ; //因为没有注册功能可以将AuthenticatesAndRegistersUsers注释掉  
  protected $redirectPath = '/admin';  
  protected $redirectAfterLogout = '/auth/login';  //注销后的跳转地址  

  public function __construct()  
  {  
    $this->middleware('guest', ['except' => ['getlogout']]); //在中间件中排除 getlogout函数 ,否则无法注销  
  }  
  function login() {  
    return view('admin.users.login');  
  }  
  function getlogout() {  
  if(Auth::check()){  
      Auth::logout();  //退出登录  
  }  
      return redirect('/auth/login');  
  }  
  function auth(Request $request) {  
    $user=$request->only(['name','password']);  
    if(Auth::attempt($user,$request->remember)){ //验证密码 通过后合一用Auth::user() 获取登录用户信息 也可以使用 Auth::loginUsingId($user->id) 来登录  
        return redirect()->intended('/admin');  
    }else{  
      return redirect('/auth/login')->withErrors(['login failed'])->withInput($request->except('password'));  
    }  
  }  
  public function redirectPath()  //重构未登录时的跳转地址  
  {  
    return '/admin';  
  }  
}  

4、修改文件不同文件 redirectPath

guest中间件：app/Http/Middleware/RedirectIfAuthenticated.php

public function handle($request, Closure $next)  
  {  
  if ($this->auth->check()) {  
                return redirect('/admin');  //修改登录页面默认登陆后的跳转地址  
  }  
  return $next($request);  
  }  

auth中间件：app/Http/Middleware/Authenticate.php

public function handle($request, Closure $next)  
    {  
        if ($this->auth->guest()) {  
            if ($request->ajax()) {  
                return response('Unauthorized.', 401);  
            } else {  
                return redirect()->guest('auth/login');  
            }  
        }  
        return $next($request);  
    } 

5、添加路由

Route::group(['namespace' => 'Auth','prefix'=>'auth'],function(){   
    route::get('/login','AuthController@login');   
    route::get('/logout','AuthController@getlogout');   
    route::post('/login','AuthController@auth');   
});  
route::get('/admin',['namespace' => 'Admin','middleware' => 'auth'],'AdminController@index');
