Laravel重写用户登录简单示例


            本文实例讲述了Laravel重写用户登录的方法。分享给大家供大家参考，具体如下：





class AuthController extends Controller

{

  //

  use ThrottlesLogins, AuthenticatesAndRegistersUsers;

  protected $redirectTo = 'admin/index';

  protected $loginView = 'admin/login';

  protected $guard = 'admin';

  protected $redirectAfterLogout = 'admin/login';

  protected $maxLoginAttempts = 5; //每分钟最大尝试登录次数

  protected $lockoutTime = 600; //登录锁定时间

  function __construct()

  {

    $this->middleware('guest:admin', ['except' => 'logout']);

  }

  protected function validator(array $data)

  {

    return Validator::make($data, [

      'username' => 'required|max:255',

      'email' => 'required|email|max:255|unique:admin_users',

      'password' => 'required|confirmed|min:6',

    ]);

  }

  /**

   * @param Request $request

   */

  protected function validateLogin(Request $request)

  {

    $this->validate($request,[

      $this->loginUsername() => 'required',

      'password' => 'required',

      'captcha' => 'required|captcha'

    ], [

      'email.required' => '邮箱必须',

      'password.required' => '密码必须',

      'captcha.captcha' => '验证码错误',

      'captcha.required' => '验证码必须',

    ]);

  }

  /**

   * 重写登录

   * @param Request $request

   * @return \Illuminate\Http\RedirectResponse|\Illuminate\Http\Response

   */

  public function login(Request $request)

  {

    $this->validateLogin($request);

    // If the class is using the ThrottlesLogins trait, we can automatically throttle

    // the login attempts for this application. We'll key this by the username and

    // the IP address of the client making these requests into this application.

    $throttles = $this->isUsingThrottlesLoginsTrait();

    //dd($this->hasTooManyLoginAttempts($request));

    if ($throttles && $lockedOut = $this->hasTooManyLoginAttempts($request)) {

      $this->fireLockoutEvent($request);

      //日志记录

      $this->login_logs(['email'=>$request->input('email'), 'login_ip'=>$request->ip(), 'login_result'=>0, 'comments'=>'限制登录10分钟']);

      return $this->sendLockoutResponse($request);

    }

    $credentials = $this->getCredentials($request);

    if (Auth::guard($this->getGuard())->attempt($credentials, $request->has('remember'))) {

      //日志记录

      $this->login_logs(['email'=>$request->input('email'), 'login_ip'=>$request->ip(), 'login_result'=>1, 'comments'=>'登录成功']);

      return $this->handleUserWasAuthenticated($request, $throttles);

    }

    // If the login attempt was unsuccessful we will increment the number of attempts

    // to login and redirect the user back to the login form. Of course, when this

    // user surpasses their maximum number of attempts they will get locked out.

    if ($throttles && ! $lockedOut) {

      //日志记录

      $this->login_logs(['email'=>$request->input('email'), 'login_ip'=>$request->ip(), 'login_result'=>0, 'comments'=>'登录失败']);

      $this->incrementLoginAttempts($request);

    }

    return $this->sendFailedLoginResponse($request);

  }

  /**

   * 登录记录

   * @param $data

   */

  private function login_logs ($data)

  {

    LoginLog::create($data);

  }

}







直接重写login方法，其实我是复制了原方法然后加入了一些自己的东西。

主要的一些修改就是：

1. 加入验证码（自定义了验证信息及提示）。

2. 后台登录频率的限制。

3. 登录日志记录。
