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。
