Laravel 5.4 / 5.5
login()通过将此功能放在您的中来覆盖默认功能
LoginController：
public function login(IlluminateHttpRequest $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. if ($this->hasTooManyLoginAttempts($request)) { $this->fireLockoutEvent($request); return $this->sendLockoutResponse($request); } // This section is the only change if ($this->guard()->validate($this->credentials($request))) { $user = $this->guard()->getLastAttempted(); // Make sure the user is active if ($user->active && $this->attemptLogin($request)) { // Send the normal successful login response return $this->sendLoginResponse($request); } else { // Increment the failed login attempts and redirect back to the // login form with an error message. $this->incrementLoginAttempts($request); return redirect() ->back() ->withInput($request->only($this->username(), 'remember')) ->withErrors(['active' => 'You must be active to login.']); } } // 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. $this->incrementLoginAttempts($request); return $this->sendFailedLoginResponse($request);}login()建议在此问题的许多其他答案上覆盖这种方式的方法，因为它使您仍然可以使用Laravel
5.4+的许多更高级的身份验证功能，例如登录限制，多个身份验证防护驱动程序/提供程序等。仍然允许您设置自定义错误消息。
Laravel 5.3
更改或覆盖您的
postLogin()函数，
AuthController如下所示：
public function postLogin(Request $request){ $this->validate($request, [ 'email' => 'required|email', 'password' => 'required', ]); $credentials = $this->getCredentials($request); // This section is the only change if (Auth::validate($credentials)) { $user = Auth::getLastAttempted(); if ($user->active) { Auth::login($user, $request->has('remember')); return redirect()->intended($this->redirectPath()); } else { return redirect($this->loginPath()) // Change this to redirect elsewhere ->withInput($request->only('email', 'remember')) ->withErrors([ 'active' => 'You must be active to login.' ]); } } return redirect($this->loginPath()) ->withInput($request->only('email', 'remember')) ->withErrors([ 'email' => $this->getFailedLoginMessage(), ]);}此代码将重定向回登录页面，并显示一条有关用户处于非活动状态的错误消息。如果要重定向到身份验证页面，则可以更改我用注释标记的行
Change this toredirect elsewhere。
