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 IlluminateHttpRedirectResponse|IlluminateHttpResponse
   */
  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。
