Laravel重写用户登录简单示例

2017年12月12日  | 移动技术网IT编程  | 我要评论

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。
