Well key this by the username and // the IP address of the client making these requests into this application. if (method_exists($this, hasTooManyLoginAttempts) $this-hasTooManyLoginAttempts($request)) { $this-fireLockoutEvent($request); return $this-sendLockoutResponse($request); } ....... 首先我们验证了用户提交的输入然后实现了hasTooManyLoginAttempts() 方法。此方法将检查用户在某个时间是否执行过一定数量的失败尝试然后系统将通过sendLockoutResponse() 方法阻止该用户。 现在我们必须通过incrementLoginAttempts()方法指示对ThrottlesLogins trait的失败登录尝试。 if( Auth::attempt([username $username, password $password]) ){ // Redirect to appropriate dashboard } else { // 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 redirect()-back() -withInput($request-all()) -withErrors([error Please check your username / password.]); } 您还可以通过$maxAttempts和$decayMinutes属性更改允许的最大尝试次数和限制的分钟数。在这里您可以找到完整的代码。 namespace App\Http\Controllers; use Illuminate\Http\Request; use Illuminate\Foundation\Auth\ThrottlesLogins; class AuthController extends Controller { use ThrottlesLogins; /** * The maximum number of attempts to allow. * * return int */ protected $maxAttempts 5; /** * The number of minutes to throttle for. * * return int */ protected $decayMinutes 1; public function login(Request $request) { // Authenticate Inputs $request-validate([ username required, password required|min:6|max:18 ]); // If the class is using the ThrottlesLogins trait, we can automatically throttle // the login attempts for this application. Well key this by the username and // the IP address of the client making these requests into this application. if (method_exists($this, hasTooManyLoginAttempts) $this-hasTooManyLoginAttempts($request)) { $this-fireLockoutEvent($request); return $this-sendLockoutResponse($request); } $username $request-username; $password $request-password; if( Auth::attempt([username $username, password $password]) ){ // Redirect to appropriate dashboard } else { // 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 redirect()-back() -withInput($request-all()) -withErrors([error Please check your username / password.]); } } } Related Posts: 总结 到此这篇关于Laravel登录失败次数限制的文章就介绍到这了,更多相关Laravel登录失败次数限制内容请搜索脚本之家以前的文章或继续浏览下面的相关文章希望大家以后多多支持脚本之家
