您好,登录后才能下订单哦!
这篇文章将为大家详细讲解有关Laravel如何实现登录失败次数限制,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
在用户身份验证的情况下,Laravel 具有内置的身份验证系统。我们可以根据要求轻松修改它。身份验证中包含的功能之一是Throttling.
为什么我们需要throttling保护?
基本上,throttling是用来保护暴力攻击的。它将在一定时间内检查登录尝试。在短登录中,throttling会计算用户或机器人尝试失败的登录尝试次数。
使用自定义登录实现限制
默认情况下,在内置身份验证控制器中实现限制。但是,如果我们需要实现它到自定义登录呢?
实现自定义登录限制非常容易。首先,我们必须将ThrottlesLogins trait包含到您的控制器中。
use Illuminate\Foundation\Auth\ThrottlesLogins;
现在,将此ThrottlesLogins trait 加到控制器中。
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Foundation\Auth\ThrottlesLogins;
class AuthController extends Controller
{
use ThrottlesLogins;
......现在转到用于对用户进行身份验证的方法。在我的例子中,我使用了 login() POST 方法。并粘贴以下代码:
public function login(Request $request)
{
// Authenticate Inputs
$request->validate([
'username' => 'required',
'password' => 'required|min:6|max:18'
]);
// If the class is using the ThrottlesLogins trait, we can automatically throttle
// the login attempts for this application. We'll key this by the username and
// the IP address of the client making these requests into this application.
if (method_exists($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。
<?php
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
$request->validate([
'username' => 'required',
'password' => 'required|min:6|max:18'
]);
// If the class is using the ThrottlesLogins trait, we can automatically throttle
// the login attempts for this application. We'll key this by the username and
// the IP address of the client making these requests into this application.
if (method_exists($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.']);
}
}
}
