Laravel 5.6 Passport OAuth 最大登录尝试次数

我刚刚使用 Laravel Passport 创建了一个简单的 OAuth 系统。该系统将负责外部应用程序的用户注册和身份验证。一切都按我的预期进行，现在我想实现一种机制，在预定义的失败登录尝试次数后锁定用户。

我是 Laravel 和 Passport 的新手，有没有内置包可以帮我管理这个？还是我必须自己开发这个功能？如果是这样，我怎样才能完成这样的任务？

我一直在互联网上搜索，但到目前为止我找不到任何有关 Passport OAuth 的信息。

我已经成功完成了我想做的事情，如果有人遇到这个问题，这就是我所做的......

创建了自定义 AuthController 和登录方法来替换 Laravel Passport 的默认 oauth/token：

use Symfony\Bridge\PsrHttpMessage\Factory\DiactorosFactory;
use Illuminate\Http\Response;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Response;
use \Laravel\Passport\Http\Controllers\AccessTokenController as AccessTokenController;

class AuthController extends AccessTokenController
{
    use AuthenticatesUsers;

    //custom login method
    public function login(Request $request)
    {
        //...
    }
}

在执行任何其他登录操作之前，请检查用户是否已达到最大登录尝试次数：

//custom login method
public function login(Request $request)
{
    //check if the max number of login attempts has been reached
    if ($this->hasTooManyLoginAttempts($request)) 
    {
        $this->fireLockoutEvent($request);

        return "To many attempts...";
    }

    //...
}

通过尝试登录来验证用户凭据。如果登录成功，则会重置失败尝试计数。如果失败，则增加计数：

//check if user has reached the max number of login attempts

//verify user credentials
$credentials = $request->only('email', 'password');

if (Auth::attempt($credentials)) 
{       
    //reset failed login attemps
    $this->clearLoginAttempts($request);

    //...
}
else
{       
    //count user failed login attempts
    $this->incrementLoginAttempts($request);

    return "Login failed...";
}

最后，由于 Passport (OAuth2) 使用 PSR-7 请求（服务器请求接口），我们需要将标准 Laravel 请求转换为 PSR-7 才能颁发访问令牌：

//Authentication passed...

//convert Laravel Request (Symfony Request) to PSR-7
$psr7Factory = new DiactorosFactory();
$psrRequest = $psr7Factory->createRequest($request);

//generate access token
$tokenResponse = parent::issueToken($psrRequest);

//return issued token
return Response::json($tokenResponse);

完整的登录方法如下：

public function login(Request $request)
{
    //check if user has reached the max number of login attempts
    if ($this->hasTooManyLoginAttempts($request)) 
    {
        $this->fireLockoutEvent($request);

        return "To many attempts...";
    }


    //verify user credentials
    $credentials = $request->only('email', 'password');

    if (Auth::attempt($credentials)) 
    {
        //Authentication passed...

        //reset failed login attemps
        $this->clearLoginAttempts($request);

        //convert Laravel Request (Symfony Request) to PSR-7
        $psr7Factory = new DiactorosFactory();
        $psrRequest = $psr7Factory->createRequest($request);

        //generate access token
        $tokenResponse = parent::issueToken($psrRequest);

        //return issued token
        return Response::json($tokenResponse);
    } 
    else 
    {
        //count user failed login attempts
        $this->incrementLoginAttempts($request);

        return "Login failed...";
    }
}
