JWT 身份验证流明 5.2 中的错误

我对laravel/lumen框架很陌生。我正在使用 lumen 5.2 来构建一个 restful API。对于身份验证，我正在尝试实现 JWT 身份验证，我正在按照这篇 https://laravelista.com/json-web-token-authentication-for-lumen 文章作为指导。我安装和配置此 https://github.com/tymondesigns/jwt-auth包。它工作正常，如果我不提供令牌{"错误"："token_not_provided"}，它会给我以下错误。但是当我尝试通过在 post 请求中传递电子邮件和密码来生成令牌时，它会失败并给出以下错误。

这是我的身份验证控制器代码：

namespace App'Http'Controllers;
use Illuminate'Http'Exception'HttpResponseException;
use JWTAuth;
use Tymon'JWTAuth'Exceptions'JWTException;
use Illuminate'Http'Request;
use Illuminate'Http'Response as IlluminateResponse;
class AuthController extends Controller{

/**
 * Handle a login request to the application.
 *
 * @param 'Illuminate'Http'Request $request
 * @return 'Illuminate'Http'Response
 */
public function postLogin(Request $request)
{
    try
    {
        $this->validate($request, [
            'email' => 'required|email|max:255', 'password' => 'required',
        ]);
    }
    catch (HttpResponseException $e)
    {
        return response()->json([
            'error' => [
                'message'     => 'Invalid auth',
                'status_code' => IlluminateResponse::HTTP_BAD_REQUEST
            ]],
            IlluminateResponse::HTTP_BAD_REQUEST,
            $headers = []
        );
    }
    $credentials = $this->getCredentials($request);
    try
    {
        // attempt to verify the credentials and create a token for the user
        //$customClaims = ['email' => 'rahul.rksaini@gmail.com', 'password' => 'password'];
        if ( ! $token = JWTAuth::attempt($credentials))
        {
            return response()->json(['error' => 'invalid_credentials'], 401);
        }
    }
    catch (JWTException $e)
    {
        // something went wrong whilst attempting to encode the token
        return response()->json(['error' => 'could_not_create_token'], 500);
    }
    // all good so return the token
    return response()->json(compact('token'));
}
/**
 * Get the needed authorization credentials from the request.
 *
 * @param  'Illuminate'Http'Request  $request
 * @return array
 */
protected function getCredentials(Request $request)
{
    return $request->only('email', 'password');
}

}

我用谷歌搜索了很多，但还没有得到任何解决方案。请帮我弄清楚。

提前谢谢。
