Question

我想知道如何在未授权的情况下更改express-jwt的响应，我尝试使用错误处理程序，但无法正常工作。

这是我的验证功能

const checkJwt = jwt({
secret: jwksRsa.expressJwtSecret({
      cache: true,
      rateLimit: true,
      jwksRequestsPerMinute: 5,
      jwksUri: `https://dev-88888.com/.well-known/jwks.json`
  }),
 audience:'https://dev-******.com/api/v2/',
    issuer: `https://dev000000.com/`,
    algorithms: ['RS256']
  });

这就是我要得到的

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">

    </head>

        </pre>
    </body>
</html>

但是我想要的是

{
    Error: 'Some Error message'
}

谢谢您的任何帮助。

根据我对文档的了解，您可以使用express传递自定义中间件来进行错误处理

  app.use(function (err, req, res, next) {
     if (err.name === 'UnauthorizedError') {
     res.status(401).send('invalid token...');
     }
    })
