node.js - 如何使用 express-jwt 发送自定义错误响应？

问题描述

我想知道如何在 express-jwt 未经授权时更改它的响应，我尝试使用错误处理程序但它不起作用。

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']
  });

这就是我得到的

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

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

但我想要的是

{
    Error: 'Some Error message'
}

任何帮助将不胜感激，谢谢。

解决方案

根据我从文档中了解到的是，您可以传递一个自定义中间件，express用于错误处理

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