Auth0错误消息“可疑请求需要验证”是什么意思？

const express = require('express');
const { expressjwt: jwt } = require('express-jwt');
const { expressJwtSecret } = require('jwks-rsa');

const app = express();

// 配置Auth0
const authConfig = {
  domain: 'your-auth0-domain.auth0.com',
  audience: 'your-api-audience',
  issuer: `https://${authConfig.domain}/`,
  algorithms: ['RS256']
};

app.use(jwt({
  secret: expressJwtSecret(authConfig),
  audience: authConfig.audience,
  issuer: authConfig.issuer,
  algorithms: authConfig.algorithms
}));

app.get('/api/data', (req, res) => {
  // 处理请求
  res.json({ message: 'Hello, world!' });
});

app.use((err, req, res, next) => {
  if (err.name === 'UnauthorizedError') {
    // 处理“可疑请求需要验证”的错误
    res.status(401).json({ error: '需要验证' });
  } else {
    next(err);
  }
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
