我真的对这个错误感到困惑。我无法弄清楚发生了什么。我正在尝试做的是验证令牌。

const jwt = require("jsonwebtoken");

jwt.verify(token, config.get("jwtSecret"), (err, decoded) => {
  if (err) {
    console.log(err);
    return res.status(401).json({ msg: "Token is not valid" });
  } else {
    console.log(decoded);
    req.user = decoded.user;
    next();
  }
})

错误是

在我追踪代码之后，我发现了解析payload的问题。当库解析payload时，“iat”的值是无效的。这就是错误的来源。图书馆在做什么：

Buffer.from(payload, 'base64').toString(encoding)

它返回什么：


"{"user":{"id":"userId"},"iat":.��n\���ctLf��x�):�'�8}"

但我没有为“iat”字段提供任何自定义选项。这就是我从图书馆自动得到的。

令牌是：
