根因分析

JWT 令牌的声明（如受众、颁发者或过期时间）与服务器期望值不匹配，通常由时钟偏差或配置错误导致。

English

The JWT token's claims (e.g., audience, issuer, or expiration) do not match the server's expected values, often due to clock skew or misconfiguration.

解决方案

  1. Synchronize server and client clocks using NTP, then retry the request. For example, on Linux: `sudo ntpdate pool.ntp.org` or enable `systemd-timesyncd`.
  2. In the server configuration, set a leeway for clock skew (e.g., 30 seconds). For express-jwt: `app.use(jwt({ secret: 'mysecret', clockTolerance: 30 }))`.
  3. Verify that the 'aud' (audience) and 'iss' (issuer) claims in the token match the server's expected values. Update the token generation code or server configuration accordingly.

无效尝试

常见但无效的做法:

  1. 70% 失败

    Token regeneration does not fix clock skew or misconfigured audience/issuer values; the new token will still be rejected.

  2. 90% 失败

    Disabling validation exposes the API to unauthorized access and token forgery.

  3. 80% 失败

    Changing the payload invalidates the signature, leading to a signature verification failure.
