根因分析
JWT 使用的签名密钥与验证时的密钥不同,或算法不匹配。
English
JWT was signed with a different secret/key than the one used to verify, or the algorithm was mismatched.
解决方案

95% 成功率
payload = jwt.decode(token, SECRET_KEY, algorithms=['HS256'])
-
93% 成功率
SECRET_KEY = os.environ['JWT_SECRET'] # same in issuer and verifier
