JWT签名详解

JWT签名详解，JAVA示例，点击->JWT详解

Python JWT对称签名

import jwt
class JwtToken(object):
    _salt = "gz"
    _expire_message = dict(code=1200, msg="token 已经失效")
    _unknown_error_message = dict(code=4200, msg="token 解析失败")
    @classmethod
    def generate_token(cls, payload: dict) -> str:
        headers = dict(typ="jwt", alg="HS256")
        resut = jwt.encode(payload=payload, key=cls._salt, algorithm="HS256", headers=headers)
        return resut
    @classmethod
    def parse_token(cls, token: str) -> tuple:
        verify_status = False
        try:
            payload_data = jwt.decode(token, cls._salt, algorithms=['HS256'])
            verify_status = True
        except jwt.ExpiredSignatureError:
            payload_data = cls._expire_message
        except Exception as _err:
            payload_data = cls._unknown_error_message
        return verify_status, payload_data
jwt_token = JwtToken.generate_token({"user": "xiongfanyong"})
print(jwt_token)
print(JwtToken.parse_token(jwt_token))
