JWT模式下生成token加解密 

 1 from datetime import datetime, timedelta
 2 from config import settings
 3 import jwt

 5 import requests as req

29     utcnow() utc是世界时 不管你设置的是哪个时区 utcnow()也是获取服务器事件
30     datetime.now() 获取当前服务器的时间
31     为什么要用get_web_now_time()      get_web_now_time()获取的是baidu的网络时间为了避免当前服务器出错
32     timedelta 延迟时间
33     JWT_SECRET_KEY = "WangYafengisahandsomeman2022"
34     JWT_ALGORITHM = "HS256"
35     JWT_ACCESS_TOKEN_EXPIRE_MINUTES = 24 * 60 * 7

运行结果：

解密：

token = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJuYW1lIjoid3lmIiwicGFzc3dvcmQiOiIxMjM0NTYiLCJleHAiOjE2NjMyMjU4ODZ9.hFTbjdD4BlsMSWOlgQ9vLiDtwpRTa_mQkcnETIIKXng"

payload = jwt.decode(token, settings.JWT_SECRET_KEY, algorithms=[settings.JWT_ALGORITHM])

print(payload)
