基本步骤:
一、自定义用户表:
1、自定义的用户表继承AbstractUser;
2、settings.py添加配置,指向用户表:AUTH_USER_MODEL = 'myUser.Account'(子项目名称.用户表models名称);
3、python manage.py makemigrations
4、python manage.py migrate
二、自定义登录验证:
# 签发:
jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER
# 生成token:
jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER
三、获取当前登录用户:
# 通过headers获取token:
token = request.META.get('HTTP_AUTHORIZATION')
# 情况一:token的传参格式为JWT xxxx
token = request.META.get('HTTP_AUTHORIZATION')[4:]
# 情况二:token的传参格式为TOKEN xxxx
token = request.META.get('HTTP_AUTHORIZATION')[7:]
# 然后解析出user_id和username:
jwt_decode_handler = api_settings.JWT_DECODE_HANDLER
