以下是此处找到的解决方案的更彻底再现。
我们基本上需要覆盖作为包一部分的 jwt_payload 方法graphql_jwt
。
将此添加到项目的settings.py
GRAPHQL_JWT = {
'JWT_PAYLOAD_HANDLER': 'common.utils.jwt_payload',
}
common
在您拥有该文件的同一目录中的文件夹中创建以下manage.py
文件。
在里面,创建以下两个文件:- 这是我们在sub
属性中添加 user_id 的地方。
实用程序.py
from calendar import timegm
from datetime import datetime
from .settings import jwt_settings
def jwt_payload(user, context=None):
username = user.get_username()
user_id = str(user.id)
if hasattr(username, 'pk'):
username = username.pk
payload = {
user.USERNAME_FIELD: username,
'sub': user_id,
'exp': datetime.utcnow() + jwt_settings.JWT_EXPIRATION_DELTA,
}
if jwt_settings.JWT_ALLOW_REFRESH:
payload['origIat'] = timegm(datetime.utcnow().utctimetuple())
if jwt_settings.JWT_AUDIENCE is not None:
payload['aud'] = jwt_settings.JWT_AUDIENCE
if jwt_settings.JWT_ISSUER is not None:
payload['iss'] = jwt_settings.JWT_ISSUER
return payload
common 文件夹中的这个 settings.py 文件只是一个依赖项。对于 utils.py。
