如何在 django-graphql-jwt 中配置 JWT 令牌以获取令牌中的 userId 而不仅仅是用户名?
How to configure the JWT token in django-graphql-jwt to obtain the userId in the token instead of just the username?
TLDR - 但默认情况下从后端发送的 JWT 令牌仅包含用户名。我想要 userId,因为 well.This 是它当前包含的内容:-
HEADER:ALGORITHM & TOKEN TYPE
{
"typ": "JWT",
"alg": "HS256"
}
PAYLOAD:DATA
{
"username": "admin", <---- I have the username already. Need the userId as well!
"exp": 1621845856,
"origIat": 1621845556
}
VERIFY SIGNATURE
HMACSHA256(
base64UrlEncode(header) + "." +
base64UrlEncode(payload),
your-256-bit-secret
) secret base64 encoded
我有一个 Django GraphQL API(使用 Graphene、django-graphql-auth、django-graphql-jwt)和一个 Angular 前端。我有完整的身份验证设置。现在我面临的问题是我将令牌存储在本地存储中,因此当用户再次打开浏览器时,我想验证该令牌并仅使用其中的信息来获取用户的 ID 然后使用它userId 来获取他们的用户个人资料信息,这是完成登录过程的必要步骤。
我不确定如何自定义负载以包含 userId。这样当用户在关闭后打开浏览器时,我可以简单地使用令牌中的信息来完全登录。我对 Python 和 Django 都很陌生。我无法在网上的任何地方找到详细的过程,也许我没有在寻找正确的东西或在正确的地方。详细说明会很有帮助。
以下是对 here.
找到的解决方案的更彻底再现
我们基本上需要覆盖作为 graphql_jwt
包的一部分的 jwt_payload 方法。
将此添加到项目的 settings.py
GRAPHQL_JWT = {
'JWT_PAYLOAD_HANDLER': 'common.utils.jwt_payload',
}
在 common
文件夹中创建以下文件,该文件夹位于 manage.py
文件所在的同一目录中。
在内部,创建以下两个文件:-
这是我们在 sub
属性中添加 user_id 的地方。
utils.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.
