我正在与Django和Graphene一起进行一个项目,Django_graphql_auth库用于处理身份验证,我被要求自定义登录失败时收到的错误消息。我已经阅读了文档中关于如何执行此操作的内容,其中只提到了一个名为CUSTOM_ERROR_TYPE(https://django-graphql-auth.readthedocs.io/en/latest/settings/#custom_error_type)的设置,但我认为我不了解如何使用它,或者可能它没有按照我认为的方式工作。在我的文件中,我:
自定义_errors.py
import graphene
class CustomErrorType(graphene.Scalar):
@staticmethod
def serialize(errors):
return {"my_custom_error_format"}
设置.py
from .custom_errors import CustomErrorType
GRAPHQL_AUTH = {
'CUSTOM_ERROR_TYPE': CustomErrorType,
}
user.py
class AuthRelayMutation(graphene.ObjectType):
password_set = PasswordSet.Field()
password_change = PasswordChange.Field()
# # django-graphql-jwt inheritances
token_auth = ObtainJSONWebToken.Field()
verify_token = relay.VerifyToken.Field()
refresh_token = relay.RefreshToken.Field()
revoke_token = relay.RevokeToken.Field()
unlock_user = UsuarioUnlock.Field()
class Mutation(AuthRelayMutation, graphene.ObjectType):
user_create = UserCreate.Field()
user_update = UserUpdate.Field()
user_delete = UserDelete.Field()
schema = graphene.Schema(query=Query, mutation=Mutation)
然而,当我测试登录时,仍然会收到消息:“请输入有效的凭据。”我应该如何更改该消息
更新
class ObtainJSONWebToken(
RelayMutationMixin, ObtainJSONWebTokenMixin, graphql_jwt.relay.JSONWebTokenMutation
):
__doc__ = ObtainJSONWebTokenMixin.__doc__
user = graphene.Field(UserNode)
days_remaining = graphene.Field(graphene.String, to=graphene.String())
unarchiving = graphene.Boolean(default_value=False)
@classmethod
def resolve(cls, root, info, **kwargs):
user = info.context.user
# Little logic validations
unarchiving = kwargs.get("unarchiving", False)
return cls(user=info.context.user, days_remaining=days_remaining)
@classmethod
def Field(cls, *args, **kwargs):
cls._meta.arguments["input"]._meta.fields.update(
{"password": graphene.InputField(graphene.String, required=True)}
)
for field in app_settings.LOGIN_ALLOWED_FIELDS:
cls._meta.arguments["input"]._meta.fields.update(
{field: graphene.InputField(graphene.String)}
)
return super(graphql_jwt.relay.JSONWebTokenMutation, cls).Field(*args, **kwargs)
我也遇到了这个问题,但由于
graphql_auth/bases.py
中的django-graphql-auth
库中的this line而意识到,为了使用自定义错误,您必须将settings.py
文件中的类指示为字符串。这似乎为我解决了这个问题例如,我有:
(其中
CustomErrorType
是一个类似于您在原始帖子中指出的类)我也有同样的问题。我找到并引用了这个GitHub线程:https://github.com/flavors/django-graphql-jwt/issues/147 它有点过时,但我对它进行了调整,效果很好:
