我的解决方案是：
创建decorators.py文件

from functools import wraps
from graphql import GraphQLError
from api.utils import snake_to_camel_case

def private_field(func):
    @wraps(func)
    def wrapper(self, info):
        user = info.context.user

        if user.id != self.id:
            field_name = func.__name__.replace('resolve_', '')
            field_name_camel_cased = snake_to_camel_case(field_name)
            raise GraphQLError(f'You do not have permissions to access {field_name}')
        
        return func(self, info)
    return wrapper

字符串
snake_to_camel_case函数：

def snake_to_camel_case(string):
    components = string.split('_')
    return components[0] + ''.join(x.title() for x in components[1:])

型
最后在我的模式文件解析器上：

@private_field
    def resolve_private_field(self, info):
        return self.private_field

型
响应应该是这样的：

{
    "errors": [
        {
            "message": "You do not have permissions to access privateField",
...

型
现在显然这个解决方案是超级具体为我的需要atm但它应该很容易足够使它更通用和可扩展的任何情况。
