Question

我正在尝试实现一项服务，该服务检查登录用户是否在数据存储上，如果是，则返回True，否则返回False。这是我正在使用的代码：

import endpoints

from google.appengine.ext import ndb
from protorpc import remote
from protorpc import messages

from endpoints_proto_datastore.ndb import EndpointsModel
from google.appengine.api import users

class AuthRes(messages.Message):
    message = messages.StringField(1)

class UserModel(EndpointsModel):
    user = ndb.UserProperty()

@endpoints.api(name='myapi', version='v1', description='My Little API')
class MyApi(remote.Service):

    @UserModel.method(path='myuser', http_method='GET', name='myuser.check')
    def UserCheck(self, cls):
        user = users.get_current_user()
        if user:
            myuser = cls.query().filter(cls.user.user_id() == user.user_id()).get()
            if not myuser:
                  return AuthRes(message="False")
            else:
                  return AuthRes(message="True")
        else:
            return AuthRes(message="False")


application = endpoints.api_server([MyApi], restricted=False)

我总是得到'AuthRes' object has no attribute 'ToMessage'

我相信而不是：

@UserModel.method(path='myuser', http_method='GET', name='myuser.check')

你想要这个：

from protorpc import message_types  # add at the top

@endpoints.method(message_types.VoidMessage, AuthRes, path='myuser', http_method='GET', name='myuser.check')

Google应用引擎：对象没有属性ToMessage
