不工作示例基本

Question

我正在使用 Google Endpoints 和 http://endpoints-proto-datastore.appspot.com/ 中的 endpoints-proto-datastore 的基本示例

这是我的文件 widgettiny_api.py

import endpoints

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

from endpoints_proto_datastore.ndb import EndpointsModel



class Noticia(EndpointsModel):
    _message_fields_schema = ('id', 'titulo', 'contenido', 'creado')

    titulo = ndb.StringProperty()
    contenido = ndb.StringProperty()
    url_imagen = ndb.StringProperty()
    url = ndb.StringProperty()
    creado = ndb.DateTimeProperty(auto_now_add=True)


@endpoints.api(
    name='WidgetTinyApi',
    version='v1',
    description='API usada para consumir las noticias desde el cliente android o widget.')
class WidgetTinyApi(remote.Service):

    @Noticia.method(
        path="noticia",
        http_method="POST",
        name="noticia.insert")
    def NoticiaInsert(self, my_model):
        my_model.put()
        return my_model


    @Noticia.method(
        request_fields=('id',),
        path='noticia/{id}',
        http_method='GET',
        name='noticia.get')
    def NoticiaGet(self, my_model):
        if not my_model.from_datastore:
            raise endpoints.NotFoundException('Noticia no encontrada')
        return my_model


    @Noticia.query_method(
        path="noticias",
        name="noticia.list")
    def NoticiaList(self, query):
        return query


APPLICATION = endpoints.api_server([WidgetTinyApi], restricted=False)

我打开链接 /_ah/api/explorer 。我得到这个错误：

什么是错误？

Answer 1

name='WidgetTinyApi' 无效。你需要一个小写的值。

来自documentation：

名称值：

• 必须以小写字母开头。
• 必须匹配正则表达式[a-z]+[A-Za-z0-9]*。

Answer 2

我在实施过程中遇到了同样的错误。我检查了 API 的名称是否与正则表达式匹配，并且它以小写字符开头。

正如@0xAffe 评论的那样，我检查了版本号是“v1”。

这是我的代码：

import logging
import endpoints
from models.inmobiliaria import SalesExecutive
from protorpc import remote


@endpoints.api(name='juustoRestApi',
               version='v1',
               description='Enpoints API for the Juus.to app')
class JuustoRestApi(remote.Service):

    @SalesExecutive.method(path='executive/create',
                           http_method='POST',
                           name='executive.create')
    def create_sales_executive(self, executive):
        executive.put()
        return executive

    @SalesExecutive.query_method(query_fields=('email', 'password'),
                                               path='executive/login',
                                               name='executive.login')
    def login(self, query):
        logging.info(query)
        return query

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