google-app-engine - 简单的 Google Cloud Endpoints 应用

Question

经过 2 多天的尝试弄清楚如何使它工作，我现在要寻求帮助。这只是一个简单的应用程序，只是为了让 Google Cloud Endpoints 工作。它部署良好，但实际上无法正常工作。很难调试，因为没有错误消息可以解决。这是我的代码：

应用程序.yaml

application: [my-simple-api]
version: 1
runtime: python27
threadsafe: true
api_version: 1

handlers:
- url: /_ah/spi/.*
  script: main.application

libraries:
- name: endpoints
  version: "1.0"

主文件

#should this be "from google.appengine.ext import endpoints"?
import endpoints
from protorpc import messages
from protorpc import message_types
from protorpc import remote

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

@endpoints.api(name='simple', version='v1')
class SimpleApi(remote.Service):

    @endpoints.method(message_types.VoidMessage, SimpleMessage, path='simpleget', http_method='GET', name='simple.get')
    def simple_get(self, unused_request):
        return SimpleMessage(message="hello this is a simple api")

application = endpoints.api_server([SimpleApi])
