Google Cloud Endpoints V2多類API錯誤App Engine標准

Question

錯誤： ApiConfigurationError：嘗試使用多個不兼容的類來實現版本2的服務回顯。 有關如何實現多類API的示例，請參見api（）的docstring。

碼：

import logging
import endpoints
from protorpc import message_types
from protorpc import messages
from protorpc import remote

class EchoRequest(messages.Message):
   content = messages.StringField(1)

class EchoResponse(messages.Message):
    content = messages.StringField(1)

ECHO_RESOURCE = endpoints.ResourceContainer(
    EchoRequest, n=messages.IntegerField(2, default=1))

@endpoints.api(name='echo', version='v1',description='description')
class EchoApi(remote.Service):

  @endpoints.method(
    # This method takes a ResourceContainer defined above.
    ECHO_RESOURCE,
    # This method returns an Echo message.
    EchoResponse,
    path='echo',
    http_method='POST',
    name='echo')

  def echo(self, request):
    logging.info("echo1"+ str(request.content))
    output_content = ' '.join([request.content] * request.n)
    return EchoResponse(content=output_content)

@endpoints.api(name='echo', version='v2', description='description2')
class EchoApi2(remote.Service):

  @endpoints.method(
    # This method takes a ResourceContainer defined above.
    ECHO_RESOURCE,
    # This method returns an Echo message.
    EchoResponse,
    path='echo',
    http_method='POST',
    name='echo')

  def echo(self, request):
    logging.info("echo2" + str(request.content))
    output_content = ' '.join([request.content] * request.n)
    return EchoResponse(content=output_content)

api = endpoints.api_server([EchoApi, EchoApi2])

如果只有，則表示良好：version ='v1'（EchoApi）

如果出現以下錯誤：添加版本='v2'（EchoApi2）

錯誤代碼：ApiConfigurationError：嘗試使用多個不兼容的類來實現版本2的服務回顯。 有關如何實現多類API的示例，請參見api（）的docstring。

謝謝。

這是用於創建由多個類實現的API的正確格式：

import logging
import endpoints
from protorpc import message_types
from protorpc import messages
from protorpc import remote

class EchoRequest(messages.Message):
   content = messages.StringField(1)

class EchoResponse(messages.Message):
    content = messages.StringField(1)

ECHO_RESOURCE = endpoints.ResourceContainer(
    EchoRequest, n=messages.IntegerField(2, default=1))

echo_collection = endpoints.api(name='echo', version='v1', description='description')

@echo_collection.api_class(resource_name='echo1')
class EchoApi1(remote.Service):

  @endpoints.method(
    # This method takes a ResourceContainer defined above.
    ECHO_RESOURCE,
    # This method returns an Echo message.
    EchoResponse,
    path='echo',
    http_method='POST',
    name='echo')

  def echo(self, request):
    logging.info("echo1"+ str(request.content))
    output_content = ' '.join([request.content] * request.n)
    return EchoResponse(content=output_content)

@echo_collection.api_class(resource_name='echo2')
class EchoApi2(remote.Service):

  @endpoints.method(
    # This method takes a ResourceContainer defined above.
    ECHO_RESOURCE,
    # This method returns an Echo message.
    EchoResponse,
    path='echo',
    http_method='POST',
    name='echo')

  def echo(self, request):
    logging.info("echo2" + str(request.content))
    output_content = ' '.join([request.content] * request.n)
    return EchoResponse(content=output_content)

api = endpoints.api_server([echo_collection])
