V2多类API错误应用程序引擎标准

Question

错误： ApiConfigurationError:试图用不兼容的多个类实现服务回送，版本v2。有关如何实现多类API的示例，请参见docstring ()。

代码：

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])

好消息: version='v1‘(EchoApi)

错误if: version='v2‘被添加(EchoApi2)

错误代码: ApiConfigurationError:尝试用不兼容的多个类实现v2版本的服务回显。有关如何实现多类API的示例，请参见docstring ()。

谢谢。

这是创建使用多个类实现的API的正确格式：

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])
