Google Cloud Endpoints V2多类API错误App引擎标准

Question

错误： ApiConfigurationError：尝试使用多个不兼容的类实现服务回显版本v2。有关示例，请参阅api（）的docstring以了解如何实现多类API。

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]) 

GOOD如果只有：版本= 'V1'（EchoApi）

如果

ERROR：版本= 'V2' 增加（EchoApi2）

ERROR CODE ：ApiConfigurationError：尝试使用不兼容的多个类实现服务回显版本v2。有关示例，请参阅api（）的docstring以了解如何实现多类API。

谢谢。

这是创建多类实现的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])
