Question

配置端点API时遇到问题。我使用，从我自己的，谷歌的例子在现场的任何代码失败，相同的回溯

我app.yaml配置像新端点迁移到2.0文件规定：

- url: /_ah/api/.* 
    script: api.solaris.api_app 

而且main.py进口该API到应用程序：

api_app = endpoints.api_server([SolarisAPI,], restricted=False) 

我使用谷歌云SDK与这些版本：

Google Cloud SDK 132.0.0 
app-engine-python 1.9.40 
bq 2.0.24 
bq-nix 2.0.24 
core 2016.10.24 
core-nix 2016.10.24 
gcloud 
gsutil 4.22 
gsutil-nix 4.22 

Answer 1

要摆脱“FrontendsNotSupported”，您需要使用“B *”实例类。

如果您按照https://cloud.google.com/endpoints/docs/frameworks/python/quickstart-frameworks-python中的步骤操作，则应该消除“异常：获取服务配置失败”错误。正如Brad已经指出的那样，需要“OpenAPI配置”部分和生成的环境变量来使服务配置生效。

Answer 2

您是否尝试过生成并上传服务的OpenAPI配置？请参阅python library documentation中名为"Generating the OpenAPI configuration file"和"Deploying the OpenAPI configuration file"的部分。

请注意，在生成过程的第2步中，您可能需要在命令前加上python（例如python lib/endpoints/endpointscfg.py get_swagger_spec ...），因为PyPi包现在不保留可执行文件许可权。
