Question

配置端點API時遇到問題。我使用，從我自己的，谷歌的例子在現場的任何代碼失敗，相同的回溯

我app.yaml配置像新端點遷移到2.0文件規定：

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

而且main.py進口該API到應用程序：

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

我使用谷歌雲SDK與這些版本：

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

要擺脫「FrontendsNotSupported」，您需要使用「B *」實例類。

如果您按照https://cloud.google.com/endpoints/docs/frameworks/python/quickstart-frameworks-python中的步驟操作，則應該消除「異常：獲取服務配置失敗」錯誤。正如Brad已經指出的那樣，需要「OpenAPI配置」部分和生成的環境變量來使服務配置生效。

Answer 2

您是否嘗試過生成並上傳服務的OpenAPI配置？請參閱python library documentation中名爲"Generating the OpenAPI configuration file"和"Deploying the OpenAPI configuration file"的部分。

請注意，在生成過程的第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 ...），因爲PyPi包現在不保留可執行文件許可權。
