Google App Engine配置端點API

Question

我在配置Endpoints API時遇到問題。 我使用的任何代碼（無論是我自己的還是現場使用的google示例）均會以相同的追溯失敗

我的app.yaml的配置類似於新的端點遷移到2.0文檔狀態：

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

然后main.py將API導入到應用中：

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

我在以下版本中使用Google Cloud SDK：

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

您是否嘗試過為服務生成和上傳OpenAPI配置？ 請參閱python庫文檔中名為“生成OpenAPI配置文件”和“部署OpenAPI配置文件”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 ... ），因為PyPi包目前不保留可執行文件權限。

Answer 2

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中的步驟進行操作，則錯誤“異常：獲取服務配置失敗”錯誤應該消失了。 正如Brad所指出的那樣，“ OpenAPI配置”部分和生成的環境變量是使服務配置正常工作所必需的。
