Google App Engine 配置端点 API
Google App Engine configuring Endpoints API
我在配置端点时遇到问题 API。我使用的任何代码，从我自己的代码到 google 网站上的示例都失败了，并出现相同的回溯

我的 app.yaml 的配置类似于新的 Endpoints Migrating to 2.0 文档指出：
- url: /_ah/api/.*
script: api.solaris.api_app
并且 main.py 将 API 导入应用程序：
api_app = endpoints.api_server([SolarisAPI,], restricted=False)
我在这些版本中使用 Google Cloud SDK：

您是否尝试过为服务生成和上传 OpenAPI 配置？请参阅名为 "Generating the OpenAPI configuration file" and "Deploying the OpenAPI configuration file" in the python library documentation.
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添加 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权限.
要摆脱 "FrontendsNotSupported"，您需要使用 "B*" 实例 class。
如果您按照 https://cloud.google.com/endpoints/docs/frameworks/python/quickstart-frameworks-python 中的步骤操作，错误 "Exception: Fetching service config failed" 应该会消失。正如 Brad 已经指出的那样，"OpenAPI configuration" 部分和生成的环境变量是使服务配置正常工作所必需的。
