谷歌应用引擎配置端点API

Question

我在配置端点API时遇到问题。我使用的任何代码，从我自己的，到谷歌网站上的例子，都会因为同样的回溯而失败

我的app.yaml的配置与迁移到2.0文档状态的新端点类似：

^{pr2}$

并且main.py将API导入应用程序：

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

要去掉“FrontendsNotSupported”，您需要使用一个“B*”实例类。在

如果按照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，“OpenAPI配置”一节和产生的环境变量是服务配置工作所必需的。在

Answer 2

您是否尝试为服务生成并上载OpenAPI配置？请参阅"Generating the OpenAPI configuration file"和"Deploying the OpenAPI configuration file"中名为"Generating the OpenAPI configuration file"和"Deploying the OpenAPI configuration file"的部分。在

注意，在生成过程的第2步中，您可能需要在命令前面加上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权限。在
