Google API Python 客户端 ( http://code.google.com/p/google-api-python-client/ ) 有一个示例应用程序在 Google App Engine 基础架构上演示 OAUTH2。这可以在以下位置找到：
http://code.google.com/p/google-api-python-client/source/browse/#hg%2Fsamples%2Fappengine
我试着抓住这个例子，用我的应用程序的凭据填写 client_secrets.json，但使用本地 dev_appserver 运行我得到：

当我使用 appcfg.py 在 GAE 上实时部署应用程序时，当我转到应用程序的根页面时，我收到 500 服务器错误，并且开发控制台日志显示：

所以嗯，救命？
FWIW，我确实按照将整个客户端代码复制到应用程序引擎项目的说明进行操作（如http://code.google.com/p/google-api-python-client/wiki/GoogleAppEngine中所述）
