是否可以在谷歌应用引擎上将马提尼的 sessionauth 与 Datastore 一起使用？

Question

我尝试在google app engine上使用martini的sessionauth的例子，想在Datastore中保存登录列表，但不知道如何处理appengine.Context。有人有经验吗？

谢谢。

是的，应该可以。 sessionauth 包需要你传递一个*sessions.Store，并且有一个可以替换默认cookie/文件存储的gaesessions 包：https://github.com/hnakamur/gaesessions

sessionauth 包有一个完整的示例 (https://github.com/martini-contrib/sessionauth/blob/master/example/auth_example.go) - 只需将 sessions.NewCookieStore 替换为 gaesessions.NewDatastoreStore。
