google-app-engine - 可以在Google App Engine上将Martini的sessionauth与Datastore一起使用吗？

我尝试在Google App Engine上使用sessionauth的martini的示例，并希望将登录列表保存在数据存储区中，但不知道如何处理appengine.Context。有没有人有经验？

谢谢你。

最佳答案

是的，应该有可能。 sessionauth软件包要求您向其传递*sessions.Store，并且有一个gaesessions软件包可以替换默认的cookie/文件存储:https://github.com/hnakamur/gaesessions

sessionauth软件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即可。
