Is it possible to use sessionauth of martini with Datastore on google app engine?

问题

我尝试在Google App Engine上使用martinisessionauth示例,并希望将登录列表保存在Datastore中,但不知道如何处理appengine.Context。有人有经验吗?

谢谢。

I tried to use the example of sessionauth of martini on google app engine and want to save login list in Datastore, but did not know how to deal with appengine.Context. Does anyone has the experience?

Thank you.

得分: 1

是的,这应该是可能的。sessionauth包要求你传递一个*sessions.Store,而有一个gaesessions包可以替代默认的cookie/file存储: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

英文:

Yes, it should be possible. The sessionauth package requires you to pass it a *sessions.Store, and there is a gaesessions package that can replace the default cookie/file stores: https://github.com/hnakamur/gaesessions

The sessionauth package has a full example (https://github.com/martini-contrib/sessionauth/blob/master/example/auth_example.go) - just replace sessions.NewCookieStore with gaesessions.NewDatastoreStore.
