问题
I try move canvas-app to v2.1 api. So when an user are authorizing to the app I send
[protocol://]graph.facebook.com/v2.1/oauth/authorize?client_id=XXXX&scope=&redirect_uri=XXXXX
and got redirect to
[protoco://]www.facebook.com/dialog/oauth?client_id=XXXX&scope=&redirect_uri=XXXXX
which is dialog from API version 1
I expect to get dialog API version 2.1
[protocol://]www.facebook.com/v2.1/dialog/oauth?client_id=XXXX&scope=&redirect_uri=XXXXX
how can I reach it?
回答1:
We were stumped on this and then we checked our App Settings, under Migrations, and this problem went away when we turned on "Use Graph API v2.0 by default". Hope that helps.

We encountered the same issue. We fixed it by just linking directly to the new URL:
https://www.facebook.com/v2.1/dialog/oauth?client_id=XXXX&scope=&redirect_uri=XXXXX
