如何验证Google ID令牌？

Question

I want to authenticate Android users with a Go AppEngine backend,

I can easily get an ID-token in Android by following http://android-developers.blogspot.co.il/2013/01/verifying-back-end-calls-from-android.html

how can I verify the token and get the payload ? is there a Go package for this ?

Answer 1

I found the solution myself, the ID-token can be verified with the oauth2/v2 package of the https://code.google.com/p/google-api-go-client/ library.

some installation tweaks are necessary for using it with AppEngine, I found some pointers at http://golangtutorials.blogspot.co.il/2011/11/using-external-api-in-go-appengine.html
