connect/authenticate with google using grails oauth plugin - grails

Question

I am trying to connect with Google using the grails oauth plugin. Following is my code
Config.groovy
oauth {
providers {
google {
api = org.scribe.builder.api.GoogleApi
key = 'XXX.apps.googleusercontent.com'
secret = 'XXXXXXX'
scope = 'https://www.googleapis.com/auth/userinfo.profile'
callback = "${grails.serverURL}/oauth/google/callback"
successUri = "${grails.serverURL}/oauthCallBack/google"
}
}
}
grails.google.api.url = "https://accounts.google.com/o/oauth2/auth"
OauthCallBackController.groovy
class OauthCallBackController {
def oauthService
def google() {
Token googleAccessToken = (Token) session[oauthService.findSessionKeyForAccessToken('google')]
def googleResource = oauthService.getGoogleResource(googleAccessToken, grailsApplication.config.grails.google.api.url)
def googleResponse = JSON.parse(googleResource?.getBody())
log.info "googleAccessToken = ${googleAccessToken}"
log.info "googleResponse = ${googleResponse}"
log.info "accesstoken = ${googleAccessToken.token}"
def googleResourceDetailed = oauthService.getGoogleResource(googleAccessToken, "https://www.googleapis.com/oauth2/v1/userinfo?access_token=${googleAccessToken.token}")
def googleResponseDetailed = JSON.parse(googleResourceDetailed?.getBody())
log.info "googleResourceDetailed = ${googleResourceDetailed}"
log.info "googleResponseDetailed = ${googleResponseDetailed}"
render params
}
}
When I trying to connect, google ask me to allow the application to access my credentials. After allowing my call back action executed(oauthCallBack/google) but I am not getting the data of my account.
Following is my output in my logs
INFO example.OauthCallBackController - googleAccessToken = Token[1/xxx , yyy]
INFO example.OauthCallBackController - googleResponse = [:]
INFO example.OauthCallBackController - accesstoken = 1/xxx
INFO example.OauthCallBackController - googleResourceDetailed = org.scribe.model.Response#2a088ca
INFO example.OauthCallBackController - googleResponseDetailed = [error:[message:Invalid Credentials, errors:[[message:Invalid Credentials, location:Authorization, reason:authError, locationType:header, domain:global]], code:401]]
I have no idea where I am wrong and why I am getting the error as response.
How can I get data from google?

Answer 1

Finally..,.
After lots of google search I finally figure out my problem and successfully got data from google.
The problem is in my grails.google.api.url entry in my config file.
Correct value is
grails.google.api.url = "https://www.googleapis.com/oauth2/v1/userinfo"
Now my code is
Config.groovy
oauth {
providers {
google {
api = org.scribe.builder.api.GoogleApi
key = 'XXX.apps.googleusercontent.com'
secret = 'XXXXXXX'
scope = 'https://www.googleapis.com/auth/userinfo.profile'
callback = "${grails.serverURL}/oauth/google/callback"
successUri = "${grails.serverURL}/oauthCallBack/google"
}
}
}
grails.google.api.url = "https://www.googleapis.com/oauth2/v1/userinfo"
OauthCallBackController.groovy
def google() {
Token googleAccessToken = (Token) session[oauthService.findSessionKeyForAccessToken('google')]
def googleResource = oauthService.getGoogleResource(googleAccessToken, grailsApplication.config.grails.google.api.url)
def googleResponse = JSON.parse(googleResource?.getBody())
log.info "googleAccessToken = ${googleAccessToken}"
log.info "googleResponse = ${googleResponse}"
log.info "accesstoken = ${googleAccessToken.token}"
log.info "id = ${googleResponse.id}"
log.info "name = ${googleResponse.name}"
render params
}
And my log out put is
INFO example.OauthCallBackController - googleAccessToken = Token[1/xxx , yyy]
INFO example.OauthCallBackController - googleResponse = [id:xxxxx, locale:en, link:yyyyy, name:MKB, gender:male, family_name:B, given_name:M]
INFO example.OauthCallBackController - accesstoken = 1/xxx
INFO example.OauthCallBackController - id = xxxxx
INFO example.OauthCallBackController - name = MKB
