Google-api-ruby-client: ISSUES: Rails google analytics api error

[arjunmenon]

Using the gem'google-api-client', require: 'google/apis/analytics_v3'

However, i am getting this error

ArgumentError in WelcomeController#analytics
Missing token endpoint URI.

(Error highlighted on Analytics method on @account_summaries)

Controller file

class WelcomeController < ApplicationController

    def redirect
      client = Signet::OAuth2::Client.new({
        client_id: 'APP ID',
        client_secret: 'APP SECRET',
        authorization_uri: 'https://accounts.google.com/o/oauth2/auth',
        scope: Google::Apis::AnalyticsV3::AUTH_ANALYTICS_READONLY,
        redirect_uri: url_for(:action => :oauth2callback)
      })

      redirect_to client.authorization_uri.to_s
    end

    def oauth2callback
        client = Signet::OAuth2::Client.new({
        client_id: 'APP ID',
        client_secret: 'APP SECRET',
        token_credential_uri: 'https://accounts.google.com/o/oauth2/token',
        redirect_uri: url_for(:action => :oauth2callback),
        code: params[:code]
      })

      response = client.fetch_access_token!

      session[:access_token] = response['access_token']

      redirect_to url_for(:action => :analytics)

    end

    def analytics
        client = Signet::OAuth2::Client.new(access_token: session[:access_token])

        access_token = Accesstoken.new 'client'

        service = Google::Apis::AnalyticsV3::AnalyticsService.new

        service.authorization = access_token

        @account_summaries = service.list_account_summaries(options: { authorization: client })


    end

end

I did follow an advice stated here - Missing token endpoint URI while using a valid access_token - but this still does not work.

class Accesstoken < ActiveRecord::Base
  attr_reader :token
  def initialize(token)
    @token = token
  end

  def apply!(headers)
    headers['Authorization'] = "Bearer #{@token}"
  end

end

Where is the issue??

Please note -

If in @account_summaries I put in authorization: access_token instead of client, it would then return Unauthorized. What is going on?

The error means exactly that -- you're not configuring the oauth client with enough information.

I suggest using https://github.com/google/google-auth-library-ruby/ instead of signet directly.

@sqrrrl this worked a while ago, and now i get same issue. So something changed.

I'm not using OAuth2 for authentication (I'm using server credentials), but I recently updated the gem after a while and also got the Missing token endpoint URI. error. My solution was to use the #make_creds method.

I changed

Google::Auth::ServiceAccountCredentials.new(
  json_key_io: path_to_json_file,
  scope: ['https://www.googleapis.com/auth/analytics.readonly']
)

to

Google::Auth::ServiceAccountCredentials.make_creds(
  json_key_io: path_to_json_file,
  scope: ['https://www.googleapis.com/auth/analytics.readonly']
)

and everything works fine now.

@arjunmenon Did you get this to work? I've had the exact same problem for 2 days now. Getting "Missing token endpoint URI". @23tux Would you mind showing an example with the rest of the code for that?

You can follow this excellent guide here. This would surely get things started - http://blog.jieck.com/server-side-integrates-google-analytics-api-with-ruby/
