I am using google-api-client gem to post message to google plus when a user logs in my application with his google plus credentials.
Below is my code.
require 'google/api_client'
require 'google/api_client/client_secrets'
require 'google/api_client/auth/installed_app'
keypath = Rails.root.join('config','poo-02a507f45ab4.p12').to_s
key = Google::APIClient::KeyUtils.load_from_pkcs12(keypath, 'notasecret')
client = Google::APIClient.new(
:application_name => 'my app',
:application_version => '1.0.0'
)
urlshortener = client.discovered_api('urlshortener', 'v1')
client.authorization = Signet::OAuth2::Client.new(
:token_credential_uri => 'https://accounts.google.com/o/oauth2/token',
:audience => 'https://accounts.google.com/o/oauth2/token',
:scope => ['https://www.googleapis.com/auth/prediction','https://www.googleapis.com/auth/plus.stream.write','https://www.googleapis.com/auth/plus.login','https://www.googleapis.com/auth/urlshortener','https://www.googleapis.com/auth/plus.circles.write'],
:issuer => 'id#developer.gserviceaccount.com',
:signing_key => key)
client.authorization.fetch_access_token!
batch = Google::APIClient::BatchRequest.new do |result|
puts result.data
end
batch.add(:api_method => urlshortener.url.insert,:body_object => { 'longUrl' => 'https://www.facebook.co.in' })
client.execute(batch)
While trying this code its giving below error.
{\n \"domain\": \"usageLimits\",\n \"reason\": \"accessNotConfigured\",\n \"message\": \"Access Not Configured. The API is not enabled for your project, or there is a per-IP or per-Referer restriction configured on your API key and the request does not match these restrictions. Please use the Google Developers Console to update your configuration.\",\n
I have enabled google + API and contacts API in developers console.
Please help me to solve this problem.
The problem you are having is that you are using a service account.
The Google OAuth 2.0 system supports server-to-server interactions such as those between a web application and a Google service. This scenario is called a service account, which is an account that belongs to your application instead of to an individual end user. Your application calls Google APIs on behalf of the service account, so users aren't directly involved.
If you want to post on behalf of a user you will need to be using Oauth2, then you will be able to authenticate the user.
Update:
So that you are aware it is not possible to post to a users Google+ time line. the best you can do is post something called moments which isn't really the same thing. An issue request was made for this in 2011 I think they have yet to add this feature.

I have successfully integrated Quickbook accounting APIs with the Development Keys and Credentials. Moreover, when I put Production Keys and Secret, I got an error with status code (403), and later I got to know that is because of scopes.
I noticed there is a function called "getScope()" to check the token scopes. I went to try that and get the following error:
Can't get OAuth 2 Scope. It is not set.
I even tried using access and refresh tokens from the API playground. Still, the error is there.
Here is my code snippet:
$dataService = DataService::Configure(array(
'auth_mode' => 'oauth2',
'ClientID' => $quickBookData->client_id,
'ClientSecret' => $quickBookData->client_secret,
'accessTokenKey' => $quickBookData->access_token,
'refreshTokenKey' => $quickBookData->refresh_token,
'QBORealmID' => $quickBookData->realm_id,
'baseUrl' => "production",
));
$OAuth2LoginHelper = $dataService->getOAuth2LoginHelper();
$scopes = $OAuth2LoginHelper->getScope();
I've a problem with authenticating Google account with my Rails app.
I'm using omniauth-google-oauth2 gem with Devise.
Always get this Error when I try to access google account:
Error: redirect_uri_mismatch
The redirect URI in the request: http://localhost:3000/users/auth/google_oauth2/callback did not match a registered redirect URI
I'm sure that the registered redirect URI in my google console app is right and identical with requested one, just like that:
so what's main the problem here?
try this way :
add require "omniauth-google-oauth2" to devise.rb in config/initializers folder
add http://localhost:3000/users/auth/google_oauth2/callback into Redirect URL in google API console https://console.developers.google.com
restart server
Mine solution is to force redirect_url in both (code/token) stages, devise.rb initializer:
CALLBACK_URL = 'https://SOMESERVER/users/auth/google_oauth2/callback'
Devise.setup do |config|
config.omniauth :google_oauth2,
"SOMECLIENTID.apps.googleusercontent.com",
"SOMEKEY",
{
:client_options => {:ssl => {:ca_file => 'C:\Ruby21\cacert.pem'}},
:provider_ignores_state => true,
:prompt => "select_account",
:redirect_uri => CALLBACK_URL,
setup: (lambda do |env|
request = Rack::Request.new(env)
env['omniauth.strategy'].options['token_params'] = {:redirect_uri => CALLBACK_URL}
end)
}
end
there is discussion about the issue here: https://github.com/zquestz/omniauth-google-oauth2/issues/181
Be careful of what client id you are setting.
Google API provides two:
Client ID for Google Compute and App Engine
Client ID for web applications
You need to use Client ID for web applications
Make sure you set up the Product Name and Email address via the Consent Screen Link.
Per the omniauth-google-oauth2 documentation you need to:
Go to 'https://console.developers.google.com'
Select your project.
Click 'APIs & auth'
Make sure "Contacts API" and "Google+ API" are on.
Go to Consent Screen, and provide a 'PRODUCT NAME'
Wait 10 minutes for changes to take effect.
I had the same issue, made the updates, waited 10 minutes, still nothing, went to lunch, then it started to work. Guess patience was part of the key to success on this one.
I want to get contact from Google Plus.
I am using
gem "omniauth"
gem "omniauth-google-oauth2"
for authentication and
gem "google-api-client"
for comunicate with google apis.
So far authentication is working fine and I got access_token after authentication.
Now problem is I couldn't find a way to get list of people in my circle (My Google Plus Contact).
Is there any way to do this.
Specifically I need to know is there any gem more like "fb_graph" for google?
I found this trick
https://plus.google.com/u/0/_/socialgraph/lookup/visible/o=%5Bnull%2Cnull%2C%22_UID_%22%5D&rt=j
Just need to put "UID" and you can get contacts in your circle but their name and ID only. But I need more information...
WorkFlow
client = Google::APIClient.new
client.authorization.client_id = GOOGLE_CONFIG[:app_id]
client.authorization.client_secret = GOOGLE_CONFIG[:app_secret]
client.authorization.access_token = token
plus = client.discovered_api('plus')
data = client.execute( plus.people.list, :collection => 'connected', :userId => 'me').data
In data I get this message
<Google::APIClient::Schema::Plus::V1::PeopleFeed:0x6569248 DATA:{"error"=>{"errors"=>[{"domain"=>"global", "reason"=>"insufficientPermissions", "message"=>"Insufficient Permission"}], "code"=>403, "message"=>"Insufficient Permission"}}>
I found similar problem here but solution is still needs to be find out.
I need to add Scope in devise initializers and then by auth token everything seems to be working perfectly.
scope: "https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/plus.me https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile"
OR Add this line
config.omniauth :google_oauth2, GOOGLE_CONFIG[:app_id], GOOGLE_CONFIG[:app_secret],{ access_type: "offline", approval_prompt: "force", scope: 'https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/plus.me https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile', name: 'google'}
I am using Rails + Garb Gem (Sija Branch) + omniauth-google-oauth2 Gem and I can successfully authenticate with the Google Analytics API and extract data that our app is generating when using a user login, e.g.:
Garb::Session.login('USERNAME', '<PASSWORD>')
I can then use Garb to connect to the Analytics Profile I want and pull the data from it and display some charts on a webpage. This all works fine.
However, I want to use oAuth2 to authenticate with Analytics which is why I had to install the Sija branch of the Garb Gem from Github (it supports oAuth2) and I also installed the omniauth-google-oauth2 Gem. Now in theory I should be able to authenticate using the following code:
Garb::Session.access_token = access_token # an instance of OAuth2::Client
It's at this point that it gets a little hazy for me and I would greatly appreciate some guidance. Here's how far I have gotten:
1) I created a Project in the Google API console and turned on Analytics API under Services
2) This provided me with a Client ID and Client Secret
3) I came across this code which I could populate with the ID and Secret above:
client = OAuth2::Client.new(
GOOGLE_CLIENT_ID,
GOOGLE_CLIENT_SECRET,
{
:site => 'https://accounts.google.com',
:authorize_url => '/o/oauth2/auth',
:token_url => '/o/oauth2/token'
})
4) Then there is the next bit of code:
response = OAuth2::AccessToken.new(
client,
STORED_TOKEN, {
refresh_token: STORED_REFRESH_TOKEN,
expires_at: STORED_EXPIRES_AT
})
5) and then in theory connect with:
Garb::Session.access_token = response
The problem I have is I don't have the token information in Point (4) above. It seems to me that with oAuth2 I need to do a "handshake" once and print out the return token values? Perhaps through Rails code which prints the values returned out and then paste the token values into a constant in the Rails app so that I can use them in the above code? I really am confused. As I mentioned earlier, the web app works fine using the user login authentication. All the web app is doing is authenticating with analytics, pulling down some data and drawing a chart. But I am stuck converting it over to oAuth2 as I just do not know how to get the Access Token that the Garb Gem is looking for. I should also note that this is not a public website with multiple users authenticating, this is a CMS website that is connecting to our own Analytics data.
I have seen some partial snippets of aspects of this but not a fully explained or working example. I would really appreciate any guidance and help with this question.
Many thanks in advance,
JR
I've soldiered through this over the last few weeks, so let me share what worked:
To use Oauth2 you need to get a 'refresh token' that you use to 're-authenticate' with google each time you make an API call. The steps for this are as follows:
1) Setup your account in the API console - https://code.google.com/apis/console/b/0/ (seems like you've done that well)
2) In your API account, make sure you have a redirect URI pointing back to your application:
http://some-url.com/auth/google_oauth2/callback
http://localhost:3000/auth/google_oauth2/callback
Note here that google won't let you call back to your local machine as 0.0.0.0:3000... so you'll need to use localhost explicitly
3) In your route file, tie that redirect url to an action in the controller where you're going to create the project or authentication
match '/auth/:provider/callback' => 'authentications#create'
The ':provider' simply lets you match on multiple types of oauth, but you could just put 'google_oauth2' there as well.
4) Now create that action in your controller
def create
auth = request.env["omniauth.auth"]
params = request.env["omniauth.params"]
project = Project.find(params['project_id'])
Authentication.create(:project_id => project.id, :provider => auth['provider'], :uid => auth['uid'], :access_token => auth['credentials']['refresh_token'])
flash[:notice] = "Authentication successful."
redirect_to owner_view_project_path(project)
end
5) The controller action should retrieve the relevant fields from the response object (details of response object here: https://github.com/zquestz/omniauth-google-oauth2) - in particular, you need to get the 'refresh_token' and save that to your project or authentication object - if you haven't added an 'access_token' attribute to the desired object, go do that now with a migration, then start saving the refresh token to that attribute
6) Now when you're ready to call that particular authentication and get API data for it, you can load up that object where you saved the access token, and use that to get a new session with the google API as follows:
#authentication = Authentications.find(params[:id])
client = OAuth2::Client.new GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET,
{
:site => 'https://accounts.google.com',
:authorize_url => "/o/oauth2/auth",
:token_url => "/o/oauth2/token",
}
response = OAuth2::AccessToken.from_hash(client, :refresh_token => #authentication.access_token).refresh!
Garb::Session.access_token = response
#profiles = Garb::Management::Profile.all
What this code did was create an OAuth2 access token (response) by specifying the client and then a refresh_token, then calling 'refresh!' to get a refreshed access token... then use that access token to establish your Garb session, then call down all the profiles for a given account using the Gard::Management::Profile.all
Hope this helps - let me know if you have questions!
Just a note on what worked for me in:
For steps 3, 4 & 5 I used cURL instead to retrieve the Access/Refresh token. Step 6 is then the same for me (using the Sija branch of the Garb Gem). So using cURL:
Using the details associated with your Google app POST the following using cURL:
curl --data "code=<APP_CODE>&redirect_uri=http://localhost:3000/oauth2callback&client_id=<CLIENT_ID>.apps.googleusercontent.com&scope=&client_secret=<CLIENT_SECRET>&grant_type=authorization_code" https://accounts.google.com/o/oauth2/token
The response takes the form:
{
"access_token" : "<ACCESS_TOKEN>",
"token_type" : "Bearer",
"expires_in" : 3600,
"refresh_token" : "<REFRESH_TOKEN>"
}
which you can plug into the Garb Gem as per part 6.
The answer by #CamNorgate is valid.
If you don't have a "refresh_token" back from Omniauth on the callback make sure you are correctly initializing :google_oauth2
Rails.application.config.middleware.use OmniAuth::Builder do
provider :google_oauth2, ENV["GOOGLE_CLIENT_ID"], ENV["GOOGLE_CLIENT_SECRET"],
{ :scope=>"https://www.google.com/m8/feeds, https://www.googleapis.com/auth/userinfo.email, https://www.googleapis.com/auth/userinfo.profile",
:approval_prompt=>"force", access_type="offline"
}
end
Make sure to include :approval_prompt=>"force", access_type="offline" in order for the refresh_token to be sent back. The refresh_token is only provided on the first authorization from the user.
I'm trying to use OAuth2 for Server to Server Applications in conjunction with Google's Content API for Shopping using the google-api-client gem and Ruby on Rails 3.2.5. Also, I have already set up my merchant account as prescribed in the Content API documentation.
This was the best way I found to be able to:
create/update products in the background
have created products fall under my company's Google Products 'umbrella'
not require every user to authenticate/authorize when their token expires
Using lines 1 - 23 from this sample as a starting point, I've begun to write the following module for use in background jobs:
require 'httparty'
require 'google/api_client'
module GoogleProducts
GOOGLE_CONFIG = YAML.load_file(File.join(Rails.root, "config", "google.yml"))[Rails.env]
CLIENT_ID = "XXXXXXXXXXXX#developer.gserviceaccount.com"
MERCHANT_ID = "XXXXXXX"
SCOPE = "https://www.googleapis.com/auth/structuredcontent"
KEY_FILE_PATH = File.join(Rails.root, "config", "my-privatekey.p12")
KEY_FILE_PASS = "XXXXXXXXXX"
def self.add_item(item_id)
self.fetch_token
xml = self.gen_item_xml(item_id)
headers = {"Content-type" => "application/atom+xml", "Content-Length" => xml.length.to_s}
url = "https://content.googleapis.com/content/v1/#{MERCHANT_ID}/items/products/generic?access_token=#{$gp_token}"
response = HTTParty.post(url, :body => xml, :headers => headers).parsed_response
end
def self.gen_item_xml(item_id)
#building product xml
end
private
def self.fetch_token
api_client = Google::APIClient.new(:authorization => :oauth2)
key = Google::APIClient::PKCS12.load_key(KEY_FILE_PATH, KEY_FILE_PASS)
asserter = Google::APIClient::JWTAsserter.new(CLIENT_ID, SCOPE, key)
begin
api_client.authorization = asserter.authorize
#todo - store in something other than a global
$gp_token = api_client.authorization.access_token
rescue Signet::AuthorizationError => e
puts e.message
ensure
return $gp_token
end
end
end
Everything seemingly works fine - the authentication, the handling of the auth token - until I attempt to actually add an item, which I get the following when I do:
<errors xmlns='http://schemas.google.com/g/2005'>
<error>
<domain>GData</domain>
<code>ServiceForbiddenException</code>
<internalReason>Could not find authenticated customer</internalReason>
</error>
</errors>
Any ideas?
After much anguish and mental toil, I've finally solved my issue!
Since I am using OAuth 2 Server to Server authentication the suggestion hjblok gave didn't apply (thanks for giving it a shot, though!).
I simply added the email address that was associated with my Service Account key from the Google API Console (e.g. XXXXXXXXXXXX#developer.gserviceaccount.com) to my Google Merchant account (Settings > Users on the merchant admin page), and it worked.
If there's any clarification needed, please feel free to comment!
The Google Content API documentation says you need to set it up in the Settings page of the Google Merchant Center:
https://developers.google.com/shopping-content/getting-started/usingapi-products
EDIT rewrote the answer after diving into the Google's API documentation
Did you already try to use Google's OAuth 2.0 playground? I was able to successfully access https://content.googleapis.com/content/v1/#{MERCHANT_ID}/items/products/generic.
In "Step 1" I've chosen the "Content API for Shopping" and then authorized the API with my account.
Then in "Step 2" I've "exchanged authorization code for tokens", which results in a "refresh token" and an "access token".
Then in "Step 3" I've invoked a GET request to https://content.googleapis.com/content/v1/1234567/items/products/generic. Because 1234567 is not a valid MERCHANT_ID it returns an Error. But the Error Messages contains a MERCHANT_ID which actually belongs to your account.
I repeated "Step 3" but now with the correct MERCHANT_ID. Which returns a HTTP/1.1 200 OK with the requested items in the body.
Furthermore I'm not sure, but doesn't Google API expect an Authorization header to be present with the access_token ($gp_token)? Within the OAuth 2.0 playground this Authorization header is used to sent the access_token.
I also found the Structured Content API demo page (https://google-content-api-tools.appspot.com/demo/demo.html), which is more specific to the Content API for Shopping.
