Shopify API App Proxy with Rails verify Users - ruby-on-rails

I am trying to configure an app proxy so users can submit a product for a Shopify store. I have seen multiple ways to so a signature and handle it so yet I am unable to get it working so the ShopifyAPI will work. The action is below, I noticed that:shopify_session filter only works for admin, not customers as well.
def submit_product
query_parameters = Rack::Utils.parse_query(request.query_string)
# Remove and save the "signature" entry
signature = query_parameters.delete("signature")
sorted_params = query_parameters.collect{ |k, v| "#{k}=#{Array(v).join(',')}" }.sort.join
calculated_signature = OpenSSL::HMAC.hexdigest(OpenSSL::Digest::Digest.new('sha256'), ENV['SHOPIFY_SECRET'], sorted_params)
raise 'Invalid signature' if signature != calculated_signature
#store = Store.where(shopify_url: query_parameters['shop']).first
if #store.present?
#product = #store.products.new
#product.images.build
#product_types = ShopifyAPI::CustomCollection.find(#store.customizable_collection_id).products
end
end

Before you can connect to the ShopifyAPI you should first establish an API session. Otherwise the ShopifyAPI::CustomCollection.find method can't connect to Shopify. Steps 3 and 4 of the shopify_api README include the following example:
session = ShopifyAPI::Session.new("SHOP_NAME.myshopify.com", token)
ShopifyAPI::Base.activate_session(session)
product_types = ShopifyAPI::CustomCollection.find(id)
token is the permanent access token which you can request during the OAuth Authentication phase (the installation of the App into a shop).

#gmail_response = Net::HTTP.get_response(uri)
can some one help me with this
Answer
You are missing the token in your code, that's why your requests are HTTP 401 Unauthorized, I strongly recommend you to use the Official documentation Quickstart In your case, you should use the list_user_messages method.
First of all list all the messages using the q parameter as in:sent which means read all the sent messages from my Gmail and then count your array of messages. Here's an example:
# ...
# Previous quickstart code
user_id = "email#example.com"
result = service.list_user_messages(user_id=user_id, q="in:sent")
puts "count : #{result.messages.length()}\n\n"

Ruby Google API Client
Method: users.messages.list

How to implement google smart lock one tap sign in

I want to implement Google's One tap sign-up and automatic sign-in in my website with the help of documentation https://developers.google.com/identity/one-tap/web/ but I am getting confused on how to implement in python.
def smartlock(request):
try:
CLIENT_ID='*******'
csrf_token_cookie = self.request.cookies.get('g_csrf_token')
if not csrf_token_cookie:
webapp2.abort(400, 'No CSRF token in Cookie.')
csrf_token_body = self.request.get('g_csrf_token')
if not csrf_token_body:
webapp2.abort(400, 'No CSRF token in post body.')
if csrf_token_cookie != csrf_token_body:
webapp2.abort(400, 'Failed to verify double submit cookie.')
# Specify the CLIENT_ID of the app that accesses the backend:
idinfo = id_token.verify_oauth2_token(csrf_token_cookie, requests.Request(), CLIENT_ID)
# Or, if multiple clients access the backend server:
# idinfo = id_token.verify_oauth2_token(token, requests.Request())
# if idinfo['aud'] not in [CLIENT_ID_1, CLIENT_ID_2, CLIENT_ID_3]:
# raise ValueError('Could not verify audience.')
if idinfo['iss'] not in ['accounts.google.com', 'https://accounts.google.com']:
raise ValueError('Wrong issuer.')
# If auth request is from a G Suite domain:
# if idinfo['hd'] != GSUITE_DOMAIN_NAME:
# raise ValueError('Wrong hosted domain.')
# ID token is valid. Get the user's Google Account ID from the decoded token.
userid = idinfo['sub']
except ValueError:
# Invalid token
pass
'''
As mentioned in the 'Key Point' section of this page: The ID token is returned in the credential field, instead of the g_csrf_token field.
So, you need to get the idinfo with the code as below:
credential = self.request.get('credential')
idinfo = id_token.verify_oauth2_token(credential, requests.Request(), CLIENT_ID)
The g_csrf_token parameter is for different purpose. It makes sure the request was submitted from a page in your own domain, so as to prevent the cross-site-request-forge attacks.

How do I migrate users from OpenID to Google OAuth2/OpenID Connect using Python Social Auth?

Google is deprecating the OpenID endpoint I was using (v1.0 I think, via the django_openid_auth module) and I need to update my app and migrate my users' accounts to use Google OAuth2.
I've changed the app to use python-social-auth and have it authenticating with social.backends.google.GoogleOAuth2 successfully.
I've written a pipeline function to find associated OpenID urls from the old table and this is working for the other backends I care about but Google:
def associate_legacy_user(backend, response, uid=None, user=None,
*args, **kwargs):
if uid and not user:
# Try to associate accounts registered in the old openid table
identity_url = None
if backend.name == 'google-oauth2':
# TODO: this isn't working
identity_url = response.get('open_id')
else:
# for all other backends, see if there is a claimed_id url
# matching the identity_url use identity_url instead of uid
# as uid may be the user's email or username
try:
identity_url = response.identity_url
except AttributeError:
identity_url = uid
if identity_url:
# raw sql as this is no longer an installed app
user_ids = sql_query.dbquery('SELECT user_id '
'FROM django_openid_auth_useropenid '
'WHERE claimed_id = %s',
(identity_url,))
if len(user_ids) == 1:
return {'user': User.objects.get(id=user_ids[0]['user_id'])}
As best I can tell from reading Google's migration guide, I need to add an openid.realm to the request, which I've done as follows in settings.py:
SOCIAL_AUTH_GOOGLE_OAUTH2_AUTH_EXTRA_ARGUMENTS \
= {'openid.realm': 'http://example.com/'}
But this doesn't seem to be returning the open_id value in the response passed into my pipeline function.
I seem to be stuck on Step 3:
I tried sub-classing the backend to change the RESPONSE_TYPE to add id_token but that returned an empty response:
import social.backends.google
class CustomGoogleOAuth2(social.backends.google.GoogleOAuth2):
RESPONSE_TYPE = 'code id_token'
I tried building an additional request to https://www.googleapis.com/oauth2/v3/token similar to this example, but I don't really know how to go about putting that together and debugging it.
Some more details:
My old claimed_ids for Google OpenID users look like: https://www.google.com/accounts/o8/id?id=AItOawmAW18QuHDdn6PZzaiI5BWUb84mZzNB9eo
I'm happy to use social.backends.google.GoogleOpenIdConnect or a similar alternative backend if that's an easier solution. And while it seems to be closer to what the Google docs are talking about, I wasn't able to get it to work when I tried:
I get a 400 Error: invalid_request Parameter not allowed for this message type: nonce
I can get past the nonce error using social.backends.google.GoogleOpenIdConnect by adding id_token to the RESPONSE_TYPE but then I get an AuthMissingParameter error in my /complete/google-openidconnect/ endpoint as the request's GET and POST are empty. (Tried 'code id_token', 'token id_token', 'id_token', ...)
I don't want to use social.backends.google.GooglePlusAuth as that doesn't integrate as nicely with my current login form.
Worst case, I should be able to use social.pipeline.social_auth.associate_by_email, but I only have email addresses for maybe 80% of the users so that leaves quite a few who will have a new account and need support to associate it manually.
Try as I might, I can't find any examples of people doing a similar migration with python-social-auth, but it must be happening to lots of people.
Any ideas?
Solution works for python social auth 0.1.26
In new versions (0.2.*) of python social auth, there is GoogleOpenIdConnect, but it does not work fine (at least I did not succeed). And my project has some legacy, so I can't use new version of social.
I wrote custom GoogleOpenIdConnect backend:
import datetime
from calendar import timegm
from jwt import InvalidTokenError, decode as jwt_decode
from social.backends.google import GoogleOAuth2
from social.exceptions import AuthTokenError
class GoogleOpenIdConnect(GoogleOAuth2):
name = 'google-openidconnect'
ACCESS_TOKEN_URL = 'https://www.googleapis.com/oauth2/v3/token'
DEFAULT_SCOPE = ['openid']
EXTRA_DATA = ['id_token', 'refresh_token', ('sub', 'id')]
ID_TOKEN_ISSUER = "accounts.google.com"
def user_data(self, access_token, *args, **kwargs):
return self.get_json(
'https://www.googleapis.com/plus/v1/people/me/openIdConnect',
params={'access_token': access_token, 'alt': 'json'}
)
def get_user_id(self, details, response):
return response['sub']
def request_access_token(self, *args, **kwargs):
"""
Retrieve the access token. Also, validate the id_token and
store it (temporarily).
"""
response = self.get_json(*args, **kwargs)
response['id_token_parsed'] = self.validate_and_return_id_token(response['id_token'])
return response
def validate_and_return_id_token(self, id_token):
"""
Validates the id_token according to the steps at
http://openid.net/specs/openid-connect-core-1_0.html#IDTokenValidation.
"""
try:
id_token = jwt_decode(id_token, verify=False)
except InvalidTokenError as err:
raise AuthTokenError(self, err)
# Verify the token was issued in the last 10 minutes
utc_timestamp = timegm(datetime.datetime.utcnow().utctimetuple())
if id_token['iat'] < (utc_timestamp - 600):
raise AuthTokenError(self, 'Incorrect id_token: iat')
return id_token
Notes:
get_user_id – An identifier for the user, unique among all Google accounts and never reused.
request_access_token – there is I add id_token_parsed to response, and it will be used in pipeline.
validate_and_return_id_token – validate of jwt is disabled, because in google developers console I have registered Client ID as web application so, I have no certificates for validate this data.
Then I created pipelines:
def social_user_google_backwards(strategy, uid, *args, **kwargs):
"""
Provide find user that was connect with google openID, but is logging with google oauth2
"""
result = social_user(strategy, uid, *args, **kwargs)
provider = strategy.backend.name
user = result.get('user')
if provider != 'google-openidconnect' or user is not None:
return result
openid_id = kwargs.get('response', {}).get('id_token_parsed', {}).get('openid_id')
if openid_id is None:
return result
social = _get_google_openid(strategy, openid_id)
if social is not None:
result.update({
'user': social.user,
'is_new': social.user is None,
'google_openid_social': social
})
return result
def _get_google_openid(strategy, openid_id):
social = strategy.storage.user.get_social_auth('openid', openid_id)
if social:
return social
return None
def associate_user(strategy, uid, user=None, social=None, *args, **kwargs):
result = social_associate_user(strategy, uid, user, social, *args, **kwargs)
google_openid_social = kwargs.pop('google_openid_social', None)
if google_openid_social is not None:
google_openid_social.delete()
return result
And changed my SOCIAL_AUTH_PIPELINE and AUTHENTICATION_BACKENDS settings:
AUTHENTICATION_BACKENDS = (
...
#'social.backends.open_id.OpenIdAuth' remove it
'social_extension.backends.google.GoogleOpenIdConnect', # add it
...
)
and
SOCIAL_AUTH_PIPELINE = (
'social.pipeline.social_auth.social_details',
'social.pipeline.social_auth.social_uid',
'social.pipeline.social_auth.auth_allowed',
# 'social.pipeline.social_auth.social_user', remove it
'social_extension.pipeline.social_user_google_backwards', # add it
'social.pipeline.user.get_username',
...
# 'social.pipeline.social_auth.associate_user', remove it
'social_extension.pipeline.associate_user', # add it
'social.pipeline.social_auth.load_extra_data',
...
)

Twitter 3-legged authorization in Ruby

I am trying my hand ruby on rails. Mostly I have written code in Sinatra. Anyway this question may not have to do anything with framework. And this question may sound a very novice question. I am playing with Twitter 1.1 APIs and OAuth first time.
I have created an app XYZ and registered it with Twitter. I got XYZ's consumer key i.e., CONSUMER_KEY and consumer secret i.e. CONSUMER_SECRET. I also got XYZ's own access token i.e ACCESS_TOKEN and access secret i.e. ACCESS_SECRET
XYZ application type: Read, Write and Access direct messages
XYZ callback URL: http://www.mysite.com/cback
And I have checked: Allow this application to be used to Sign in with Twitter
What I am trying to do is very simple:
1) Users come to my website and click a link Link your twitter account (not signin with twitter)
2) That opens twitter popup where user grants permission to XYZ to perform actions on his/her behalf
3) Once user permits and popup gets closed, XYZ app gets user's access token and secret and save in the database.
4) Then XYZ uses that user's token and secret to perform actions in future.
I may be moron that such work flow has been implemented on several thousands sites and Twitter API documentations explain this 3-legged authentication, still I am unable to figure it out.
I have read https://dev.twitter.com/docs/auth/3-legged-authorization and https://dev.twitter.com/docs/auth/implementing-sign-twitter Unfortunately no ruby code found on internet that explains with step by step example.
What link should be used to open twitter authentication page when user clicks Link your twitter account.
Can anyone here, write some pseudo code with my pseduo credential above to achieve my goal from beging till end of this work flow? Thanks.
UPDATE:
I started with requesting request token as
require 'oauth'
consumer = OAuth::Consumer.new(CONSUMER_KEY, CONSUMER_SECRET,
{ site: "https://twitter.com"})
request_token = consumer.get_request_token oauth_callback: 'http://www.mysite.com/tauth'
redirect_to request_token.authorize_url
I'm not familiar with ROR but here is the workflow of the OAuth 'dance' that you need to follow when the user clicks your button:
Obtain an unauthorized request token from Twitter by sending a
request to
POST https://api.twitter.com/oauth/request_token
signing the request using your consumer secret. This will be done in the background and
will be transparent to the user.
You will receive am oauth_token and oauth_token_secret back from
twitter.
Redirect the user to
https://api.twitter.com/oauth/authorize?oauth_token=[token_received_from_twitter]
using the oauth token value you received from Twitter in step 2.
When the user authorizes your app they will be redirected to your
callback url with oauth_token and oauth_verifier appended to the
url. i.e.
http://www.mysite.com/cback?oauth_token=NPcudxy0yU5T3tBzho7iCotZ3cnetKwcTIRlX0iwRl0&oauth_verifer=uw7NjWHT6OJ1MpJOXsHfNxoAhPKpgI8BlYDhxEjIBY
Convert the request token into an access token by sending a signed
request along with the oauth_verifier to
POST
https://api.twitter.com/oauth/access_token
signing your request
with your consumer secret and the token secret received in step 2.
If everything goes ok, you will receive a new oauth_token and
oauth_token_secret from Twitter. This is your access token for the
user.
Using the access token and secret received in step 6 you can make
Twitter api calls on behalf the the user by sending signed requests
to the appropriate api endpoints.
Hope you solved your problem by this time, but I built this sample Sign in with Twitter ruby web app that provide all explanation you need to do this integration. Below there's a class that implements all necessary methods with comments:

Trouble authenticating with Google Content API for Shopping

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.
