Testing Doorkeeper oAuth2 for Zapier App - ruby-on-rails

Question
How would we test a Doorkeeper oauth2 implementation for a Zapier cli app?
Background
I have a Rails 3 app. I am trying to create a Zapier client for the application and I decided to use OAuth. Thus I configured doorkeeper to generate a JWT. All looks good, I am able to authorize and get token using the redirects.
I am not sure how to test the app purely through the console. Wouldn't it require some way to authorize using username/password?
I got an app generated from the template with some minor differences.
it('can fetch an access token', (done) => {
const bundle = {
inputData: {
// In production, Zapier passes along whatever code your API set in the query params when it redirects
// the user's browser to the `redirect_uri`
code: 'one_time_code',
subdomain: 'ducks'
},
environment: {
CLIENT_ID: process.env.CLIENT_ID,
CLIENT_SECRET: process.env.CLIENT_SECRET
}
};
appTester(App.authentication.oauth2Config.getAccessToken, bundle)
.then((result) => {
result.access_token.should.eql('a_token');
result.refresh_token.should.eql('a_refresh_token');
done();
})
.catch(done);
});
results in something like this:
1) oauth2 app can fetch an access token:
Got 401 calling POST https://ducks.<domain>.com/oauth/token, triggering auth refresh.
What happened:
Starting POST request to https://ducks.<domain>.com/oauth/token
Received 401 code from https://ducks.<domain>.com/oauth/token after 1425ms
Received content "{"error":"invalid_request","error_description":"The request is missing a required parameter, include"
Got 401 calling POST https://ducks.<domain>.com/oauth/token, triggering auth refresh.
Which should be because the user is not logged in the request made in the test console...
How can I make the user login? Or should the tests be changed?

Discord Oauth2 receiving 'invalid client' error

I had Discord Oauth2 implemented so that my users could log into my website by authenticating through Discord. For months, everything worked great and now all of the sudden it stopped working.
Per Discord's oauth2 instructions,https://discordapp.com/developers/docs/topics/oauth2#shared-resources, I am able to successfully acquire the access code that is meant to be traded for the access token. However, when I try to receive the access token I receive an 'invalid_client' error.
First, I am hitting this endpoint:
https://discordapp.com/api/oauth2/authorize?client_id=${process.env.CLIENT_ID}&redirect_uri=http%3A%2F%2Flocalhost%3A5000%2Flogin%2Fdiscord%2Fcallback&response_type=code&scope=identify%20email%20gdm.join
which successfully returns the following:
http://localhost:5000/login/discord/callback?code={some_access_code}
The access code is then sent back to discord to obtain the access token. Here is the code that is failing:
export function getDiscordAccessToken(accessCode, call) {
const redirect = call === 'login' ? process.env.DISCORD_LOGIN_REDIRECT : process.env.DISCORD_CONNECT_REDIRECT
return new Promise((resolve, reject) => {
axios
.post(
`https://discordapp.com/api/oauth2/token?client_id=${process.env.DISCORD_CLIENTID}&client_secret=${process.env.DISCORD_SECRET}&grant_type=authorization_code&code=${accessCode}&redirect_uri=${redirect}&scope=identify%20email%20gdm.join`
)
.then(res => {
resolve(res.data)
})
.catch(err => {
// log error to db
console.log("Here is your error: ", err.response)
reject(err.response)
})
})
}
This code was working for months with no problems. Then, all of the sudden it stopped working. I even checked the Discord change logs which can be found here, https://discordapp.com/developers/docs/change-log, but I found no reference to authentication changes.
Any help you can provide is greatly appreciated!
The query parameters should be in the BODY of the POST request, not the URL for the oauth/token url.
Discord recently pushed a update to the oAuth2 which makes it confine more with the standard. This means they no longer support parameters in the URL for POST, but instead require them to be in the body and form encoded (basically the same, but in the body and without the leading ?).
So you basically need (not tested):
axios.post(
`https://discordapp.com/api/oauth2/token`,
`client_id=${process.env.DISCORD_CLIENTID}&client_secret=${process.env.DISCORD_SECRET}&grant_type=client_credentials&code=${accessCode}&redirect_uri=${redirect}&scope=identify%20email%20gdm.join`
)
I know the question has already been answered, but in my case I copied a wrong secret key. Just make sure that you copy the right one.
Secret Key is located under OAuth2 Tab and not under General Information tab on discord developer's dashboard.

Microsoft Graph API access token validation failure

I use this URL to get id_token:
https://login.microsoftonline.com/common/oauth2/authorize?
response_type=id_token%20code&
client_id=MY_CLIENT_GUID_ID_IN_HERE&
redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fauth%2Fopenid%2Freturn&nonce=alfaYYCTxBK8oypM&
state=6DnAi0%2FICAWaH14e
and this return result like this
http://localhost:3000/auth/openid/return?
code=AAA_code_in_here&
id_token=eyJ0eXAi_xxxx_yyyy_in_here&
state=6DnAi0%2FICAWaH14e&
session_state=xxxx_guid_xxxxx
and then i use the id_token to query Graph (use POST man)
i have see this post InvalidAuthenticationToken and CompactToken issues - Microsoft Graph using PHP Curl but make no sense.
OATH 2.0 requires multiple steps. The first request returns an OAUTH Code. The next step is converting that OATUH code into a Bearer Token. This is the step you are missing here.
I would also recommend using the v2 Endpoint which is a lot easier to work with (particularly with Graph). I wrote a v2 Endpoint Primer that walks through the process and may be helpful as well.
You can't use the token directly, there is one more step to exchange the code you get from the response url into token.
Here is my C# code (using Microsoft.IdentityModel.Clients.ActiveDirectory)
public static AuthenticationResult ExchangeCodeForToken(string InTenantName, string InUserObjId, string InRedirectUri, string InApplicationAzureClientID, string InApplicationAzureClientAppKey)
{
Check.Require(!string.IsNullOrEmpty(InTenantName), "InTenantName must be provided");
Check.Require(!string.IsNullOrEmpty(InUserObjId), "InUserObjId must be provided");
if (CanCompleteSignIn) //redirect from sign-in
{
var clientCredential = new ClientCredential(InApplicationAzureClientID, InApplicationAzureClientAppKey);
var authContext = new AuthenticationContext(Globals.GetLoginAuthority(InTenantName), (TokenCache)new ADALTokenCache(InUserObjId)); //Login Authority is https://login.microsoftonline.com/TenantName
return authContext.AcquireTokenByAuthorizationCode(VerificationCode, new Uri(InRedirectUri), clientCredential, Globals.AZURE_GRAPH_API_RESOURCE_ID); //RESOURCE_ID is "https://graph.microsoft.com/"
}
return null;
}
I had this issue today when I was playing with graph API, the problem in my case was how I was generating the token.
I used postman for generating the token wherein the Auth URL section I was adding the resource = client_id whereas it should be the graph URL. After making that change I was able to make the call via postman.
In order for the above to work, please make sure your application in Azure has delegated permissions to access the Graph API.
To receive the access token and use it for profile requests, you don't need anything from server-side, you can implement the oAuth2 just from the client side.
Use the following URL for login:
https://login.microsoftonline.com/common/oauth2/authorize?client_id=YOUR_CLIENT_ID&resource=https://graph.microsoft.com&response_type=token&redirect_uri=YOUR_REDIRECT_URI&scope=User.ReadBasic.All
After successful login, user will redirected to the page with access_token parameter. Then use the following AJAX call to fetch user info:
var token = login_window.location.href.split('access_token=').pop().split('&')[0];
$.ajax({
url: "https://graph.microsoft.com/v1.0/me",
type: "GET",
beforeSend: function(xhr){xhr.setRequestHeader('Authorization', 'Bearer '+token);},
success: function(data) {
alert('Hi '+data.displayName);
console.log(data);
}
});
Note that you may need to enable oauth2AllowImplicitFlow:true setting from your Azure Active Directory application manifest file.
Set "oauth2AllowImplicitFlow": false to "oauth2AllowImplicitFlow": true.
Lastly, ensure that your app has required permissions for Microsoft Graph which are sign in users and View users' basic profile
An updated answer to get access with new applications:
Register your app in the app registration portal.
Authorization request example:
https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize?client_id=6731de76-14a6-49ae-97bc-6eba6914391e&response_type=code&redirect_uri=http%3A%2F%2Flocalhost%2Fmyapp%2F&response_mode=query&scope=offline_access%20user.read%20mail.read&state=12345
Authorization response will look like this:
https://localhost/myapp/?code=M0ab92efe-b6fd-df08-87dc-2c6500a7f84d&state=12345
Get a token
POST /{tenant}/oauth2/v2.0/token HTTP/1.1
Host: https://login.microsoftonline.com
Content-Type: application/x-www-form-urlencoded
client_id=6731de76-14a6-49ae-97bc-6eba6914391e
&scope=user.read%20mail.read
&code=OAAABAAAAiL9Kn2Z27UubvWFPbm0gLWQJVzCTE9UkP3pSx1aXxUjq3n8b2JRLk4OxVXr...
&redirect_uri=http%3A%2F%2Flocalhost%2Fmyapp%2F
&grant_type=authorization_code
&client_secret=JqQX2PNo9bpM0uEihUPzyrh // NOTE: Only required for web apps
Use the access token to call Microsoft Graph
GET https://graph.microsoft.com/v1.0/me
Authorization: Bearer eyJ0eXAiO ... 0X2tnSQLEANnSPHY0gKcgw
Host: graph.microsoft.com
Source:
https://learn.microsoft.com/en-us/graph/auth-v2-user?context=graph/api/1.0
You can also get an access token without a user, see here:

What is the best way to dynamically specify the redirect url for OAuth strategies in passport.js?

I have setup my facebook auth per passportjs docs:
var passport = require('passport')
, FacebookStrategy = require('passport-facebook').Strategy;
passport.use(new FacebookStrategy({
clientID: FACEBOOK_APP_ID,
clientSecret: FACEBOOK_APP_SECRET,
callbackURL: "http://www.example.com/facebook/callback"
},
function(accessToken, refreshToken, profile, done) { ... });
}
));
app.get('/login/facebook', passport.authenticate('facebook'))
.get('/facebook/callback', passport.authenticate('facebook', {successRedirect: '/', failureRedirect: '/login'}));
All this works fine. However, there are cases (such as token expiration) when I want to automatically redirect the user to the page that the user was on before initiating the login request. So I tried to plumb a query string param through the login request (from client to server to facebook and back). But I cant see a way to specify that in the callbackURL.
Furthermore, when I tried hard-coding some context param to the config callbackURL (eg: "http://www.example.com/facebook/callback?redir=lastUserPage") I get an OAuth parse error. Interestingly enough, Facebook does respond correctly with the access code as well as the redir param, but it fails with OAUTH exception:
FacebookTokenError: Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request
at Strategy.parseErrorResponse (C:\Sources\node_modules\passport-facebook\lib\strategy.js:198:12)

at IncomingMessage.<anonymous> (C:\Sources\node_modules\passport-facebook\node_modules\passport-oauth2\node_modules\oauth\lib\oauth2.js:143:7)
at IncomingMessage.emit (events.js:117:20)
at _stream_readable.js:943:16
at process._tickCallback (node.js:419:13)
Note that I had this working using WIF before. I don't see any security concerns with passing additional query string parameters through the OAuth process..
Any idea how I can get past this?
I'm not sure how to do what you're asking, but for your desired end goal you could:
Save a cookie before authenticating
Authenticate the user
on the resulting callback page, check for the cookie and redirect if present.
Wouldn't this work just as easily?

Cannot get oAuth2 Access Token for Google Analytics API

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.

How to use OAuth access for GMail with libEtPan?

Does anyone have sample code or clear instructions on how to use libEtPan to connect to a GMail account using OAuth? I couldn't find anything.
Details for OAuth in GMail are here: http://code.google.com/apis/gmail/oauth/
libetpan has some documentation in its header files, for IMAP it's in https://github.com/dinhviethoa/libetpan/blob/master/src/low-level/imap/mailimap_oauth2.h
/*
mailimap_oauth2_authenticate()
Authenticates the client using using an oauth2 token.
To gather a deeper understanding of the OAuth2 aunthentication
process refer to: https://developers.google.com/gmail/xoauth2_protocol
For a quick start you may follow this brief set of steps:
1. Set up a profile for your app in the Google
API Console: https://code.google.com/apis/console
2. With your recently obtained client_id and secret
load the following URL (everything goes ina single line):
https://accounts.google.com/o/oauth2/auth?client_id=[YOUR_CLIENT_ID]&
redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&
response_type=code&scope=https%3A%2F%2Fmail.google.com%2F%20email&
&access_type=offline
3. The user most follow instructions to authorize application access
to Gmail.
4. After the user hits the "Accept" button it will be redirected to another
page where the access token will be issued.
5. Now from the app we need and authorization token, to get one we issue a POST request
the following URL: https://accounts.google.com/o/oauth2/token using these parameters:
client_id: This is the client id we got from step 1
client_secret: Client secret as we got it from step 1
code: This is the code we received in step 4
redirect_uri: This is a redirect URI where the access token will be sent, for non
web applications this is usually urn:ietf:wg:oauth:2.0:oob (as we got from step 1)
grant_type: Always use the authorization_code parameter to retrieve an access and refresh tokens
6. After step 5 completes we receive a JSON object similar to:
{
"access_token":"1/fFAGRNJru1FTz70BzhT3Zg",
"refresh_token":"1/fFAGRNJrufoiWEGIWEFJFJF",
"expires_in":3920,
"token_type":"Bearer"
}
The above output gives us the access_token, now we need to also retrieve the user's e-mail,
to do that we need to perform an HTTP GET request to Google's UserInfo API using this URL:
https://www.googleapis.com/oauth2/v1/userinfo?access_token=[YOUR_ACCESS_TOKEN]
this will return the following JSON output:
{
"id": "00000000000002222220000000",
"email": "email#example.com",
"verified_email": true
}
#param session IMAP session
#param auth_user Authentication user (tipically an e-mail address, depends on server)
#param access_token OAuth2 access token
#return the return code is one of MAILIMAP_ERROR_XXX or
MAILIMAP_NO_ERROR codes
*/
LIBETPAN_EXPORT
int mailimap_oauth2_authenticate(mailimap * session, const char * auth_user,
const char * access_token);
LIBETPAN_EXPORT
int mailimap_has_xoauth2(mailimap * session);
I haven't tried it out myself yet, but when I get around to implement it I'll post a link of the implementation.
Update March 2021
I finally got around to implement support for Google OAuth 2.0 in my email client nmail now. The commit can be viewed here but essentially I ended up doing steps 2-6 above in a separate external script, as libetpan does not do the token generation/refresh for us. The token handling is fairly straight-forward - see oauth2nmail.py for example.
