Google authentication using service account - google-drive-api

GoogleCredential credential = new GoogleCredential.Builder()
.setTransport(TRANSPORT)
.setJsonFactory(JSON_FACTORY)
.setServiceAccountId("SOMETHING#developer.gserviceaccount.com")
.setServiceAccountScopes(BigqueryScopes.BIGQUERY)
.setServiceAccountPrivateKeyFromP12File(new File("key.p12"))
.build();
i tried above code to authenticate using service account. But
GoogleCredential is deprecated. So i am trying to use Credential.
But i am not able to understand what is mean by AccessMethod.
Can you please help me to refractor this code using Credential instead of GoogleCredential?

Like you said, and as explained in its JavaDoc reference, this class has been deprecated:
Deprecated.
Please use google-auth-library for handling Application Default Credentials and other non-OAuth2 based authentication.
Note that it already points you to another library: google-auth-library. In that repository there is an exaple of an impresionation by using it.

Mediawiki AuthManager and SessionManager SSO

I am currently using 1.24.x and using LoginForm class and FauxRequest to login the remote (and create it locally if it doesn't exist) but this feature is being removed in 1.27.x so I am forced to write with a new standard using AuthManager and SessionMamager. I also will be upgrading to 1.31 as soon as LTS version of it comes out.
While reading, AuthManager and SessionManager, I just can't understand how can I authenticate external users. I also looked at the extension pluggableSSO which uses PluggableAuth but can't understand it as well.
Can someone please point me to a straightforward example of how can I authenticate a user if I have a user id and user name? and if that user doesn't exist, how can I create one and authenticate them locally?
Thanks
If someone like me who is very new to MediaWiki, there is a solution for SSO called PluggableAuth and Auth_Remoteuser.
I picked PluggableAuth which is implemented based on AuthManager and it is very easy to integrate.
All we need is to define a global variable $PluggableAuth_Class and implement the following methods in it:
public function authenticate( &$id, &$username, &$realname, &$email, &$errorMessage )
public function saveExtraAttributes( $id )
public function deauthenticate( User &$user )
More information can be found on:

How do you add your own Oauth2 Passport strategy to a FeathersJS app?

Apologies in advance for what might be an obvious question/answer, but I keep scouring the docs and cannot find it.
I know FeathersJS has drop-in strategies for Facebook/Twitter/Github -- I see those in the docs. And I know you can do all sorts of customization authorization strategies. All I am looking to do is authenticate users through a Oauth2 provider that doesnt already have a pre-packaged strategy. I cannot find a working example that does this.
More frustratingly, when I try to follow examples/docs, I get errors coming from the feathersjs npm modules, like:
<...>/node_modules/#feathersjs/authentication-oauth2/lib/index.js:96
app.passport.use(name, new Strategy(oauth2Settings, verifier.verify.bind(verifier)));
^
TypeError: Strategy is not a constructor
Does anyone have a working example?
That error means that you didn't pass a Passport oAuth2 strategy. You can set up the general Passport oAuth2 adapter very similar to the example in the documentation:
const oauth2 = require('#feathersjs/authentication-oauth2');
const OAuth2Strategy = require('passport-oauth2').Strategy;
app.configure(oauth2({
name: 'custom',
Strategy: OAuth2Strategy,
authorizationURL: 'https://www.example.com/oauth2/authorize',
tokenURL: 'https://www.example.com/oauth2/token',
clientID: EXAMPLE_CLIENT_ID,
clientSecret: EXAMPLE_CLIENT_SECRET,
callbackURL: "http://localhost:3000/auth/example/callback"
}));

Using Google Cloud Dataflow how do I run with proper credentials on a GCE Compute instance?

I'm new to Google Cloud Dataflow, as is probably obvious from my questions below.
I've got a dataflow application written and can get it to run without issue using my personal credentials both locally and on a GCE instance. However, I can't seem to crack the proper steps to get it to run using the compute engine instance's service credentials or service credentials I've created using the API & AUTH section of the console. I always get a 401 not authorized error when I run.
Here's what I've tried...
1) Created virtual machine granting access rights to storage, datastore, sql and compute engine. My understanding is that this supposedly created a CI specific services account that is the server's default credentials. These should be used the same way a user's authentication is used when an app is run on this instance. Here's where I get a 401. My question is... Where can I see this service account that was supposedly created? Or do I just rely that it exists somewhere?
2) Created service credentials in API & Auth portion of developer's console. Then used cloud auth activate-service-account and activated that account by pointing the command at the credentials json file I downloaded. Kind of like the OAUTH round trip when you use gcloud auth login. Here I also get the 401.
3) This last thing was using the service credentials from step 2 separate from the GCE instance and then create an object that implements the CredentialFactory interface and pass it off to the PipelineOptions. However, when it runs the app crashes now with an error saying that it is looking for a method, fromOptions, that isn't in the CredentialFactory interface. How the options were configured, what the credentials factory looked like and the stack trace from this follows.
I would be happy to utilize any of the above 3 methods to make use of service credentials, if I could get any of them to work. Any insight you can provide on what I'm doing wrong, steps I'm leaving out, other unexplored options would be greatly appreciated. The documentation is a little dis-jointed. If there is a clear step by step guide a link to that would be sufficient. What I've found so far on my own has been of little assistance.
If I can provide any additional information please let me know.
Here's some code that may be helpful and the stack trace I get when the code runs using the credential factory.
Options setup code looks like this:
GcrDataflowPipelineOptions options = PipelineOptionsFactory.fromArgs(args)
.withValidation()
.as(GcrDataflowPipelineOptions.class);
options.setKind("Counties");
options.setCredentialFactoryClass(GoogleCredentialProvider.class);
GoogleCredentialProvider.java
Notice the json file I downloaded as part of creating the services account (renamed) is what's loaded as a resource from my apps class path.
public class GoogleCredentialProvider implements CredentialFactory {
#Override
public Credential getCredential() throws IOException, GeneralSecurityException {
final String env = System.getProperty("gcr_dataflow_env", "local");
Properties props = new Properties();
ClassLoader loader = this.getClass().getClassLoader();
props.load(loader.getResourceAsStream(env + "-gcr-dataflow.properties"));
final String credFileName = props.getProperty("gcloud.dataflow.service.account.file");
InputStream credStream = loader.getResourceAsStream(credFileName);
GoogleCredential credential = GoogleCredential.fromStream(credStream);
return credential;
}
}

You likely do not have the proper credentials. When you execute a Dataflow job from GCE, The service account attached to the instance will be used for validation by DataFlow.
Did you do this when creating your machines?
create a service account for the instance on GCE?

Set the required scopes for using Dataflow such as storage, compute,
and bigquery? https://www.googleapis.com/auth/cloud-platform

box-api unable to get auth_token

I am trying to develop an integration with box. I am using "box-api", "~> 0.2.2" gem. I have an api key.
box_object = Box::Api.new("j7p3zz29xgva8t52lgoptyxuavtji66y")
ticket = box_object.get_ticket
auth_key= box_object.get_auth_token(ticket[:ticket])
i am getting this exception
Box::Api::NotAuthorized: not_logged_in
Can anyone suggest what is going wrong?
the ticket is used to construct a URL to which your app must redirect the user. This is the first leg of the v1 authentication process. This documentation provides a guide.
Apart from checking the above answers, also ensure that box admin has approved an app before it can be used.

Google Drive/OAuth - Can't figure out how to get re-usable GoogleCredentials

I've successfully installed and run the Google Drive Quick Start application called DriveCommandLine. I've also adapted it a little to GET file info for one of the files in my Drive account.
What I would like to do now is save the credentials somehow and re-use them without the user having to visit a web page each time to get an authorization code. I have checked out this page with instructions to Retrieve and Use OAuth 2.0 credentials. In order to use the example class (MyClass), I have modified the line in DriveCommandLine where the Credential object is instantiated:
Credential credential = MyClass.getCredentials(code, "");
This results in the following exception being thrown:
java.lang.NullPointerException
at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:187)
at com.google.api.client.json.jackson.JacksonFactory.createJsonParser(JacksonFactory.java:84)

at googledrive.DriveCommandLine.main(DriveCommandLine.java:115)
I've been looking at these APIs (Google Drive and OAuth) for 2 days now and have made very little progress. I'd really appreciate some help with the above error and the problem of getting persistent credentials in general.
This whole structure seems unnecessarily complicated to me. Anybody care to explain why I can't just create a simple Credential object by passing in my Google username and password?
Thanks,
Brian O Carroll, Dublin, Ireland
* Update *
Ok, I've just gotten around the above error and now I have a new one.
The way I got around the first problem was by modifying MyClass.getFlow(). Instead of creating a GoogleClientServices object from a json file, I have used a different version of GoogleAuthorizationCodeFlow.Builder that allows you to enter the client ID and client secret directly as Strings:
flow = new GoogleAuthorizationCodeFlow.Builder(httpTransport, jsonFactory, "<MY CLIENT ID>", "<MY CLIENT SECRET>", SCOPES).setAccessType("offline").setApprovalPrompt("force").build();
The problem I have now is that I get the following error when I try to use flow (GoogleAuthorizationCodeFlow object) to exchange the authorization code for the Credentials object:
An error occurred: com.google.api.client.auth.oauth2.TokenResponseException: 400 Bad Request
{
"error" : "invalid_scope"
}

at googledrive.MyClass.getCredentials(MyClass.java:262)
at googledrive.DriveCommandLine.<init>(DriveCommandLine.java:56)
at googledrive.DriveCommandLine.main(DriveCommandLine.java:115)
Is there some other scope I should be using for this? I am currently using the array of scopes provided with MyClass:
private static final List<String> SCOPES = Arrays.asList(
"https://www.googleapis.com/auth/drive.file",
"https://www.googleapis.com/auth/userinfo.email",
"https://www.googleapis.com/auth/userinfo.profile");
Thanks!
I feel your pain. I'm two months in and still getting surprised.
Some of my learnings...
When you request user permissions, specify "offline=true". This will ("sometimes" sic) return a refreshtoken, which is as good as a password with restricted permissions. You can store this and reuse it at any time (until the user revokes it) to fetch an access token.
My feeling is that the Google SDKs are more of a hinderence than a help. One by one, I've stopped using them and now call the REST API directly.
On your last point, you can (just) use the Google clientlogin protocol to access the previous generation of APIs. However this is totally deprecated and will shortly be turned off. OAuth is designed to give fine grained control of authorisation which is intrinsically complex. So although I agree it's complicated, I don't think it's unnecessarily so. We live in a complicated world :-)
Your and mine experiences show that the development community is still in need of a consolidated document and recipes to get this stuff into our rear-view mirrors so we can focus on the task at hand.
Oath2Scopes is imported as follows:
import com.google.api.services.oauth2.Oauth2Scopes;
You need to have the jar file 'google-api-services-oauth2-v2-rev15-1.8.0-beta.jar' in your class path to access that package. It can be downloaded here.
No, I don't know how to get Credentials without having to visit the authorization URL at least once and copy the code. I've modified MyClass to store and retrieve credentials from a database (in my case, it's a simple table that contains userid, accesstoken and refreshtoken). This way I only have to get the authorization code once and once I get the access/refresh tokens, I can reuse them to make a GoogleCredential object. Here's how Imake the GoogleCredential object:
GoogleCredential credential = new GoogleCredential.Builder().setJsonFactory(jsonFactory)
.setTransport(httpTransport).setClientSecrets(clientid, clientsecret).build();
credential.setAccessToken(accessToken);
credential.setRefreshToken(refreshToken);
Just enter your clientid, clientsecret, accessToken and refreshToken above.
I don't really have a whole lot of time to separate and tidy up my entire code to post it up here but if you're still having problems, let me know and I'll see what I can do. Although, you are effectively asking a blind man for directions. My understanding of this whole system is very sketchy!
Cheers,
Brian
Ok, I've finally solved the second problem above and I'm finally getting a working GoogleCredential object with an access token and a refresh token.
I kept trying to solve the scopes problem by modifying the list of scopes in MyClass (the one that manages credentials). In the end I needed to adjust the scopes in my modified version of DriveCommandLine (the one that's originally used to get an authorization code). I added 2 scopes from Oauth2Scopes:
GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
httpTransport, jsonFactory, CLIENT_ID, CLIENT_SECRET,
Arrays.asList(DriveScopes.DRIVE, Oauth2Scopes.USERINFO_EMAIL, Oauth2Scopes.USERINFO_PROFILE))
.setAccessType("offline").setApprovalPrompt("force").build();
Adding the scopes for user information allowed me to get the userid later in MyClass. I can now use the userid to store the credentials in a database for re-use (without having to get the user to go to a URL each time). I also set the access type to "offline" as suggested by pinoyyid.
