Apache Oltu Github integration example with Spring MVC - oauth

Question

I'm developing an "Apache Oltu Spring MVC Github" integration example. In this example I will be sending "App ID" and "Secret" to get the "access_token" in order to access the protected resources like "Gist", "user" etc.
So first step is to create / register the "App" using https://github.com/settings/applications/new.
Once you create a App make sure to Note: AppID and Secret, we need these values to be used in Spring code.
To develop this functionality / code - I search a lot and I did not find any ready made code. So I decided to furnish / explain my code below. So one can find these links useful.
I've taken a reference of following URL's to developed whole code:-
https://developer.github.com/v3/oauth/
https://cwiki.apache.org/confluence/display/OLTU/OAuth+2.0+Client+Quickstart

Answer 1

Attached is the screen shot to register the "App" on Github. "MyApp" is the App that I created.
Use the same code from http://www.jasha.eu/blogposts/2013/09/retrieve-facebook-profile-data-java-apache-oltu.html, just make sure to change the
AUTHORIZATION_URL = "https://github.com/login/oauth/authorize";
ACCESS_TOKEN_URL = "https://github.com/login/oauth/access_token"
To get Protected Resource like User Profile use: https://api.github.com/user
The output I get when run the code:

The user4798111 has mentioned is correct and just adding some more details. Pre-requisite, you need to register App on Github. Once you registered the App, you will get the CLIENT_SECRET,CLIENT_ID to be used to get the Protected resources from the github.
If you're using the OAuthClientRequest API to to make an initial call, you need to have the following details
private static final String AUTHORIZATION_URL = "https://github.com/login/oauth/authorize";
private static final String CLIENT_ID = "8515a1e4XXXXXXX";
private static final String CLIENT_SECRET = "ae3487601d891d257f7193XXXXXXXXX";
private static final String REDIRECT_URL = "http://localhost:8080/apache-oltu/github/redirect";
private static final String ACCESS_TOKEN_URL = "https://github.com/login/oauth/access_token";
#RequestMapping(value = "/auth", method = RequestMethod.GET)
public String authenticate() throws OAuthSystemException {
OAuthClientRequest request = OAuthClientRequest
.authorizationLocation(AUTHORIZATION_URL)
.setClientId(CLIENT_ID)
.setRedirectURI(REDIRECT_URL)
.setResponseType("code")
.setScope("user,gist,user:email,user:follow,public_repo,repo,repo_deployment,repo:status,repo:invite")
.buildQueryMessage();
System.out.println("REDIRECT TO: "+request.getLocationUri());
return "redirect:" + request.getLocationUri();
}
The same something simllar you would need to use like below
request= new OAuthBearerClientRequest("https://api.github.com/user").
setAccessToken(oAuthResponse.getAccessToken()).
buildQueryMessage();
The information about the scopes and other details can be found here:
https://developer.github.com/apps/building-integrations/setting-up-and-registering-oauth-apps/about-authorization-options-for-oauth-apps/
https://developer.github.com/apps/building-integrations/setting-up-and-registering-oauth-apps/about-scopes-for-oauth-apps/
The result which could see is below for reference:
