Authentication token_type=null

[David_Kim]

I actually got the oauth token and should have tried getting user info with it. But was doing the wrong thing… Sorry;;

Currently I’m using Authentication. I’m getting the access_token however token_type and scope keep comes back as null. Am I keeping something out?

I’m trying to get the user’s login address information. It success in login but the scope in oauthToken returns null. How can I fix this or do I have to do more steps?

Here’s my code in Java.

import com.github.scribejava.core.builder.api.DefaultApi20;

public class TwitchLoginApi extends DefaultApi20{

protected TwitchLoginApi(){
}

private static class InstanceHolder{
	private static final TwitchLoginApi INSTANCE = new TwitchLoginApi();
}


public static TwitchLoginApi instance(){
	return InstanceHolder.INSTANCE;
}


@Override
public String getAccessTokenEndpoint() {
	// TODO Auto-generated method stub
	return "https://api.twitch.tv/kraken/oauth2/token?grant_type=authorization_code";
}


@Override
protected String getAuthorizationBaseUrl() {
	// TODO Auto-generated method stub
	return "https://api.twitch.tv/kraken/oauth2/authorize";
}

}

Service class

package service;

import java.io.IOException;
import java.util.UUID;

import javax.servlet.http.HttpSession;

import org.apache.commons.lang.StringUtils;
import org.springframework.stereotype.Service;

import com.github.scribejava.core.builder.ServiceBuilder;

public class TwitchLoginService {

private final static String CLIENT_ID = "ghty8lutmj1064oembb9g8195fr9eg";
private final static String CLIENT_SECRET = "my secret";
private final static String REDIRECT_URI = "http://localhost:8080/InsightGame/twitchCallback.do";
private final static String SCOPE = "user_read";

private String generateRandomString() {
	return UUID.randomUUID().toString();
}

private void setSession(HttpSession session,String state){
	session.setAttribute("state", state);
}

private String getSession(HttpSession session){
	return (String) session.getAttribute("state");
}

public String getAuthorizationUrl(HttpSession session) {
	
	String state = generateRandomString();
	setSession(session,state);
	
	OAuth20Service oauthService = new ServiceBuilder()
			.apiKey(CLIENT_ID)
			.apiSecret(CLIENT_SECRET)
			.callback(REDIRECT_URI)
			.scope("user_read")
			.state(state)
			.build(TwitchLoginApi.instance());
	//System.out.println(oauthService.getAuthorizationUrl());
	return oauthService.getAuthorizationUrl();
}

public OAuth2AccessToken getAccessToken(HttpSession session, String code, String state) throws IOException{
	
	String sessionState = getSession(session);
	
	if(StringUtils.equals(sessionState, state)){
		OAuth20Service oauthService = new ServiceBuilder()
				.apiKey(CLIENT_ID)
				.apiSecret(CLIENT_SECRET)
				.callback(REDIRECT_URI)
				.scope("user_read")
				.state(state)
				.build(TwitchLoginApi.instance());
				
		OAuth2AccessToken accessToken = oauthService.getAccessToken(code);
		System.out.println(accessToken);
		return accessToken;
	}
	return null;
	
}

}

The result I get back is
OAuth2AccessToken{access_token=06z2rpaznutjxx0zauquxgm6wbt5hf, token_type=null, expires_in=14015, refresh_token=m3srhojf69v41nv1dtsrvtqy0tqtg1nn7ljta9lgu6ibh7emy9, scope=null}
