Hi, I think my code is all right but I keep getting the following error when I try to post a message:
[TwitterException: 401:Authentication credentials (https://dev.twitter.com/pages/auth) were missing or incorrect. Ensure that you have set valid consumer key/secret, access token/secret, and the system clock is in sync.
message - Invalid or expired token.
code - 89
]
Here is my code:
package controllers;
import play.*;
import play.mvc.*;
import twitter4j.TwitterException;
import twitter4j.TwitterFactory;
import twitter4j.auth.AccessToken;
import twitter4j.auth.RequestToken;
import twitter4j.conf.*;
import views.html.*;
import twitter4j.Twitter;
import java.io.*;
public class Application extends Controller {
public Result index() throws TwitterException {
ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
if (session("authToken") == null ) {
// configure
configurationBuilder.setOAuthConsumerKey(<MY_CONSUMER_KEY>);
configurationBuilder.setOAuthConsumerSecret(<MY_CONSUMER_SECRET>);
twitter4j.conf.Configuration configuration = configurationBuilder.build();
Twitter twitter = new TwitterFactory(configuration).getInstance();
try {
String callback = routes.Application.twitterLoginCallback().absoluteURL(request());
RequestToken requestToken = twitter.getOAuthRequestToken(callback);
session("requestToken", requestToken.getToken());
session("requestTokenSecret", requestToken.getTokenSecret());
return redirect(requestToken.getAuthorizationURL());
} catch(Exception ex) {}
} else {
configurationBuilder.setOAuthConsumerKey(<MY_CONSUMER_KEY>);
configurationBuilder.setOAuthConsumerSecret(<MY_CONSUMER_SECRET>);
configurationBuilder.setOAuthAccessToken(session("authToken"));
configurationBuilder.setOAuthAccessTokenSecret(session("authSecret"));
twitter4j.conf.Configuration configuration = configurationBuilder.build();
Twitter twitter = new TwitterFactory(configuration).getInstance();
twitter.updateStatus("Hello world!");
}
return ok(index.render());
}
public Result twitterLoginCallback() throws TwitterException {
Twitter twitter = new TwitterFactory ().getInstance();
twitter.setOAuthConsumer(<MY_CONSUMER_KEY>, <MY_CONSUMER_SECRET>);
AccessToken accessToken = new AccessToken(session("requestToken"), request().getQueryString("oauth_verifier"));
session("authToken", accessToken.getToken());
session("authSecret", accessToken.getTokenSecret());
return redirect(routes.Application.index());
}
}
