Take some time to read through the code and the comments. Don't forget to fill in the keys you
received from Twitter in the
CONSUMER_KEY
and
CONSUMER_SECRET
variables. Note also the
REQUEST_TOKEN_URL
,
AUTHORIZE_URL
, and
ACCESS_TOKEN_URL
variables, containing the OAuth
URLs provided to you earlier by Twitter.
Execute this code in Eclipse; you'll see the following output:
Request Token:
- oauth_token = QEaZwniqkgRcB25gAuGGQg7rHz48OR5a8uoZ3AJs
- oauth_token_secret = scnIHqN59V0WAe2nyEoxiOWRejcBA7WPmQv5Ah5Q
Go to the following link:
QEaZwniqkgRcB25gAuGGQg7rHz48OR5a8uoZ3AJs
Enter the verification PIN provided by Twitter:
(Your tokens will differ.) Open the given link in your web browser. A Twitter page will appear ask-
ing you if you want to allow access to an external application. See Figure 10-21.
Press Authorize App. Next, Twitter will provide you with a PIN that you'll need to provide to the
application. See Figure 10-22.
Go back to the running Eclipse console, enter the PIN, and press Enter. The program will resume
and execute the REST call:
Enter the verification PIN provided by Twitter:
2162766
Access Token:
- oauth_token = 9807092-pEFWjo4juyL3MhZ1IruqvUeq1bvbpb83ZcDGCBtVEB
- oauth_token_secret = QlG4enz5Zo4YKMXq6Pv4kgoLFH5x7cLBZpHsYshhNynwz

Note
If you had set a callback URL, Twitter would not provide a PIN but
would refer the user back to an URL you specify with the access token pro-
vided as an URL parameter, which your application can then intercept auto-
matically. Since setting up web servers with Java hasn't been covered yet, here
you can use the PIN‐based approach.
