I am working in Play framework and I am trying to import yahoo contacts.
I have cleared the yahoo authentication api's to get the access_token and guid.
With that, when I try to import the contacts using http://social.yahooapis.com/v1/user/{guid}/contacts with the auth parameters, I am getting the connection timeout exception in my page and log.
When I paste the same contact url being generated through the code in the browser, I am getting as signature_invalid
I hope I have followed all the stuffs mentioned in the yahoo api dev notes to create the oauth_signature, but still I am not getting it.
Can anyone help me on this please?
Controller code for generating signature -
public class Yahoo {
private static String token = "";
private static String currentUrl = "";
private static String verifier = "";
private static String tokenSecret = "";
private static String accessToken = "";
private static String yahooGuid = "";

You are getting invalid signature when you copy and paste on the browser because you are not passing the oauth headers.
I strongly suggest you using a lib to do that, I have done the exact same thing with linkedin: http://geeks.aretotally.in/projects/play-framework-linkedin-module
You will find explanation and link to the source code.
Hope it helps.
Thank you, Felipe
