通过播放框架将yahoo联系人导入到我的页面所需的帮助

Question

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 = "";


public Yahoo(){
}

    if(session.contains("authorized") && session.get("authorized").equals("0")){
        session.put("authorized", "1");
        String url = getRequestTokenUrl();

        WS.WSRequest request = WS.url(url);
        Logger.info("Yahoo: Create request to get request token'%s'", request.url);

        WS.HttpResponse response = request.get();
        Logger.info("Yahoo: Token response status is %d", response.getStatus());

        if (response.getStatus() == 200){
            String[] pairs = response.getString().split("&");
            String[] tokenSecret = pairs[1].split("=");

            Yahoo.tokenSecret = tokenSecret[1];

            for (String pair : pairs) {
                String[] kv = pair.split("=");
                if (kv.length != 2) {

Answer 1

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
