[oauth] Re: invalid sinature problem

[John Kristian]

Here's a simpler way, which works for me.

import net.oauth.OAuth;
import net.oauth.OAuthAccessor;
import net.oauth.OAuthConsumer;
import net.oauth.OAuthProblemException;
import net.oauth.OAuthServiceProvider;
import net.oauth.client.OAuthClient;
import net.oauth.client.httpclient4.HttpClient4;
import net.oauth.http.HttpMessage;

public class YahooContacts {
  private static final String consumerKey = ...
  private static final String consumerSecret = ...
  public static void main(String[] args) throws Exception {
OAuthClient client = new OAuthClient(new HttpClient4());
OAuthAccessor accessor = new OAuthAccessor(
  new OAuthConsumer(
null,
consumerKey,
consumerSecret,
new OAuthServiceProvider(
  https://api.login.yahoo.com/oauth/v2/get_request_token;,
  https://api.login.yahoo.com/oauth/v2/request_auth;,
  https://api.login.yahoo.com/oauth/v2/get_token;)));
final String callback = oob;
try {
  client.getRequestToken(accessor, null,
OAuth.newList(OAuth.OAUTH_CALLBACK, callback));
  System.out.println(OAuth.addParameters(
accessor.consumer.serviceProvider.userAuthorizationURL,
OAuth.OAUTH_TOKEN, accessor.requestToken));
} catch (OAuthProblemException problem) {
  System.err.println(problem.getParameters().get(
HttpMessage.RESPONSE));
}
  }
}

The imports are available via Maven:

[oauth] Re: how to use erlang-oauth

[pablo]

I've looked at the couchdb code and it seems they copied part of
erlang-oauth
inseatd of using it as an app so it's hard to use it as an example.

If there is no better example I'll have to implement something simple
myself.

Thank you

  Can someone please show me how to start with this erlang lib

 There is an example mochiweb server 
 athttp://github.com/tim/erlang-oauth-examples,
 but that doesn't do things properly, i.e., you'd have to write quite
 a bit more code to make that into something you could use in a
 production website.

 Recently, Jason Davies integrated erlang-oauth with CouchDB (http://
 couchdb.apache.org/), so that would be a more realistic example.

  How do I generate the website Secret and how do I generate
  a Salt for users?

 However you like. If you want something unpredictable then i would
 suggest taking a look at the Erlang crypto library (http://erlang.org/
 doc/apps/crypto/), which can be used to generate random bytes.

 Hope that helps a bit.
