problems using signpost with freelancer API

[gonzobrains]

Hi,

Is anyone out there using signpost with Freelancer's API? I think
there are a few issues that is preventing me from getting around this
401 issue I'm having.

At first I was getting "malformed packet" errors. I have since
overridden the DefaultOAuthProvider to specify "GET" instead of
"POST", as the Freelancer API's sample app seems to be using GET, from
what I can see via Wireshark:




import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

import oauth.signpost.AbstractOAuthProvider;
import oauth.signpost.basic.DefaultOAuthProvider;
import oauth.signpost.basic.HttpURLConnectionRequestAdapter;
import oauth.signpost.http.HttpRequest;
import oauth.signpost.http.HttpResponse;

public class FreelancerOAuthProvider extends DefaultOAuthProvider
{
private static final long serialVersionUID = 1L;

public FreelancerOAuthProvider(String requestTokenEndpointUrl,
String accessTokenEndpointUrl, String authorizationWebsiteUrl) {
super(requestTokenEndpointUrl, accessTokenEndpointUrl,
authorizationWebsiteUrl);
// TODO Auto-generated constructor stub
}

@Override
protected HttpRequest createRequest(String endpointUrl) throws
MalformedURLException,
IOException

{
HttpURLConnection connection = (HttpURLConnection) new
URL(endpointUrl).openConnection();
connection.setRequestMethod("GET");
connection.setAllowUserInteraction(false);

return new HttpURLConnectionRequestAdapter(connection);

}

}


The problem is, I still get an error. When I compare the packets in
Wireshark it looks as thought Freelancer's API sample places all the
OAuth parameters in the query string:

/RequestRequestToken/requestRequestToken.xml?
oauth_callback=oob&oauth_consumer_key=0a4861e74131de5b679aebaf99e5821c6a4a5baa&oauth_nonce=72&oauth_signature=7Rn80qXj9%2FxQMX6RZN59G
%2FjzcXk%3D&oauth_signature_method=HMAC-
SHA1&oauth_timestamp=1289071858&oauth_version=1.0

I don't see this in the URI signpost creates:

/RequestRequestToken/requestRequestToken.xml

I'm guessing this is because signpost places this stuff in the
Authentication Header, right?
