hello,
i been told to open this thread here: oauth forums

i have a desktop application that will fetch user email from his yahoo account.
i wrote this POC but i keep getting 500 error.

CODE

function getYahooEmails(){
	var aParams		= [{'fid':'inbox','startInfo':0,'numInfo':10}];
	var oRequest	= {'method':'ListMessages','params': aParams};
	var sRequest	= json_encode(oRequest); //i took json_encode from here: http://phpjs.org/functions/json_encode:457
	var sUrl		        = 'http://mail.yahooapis.com/ws/mail/v1.1/jsonrpc';
	var sHeader		= 'OAuth oauth_nonce="f65670481f2282ddc82607e148de374a",oauth_timestamp="1272050828",oauth_version="1.0",oauth_signature_method="HMAC-SHA1",oauth_consumer_key="MYKEY",oauth_token="TOKEN",oauth_signature="SIG"'; //this value is from my  web page application
	var oAjax		= new XMLHttpRequest();
	oAjax.open("POST",sUrl,true);
	oAjax.setRequestHeader("Content-Type", "application/json");
	oAjax.setRequestHeader("Accept", "application/json");
	oAjax.setRequestHeader("Authorization", sHeader);
	oAjax.setRequestHeader("Connection", "close");
	oAjax.onreadystatechange=function(){
		if(oAjax.readyState != 4) return;
		if(oAjax.status != 200) return;		
		document.getElementById('result').innerText = oAjax.responseText;
	}
	oAjax.send(sRequest);
}

i use fiddler
this is the request header:

note: i have no cross domain issue with ajax as this is from "localhost" to yahoo servers.

what is the problem?
do you guys have a working ajax/jsonp snippet that is working?

thanks
