Hey Matt, try the code below. It works reliably for me.
Make sure you've included:
http://oauth.googlecode.com/svn/code/javascript/oauth.js
http://oauth.googlecode.com/svn/code/javascript/sha1.js
<script type="text/javascript">
var requestUrl = 'http://...';
var ck = '...';
var cks = '...';
var accessor = {consumerSecret: cks};
var message = {
method: "GET",
action: requestUrl,
parameters: [
['oauth_signature_method', 'HMAC-SHA1'],
['oauth_consumer_key', ck],
['oauth_version', '1.0'],
['xoauth_requestor_id', guid],
['format', 'json']
]
};
OAuth.setTimestampAndNonce(message);
OAuth.setParameter(message, "oauth_timestamp", OAuth.timestamp
());
OAuth.SignatureMethod.sign(message, accessor);
var finalUrl = OAuth.addToURL(message.action,
message.parameters);
</script>
