Oauth Module for Parse Cloud Code

This is a modified version of node-oauth.

How to use

1. Copy all the files to your project's cloud folder.

2. Use it in your main.js code like so (Note: This is an example of calling Yahoo! BOSS API from Parse Cloud Code)

    var webSearchUrl = 'http://yboss.yahooapis.com/ysearch/images';
    
    var qs = require('qs');
    var finalUrl = webSearchUrl + '?' + qs.stringify({
    	q: encodeURIComponent(request.params.keyword),  //search keywords
    	format: 'json',
    	count: 30,
    });
   
    var OAuth = require('cloud/oauth').OAuth;
    var consumerKey = '<YOUR_CONSUMER_KEY';
    var consumerSecret = '<YOUR_CONSUMER_SECRET>';
    var oa = new OAuth(webSearchUrl, webSearchUrl, consumerKey, consumerSecret, "1.0", null, "HMAC-SHA1");
    oa.setClientOptions({ requestTokenHttpMethod: 'GET' });
   
    var orderedParameters= oa._prepareParameters('', '', 'GET', finalUrl, null);
    var headers= {};
    var authorization = oa._buildAuthorizationHeaders(orderedParameters);
    headers["Authorization"]= authorization;
   
    Parse.Cloud.httpRequest({
    	url: finalUrl,
    	headers: headers,
    	success: function(httpResponse) {
    		var json = JSON.parse(httpResponse.text);
    		var images = json.bossresponse.images.results;
    		response.success(images);
    	},
    	error: function(httpResponse) {
    		response.error('Request failed with response code ' + httpResponse.text);
    	}
    });
   

Note

1. https doesn't work. If you can make it work, please let me know.
2. HMAC-SHA1 signature method only.
