OAuth 1.1 Header/Signature Generator, js library for Parse Cloud code

Javascript library for Oauth 1.1 Header & signature generation (Twitter mainly),.

Orginal Source code: https://code.google.com/p/oauth (http://oauth.googlecode.com/)

How To Do

1). Upload oauth.js,sha1.js into Parse cloud

2). Add the following code at the top of your main.js

			var oauth = require('cloud/oauth.js');
			var sha = require('cloud/sha1.js');

Sample Code

For Twitter posting.

Parse.Cloud.define("ShareToTwitter", function(request, response){
	var urlLink = 'https://api.twitter.com/1.1/statuses/update.json';
	
	var postSummary="<Add-post-summary>";
	var status = oauth.percentEncode(postSummary);
	var consumerSecret = "<add-the-consumer-secret-of-twitter-application>";
	var tokenSecret = "<add-the-access-token-secret-of-user>";
	var oauth_consumer_key = "<add-the-consumer-key-of-twitter-app>";
	var oauth_token = "<add-the-auth-token-of-user>";
	
    var nonce = oauth.nonce(32);
    var ts = Math.floor(new Date().getTime() / 1000);
    var timestamp = ts.toString();
    
    var accessor = {"consumerSecret" : consumerSecret, "tokenSecret":tokenSecret};
    var message = {"method" : "POST", "action": urlLink, "parameters":oauth.decodeForm("status="+status)};
    message.parameters.push(["oauth_version","1.0"]);
    message.parameters.push(["oauth_consumer_key", oauth_consumer_key]);
    message.parameters.push(["oauth_token", oauth_token]);
    message.parameters.push(["oauth_timestamp",timestamp]);
    message.parameters.push(["oauth_nonce", nonce]);
    message.parameters.push(["oauth_signature_method", "HMAC-SHA1"]);
    
    //lets create signature
    oauth.SignatureMethod.sign(message, accessor);
    var normPar = oauth.SignatureMethod.normalizeParameters(message.parameters);
    console.log("Normalized Parameters: "+normPar);
    var baseString = oauth.SignatureMethod.getBaseString(message);
    console.log("BaseString: "+baseString);
    var sig = oauth.getParameter(message.parameters, "oauth_signature")+"=";
    console.log("Non-Encode Signature: "+sig);
    var encodedSig=oauth.percentEncode(sig); //finally you got oauth signature
    console.log("Encoded Signature: "+encodedSig);

 Parse.Cloud.httpRequest({
    method: 'POST',
    url: urlLink,
    headers: {
        "Authorization": 'OAuth oauth_consumer_key="xxxxxxxxxxxxxxxxx", oauth_nonce='+nonce+', oauth_signature='+encodedSig+', oauth_signature_method="HMAC-SHA1", oauth_timestamp='+timestamp+',oauth_token="xxxxxxxxxxxxxxxxxxxxxxx", oauth_version="1.0"'
   },
   body: {
  	 "status" : postSummary,      
   },
   success: function(httpResponse) {
  	 response.success(httpResponse.text);
   },
   error: function(httpResponse) {
    	response.error('Request failed with response' + httpResponse.status);
   }
 });
});
