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("Twitter", function(request, response) {
	var urlLink = 'https://api.twitter.com/1.1/statuses/update.json';

	var postSummary = request.params.status;
	var status = oauth.percentEncode(postSummary);
	var consumerSecret = "<your_consumer_secret>";
	var tokenSecret = "<your_secret_token_here>";
	var oauth_consumer_key = "<your_oauth_consumer_key>";
	var oauth_token = "<your_oauth_token_here>";

	var nonce = oauth.nonce(32);
	var ts = Math.floor(new Date().getTime() / 1000);
	var timestamp = ts.toString();

	var accessor = {
		"consumerSecret": consumerSecret,
		"tokenSecret": tokenSecret
	};
	
	
	var params = {
		"status":postSummary,
		"oauth_version": "1.0",
		"oauth_consumer_key": oauth_consumer_key,
		"oauth_token": oauth_token,
		"oauth_timestamp": timestamp,
		"oauth_nonce": nonce,
		"oauth_signature_method": "HMAC-SHA1"
	};
	var message = {
		"method": "POST",
		"action": urlLink,
		"parameters": params
	};
	

	//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="<your_oauth_consumer_key>", oauth_nonce=' + nonce + ', oauth_signature=' + encodedSig + ', oauth_signature_method="HMAC-SHA1", oauth_timestamp=' + timestamp + ',oauth_token="<your_twitter_oauth_token_here>", 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 + ' , ' + httpResponse);
		}
	});
});

For getting timeline:

Parse.Cloud.define("Timeline", function(request, response) {
	var urlLink = 'https://api.twitter.com/1.1/statuses/home_timeline.json';

	var consumerSecret = "<your_consumer_secret>";
	var tokenSecret = "<your_secret_token_here>";
	var oauth_consumer_key = "<your_oauth_consumer_key>";
	var oauth_token = "<your_oauth_token_here>";

	var nonce = oauth.nonce(32);
	var ts = Math.floor(new Date().getTime() / 1000);
	var timestamp = ts.toString();

	var accessor = {
		"consumerSecret": consumerSecret,
		"tokenSecret": tokenSecret
	};
	
	
	var params = {
		"oauth_version": "1.0",
		"oauth_consumer_key": oauth_consumer_key,
		"oauth_token": oauth_token,
		"oauth_timestamp": timestamp,
		"oauth_nonce": nonce,
		"oauth_signature_method": "HMAC-SHA1"
	};
	var message = {
		"method": "GET",
		"action": urlLink,
		"parameters": params
	};
	

	//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: 'GET',
		url: urlLink,
		headers: {
			"Authorization": 'OAuth oauth_consumer_key="<your_oauth_consumer_key>", oauth_nonce=' + nonce + ', oauth_signature=' + encodedSig + ', oauth_signature_method="HMAC-SHA1", oauth_timestamp=' + timestamp + ',oauth_token="<your_twitter_oauth_token_here>", oauth_version="1.0"'
		},
		body: {
		},
		success: function(httpResponse) {
			response.success(httpResponse.text);
		},
		error: function(httpResponse) {
			response.error('Request failed with response ' + httpResponse.status + ' , ' + httpResponse);
		}
	});
});

For deleting a particular tweet:

Parse.Cloud.define("Timeline", function(request, response) {
	var urlLink = 'https://api.twitter.com/1.1/statuses/destroy/'+request.params.id+'.json';

	var consumerSecret = "<your_consumer_secret>";
	var tokenSecret = "<your_secret_token_here>";
	var oauth_consumer_key = "<your_oauth_consumer_key>";
	var oauth_token = "<your_oauth_token_here>";

	var nonce = oauth.nonce(32);
	var ts = Math.floor(new Date().getTime() / 1000);
	var timestamp = ts.toString();

	var accessor = {
		"consumerSecret": consumerSecret,
		"tokenSecret": tokenSecret
	};
	
	
	var params = {
		"oauth_version": "1.0",
		"oauth_consumer_key": oauth_consumer_key,
		"oauth_token": oauth_token,
		"oauth_timestamp": timestamp,
		"oauth_nonce": nonce,
		"oauth_signature_method": "HMAC-SHA1"
	};
	var message = {
		"method": "POST",
		"action": urlLink,
		"parameters": params
	};
	

	//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="<your_oauth_consumer_key>", oauth_nonce=' + nonce + ', oauth_signature=' + encodedSig + ', oauth_signature_method="HMAC-SHA1", oauth_timestamp=' + timestamp + ',oauth_token="<your_twitter_oauth_token_here>", oauth_version="1.0"'
		},
		body: {
		},
		success: function(httpResponse) {
			response.success(httpResponse.text);
		},
		error: function(httpResponse) {
			response.error('Request failed with response ' + httpResponse.status + ' , ' + httpResponse);
		}
	});
});
