如何在Node中发送OAuth请求？

是否有模块/库来生成请求标头？我期望的功能如下：

var httprequest = createRequest(url,method,consumer_key,token);

我正在使用下面的代码.

var OAuth = require('oauth').OAuth;

consumer = new OAuth('http://term.ie/oauth/example/request_token.PHP','http://term.ie/oauth/example/access_token.PHP','key','secret','1.0',null,'HMAC-SHA1');

// Get the request token                    
consumer.getOAuthRequestToken(function(err,oauth_token,oauth_token_secret,results ){
    console.log('==>Get the request token');
    console.log(arguments);
});


// Get the authorized access_token with the un-authorized one.
consumer.getOAuthAccessToken('requestkey','requestsecret',function (err,results){
    console.log('==>Get the access token');
    console.log(arguments);
});

// Access the protected resource with access token
var url='http://term.ie/oauth/example/echo_api.PHP?method=foo&bar=baz';
consumer.get(url,'accesskey','accesssecret',data,response){
    console.log('==>Access the protected resource with access token');
    console.log(err);
    console.log(data);
});
