oauth-1.0a

OAuth 1.0a Request Authorization for Node and Browser

Send OAuth request with your favorite HTTP client (request, jQuery.ajax...)

No more headache about OAuth 1.0a's stuff or "oauth_consumer_key, oauth_nonce, oauth_signature...." parameters, just use your familiar HTTP client to send OAuth requests.

Tested on some popular OAuth 1.0a services:

• Twitter
• Flickr
• Bitbucket
• Linkedin
• Openbankproject(HMAC-SHA256)

Quick Start

var oauth = OAuth({
    consumer: {
        public: '<your consumer key>',
        secret: '<your consumer secret>'
    }
});

Get OAuth request data then you can use with your http client easily :)

oauth.authorize(request, token);

Or if you want to get as a header key-value data

oauth.toHeader(oauth_data);

##Installation

###Node.js $ npm install oauth-1.0a

##Examples

###Work with request (Node.js)

Depencies

var request = require('request');
var OAuth   = require('oauth-1.0a');

Init

var oauth = OAuth({
    consumer: {
        public: 'xvz1evFS4wEEPTGEFPHBog',
        secret: 'kAcSOqF21Fu85e7zjz7ZN2U4ZRhfV3WpwPAoE3Z7kBw'
    },
    signature_method: 'HMAC-SHA1'
});

Your request data

var request_data = {
    url: 'https://api.twitter.com/1/statuses/update.json?include_entities=true',
    method: 'POST',
    data: {
        status: 'Hello Ladies + Gentlemen, a signed OAuth request!'
    }
};

Your token (optional for some requests)

var token = {
    public: '370773112-GmHxMAgYyLbNEtIKZeRNFsMKPR9EyMZeS9weJAEb',
    secret: 'LswwdoUaIvS8ltyTt5jkRh4J50vUPVVHtR2YPi5kE'
};

Call a request

request({
    url: request_data.url,
    method: request_data.method,
    form: oauth.authorize(request_data, token)
}, function(error, response, body) {
    //process your data here
});

Or if you want to send OAuth data in request's header

request({
    url: request_data.url,
    method: request_data.method,
    form: request_data.data,
    headers: oauth.toHeader(oauth.authorize(request_data, token))
}, function(error, response, body) {
    //process your data here
});

###Work with jQuery.ajax (Browser)

Caution: please make sure you understand what happen when use OAuth protocol at client side here

Init

var oauth = OAuth({
    consumer: {
        public: 'xvz1evFS4wEEPTGEFPHBog',
        secret: 'kAcSOqF21Fu85e7zjz7ZN2U4ZRhfV3WpwPAoE3Z7kBw'
    },
    signature_method: 'HMAC-SHA1'
});

Your request data

var request_data = {
    url: 'https://api.twitter.com/1/statuses/update.json?include_entities=true',
    method: 'POST',
    data: {
        status: 'Hello Ladies + Gentlemen, a signed OAuth request!'
    }
};

Your token (optional for some requests)

var token = {
    public: '370773112-GmHxMAgYyLbNEtIKZeRNFsMKPR9EyMZeS9weJAEb',
    secret: 'LswwdoUaIvS8ltyTt5jkRh4J50vUPVVHtR2YPi5kE'
};

Call a request

$.ajax({
    url: request_data.url,
    type: request_data.method,
    data: oauth.authorize(request_data, token)
}).done(function(data) {
    //process your data here
});

Or if you want to send OAuth data in request's header

$.ajax({
    url: request_data.url,
    type: request_data.method,
    data: request_data.data,
    headers: oauth.toHeader(oauth.authorize(request_data, token))
}).done(function(data) {
    //process your data here
});

##.authorize(/* options */)

• url: String
• method: String default 'GET'
• data: Object any custom data you want to send with, including extra oauth option oauth_* as oauth_callback, oauth_version...

var request_data = {
    url: 'https://bitbucket.org/api/1.0/oauth/request_token',
    method: 'POST',
    data: {
        oauth_callback: 'http://www.ddo.me'
    }
};

##.toHeader(/* signed data */)

convert signed data into headers

$.ajax({
    url: request_data.url,
    type: request_data.method,
    data: request_data.data,
    headers: oauth.toHeader(oauth.authorize(request_data, token))
}).done(function(data) {
    //process your data here
});

##Init Options

var oauth = OAuth(/* options */);

• consumer: Object Required your consumer keys

{
    public: <your consumer key>,
    secret: <your consumer secret>
}

• signature_method: String default 'HMAC-SHA1'
• nonce_length: Int default 32
• version: String default '1.0'
• parameter_seperator: String for header only, default ', '. Note that there is a space after ,
• last_ampersand: Bool default true. For some services if there is no Token Secret then no need & at the end. Check oauth doc for more information

oauth_signature is set to the concatenated encoded values of the Consumer Secret and Token Secret, separated by a '&' character (ASCII code 38), even if either secret is empty

##Notes

• Some OAuth requests without token use .authorize(request_data) instead of .authorize(request_data, {})

• Or just token public only .authorize(request_data, {public: 'xxxxx'})

• Want easier? Take a look:

  • Node.js: oauth-request
  • jquery: soon

##Client Side Usage Caution

OAuth is based around allowing tools and websites to talk to each other. However, JavaScript running in web browsers is hampered by security restrictions that prevent code running on one website from accessing data stored or served on another.

Before you start hacking, make sure you understand the limitations posed by cross-domain XMLHttpRequest.

On the bright side, some platforms use JavaScript as their language, but enable the programmer to access other web sites. Examples include:

• Google/Firefox/Safari extensions
• Google Gadgets
• Microsoft Sidebar...

For those platforms, this library should come in handy.
