application that uses OAuth and javascript

Question

I am planning to create an app that uses JavaScript and it needs to use OAuth to authenticate user for a website. Can anyone help me out please? Any sample code? I know about the Google Code Javascript OAuth library but I am not sure how to implement that..

Answer 1

Post your question to OAuth Google group. You will get more responses there.

Many people don't agree with me but I don't think OAuth is suitable for Javascript. There is no way to keep consumer secret in the browser. OAuth should be implemented in a server.

Answer 2

There is a JS client implementation for OAuth here: http://oauth.googlecode.com/svn/code/javascript/

It contains example code to get you running. Basically, what you do is this:

var url = "...";
var accessor = {
  token: "...",
  tokenSecret: "...",
  consumerKey : "...",
  consumerSecret: "..."
};

var message = {
  action: url,
  method: "GET",
  parameters: {...}
};

OAuth.completeRequest(message, accessor);        
OAuth.SignatureMethod.sign(message, accessor);
url = url + '?' + OAuth.formEncode(message.parameters);

// send request to 'url'
...
