OAuth2Resource

Express middleware for request authorization against OAuth2Server.

Usage

OAuth2Server requires protected resources (your API server) to be registered, and provides credentials for authenticating access token verification requests. Configure the module with an authorization server endpoint, resource_id, resource_secret, and scope, then use it as route specific middleware. Here's an example Express app.

// app dependencies
var express = require('express')
  , app = express();

// middleware config
var authorize = require('../index')({
  endpoint: 'https://HOST:PORT/access', 
  resource_id: RESOURCE_ID, 
  resource_secret: RESOURCE_SECRET,
  scope: SCOPE
});

// app config
app.configure(function () {
  app.use(express.bodyParser());
  app.use(app.router);

  // Error handler
  app.use(function (err, req, res, next) {
    var error = (err.errors)
      ? { errors: err.errors }
      : { error: err.message, error_description: err.description };
    res.send(err.statusCode || 500, error);
  });
});

// Protected route
app.get('/protected', authorize, function (req, res) {
  res.send('protected resource');
});

Requests to a protected endpoint require a Bearer token:

$ curl -v 'localhost:3001/protected' -H 'Authorization: Bearer e957468c922c97605aa9'

> GET /protected HTTP/1.1
> Host: localhost:3001
> Accept: */*
> Authorization: Bearer e957468c922c97605aa9
>
< HTTP/1.1 200 OK
protected resource
