Package Exports

recaptcha-v2

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (recaptcha-v2) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Setup

Before you can use this module, you must visit [reCAPTCHA] (http://www.google.com/recaptcha) to request a public and private API key for your domain.

Example Using Express

app.js:

var express  = require('express'),
    Recaptcha = require('recaptcha').Recaptcha;

var PUBLIC_KEY  = 'YOUR_PUBLIC_KEY',
    PRIVATE_KEY = 'YOUR_PRIVATE_KEY';

var app = express.createServer();

app.configure(function() {
    app.use(express.bodyParser());
});

app.get('/', function(req, res) {
    var recaptcha = new Recaptcha(PUBLIC_KEY, PRIVATE_KEY);

    res.render('form.jade', {
        layout: false,
        locals: {
            recaptcha_form: recaptcha.toHTML()
        }
    });
});

app.post('/', function(req, res) {
    var data = {
        remoteip:  req.connection.remoteAddress,
        response:  req.param("g-recaptcha-response"),
        secret: PRIVATE_KEY
    };
    var recaptcha = new Recaptcha(PUBLIC_KEY, PRIVATE_KEY, data);

    recaptcha.verify(function(success, error_code) {
        if (success) {
            res.send('Recaptcha response valid.');
        }
        else {
            // Redisplay the form.
            res.render('form.jade', {
                layout: false,
                locals: {
                    recaptcha_form: recaptcha.toHTML()
                }
            });
        }
    });
});

app.listen(3000);

views/form.jade:

form(method='POST', action='.')
  != recaptcha_form

  input(type='submit', value='Check Recaptcha')

Make sure express and jade are installed, then:

$ node app.js
