Meteor reCAPTCHA v2
This is an implementation of the Google reCAPTCHA v2 API (i.e. "I'm not a robot") for Meteor sites. reCAPTCHA is a free CAPTCHA service provided by Google that authenticates real users while attempting to block bots.
reCAPTCHA is at https://developers.google.com/recaptcha/
Package is an upgraded version of Meteor-reCAPTCHA provided by Altapp (https://github.com/Altapp/Meteor-reCAPTCHA).
Installation
$ meteor add ayue:recaptchaSetup
Obtain reCAPTCHA Keys From Google
Register at https://www.google.com/recaptcha/admin to obtain your private and public key needed for reCAPTCHA to function.
On The Client
Add your reCAPTCHA public key (from Google) to the package. Do this in client-side code.
Meteor.startup(function() {
reCAPTCHA.config({
publickey: 'your_public_key_from_google'
});
});On The Server
Add your reCAPTCHA private key (from Google) to the package. Do this in server-only code (not just an 'isServer' block) to keep your key secret.
Meteor.startup(function() {
reCAPTCHA.config({
privatekey: 'your_private_key_from_google'
});
});Usage
On The Client
Include the {{> reCAPTCHA}} template block in your form template.
<template name="myTemplate">
<form>
<!-- your form fields... -->
{{> reCAPTCHA}}
<button type="submit">Submit</button>
</form>
</template>In your submit event, include the reCAPTCHA data in your method call.
Template.myTemplate.events({
'submit form': function(e) {
e.preventDefault();
var formData = {
//get the data from your form fields
};
//get the captcha data
var recaptchaResponse = grecaptcha.getResponse();
Meteor.call('formSubmissionMethod', formData, recaptchaResponse, function(error, result) {
if (error) {
console.log('There was an error: ' + error.reason);
} else {
console.log('Success!');
}
});
}
});On The Server
In the server method, pass the captcha data and the user's IP address to reCAPTCHA.verifyCaptcha(recaptchaResponse, clientIP) to verify that the user entered the correct text.
Meteor.methods({
formSubmissionMethod: function(formData, recaptchaResponse) {
var verifyCaptchaResponse = reCAPTCHA.verifyCaptcha(recaptchaResponse, this.connection.clientAddress);
if (!verifyCaptchaResponse.success) {
console.log('reCAPTCHA check failed!', verifyCaptchaResponse);
throw new Meteor.Error(422, 'reCAPTCHA Failed: ' + verifyCaptchaResponse.error);
} else
console.log('reCAPTCHA verification passed!');
//do stuff with your formData
return true;
}
});
