Viki Disqus Gem

This is a gem used by the Viki web application for integrating Disqus Single Sign-On (SSO). Users who log in to Viki can post comments on Disqus using the same Viki account, without the need for another login.

Add this line to your application's Gemfile:

gem 'viki_disqus'

And then execute:

$ bundle

Or install it yourself as:

$ gem install viki_disqus

NOTE: You will have to read http://help.disqus.com/customer/portal/articles/236206-integrating-single-sign-on for setup instructions on the Disqus end.

You need to set these 2 environment variables to appropriate values:

• DISQUS_SECRET_KEY
• DISQUS_PUBLIC_KEY

They will be used by the VikiDisqus::SSO class. Their values can be accessed through:

• VikiDisqus::SSO::DISQUS_SECRET_KEY
• VikiDisqus::SSO::DISQUS_PUBLIC_KEY

These functions are available publicly:

• VikiDisqus::SSO::remote_auth_s3(optionsHash, timestampNow)
• VikiDisqus::SSO::signature(optionsHash, timestampNow)
• VikiDisqus::SSO::message(optionsHash)

You should make use of the VikiDisqus::SSO::remote_auth_s3 function (which uses VikiDisqus::SSO::signature and VikiDisqus::SSO::message internally).

You will need to embed this snippet of JavaScript, according to instructions from Disqus. The template looks like:

var disqus_config = function () {
    // The generated payload which authenticates users with Disqus
    this.page.remote_auth_s3 = '<message> <hmac> <timestamp>';
    this.page.api_key = 'public_api_key';
}

On the Viki web application, it looks like:

var disqus_config = function () {
  this.page.remote_auth_s3 = '<%= VikiDisqus::SSO.remote_auth_s3(opts, Time.now.to_i) %>';
  this.page.api_key = '<%= VikiDisqus::SSO::DISQUS_PUBLIC_KEY %>';
}
