Omniauth Strategy for iHealth

This is a strategy to connect with iHealth using Ommniauth and OAuth 2.0. Originally written by ArturKarbone, up to date as of Feb 13, 2014 for iHealth's API.

You can apply for API access on iHealth's developer website here.

Installing

Add to your Gemfile:

gem 'omniauth-ihealth', :git=>'https://github.com/hspinks/omniauth-ihealth.git'

Then bundle install.

Usage

OmniAuth::Strategies::IHealth is a Rack middleware. Read the OmniAuth docs for detailed instructions: https://github.com/intridea/omniauth

Here's a quick example, adding the middleware to a Rails app in config/initializers/omniauth.rb:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :ihealth, ENV['KEY'], ENV['SECRET']
end

Configuring

You can configure several options, which you pass in to the provider method via a Hash:

scope: A list of permissions you want to request from the user, separated by spaces. Options are OpenApiUserInfo, OpenApiActivity, OpenApiBG, OpenApiBP, OpenApiSleep, OpenApiSpO2, and OpenApiWeight. You must include OpenApiUserInfo. Defaults to OpenApiUserInfo.
sc: The Serial Code for the client. You can find this on the developer detail page on iHealth's website here.
sv: The SV value listed for OpenApiUserInfo on the developer detail page.

Auth Hash

		"name" => "John Doe",
		"nickname" => "John Doe",
		"image" => "https://cloud.ihealthlabs.com/logos/12345.png"

	"credentials" => {
		"token" => "ABCDEF...", # OAuth 2.0 access_token
		"refresh_token" => "ABCDEF...",
		"expires_at" => 1392501884,
		"expires" => true
	},
	"extra" => {
		"user_info" => {
			"name" => "John Doe",
			"gender" => "male",
