Laravel 4 Yahoo Contacts API Integration
<?php
/**
* Author: Kenyon Haliwell
* Date: 10/22/14
*
* Used to authenticate with Yahoo via oAuth2 and then use their Contacts API to return emails.
*
* Step 1: send user to Yahoo@getContactsLink
* Step 2: return user to a route that calls Yahoo@getContactsArray
* Step 3: Whatever you wanted to do with the contacts
*
* Note: If using Laravel 4 I put this under app/models/oauth2/Yahoo.php
* Note: You can use this with any framework/code, just follow these couple steps:
* Step 1: Remove namespace
* Step 2: Change \Auth::user()->id to logged in users ID
* Step 3: Change \Input::get('thing') to $_GET['thing']
* Step 4: Change Session::put/Session::get/Session::pull to $_SESSION (add key=>value, get value, get value and unset)
* Step 5: Use like a regular class.
