title: Get Google Plus Url Share Count
body: <p>I have read tons of posts about how to do this and they all say to use:</p>
  
  <pre><code>gapi.client.setApiKey('AIzaSyCKSbrvQasunBoV16zDH9R33D88CeLr9gQ')
  gapi.client.rpcRequest('pos.plusones.get', 'v1', {
     nolog: true,
     id: "http://www.google.com/",
     source: "widget",
     userId: "@viewer",
     groupId: "@self"
  }).execute(function(resp) {
     console.log('count:', resp.result.metadata.globalCounts.count)
  });
  </code></pre>
  
  <p>rpcRequest no longer appears to be supported the accepted call is to .request but when using pos.plusone.get it just 404's.  Is there another URL to use? Is this no longer possible.  What Gives?</p>
