title: Drupal 8.x POST (create) node via REST doesn't work
body: <p>I am working with Drupal 8.0 alpha 11. I've been able to follow the Drupal guides for REST services:</p>
  
  <p>POST for creating content entities (<a href="https://drupal.org/node/2098511" rel="nofollow">https://drupal.org/node/2098511</a>) and the related guides, GET on content entities and GET on Views-generated lists</p>
  
  <p>"GET"s work great, but I haven't been able to get any "POST" to work (I've posted the issue on the drupal.org site, too).</p>
  
  <p>I've tested POST for both a basic page and my own content entity and neither works. I've tried a lot of variations, including removing "entity" from the url as per the recent changes in Drupal 8, but the POST still does not work. I'm using Postman in Chrome for testing and again, I can "GET" a basic page and my own content entity just fine, but with POST, I always get a return code of 200 "OK", never "201" (which is what I should receive according to the guide) and the nodes don't get created.</p>
  
  <p>I've updated the rest.settings.yml for both the basic page and my content type, have established permissions for the user, am using basic auth, and have added Content Type application/hal+json and cross-origin details to the header info.</p>
  
  <p>Any idea what's missing? Do I need to add coding in my create entity form to "receive" the posted data? Where do I do this/in which directories should the files go? Is this required for the default Basic Page content type, too?</p>
  
  <p>Thanks for any help...I've spent weeks on this and can't figure out what I'm missing.</p>
  
  <p>Thank you!</p>
