body: <p>I have create a user role in Magento 2 and a new user 
  <a href="http://i.stack.imgur.com/sPb2u.png" rel="nofollow">image capture</a></p>
  
  <p>I used in Chrome the application Postman:</p>
  
  <p>In the GET box: <a href="http://example.com/php.index/rest/V1/products/" rel="nofollow">http://example.com/php.index/rest/V1/products/</a>
  In Type use Basic Auth with Username and Password</p>
  
  <p>But I get this status '401 Unauthorized' and this requests:</p>
  
  <pre><code>    {
    "message": "Consumer is not authorized to access %resources",
    "parameters": {
      "resources": "Magento_Catalog::products"
    }
  }
  </code></pre>
  
  <p>I can login in Magento backend with the user and password</p>
  
  <p>Any solution?</p>
