title: download a file from google cloud storage with the api
body: <p>I currently use gsutil cp to download files from my bucket but that requires you to have a bunch of stuff installed.</p>
  
  <p>I just want to download it using a simple API request like:</p>
  
  <pre><code>http://storage.googleapis.com/mybucket/pulltest/pulltest.csv
  </code></pre>
  
  <p>This gives me access denied. How are the auth parameters formatted to bypass this? </p>
