title: GoogleCloud: With service account credentials, how to access all files under directory ? How to get SignedUrl for entire directory?
body: <p>Google Cloud:
  I have stored some files under <code>xyz</code> folder which is under <code>ABC</code> bucket. We have created service account to access those files. I am able to create signed URL for each file with <code>gsutil</code>:</p>
  
  <pre><code>gsutil signurl -d 120s key.json gs://bucketname/folderNmae/index.html
  </code></pre>
  
  <p>Instead of creating <code>signedURL</code> for all files I want to access directly folder.
  Do we have any solution to do that?</p>
  
  <p>Tried creating <code>signedURL</code> for folder but got error:</p>
  
  <blockquote>
    <p>Please create/upload an object with that name before a creating signed URL to access it.</p>
  </blockquote>
