google-api-php-client - 驱动器 - 文件插入 - 创建文本文件 - 未添加内容

Question

I want to create a plain/text Mime Type file, using PHP and the Google-API for Google Drive on Google App Engine.

When I use:

'mimeType' => 'text/plain',

No content is written to the file.

If I use:

'mimeType' => 'application/octet-stream',
'uploadType' => 'media'

contents are added to the file.

This code from Google documentation:

Shows a line of code for the mimeType of 'text/plain'

'mimeType' => 'text/plain',

But, again, if I use that, no contents are added to the file. What are the settings for creating a plain text file and adding content?

My complete code is this:

<?php
/* You can NOT see the files created in a Service Account without doing some special stuff.  You need to set some kind
of permissions, and then you can see the files in your SHARED WITH ME section of Google Drive

$client_id = 'your Client ID'; //Client ID

   if ($downloadUrl) {

    }
  } else {
    // The file doesn't have any content stored on Drive.
    echo 'The file doesnt have any content stored on Drive. <br>';
  }
}

echo "File Upload - Uploading a small file".'<br>';

<?php

If you want a text file with that MimeType, create it from PHP not directly on Drive. That's why that mimetype isn't getting recognized. fopen() can do the trick.
