    <p>Reason given for failure:</p>
    <pre>
    CSRF cookie not set.
    </pre>
    

  <p>In general, this can occur when there is a genuine Cross Site Request Forgery, or when
  <a
  href="https://docs.djangoproject.com/en/1.10/ref/csrf/">Django's
  CSRF mechanism</a> has not been used correctly.  For POST forms, you need to
  ensure:</p>

  <ul>
    <li>Your browser is accepting cookies.</li>

    <li>The view function passes a <code>request</code> to the template's <a
    href="https://docs.djangoproject.com/en/dev/topics/templates/#django.template.backends.base.Template.render"><code>render</code></a>
    method.</li>

    <li>In the template, there is a <code>{% csrf_token
    %}</code> template tag inside each POST form that
    targets an internal URL.</li>

    <li>If you are not using <code>CsrfViewMiddleware</code>, then you must use
    <code>csrf_protect</code> on any views that use the <code>csrf_token</code>
    template tag, as well as those that accept the POST data.</li>

    <li>The form has a valid CSRF token. After logging in in another browser
    tab or hitting the back button after a login, you may need to reload the
    page with the form, because the token is rotated after a login.</li>
  </ul>

  <p>You're seeing the help section of this page because you have <code>DEBUG =
  True</code> in your Django settings file. Change that to <code>False</code>,
  and only the initial error message will be displayed.  </p>

  <p>You can customize this page using the CSRF_FAILURE_VIEW setting.</p>

とエラーが出ました。これはSwift側を直せば良いのでしょうか？それともPython側を直せば良いのでしょうか？
