Question

External django redirect with POST parameters

Answer 1

+2 A:

GET parameters always go in the URL, that's what makes them GET parameters.

It is not possible to redirect using POST parameters (which don't go in the URL) - this is a restriction of HTTP, not Django.

Does that mean it's not possible to redirect to a payment site/window, without the user being able to see all the data being sent along?

Answer 2

+3 A:

I suggest the following approach. In your Django view/template return form to the browser with all the parameters that you want to post as hidden form elements. As soon as the form loads the JavaScript will submit (POST) form to where ever you want.

View:

from django.shortcuts import render_to_response

def view(request):
    return render_to_response('test.html', { 'foo': 123, 'bar': 456 })

Template:

<html>
<head>
    <title>test</title>
     <script type="text/javascript">
     function load()
     {
          window.document.test.submit();
          return;
     }
     </script>
</head>
<body onload="load()">
<form name="test" method="post" action="http://www.example.com"&gt;
    <input type="hidden" name="foo" value={{ foo }} />
    <input type="hidden" name="bar" value={{ bar }} />
</form>
</body>
</html>

That's a clever way to avoid the redirect. However, this is javascript dependent so would need to make a graceful degradation also. I wonder how smooth this will be in practice though, having to load the page before being able to do the js post.

Yes this solution depends on JavaScript being enabled in the browser, but it doesn't mean that you need to do it right on this page. You should check for JavaScript before you even get to your view. So that if it is not enabled then user would not even get this far. As for the loading of the page, it would depend on how quick your view returns, and how big is the result HTML. If you only have a couple fields the rendering of the page I am guessing would be in sub-second time. The redirection itself is quick too, so the user experience with this solution is very similar to a normal redirect.
