Empty request.POST after upgrade to Django 1.3

问题

The following code works fine under Django 1.2 but fails under Django 1.3 because request.POST is empty, although the form data is posted correctly to the server

def commit_form(request):
    logging.debug(str(datetime.datetime.now()) + ": commit data " + request.raw_post_data)
    purchase = Purchase.objects.get(transaction_id=request.POST['TransactionID']) #breaks here, request.POST is empty

    #other stuff...

    return HttpResponse("GOOD", mimetype="text/plain")

Why does this not work, I can't see any error here?

回答1:

I recall having a problem of this kind, it turned out that accessing request.raw_post_data prevented the request.POST dict from being subsequently populated with the post params. What happens if you remove the logging.debug line?

回答2:

I had a similar problem (empty request.POST) with django 1.3, but it was due to a bug in my HTML.

I had a form with action="foo" but my urls.py mapped "foo/" to the view (where I was expecting some POST data, and getting none). Django kindly server-side redirects requests for "foo" to "foo/", but the POST data was not being resubmitted to "foo/" as part of the deal. In hindsight that seems quite sensible. Changing my form (to action="foo/") fixed it, I suppose changing the urls.py could have worked too.

Also check your content type header.

Eg.

'CONTENT_TYPE': 'application/x-www-form-urlencoded'

Earlier versions were more accommodating if this header was missing or invalid.
