How to get binary post data in Django !nicely?
forgive me if this is a bit of a newbie question, I started to learn Django yesterday, and I'm trying not to get into bad habits, i.e. I am trying to do things "the django way" from the start.
I have a view that recieves binary data as a http post field. Now Django of course autoconverts my binary data to a unicode string.
My question is, how do I just get the raw binary data?
A couple of things occurred to me. Let request
be the request I'm processing.
- Using
request.raw_post_data
would involve parsing the data again - when appearantlyrequest.POST
actually stores raw data and I am actually just trying to get around the on-the-fly conversion (and besides, that is new in the development version). - Using base64 o开发者_Python百科r so to transfer the data would work, but seems like too much overhead when the data transfer itself is not the problem.
- doing
request.encoding="foo"
before getting that field (and reassigning afterwards) doesn't work either because I still get a unicode string, besides feeling like a bit of a dirty hack. Using"base64"
here (not as bad as for the transfer encoding) gives me anAssertionError
.
Thanks in advance for your ideas!
EDIT: To clarify - I am not talking about a classic file upload here, but as binary data stored in a POST field. I'd like to do it that way because the only way I want to interface with that view is via an upload script. Using a normal POST field makes both the client and the server much simpler in that case.
Some might say that storing binary data in a standard form field is a bad habit in some way :)
You could use standard library methods of Python to convert your string back to a binary representation.
Take a look at binascii — Convert between binary and ASCI
Posting before edit:
What about this piece of code (receiving data from a POST)
def handleFile(self, request):
file = request.FILES["file"]
destination = open('filename.ext', 'wb')
for chunk in file.chunks():
destination.write(chunk)
destination.close()
Works for me.
