Description
This ticket if for implementing a request parsing API that ensures the Request
objects can nicely handle JSON and other submitted types in addition the the existing multipart parsing.
The proposed API is based on this discussion: https://groups.google.com/forum/#!searchin/django-developers/request.DATA/django-developers/s8OZ9yNh-8c/oCbNL5x6avAJ
request.DATA
orrequest.data
for accessing the parsed data.request.parsers
or similar for modifying the parsers prior to parsing on a per-view basis.request.accepted_parser
or similar for branching on media type if needed.- A setting
REQUEST_PARSERS
or similar, that controls the default set of installed parsers.

or this is the HTTP Handling part only? view parts will be implemented differently in another ticket? serialization in another part? hope you don't get me wrong for asking too many questions.

These 3 issues are related.
[1] https://code.djangoproject.com/ticket/21442
[2] https://code.djangoproject.com/ticket/28678
[3] https://github.com/encode/django-rest-framework/issues/4881
[1] is the overall tracker for this issue, desires to create a configurable parser. Opened 9 years ago.
[3] describes the desired behavior with example. Opened 5 years ago.
[2] has a proposed fix (credit: Facundo Batista). The fix is simple and worked well when I tried it. Opened 5 years ago.
Surely a configurable parser [1] is a good goal to pursue. But if it
takes 9 years before anything happens, perhaps we can take [2]? It is
not configurable, but it works well.
re: a case for multipart parser that can handle json parts
I have an api that takes some json input, plus 2 optional image files.
With json parser, I cannot easily include image files (base64 works, but
clumsy for modest size images).
Multipart parser allows me to send the json input plus images in 1
call. But all the data parts are treated as text (str). One of the
data field is a dict (eg. { "x": 7, "y": 5 }).
If I use json parser, it is an dict (good).
If I use multipart parser, it becomes a str (bad; desired to get a
dict).

Following thread on mailing list, we're going to approach by adding the request.data
part, adding just JSON handling, before making the accepted content types pluggable as a second step.
Beginning work over here. Not yet ready.
Related to #32259 to modernise the request object at the same time.

OK, this didn’t make it in GSoC. I’m going to pick this back up.

https://github.com/django/deps/blob/master/draft/content-negotiation.rst
reading the DEP
my thoughts are wouldn't it better/nicer to handle the content negotiation per view based content negotiation? and there should be decorators to handle content negotiation in view level?
+ is it really necessary to introduce new global settings?
