问题
I do a request to my local server using postman like this:
As you can see it's a post request. In my view (APIView) I need access to the json data. But when I try:
request.POST
# <QueryDict: {}>
or
request.data # ¿?
# AttributeError: 'WSGIRequest' object has no attribute 'data'
The only way I can see the sent data is when I access to
request.body
# '{\n "token": "6J3qG4Ji2Jw44eIklKvPYxUgclfGRWHZDKG",\n "city": "Port Orange",\n "state": "FL",\n "formatted_address": "Peach Blossom Blvd 5329",\n "_zip": "32128"\n}'
But this is a 'str'
>>> type(request.body)
<type 'str'>
I an trying to access to the request's data in dispatch() method. I can do this:
req = self.initialize_request(request)
This returns a rest_framework.request.Request object and I can access to request data. But then I can't call
super(FaveoAPIView, self).dispatch(request, *args, **kwargs)
Because I get:
{
"status_code": 400,
"object": "Malformed request.",
"success": false
}
I can'r understand why, I guess that when I call self.initialize_request() something change. Any idea?
回答1:
I believe you should be able to override the initial() method on your view in order to achieve what you're attempting. The docstring from the APIView class reads:
"""
Runs anything that needs to occur prior to calling the method handler.
"""
So, it would look something like:
class FaveoAPIView(APIView):
def initial(self, request, *args, **kwargs):
super(FaveoAPIView, self).initial(request, *args, **kwargs)
# Manipulate request.data to your heart's content here
In APIView, this is called immediately before your method handler.
回答2:
super(FaveoAPIView, self).dispatch(request, *args, **kwargs) will call initialize_request turning the request into a DRF one. This can only be once therefore it'll fail after that.
Instead of fixing a broken solution, could you rather tell us about your actual issue, i.e. why you need to access the requests data before the view itself is called ?
