Can a django piston module create a restful webservice loadable image

Question

I am trying to reassure the server so that the image can be uploaded. Using django-piston, I can put, receive, publish information, but I don’t know how to upload the image.

Answer 1

to a large extent.

technically this is just an http post.

Answer 2

On the one hand, yes. If you have image data, you can mail it to a handler who knows how to process it; if you do it right, theoretically it should be available in request.FILES for your handler. Simple HTTP.

POST. . ( ).

:

class x_http_methodoverride_middleware():
    def process_request(self, request):
        if 'HTTP_X_HTTP_METHODOVERRIDE' in request.META:
            newMethod = request.META['HTTP_X_HTTP_METHODOVERRIDE']
            if 'PUT' == newMethod.upper():
                request.method = 'PUT'
                request.META['REQUEST_METHOD'] = 'PUT'
                request.PUT = request.POST                
            if 'DELETE' == newMethod.upper() or 'DEL' == newMethod.upper():
                request.method = 'DELETE'
                request.META['REQUEST_METHOD'] = 'DELETE'
                request.DELETE = request.POST
