Can not read request.body from a POST request

[Mihai Corciu]

Is there a method to access request.body from a POST request in Django, without disabling 'django.middleware.csrf.CsrfViewMiddleware' ?

CsrfViewMiddleware is causing:

Exception Type:     RawPostDataException
Exception Value:     You cannot access body after reading from request's data stream

which means request.body is impossible to acces without disabling CsrfViewMiddleware.

Why would you want to access request.body directly? You should use request.POST, request.GET, request.FILES.

Vijay: They are not the same thing. request.POST, .GET and .FILES are exactly that, POST and GET data and the optional uploaded files. However, in e.g. a RESTful environment it is possible to have something else in the request body.

Mihai, what else do you do with the request before trying to read its body?

Best,

Gergely

What could be in the body that's not in the supplied Django fields?

I have implemented RESTful APIs as you say (no idea why that matters as they are just HTTP requests) and never had the need to read the actual body..

A JSON/XML payload, for example. If you use plain Django (on DRF and other extensions), then request.body is the only way to access said payload.

This should not be happening. CsrfViewMiddleware is enabled by default and does not interfere with reading request.body. Please post the full traceback.

Yeah, I was wrong, I actually use request.body in my code without problem with the default middlewares enabled.

First, I wanted to process multiple file upload because I could not read all files but just one. I resolved it another way , but request.body coud not be read. Maybe it's not useful or maybe I will have need sometime this. I think it is a limitation that I coud not read it just in case. I attached an entire test with this.

This request.body exist so , normally , must be readable.
Thanks.

Error says : You cannot access body after reading from request's data stream and CsrfViewMiddleware is accessing before the post request. I disabled it and it worked but this is not a safe solution.
Django docs confirm that:

Accessing request.POST inside middleware from process_request or process_view will prevent any view running after the middleware from being able to modify the upload handlers for the request, and should normally be avoided.

The CsrfViewMiddleware class can be considered an exception, as it provides the csrf_exempt() and csrf_protect() decorators which allow views to explicitly control at what point the CSRF validation should occur.

https://docs.djangoproject.com/en/dev/topics/http/middleware/

So request.body could not be read without disabling csrf middleware.
I attached an example with that situation.
Thanks.
