Re: Access request body in the django.request logger

Well my last reply was preemptery.

A minimal working example can be produced via the following commands. First navigate to a suitable directory then,

# virtualenv venv --no-site-packages

# source venv/bin/activate

# pip install django

# django-admin startproject mwe

# vim mwe/mwe/settings.y

and then entering the following at the end of the settings.py file:

LOGGING = {                                                                          

    'version': 1,                                                                    

    'disable_existing_loggers': False,                                               

    'formatters': {                                                                  

        'django.server': {                                                           

            '()': 'django.utils.log.ServerFormatter',                                

            'format': '[%(server_time)s] %(message)s %(request)r',                   

        }                                                                            

    },                                                                               

    'handlers': {                                                                    

        'django.server': {                                                           

            'level': 'INFO',                                                         

            'class': 'logging.StreamHandler',                                        

            'formatter': 'django.server',                                            

        },                                                                           

    },                                                                               

    'loggers': {                                                                     

        'django.server': {                                                           

            'handlers': ['django.server'],                                           

            'level': 'INFO',                                                         

            'propagate': False,                                                      

        },                                                                           

    }                                                                                

}

Then :wq

# cd mwe

# python manage.py runserver

Navigate to http://127.0.0.1:8000/blargh

The normal error message about routing will show. Switch back to the console and you'll see:

# python manage.py runserver

Django version 1.10.1, using settings 'mwe.settings'

Starting development server at http://127.0.0.1:8000/

Quit the server with CONTROL-C.

Not Found: /blargh

[15/Sep/2016 23:12:09] "GET /blargh HTTP/1.1" 404 1918 <socket._socketobject object at 0x7fa14d58da60>

That representation of the socket object is being produced by the "%(request)r" in the formatter.

Chasing this back through the call stack the request object is set in /usr/lib/python2.7/SocketServer.py(652)__init__() as the socket. This is seems reasonable to me, so I guess some kind of processing of the request isn't being performed somewhere.

Thanks for the reply Tim

Some testing seems to indicate that it is an issue with django-rest-framework. When I contact the web server using urls managed by django rest the issues occurs, when I do the same via url managed by vanilla django the request variable in the context object is an instance of WSGIRequest, which is far more sensible.

I'm doing to do some more digging today to prove this and, assuming I'm right, will pass the bug onto the django rest guys.

Any hints on debugging this? I haven't entered the django code base much before.

If true, it does seem like a bug. Could you provide a test for Django's test suite or a sample project to reproduce it?

Hi 

What I'd like to do is log the request body whenever the django.request logger logs something. I had assumed that the extra context referred to as request in https://docs.djangoproject.com/en/1.10/topics/logging/#django-request was something like an HTTPRequest object. It is, however, an instance of socket._socketobject.

Is it possible to get data for logging using the socket? For example the get parameters, the post data, any information associated to a file that was sent like what every has been read out of the socket? What about the request headers?

Why is a socket passed to the logger? I must admit that I assume this to be a bug. The user has a very limited way of interacting with the socket via the string formatting syntax and the methods of the socket (as introspected via dir) don't lend them selves to this form of access.

I'm currently using django 1.10 if that helps.

Thanks for any help.
