How can I register a POST body request in Flask?

I am using a flask server and I want to log every data request and header (so I can use it to test my server). I took the logger werkzeug with

    self._app.log = logging.getLogger('werkzeug')
    self._app.log.addHandler(RotatingFileHandler('log.txt', mode='w'))
    self._app.log.setLevel(logging.DEBUG)

But I don't understand how to change the format of the log to include request.data and request.headers, all I have is the default log

    127.0.0.1 - - [17/Feb/2015 17:09:43] "POST /helloworld HTTP/1.1" 200 -

You can record additional information for each request using a Flask.before_request

hook:



@app.before_request
def log_request_info():
    app.logger.debug('Headers: %s', request.headers)
    app.logger.debug('Body: %s', request.get_data())

How about creating a little helper method that you call in every controller in your flask app.

The helper method would be something like this:

def log_my_request_data(request_data):
   #this method will log this data


and then in all controllers, get request.data like this

from flask import request

request_data = request.data

and call log_my_request_data(request_data)
