Why not?

from flask import Flask, request

app = Flask(__name__)

@app.before_request
def log_request():
    app.logger.debug("Request Headers %s", request.headers)

# The remaining application code.

I've used the headers but you can use the same aproach to print any request attribute. The docs are here: http://flask.pocoo.org/docs/0.12/api/#flask.Request.

Also you need to setup FLASK_DEBUG=1 to Flask.logger.debug to work, what is nice since you can disable it in production.
