Python Flask get IP of user

Question

I am trying to log the IP address of a user whenever they submit a form so I can prevent them from submitting the same form twice, how can I achieve this?

Answer 1

With Flask, the request variable has a remote_addr that contains the IP address of the origin.

from flask import request

@app.route("/submit", methods=["GET"])
def submit():
    const userIP = request.remote_addr; # This is the IP address of the request.
