It is believed that many inexperienced people don't know what to do about how to use request to get the requested IP address in django. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Install third-party libraries

Pip install django-ipware

Called in view

General usage:

From ipware.ip import get_ip # Import package def view_test (request): ip = get_ip (request) # get request request IP

Copy

Site-packages/ipware/ip.py source code:

From .utils import is_valid_ipfrom. Import defaults as defsNON_PUBLIC_IP_PREFIX = tuple ([ip.lower () for ip in defs.IPWARE_NON_PUBLIC_IP_PREFIX]) TRUSTED_PROXY_LIST = tuple ([ip.lower () for ip in defs.IPWARE_TRUSTED_PROXY_LIST]) def get_ip (request, real_ip_only=False, right_most_proxy=False): "" Returns client's best-matched ip-address Or None "" best_matched_ip = None for key in defs.IPWARE_META_PRECEDENCE_ORDER: value = request.META.get (key, request.META.get (key.replace ('_','-'),''). Strip () if value is not None and value! ='': ips = [ip.strip () .lower () for ip in value.split (') ')] if right_most_proxy and len (ips) > 1: ips = reversed (ips) for ip_str in ips: if ip_str and is_valid_ip (ip_str): if not ip_str.startswith (NON_PUBLIC_IP_PREFIX): return ip_str If not real_ip_only: loopback = defs.IPWARE_LOOPBACK_PREFIX if best_matched_ip is None: best_matched_ip = ip_str elif best_matched_ip.startswith (loopback) and not ip_str.startswith (loopback): Best_matched_ip = ip_str return best_matched_ipdef get_real_ip (request Right_most_proxy=False): "" Returns client's best-matched `real`` externally- routable` ip-address, or None "" return get_ip (request, real_ip_only=True, right_most_proxy=right_most_proxy) def get_trusted_ip (request, right_most_proxy=False) Trusted_proxies=TRUSTED_PROXY_LIST): "Returns client's ip-address from `roomd` proxy server (s) or None"if trusted_proxies: meta_keys = ['HTTP_X_FORWARDED_FOR',' XanomalFORWARDEDFOR'] for key in meta_keys: value = request.META.get (key, request.META.get (key.replace ('_','-')) ) .strip () if value: ips = [ip.strip () .lower () for ip in value.split (' ')] if len (ips) > 1: if right_most_proxy: ips.reverse () for proxy in trusted_proxies: if proxy in ips [- 1]: return ips [0] return None

Copy

Purpose: save and access IP with decorator

Import refrom django.core.cache import cachefrom django.shortcuts import renderfrom ipware.ip import get_ipdef get_ipv4 (ip): "" get IPv4: param ip:: return: "" # IP patterns ipv4_re = r'(?: 25 [0-5] | 2 [0-4]\ d | [0-1]?\ d?\ d) (?:\.
