Python的Flask项目中获取请求用户IP地址 addr

服务器直接部署Flask

import logging from flask import Flask, render_template, request # Initialize the Flask application app = Flask(__name__) # Default route, print user's IP @app.route('/') def index(): ip = request.remote_addr logging.debug(ip) return render_template('index.html', user_ip=ip) if __name__ == '__main__': app.run(host="0.0.0.0", port=80)

Docker中Nginx代理Gunicorn中启动Flask

这种情况下， 按照上面的代码只能获取到本服务器地址。需要使用werkzeug.middleware.proxy_fix

import logging from flask import Flask, render_template, request from werkzeug.middleware.proxy_fix import ProxyFix # Initialize the Flask application app = Flask(__name__) app.wsgi_app = ProxyFix(app.wsgi_app, num_proxies=1) # Default route, print user's IP @app.route('/') def index(): ip = request.remote_addr logging.debug(ip) return render_template('index.html', user_ip=ip)

查到IP可以做点什么

Flask获取用户的ip,查询用户的登录次数,并且封ip
