Python的Flask項目中獲取請求用戶IP地址 addr

服務器直接部署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中啓動Flask

這種情況下， 按照上面的代碼只能獲取到本服務器地址。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可以做點什麼

Flask獲取用戶的ip,查詢用戶的登錄次數,並且封ip
