# 示例代码：使用Python Flask框架结合WAF中间件
from flask import Flask, request
app = Flask(__name__)

@app.before_request
def limit_remote_addr():
    # 限制单个IP地址每分钟最多请求100次
    ip = request.remote_addr
    if ip in request.environ.get('RATE_LIMIT'):
        if request.environ['RATE_LIMIT'][ip] > 100:
            return "Too Many Requests", 429
        request.environ['RATE_LIMIT'][ip] += 1
    else:
        request.environ['RATE_LIMIT'][ip] = 1

@app.route('/')
def index():
    return "Hello, World!"

# 示例代码：使用Flask和reCAPTCHA
from flask import Flask, render_template, request
import requests

app = Flask(__name__)

@app.route('/')
def index():
    return render_template('index.html')

@app.route('/verify', methods=['POST'])
def verify():
    captcha_response = request.form['g-recaptcha-response']
    secret_key = 'YOUR_SECRET_KEY'
    response = requests.post('https://www.google.com/recaptcha/api/siteverify', data={
        'secret': secret_key,
        'response': captcha_response
    })
    if response.json().get('success'):
        return "Verified!"
    else:
        return "Failed!"
