如何一次又一次地阻止同一设备的发生

from flask import Flask, request, jsonify
from flask_limiter import Limiter
from flask_limiter.util import get_remote_address
import hashlib

app = Flask(__name__)

# 使用IP地址进行速率限制
limiter = Limiter(
    get_remote_address,
    app=app,
    default_limits=["200 per day", "50 per hour"]
)

# 设备指纹识别
def generate_device_fingerprint():
    user_agent = request.headers.get('User-Agent')
    screen_resolution = request.headers.get('Screen-Resolution')
    hardware_id = request.headers.get('Hardware-ID')
    fingerprint_data = f"{user_agent}{screen_resolution}{hardware_id}"
    return hashlib.sha256(fingerprint_data.encode()).hexdigest()

# 模拟设备访问记录
device_access_records = {}

@app.route('/access', methods=['GET'])
@limiter.limit("10 per minute")
def access_resource():
    device_fingerprint = generate_device_fingerprint()
    if device_fingerprint in device_access_records:
        return jsonify({"error": "Device has exceeded access limit"}), 429
    else:
        device_access_records[device_fingerprint] = True
        return jsonify({"message": "Access granted"}), 200

if __name__ == '__main__':
    app.run(debug=True)
