请写一个python脚本功能如下使用nmap扫描1901680024 网段的开放开放端口要求多线程处理tcp端口1-65535udp端口1-65535结果保存到MongoDB数据库

以下是一个实现上述功能的Python脚本：

import nmap
import pymongo
import threading

# MongoDB连接参数
MONGO_HOST = 'localhost'
MONGO_PORT = 27017
MONGO_DB = 'port_scanner'
MONGO_COLLECTION = 'scan_results'

# 扫描目标网段
TARGET_NETWORK = '190.168.0.0/24'

# 创建MongoDB连接
mongo_client = pymongo.MongoClient(MONGO_HOST, MONGO_PORT)
db = mongo_client[MONGO_DB]
collection = db[MONGO_COLLECTION]

# 创建互斥锁，用于保护数据库操作
lock = threading.Lock()

# 扫描指定IP的开放端口
def scan_port(ip):
    scanner = nmap.PortScanner()
    scanner.scan(ip, '1-65535', arguments='-T4 -Pn')
    tcp_ports = scanner[ip].all_tcp()
    udp_ports = scanner[ip].all_udp()
    result = {
        'ip': ip,
        'tcp_ports': tcp_ports,
        'udp_ports': udp_ports
    }
    with lock:
        collection.insert_one(result)
    print(f'Scan result for {ip} saved to MongoDB.')

# 多线程扫描
def multi_thread_scan():
    threads = []
    for host in TARGET_NETWORK:
        t = threading.Thread(target=scan_port, args=(host,))
        threads.append(t)
        t.start()
    for t in threads:
        t.join()

# 主函数
if __name__ == '__main__':
    multi_thread_scan()
    mongo_client.close()

请确保已安装nmap和pymongo模块，并将脚本中的MongoDB连接参数适配为您的实际情况
