import json import subprocess with open('eve.json', 'r') as f: events = json.load(f) for event in events: if event['alert']['severity'] <= 2: ip = event['src_ip'] # 调用iptables命令封禁IP subprocess.call(['iptables', '-A', 'INPUT', '-s', ip, '-j', 'DROP'])输出一个封禁成功的结果，完善代码

可以在调用 `subprocess.call` 命令后，再进行一个判断，看是否执行成功，完善代码如下：

import json
import subprocess

with open('eve.json', 'r') as f:
    events = json.load(f)

for event in events:
    if event['alert']['severity'] <= 2:
        ip = event['src_ip']
        # 调用iptables命令封禁IP
        result = subprocess.call(['iptables', '-A', 'INPUT', '-s', ip, '-j', 'DROP'])
        if result == 0:
            print(f'封禁IP {ip} 成功！')
        else:
            print(f'封禁IP {ip} 失败！')

这样，当 `subprocess.call` 命令执行成功时，会输出一个封禁成功的结果，否则输出一个封禁失败的结果。
