将变量传递给子进程 [英] Pass variable to subprocess

问题描述

我正在尝试构建一个命令，其中包含一个包含 IP 地址的变量到 subprocess 但未传递变量.

I am trying to construct a command which includes a a variable containing IP addresses to a subprocess but the variable is not passed.

iplist

8.8.8.8
1.1.1.1

代码

with open('iplist', 'r', encoding="utf-8") as f:
    data = f.read()
    print(data)
    cmd = ['./mmdbinspect', '--db', '/usr/local/var/GeoIP/GeoLite2-City.mmdb', '$data']
    result = subprocess.run(cmd, stdout=subprocess.PIPE)
    print(result.stdout)

输出

8.8.8.8
1.1.1.1
2020/11/01 10:06:13 could not get records from db /usr/local/var/GeoIP/GeoLite2-City.mmdb: $data is not a valid IP address
b''

推荐答案

类似的东西

with open('iplist', 'r', encoding="utf-8") as ip_file:
    for ip in ip_file:
      cmd = ['./mmdbinspect', '--db', '/usr/local/var/GeoIP/GeoLite2-City.mmdb', ip.strip()]
      result = subprocess.run(cmd, stdout=subprocess.PIPE)
      print(result.stdout)
