代码未上传，但在控制台中打印

Question

我已经编写了这段代码，它应该上传一些东西，但它不上传任何东西，只是在我的控制台中打印命令的结果，并且不上传任何东西到网站

import requests, os, re, subprocess
from bs4 import BeautifulSoup

command = 'netsh interface ip show addresses "Ethernet" | findstr /c:IP'
outcome = str(subprocess.Popen(command, shell=True).wait())
#soup = BeautifulSoup(outcome,'lxml')

#outcome = outcome.replace('0','')

#print str(subprocess.call(command, shell=True))

requests.post("example.com", {'field1': outcome})

和控制台输出：

IP Address:                           192.168.1.23

上传到网站0

我试过了：

import requests, os, re, subprocess
from bs4 import BeautifulSoup

command = 'netsh interface ip show addresses "Ethernet" | findstr /c:IP'
#subprocess.communicate(command, shell=True)
subprocess.Popen(command, shell=True).communicate()
outcome = subprocess.PIPE
#soup = BeautifulSoup(outcome,'lxml')

#outcome = outcome.replace('0','')

#print str(subprocess.call(command, shell=True))

requests.post("example.com", {'field1': outcome})

和控制台输出：

IP Address:                           192.168.1.23

哪些上传到网站-1

我想要它做的是将该 IP 地址结果上传到网站。

您没有正确使用子流程。我建议你使用subprocess.Popen.communicate，并传入stdout=subprocess.PIPE 来实际获取子进程的stdout。

p = subprocess.Popen(["my", "command"], stdout=subprocess.PIPE)
stdout, _ = p.communicate()
