Python?subprocess.Popen?實時輸出?stdout的解決方法(正確管道寫法)

更新時間：2023年07月18日 11:41:07 作者：墨痕訴清風(fēng)

這篇文章主要介紹了Python?subprocess.Popen實時輸出stdout正確管道寫法,本文給大家介紹的非常詳細，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值，需要的朋友可以參考下

解決方法：

p = subprocess.Popen(cmd, stdout=subprocess.PIPE, bufsize=1)
for line in iter(p.stdout.readline, b''):
    print line,
p.stdout.close()
p.wait()

實際弱口令我是這樣寫的

import subprocess     #Popen
proc = subprocess.Popen(medusaCMD, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=True)
for line in iter(proc.stdout.readline, 'b'):
    print line
    if not subprocess.Popen.poll(proc) is None:
        if line == "":
            break
proc.stdout.close()

記小的寫法

proc = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
try:
    while True:
        buff = proc.stdout.readline()
        print(buff)
        if buff == '' and proc.poll() != None:
            break
        else:
            .....
except Exception:
    data["status"] = -1
finally:
    return data

單次管道輸出寫法

方法一

# -*- coding: UTF-8 -*-
import re
import sys
import subprocess
from subprocess import Popen, PIPE, STDOUT
#docker_info = {"CONTAINER ID":"", "NAME":"", "CPU %":"", "MEM USAGE / LIMIT":"", \
#               "MEM %":"", "NET I/O":"", "BLOCK I/O":"", "PIDS":""}
docker_list = []
cmd = "docker stats -a --no-stream"
proc = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
try:
    buff = proc.communicate()
    stritem = buff[0]
    str_list = re.split(r'  +|\n', stritem)
    for i in range(8, len(str_list)-1):
        if i % 8 == 0:
            value = 0
            docker_info = {}
            docker_info["CONTAINER ID"] = str_list[i]
        else:
            value += 1
            if value == 1:
                docker_info["NAME"] = str_list[i]
            elif value == 2:
                docker_info["CPU %"] = str_list[i]
            elif value == 3:
                docker_info["MEM USAGE / LIMIT"] = str_list[i]
            elif value == 4:
                docker_info["MEM %"] = str_list[i]
            elif value == 5:
                docker_info["NET I/O"] = str_list[i]
            elif value == 6:
                docker_info["BLOCK I/O"] = str_list[i]
            elif value == 7:
                docker_info["PIDS"] = str_list[i]
                docker_list.append(docker_info)
                value = 0
    print docker_list
except Exception as e:
    print "error", e
    sys.exit(1)
    proc.stdout.close()

方法二（待測試）

import subprocess
from multiprocessing.dummy import Pool as ThreadPool
command = poc + ' -t ' + ip + ' -p ' + port
result = subprocess.getoutput(command)
if 'WARNING: SERVER IS VULNERABLE' in result:
    result = AAAAA
else:
    result = BBBBBB
