Question

这是我的代码：

def cmdoutput(cmd1, flag):
    finish = time.time() + 50
    p = subprocess.Popen(cmd1, stdin=subprocess.PIPE, stdout = subprocess.PIPE, stderr=subprocess.STDOUT, shell=True)
    while p.poll() is None:
        time.sleep(1)
        if finish < time.time():
            os.kill(p.pid, signal.SIGTERM)
            print "timed out and killed child, collecting what output exists so far"
        if (flag == "1"):#To enable container
            out, err = p.communicate(input='container\nzone1')
    else:
        out, err = p.communicate()
    print (out)
    return out

当我运行此脚本时，我得到了

Attribute Error: 'module' object has no attribute 'kill'.

我的代码出了什么问题？

Answer 1

我认为你有自己的os.py。

将print os.__file__放在os.kill(...)行之前，您将看到发生了什么。

<强>更新

os.kill is only available in unix in jython

而不是os.kill(...)，请使用p.kill()。

<强>更新

p.kill()不起作用。（至少在Windows + Jython 2.5.2,2.5.3中）。

p.pid为无。

Answer 2

更改您的代码如下。更改CPYTHON_EXECUTABLE_PATH，CMDOUTPUT_SCRIPT_PATH。

CPYTHON_EXECUTABLE_PATH = r'c:\python27\python.exe' # Change path to python.exe
CMDOUTPUT_SCRIPT_PATH = r'c:\users\falsetru\cmdoutput.py' # Change path to the script

def cmdoutput(cmd1, flag):
    return subprocess.check_output([CPYTHON_EXECUTABLE_PATH, CMDOUTPUT_SCRIPT_PATH, flag])

将以下代码保存为cmdoutput.py

import subprocess
import sys

def cmdoutput(cmd1, flag):
    finish = time.time() + 50
    p = subprocess.Popen(cmd1, stdin=subprocess.PIPE, stdout = subprocess.PIPE, stderr=subprocess.STDOUT, shell=True)
    while p.poll() is None:
        time.sleep(1)
        if finish < time.time():
            p.kill()
            return '<<timeout>>'
        if flag == "1":
            out, err = p.communicate('container\nzone1')
    else:
        out, err = p.communicate()
    return out

if __name__ == '__main__':
    cmd, flag = sys.argv[1:3]
    print(cmdoutput(cmd, flag))

AttributeError：'module'对象没有属性'kill'
