Python 调用的进程错误：命令'；（'；grep'；'；route'；）'；返回非零退出状态1

蟒蛇3
OSX 10.13.2

我正在尝试制作

FACEBOOK\u白名单

，以防止在收听

webhook

我正在获取IP地址。该命令非常简单，只需

whois

、

pipe

和

grep

问题：

def test():
    import subprocess
    ps = subprocess.Popen(
        ["whois", "-h", "whois.radb.net", "--", "'-i origin AS32934'"],
        stdout=subprocess.PIPE,
        stderr=subprocess.STDOUT
    )
    output = subprocess.check_output(('grep', 'route'), stdin=ps.stdout)
    ps.wait()

---------------------------------------------------------------------------
CalledProcessError                        Traceback (most recent call last)
<ipython-input-28-8d5c434d09bd> in <module>()
      5     stderr=subprocess.STDOUT
      6 )
----> 7 output = subprocess.check_output(('grep', 'route'), stdin=ps.stdout)
      8 ps.wait()

~/.pyenv/versions/3.6.4/lib/python3.6/subprocess.py in check_output(timeout, *popenargs, **kwargs)
    334
    335     return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,
--> 336                **kwargs).stdout
    337
    338

~/.pyenv/versions/3.6.4/lib/python3.6/subprocess.py in run(input, timeout, check, *popenargs, **kwargs)
    416         if check and retcode:
    417             raise CalledProcessError(retcode, process.args,
--> 418                                      output=stdout, stderr=stderr)
    419     return CompletedProcess(process.args, retcode, stdout, stderr)
    420

CalledProcessError: Command '('grep', 'route')' returned non-zero exit status 1.

回溯：

def test():
    import subprocess
    ps = subprocess.Popen(
        ["whois", "-h", "whois.radb.net", "--", "'-i origin AS32934'"],
        stdout=subprocess.PIPE,
        stderr=subprocess.STDOUT
    )
    output = subprocess.check_output(('grep', 'route'), stdin=ps.stdout)
    ps.wait()

---------------------------------------------------------------------------
CalledProcessError                        Traceback (most recent call last)
<ipython-input-28-8d5c434d09bd> in <module>()
      5     stderr=subprocess.STDOUT
      6 )
----> 7 output = subprocess.check_output(('grep', 'route'), stdin=ps.stdout)
      8 ps.wait()

~/.pyenv/versions/3.6.4/lib/python3.6/subprocess.py in check_output(timeout, *popenargs, **kwargs)
    334
    335     return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,
--> 336                **kwargs).stdout
    337
    338

~/.pyenv/versions/3.6.4/lib/python3.6/subprocess.py in run(input, timeout, check, *popenargs, **kwargs)
    416         if check and retcode:
    417             raise CalledProcessError(retcode, process.args,
--> 418                                      output=stdout, stderr=stderr)
    419     return CompletedProcess(process.args, retcode, stdout, stderr)
    420

CalledProcessError: Command '('grep', 'route')' returned non-zero exit status 1.

第二个是将字符串拆分为多个双引号字符串

In [48]: ps = subprocess.Popen(["whois", "-h", "whois.radb.net", "--", "'-i", "origin", "AS32934'"])

In [49]: %  No entries found for the selected source(s).
%  No entries found for the selected source(s).
%  No entries found for the selected source(s).

我错在哪里

更新：
@让·弗朗索瓦·法布

In [49]: ps = subprocess.Popen(["whois", "-h", "whois.radb.net", "--", "-i", "origin", "AS32934"])

In [50]: %% Attribute name after "-i" is invalid or unsupported.

参考文献：

您尝试引用最后一个aegument与

Popen

所做的引用是多余的。我无法测试，但您必须删除您插入的额外引号：

ps = subprocess.Popen(["whois", "-h", "whois.radb.net", "--", "-i origin AS32934"])

Popen

检测参数中是否有空格，并在需要时自动将其引用。添加更多引号会使

Popen

添加更多引号，并且命令的参数是错误的

除非您需要分别传递每个参数，但这样做的尝试也会失败，因为您在第一个和最后一个参数中留下了引号。但这并不能解决问题：

ps = subprocess.Popen(["whois", "-h", "whois.radb.net", "--", "'-i", "origin", "AS32934'"]# Wrong

应该是

ps = subprocess.Popen(["whois", "-h", "whois.radb.net", "--", "-i", "origin", "AS32934"]

---

它在“-i”之后出现了

%%属性名，该属性名无效或不受支持。

但它有输出列表。这一行有什么想法吗？当我把它与完整的程序导入子进程ps=subprocess.Popen（[“whois”、“-h”、“whois.radb.net”、“-”、“-I origin AS32934”]、stdout=subprocess.PIPE、stderr=subprocess.stdout）output=subprocess.check\u output（‘grep’、‘route’、stdin=ps.stdout）ps.wait（）放在一起时，这一行就不见了非常感谢：+1
