Question

我正在尝试打印UTF-8和cp866进程输出。

我的代码：

if "sendcmd " in message.text:
    command = message.text.replace("sendcmd ", "")
    process = os.popen(command)
    answer = process.read()
    #print(answer.decode('utf-8').encode('cp866'))
    by = bytes(answer, 'utf-8')
    print(type(by))
    print(repr(by))
    process.close()

在此之后我明白了：

<class 'bytes'>
b'b\'\\xe2\\x80\\x9c\\xd0\\xb1\\xd0\\x87\\xd2\\x90\\xd0\\xb5: \\xd0\\x8b\\xd0\\xb2\\xd0\\x87\\xd0\\xb0\\xc2\\xa0\\xd1\\x9e\\xc2\\xab\\xd2\\x90\\xc2\\xad \\xd0\\xb1\\xd0\\x81\\xd0\\x88\\xc2\\xad\\xc2\\xa0\\xc2\\xab \\xc2\\xa7\\xc2\\xa0\\xd1\\x9e\\xd2\\x90\\xd0\\xb0\\xd0\\xb8\\xd2\\x90\\xc2\\xad\\xd0\\x81\\xd0\\xbf \\xd0\\x87\\xd0\\xb0\\xc2\\xae\\xd0\\xb6\\xd2\\x90\\xd0\\xb1\\xd0\\xb1\\xd0\\xb3 "whatever.exe" \\xd0\\xb1 \\xd0\\x81\\xc2\\xa4\\xd2\\x90\\xc2\\xad\\xd0\\xb2\\xd0\\x81\\xd0\\xb4\\xd0\\x81\\xd0\\x84\\xc2\\xa0\\xd0\\xb2\\xc2\\xae\\xd0\\xb0\\xc2\\xae\\xc2\\xac 3720.\\n\'

我明白我需要将编码更改为cp866，但我不明白如何实现它=（

更新：此代码没有帮助：

uni = type(by), repr(by)
print(uni.encode('ascii', 'ignore'))

bytes

在内部，str使用from subprocess import Popen, PIPE if "sendcmd " in message.text: ... process = Popen(command, stdout=PIPE) answer = process.communicate()[0] # (stdout, stderr) print(answer.decode('cp866'))模块，您可能需要稍微更改os.popen参数。检查subprocess的{{3}}。

如何正确地将编码改为cp866？
