Question

我正在尝试使用AsyncSSH模块执行命令并捕获输出以进行进一步处理。我遵循了official documentation上的示例，但是它们都将结果打印（），我想将其保存为列表。如何在Python 3.5中做到这一点？我试图通过添加将返回“退出”列表的getdata（）来修改类，但是它似乎不起作用

import asyncio, asyncssh, sys


class MySSHClientSession(asyncssh.SSHClientSession):

    out = []

    def data_received(self, data, datatype):
        if datatype == asyncssh.EXTENDED_DATA_STDERR:
            print(data, end='', file=sys.stderr)
        else:
            #print(data, end='')
            self.out.append(data)

    def connection_lost(self, exc):
        if exc:
            print('SSH session error: ' + str(exc), file=sys.stderr)

    def getdata(self):
        return self.out


async def run_client(zone, cmd):
    async with asyncssh.connect(zone, password='xxx', username='xxx', known_hosts=None) as conn:
        chan, session = await conn.create_session(MySSHClientSession, cmd)
        await chan.wait_closed()

try:
    x = asyncio.get_event_loop().run_until_complete(run_client('fetish', 'sudo fl-service status'))
# the code to process x would go here
    print(x.getdata())
except (OSError, asyncssh.Error) as exc:
    sys.exit('SSH connection failed: ' + str(exc))

AsyncSSH将输出保存到Python中的列表
