Question

我正在尝试使用python telnetlib自动执行任务。这是我的代码：

    import telnetlib
    t = telnetlib.Telnet(self._ip_addr)
    # t.connect()

    if not t.expect(["User Name : "], timeout=10):  # Expect username prompt
        raise Exception('No login prompt is received')

    t.write(self._username + '\r\n')  # Send username

    if not t.expect(["Password  : "], timeout=10):  # Expect password prompt
        raise Exception('No password prompt is received')

    t.write(self._password + '\r\n')  # send password

    t.set_debuglevel(1)

    if not t.read_until("apc>", timeout=10):  # Expect prompt
        raise Exception('No command prompt is received')

    import time
    time.sleep(2)

    t.write("vt100\n")
    t.write("olOff 9\n")
    # t.close()

此代码的输出如下：

Telnet(10.130.210.71,23): recv '*'
Telnet(10.130.210.71,23): recv '****'
Telnet(10.130.210.71,23): recv '*'

Telnet(10.130.210.71,23): send 'vt100\n'
Telnet(10.130.210.71,23): send 'olOff 9\n'

我正在Windows上执行此代码。这里的问题是最后一个命令没有被执行。

任何人都可以建议我在哪里做错了吗？

评论中的答案，结尾缺少：

t.read_until("apc>", timeout=10)

telnetlib telnet.write（）未按预期工作
