无法将 2 个变量传递给预期；字符串索引必须是整数，而不是 str

Question

正在尝试从无线控制器中提取数据。命令是 show ap auto-rf 频段可以是 802.11a 802.11b 或 802.11-abgn ap-name 是任意的

示例输出：

（思科控制器）>show ap auto-rf 802.11-abgn Hallway38

Number Of Slots.................................. 2 
AP Name.......................................... Hallway38
MAC Address...................................... a0:e0:af:33:d0:bc
  Slot ID........................................ 0
  Radio Type..................................... RADIO_TYPE_80211abgn
  Current TX/RX Band............................. 80211 2.4G band
  Sub-band Type.................................. All
  Noise Information
    Noise Profile................................ PASSED
    Channel 1....................................  -90 dBm
    Channel 2....................................  -77 dBm
    Channel 3....................................  -88 dBm
    Channel 4....................................  -93 dBm
    Channel 5....................................  -91 dBm
    Channel 6....................................  -88 dBm
    Channel 7....................................  -93 dBm

错误输出：文件“./wlc-auto-rf.py”，第 34 行，位于 child.sendline ('show ap auto-rf' ['radio']['apname']) 类型错误：字符串索引必须是整数，而不是 str

感谢任何帮助。

here is the script:
              !/usr/bin/python 
              #
              #       requires python pexpect module
              #
              import pexpect
              import sys
             firstarg=sys.argv[0]
             address=sys.argv[1]
             username=sys.argv[2]
             password=sys.argv[3]
             radio=sys.argv[4]
             apname=sys.argv[5]
             output=sys.argv[6]

      child = pexpect.spawn ('ssh' , [address])
      child.expect ('User:')
      child.sendline (username)
      child.expect ('Password:')
      child.sendline (password)
      child.expect ("Controller")
      child.sendline ('config paging disable')
      #
      child.expect ("Controller")
      child.sendline ('show ap auto-rf' ['radio']['apname'])
      child.logfile = open(output , "w")
      child.expect ("Controller")
      child.sendline ('logout')
      child.expect('(y/N)')
      child.sendline ('N')
      child.expect(pexpect.EOF)

Answer 1

我能够使用字符串连接将变量一起添加到一个字符串中来修复它 child.sendline ('show ap auto-rf '+radio+' '+apname)

无法将 2 个变量传递给预期；字符串索引必须是整数，而不是 str

Having trouble passing 2 variables to pexpect; string indices must be integers, not str

python

ssh

pexpect
