Question

当我想通过使用epext将我的操作打包到函数中时出现问题，以下是代码的样子，命令ifconfig在被打包到函数中时不会被执行，其中我做错了，如何将我的操作打包成函数？提前谢谢。

spawn ssh x.x.x.x

proc do_sth {} {
  send "ifconfig\r" # won't work
  expect "~\]\#" {exit 0}
}

expect {
  "*assword" { send "xxx\r"; exp_continue }
  "~\]\#" { do_sth }
  #"~\]\#" { 
  #  send "ifconfig\r"  # this would works fine
  #  expect "~\]\#" {exit 0}
  #}
}

您可以尝试使用spawn_id

发送配置

spawn ssh x.x.x.x
#After process creation the process id will be saved in 
#standard expect variable'spawn_id'
#Copying it to variable 'id'
set id $spawn_id

现在变量＆＃39; id＆＃39;持有对ssh进程的引用。我们可以很好地使用send和expect与spawn id。

#Now we are setting the spawn id to our ssh process to make sure 
#we are sending the commands to right process
#You can pass this variable 'id' as arg in 'do_sth'   
proc do_sth { id } {
    set spawn_id $id
    send "ifconfig\r"
    expect "~\]\#" {exit 0}
}

或者反过来如下，

 proc do_sth { id } {
    #This way is useful, when u want to send and expect to multiple process 
    #simultaneously.
    send -i $id "ifconfig\r"
    expect -i $id "~\]\#" {exit 0}
}

像往常一样，您只需按以下方式拨打电话即可。

do_sth $id

如何使用expect将我的操作打包到函数中
