我有一个愿望脚本,它会产生,期望和发送并获得所需的数据。 当我按照愿望ex.tcl运行脚本时,它不起作用。
请查看以下代码以获取更多信息。
#!/usr/bin/wish
package require Expect
proc openSession { targetHost } {
log_user 1
set user $::env(USER)
set password "tmp1234"
set timeout 60
set spawn_id ""
puts "Ssh to $user@$targetHost"
spawn ssh -o UserKnownHostsFile=/dev/null $user@$targetHost
match_max -i $spawn_id 99999
expect {
"\(yes\/no\)\? " { send "yes\r" ; exp_continue }
"password\:" { puts 2 ; send "$password\r" ; exp_continue }
"$ " { puts 3 ; send "\r" ; puts "Ssh Session ready" }
timeout { puts 4 ; set spawn_id "" ; puts "Timeout during ssh $targetHost" }
}
set timeout 10
return $spawn_id
}
proc closeSession { sshSess args } {
puts "Closing Ssh session..."
expect -i $sshSess "$ " { send -i $sshSess "exit\r" }
expect -i $sshSess "closed." { puts "Connection Closed" }
catch { exp_close -i $sshSess }
catch { exp_wait -i $sshSess }
return
}
set sessId [openSession testbng76]
grid [ttk::button .mybutton -text Mytext]
closeSession $sessId
看到错误:
Are you sure you want to continue connecting (yes/no)? Error in startup script: wrong # args: should be "send ?options? interpName arg ?arg ...?"
while executing
"send "yes\r" "

如何使用tk生成远程会话并获得所需的输出?
答案 0 :(得分:4)
Tk 还有一个send
命令用于与其他启用Tk的解释器进行通信(它以与Expect完全不同的方式工作)并且两者相互作用。或者更确切地说,Expect在看到Tk时退出,并且不会创建send
命令。
幸运的是,您可以使用exp_send
代替;它是您想要的功能的另一个名称,Expect始终创建它。例如:
"\(yes\/no\)\? " { exp_send "yes\r" ; exp_continue }
