关于expect脚本输出的问题

写了一个expect脚本 执行ssh命令远程登录 然后telnet另外一台机器

大致如下：

 #!/usr/bin/expect -f
 set timeout
 set port_type [lindex $argv ]
 set p1 [lindex $argv ]
 set p2 [lindex $argv ]
 set p3 [lindex $argv ]
 set p4 [lindex $argv ]
 set p5 [lindex $argv ]

 if { $port_type eq "http" } {
     #puts "{\"retcode\":\"0\",\"retinfo\":\"in-http\"}"
     #puts "port_type=$port_type p1=$p1  p2=$p2  p3=$p3  p4=$p4  p5=$p5  p6=$p6"
     spawn ssh $p2@$p1
     expect_after eof { exit  }

     expect "yes/no" { send "yes\r" }
     expect "*assword:" { send "$p3\r" }

     #spawn
     #expect "Welcome" { send "telnet $p4 $p5\r" }
     expect "*#" { send "telnet $p4 $p5\r" }
     expect "Connected to" { puts "{\"retcode\":\"0\",\"retinfo\":\"success\"}"
                             exit
             }
     puts "{\"retcode\":\"-2\",\"retinfo\":\"fail\"}"

 } elseif { $port_type eq "mysql" } {
     set p6 [lindex $argv ]
     set p7 [lindex $argv ]
     #puts "{\"retcode\":\"0\",\"retinfo\":\"in-mysql\"}"
     #puts "port_type=$port_type p1=$p1  p2=$p2  p3=$p3  p4=$p4  p5=$p5  p6=$p6 p7=$p7"
     spawn ssh $p2@$p1
     expect_after eof { exit  }

     expect "yes/no" { send "yes\r" }
     expect "*assword:" { send "$p3\r" }

     expect "Welcome" { send "mysql -h $p4 -P $p5 -u $p6 -p $p7\r" }
     expect "#" { send "mysql -h $p4 -P $p5 -u $p6 -p $p7\r" }
     expect "$" { send "mysql -h $p4 -P $p5 -u $p6 -p $p7\r" }

     expect "Welcome to the MySQL" {
             puts "{\"retcode\":\"0\",\"retinfo\":\"success\"}"
             exit
             }
     puts "{\"retcode\":\"-2\",\"retinfo\":\"fail\"}"
 } elseif { $port_type eq "oracle" } {
     set p6 [lindex $argv ]
     set p7 [lindex $argv ]
     set p8 [lindex $argv ]
     #puts "{'retcode':0,'retinfo':'into-oracle'}"
     #puts "{\"retcode\":\"0\",\"retinfo\":\"in-mysql\"}"
     #puts "port_type=$port_type p1=$p1  p2=$p2  p3=$p3  p4=$p4  p5=$p5  p6=$p6  p7=$p7  p8=$p8"
     spawn ssh $p2@$p1
     expect_after eof { exit  }

     expect "yes/no" { send "yes\r" }
     expect "*assword:" { send "$p3\r" }

     expect "Welcome" { send "sqlplus $p4/$p5@//$p6:$p7/$p8\r" }
     expect "#" { send "sqlplus $p4/$p5@//$p6:$p7/$p8\r" }
     expect "$" { send "sqlplus $p4/$p5@//$p6:$p7/$p8\r" }

     expect "SQL*Plus" {
             puts "{\"retcode\":\"0\",\"retinfo\":\"success\"}"
             exit
             }
     puts "{\"retcode\":\"-2\",\"retinfo\":\"fail\"}"
 }

然后PHP中 ：

$a = system('expect.sh');

然后用xshell客户端执行

 curl -d "{\"interface\":\"test\",\"p1\":\"http\",\"p2\":\"120\",\"p3\":\"127.0.0.52\",\"p4\":\"username\",\"p5\":\"password\",\"tel_ip\":\"127.0.0.53\",\"tel_port\":\"80\"}" "http://www.test.com/test.php"

 

这时候xshell会显示所有expect执行步骤 所以初步尝试修改成了

exec('expect.sh',$a);

 

结果虽然不会直接显示在xshell客户端 但是还是会把所有执行步骤的代码输出到$a里面 而我本来只是想把expect里面的puts “sometext”命令的输出返回给$a 后来问同事 知道了可以修改成

$a = exec('expect.sh');

这样就完美解决问题了！！
