Question

我写了一个小脚本，试图从html页面获取远程主机的主机名。该脚本可在cli上成功运行，但在浏览器上运行时似乎无法连接到远程主机并获取信息。有人可以告诉我我想念什么吗？

#!/usr/bin/env python

import paramiko
import cgi

def ssh_connect(host,cmd):
    try:
        ssh_client =paramiko.SSHClient()
        ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh_client.connect(hostname=host, timeout=10)
        stdin,stdout,stderr=ssh_client.exec_command(cmd)
        output=(stdout.readlines())
        return output
        ssh_client.close()
    except KeyboardInterrupt:
        output="KeyboardInterrupt"
        sys.exit(0)
    except paramiko.AuthenticationException:
        return "authenication failed"

remote_hostname=ssh_connect('10.1.2.2','hostname' )


print "Content-type:text/html\r\n\r\n"
print '<html>'
print '<head>'
print '<title>Test</title>'
print '</head>'
print '<body>'
print '<h2>the hostname on remote host is %s</h2>' %(host,remote_hostname)
print '</body>'
print '</html>'
