gqylpy-ssh

本源代码使用了 paramiko 库,这个库是基于 LGPL 协议发布的。

在远程服务器执行命令并得到命令结果,它是对 paramiko 库的二次封装。通过 Command 对象,你可以得到这条命令的执行结果,状态等信息。

pip3 install gqylpy_ssh

首先初始化 GqylpySSH 实例:

import gqylpy_ssh as gssh

gssh.__init__(
    hostname='192.168.1.7',
    username='gqylpy',
    password=...
)

通过 cmd 函数在远程服务器执行命令,它返回一个 Command 对象:

c = gssh.cmd('hostname')

若命令执行失败,调用此方法将抛出异常:

c.raise_if_error()

获得命令状态或输出:

status: bool = c.status
output: str = c.output
status, output = c.status_output

获得命令输出,若命令执行错误,将抛出异常

output: str = c.output_else_raise

获得命令输出,若命令执行错误,将返回 "define value":

output: str = c.output_else_define('define value')

检查命令输出是否包含某个字符串,得到一个布尔值:

x: bool = c.contain_string('string')

获得命令输出,如果输出包含某个字符串,否则抛出异常:

output: str = c.output_if_contain_string_else_raise('string')

这个方法可将带有标题的输出转为字典:

it = c.output2dict('kubectl get nodes')

如果你需要创建多个 GqylpySSH 实例:

from gqylpy_ssh import GqylpySSH, Command

ssh = GqylpySSH('192.168.1.7', **params)
c: Command = ssh.cmd('hostname')
output: str = c.output_else_raise
import gqylpy_ssh as gssh

gssh.__init__('192.168.1.7', **params, gname='1.7')
gssh.__init__('192.168.1.9', **params, gname='1.9')

output: str = gssh.cmd('hostname', gname='1.7').output_else_raise
output: str = gssh.cmd('hostname', gname='1.9').output_else_raise

gssh.cmd('hostname').output == gssh.cmd('hostname', gname='1.7').output
