使用 Python Paramiko 通过 SSH 将输入/变量传递给命令/脚本 [英] Pass input/variables to command/script over SSH using Python Paramiko
问题描述
我在通过 SSH 将响应传递给远程服务器上的 bash 脚本时遇到问题.
I am having issues passing responses to a bash script on a remote server over SSH.
我正在用 Python 3.6.5 编写一个程序,它将通过 SSH 连接到远程 Linux 服务器.在这个远程 Linux 服务器上,我正在运行一个 bash 脚本,它需要用户输入才能填写.无论出于何种原因,我都无法通过 SSH 从我的原始 python 程序传递用户输入,并让它填写 bash 脚本用户输入问题.
I am writing a program in Python 3.6.5 that will SSH to a remote Linux server. On this remote Linux server there is a bash script that I am running which requires user input to fill in. For whatever reason I cannot pass a user input from my original python program over SSH and have it fill in the bash script user input questions.
main.py
from tkinter import *
import SSH
hostname = 'xxx'
username = 'xxx'
password = 'xxx'
class Connect:
def module(self):
name = input()
connection = SSH.SSH(hostname, username, password)
connection.sendCommand(
'cd xx/{}/xxxxx/ && source .cshrc && ./xxx/xxxx/xxxx/xxxxx'.format(path))
SSH.py
from paramiko import client
class SSH:
client = None
def __init__(self, address, username, password):
print("Login info sent.")
print("Connecting to server.")
self.client = client.SSHClient() # Create a new SSH client
self.client.set_missing_host_key_policy(client.AutoAddPolicy())
self.client.connect(
address, username=username, password=password, look_for_keys=False) # connect
def sendCommand(self, command):
print("Sending your command")
# Check if connection is made previously
if (self.client):
stdin, stdout, stderr = self.client.exec_command(command)
while not stdout.channel.exit_status_ready():
# Print stdout data when available
if stdout.channel.recv_ready():
# Retrieve the first 1024 bytes
alldata = stdout.channel.recv(1024)
while stdout.channel.recv_ready():
# Retrieve the next 1024 bytes
alldata += stdout.channel.recv(1024)
# Print as string with utf8 encoding
print(str(alldata, "utf8"))
else:
print("Connection not opened.")
Connect
类中的最后一个 /xxxxxx
是启动的远程脚本.它将打开一个等待格式的文本响应,例如
The final /xxxxxx
in class Connect
is the remote script that is launched.
It will open a text response awaiting a format such as
你叫什么名字:
而且我似乎无法找到一种方法将响应从我的 main.py
文件中的 Connect
类正确传递给脚本.
and I cannot seem to find a way to properly pass the response to the script from my main.py
file within the class Connect
.
我尝试将 name
作为参数或变量传递的每一种方式,答案似乎都消失了(可能是因为它试图在 Linux 提示符下而不是在 bash 脚本中打印它)
Every way I have tried to pass name
as an argument or a variable the answer seems to just disappear (likely since it is trying to print it at the Linux prompt and not within the bash script)
我认为使用 read_until
函数查找问题末尾的 :
可能有效.
I think using the read_until
function to look for the :
at the end of the question may work.
建议?
推荐答案
将您的命令所需的输入写入stdin
:
Write the input that your command needs to the stdin
:
stdin, stdout, stderr = self.client.exec_command(command)
stdin.write(name + '
')
stdin.flush()
<小时>
(您当然需要将 name
变量从 module
传播到 sendCommand
,但我假设您知道如何做那部分).
(You will of course need to propagate the name
variable from module
to sendCommand
, but I assume you know how to do that part).
