Django Ajax 实现Web命令行执行
Ajax序列化实现简单命令工具: 我们通过定制Django,配合命令行执行功能可以实现远程命令执行页面.

Ajax实现非交互Shell: 虽然Ajax是非交互的,但利用循环交互同样可以实现远程命令执行功能.
首先是前端index.html代码中我们使用了xterm这个前端命令行库,该库可实现一个WebShell环境.
<link rel="stylesheet" href="https://cdn.lyshark.com/xterm/xterm.css" />
<script src="https://cdn.lyshark.com/xterm/xterm.js"></script>
<script src="https://cdn.lyshark.com/jquery/3.5.1/jquery.min.js"></script>
<div id="terminal"></div>
<script type="text/javascript">
var window_width = $(window).width()-200;
var window_height = $(window).height()-300;
var term = new Terminal(
{
cols: Math.floor(window_width/9),
rows: Math.floor(window_height/20),
useStyle:false,
convertEol: true,
cursorBlink:true,
cursorStyle:null,
rendererType: "canvas",
}
);
term.open(document.getElementById('terminal'));
term.writeln("welcome to lyshark web terminal!");
term.write("[shell] # ");
let input = '';
term.on('key', (key, ev) => {
let code = key.charCodeAt(0);
console.log(code);
// 如果按下回车,则发送命令,并等待输出结果
if(code == 13)
{
term.write("\r\n");
$.ajax({
url:"/_ajax/",
type:"POST",
contentType:"application/json;",
data: JSON.stringify({"command":input}),
success:function (res) {
term.write(res);
}
});
input ='';
}
else
{
input += key
term.write(key);
}
});
</script>
而对应的后台文件views.py视图中只需要接受参数并判断执行即可.
from django.shortcuts import render,HttpResponse
import paramiko,json
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
def ssh_shell(address,username,password,port,command):
ssh.connect(address,port=port,username=username,password=password)
stdin, stdout, stderr = ssh.exec_command(command)
result = stdout.read()
if not result:
result=stderr.read()
ssh.close()
return result.decode()
def ajax(request):
if request.method == "POST":
data = request.body.decode("utf-8")
json_data = json.loads(data)
command = json_data.get("command")
if len(data) == 0:
return HttpResponse("[shell] # ")
else:
ref = ssh_shell("192.168.1.112","root","1233","22",command)
return HttpResponse(ref + "\n[shell] # ")
return render(request, "index.html")
