flask实现获取表单并执行shell

1.一个HTML form input和一个button提供给用户输入

2.使用flask的request获取用户输入的文件名

3.判断输入异常

4.执行shell命令touch aa.txt 并返回ls查看的结果

 

pip install flask

 

filename.py

#!/bin/env python
# _*_coding:utf-8_*_
import os
from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/', methods=['GET'])
def index():
    return '''<form action="/" method="post">
        <label>Filename:</label>
        <input name="filename">
        <input type="submit">
        </form>'''


@app.route('/', methods=['POST'])
def get_sn():
    filename= request.form['filename']
    try:
        filename.encode()
    except Exception,e:
        print Exception,":",e
        return "Please check your input! like this:index.html aa.log"
    os.popen('touch ' + filename).read()
    out=os.popen('ls /var/tmp').read()
    return '<h3> file: <br> %s </h3>' % out


if __name__ == '__main__':
    app.run(host='0.0.0.0',port=5000,debug=True)
