====== Ejecutar solo un comando ======
app.py
<code>
from flask import Flask
from flask import request
import subprocess

app = Flask('flaskshell')

@app.route('/create')
def get_status():
        command_ls = "touch fichero_touch"

        try:
            result_ls = subprocess.check_output(
                [command_ls], shell=True)
        except Exception as e:
            print (e)
            return 'Fail'

        return 'Success'

if __name__ == '__main__':
    app.run()
</code>

levantamos el servidor:
  python app.py

Si lanzamos este comando, ejecuta el comando, en este caso **fichero_touch**
  curl http://127.0.0.1:5000/create

====== Coger variables de POST ======
app_post.py
<code>
from flask import Flask
from flask import request
import subprocess

app = Flask('flaskshell')

@app.route('/usuario' , methods = ['POST'])
def get_variables():
        fichero=request.form.get('fichero')

        command = "touch " + fichero

        try:
            result_ls = subprocess.check_output(
                [command], shell=True)
        except Exception as e:
            print (e)
            return result_ls

        return 'Success'

if __name__ == '__main__':
    app.run()
</code>
Levantamos el servidor:
  python3 app_post.py
Si ejecutamos este comando, nos crea el fichero que le pasemos en la variable fichero, en este caso fichero_prueba.txt
  curl -X POST http://127.0.0.1:5000/usuario -d "fichero=fichero_prueba.txt"

====== Coger variables de POST multiple ======
app_post.py
<code>
from flask import Flask
from flask import request
import subprocess

app = Flask('flaskshell')

@app.route('/usuario' , methods = ['POST'])
def get_variables():
        user=request.form.get('user')
        password=request.form.get('password')

        command = 'radtest ' + user + ' ' + password + ' ' + '10.103.0.6 0 testing123-1'
        print (command)

        try:
            result_ls = subprocess.check_output(
                [command], shell=True)
        except Exception as e:
            print (e)
            return result_ls

        return 'Success'

if __name__ == '__main__':
    app.run()
</code>
Levantamos el servidor:
  python3 app_post.py
Si ejecutamos este comando  hace un login contra servidor radius con user bob y password hello:
  curl -X POST http://127.0.0.1:5000/usuario -d "user=bob&password=hello"
  
====== Configuración ======
Escuchar en todas las ips:
    app.run(host= '0.0.0.0')
