We will use waitress as WSGI to serve the Flask web application, to start it with:
waitress-serve –port=8080 main:app
(in our case, we have main.py with app = Flask(name) inside)
Or you can edit main.py, so it can run with waitress directly, only need two changes:
1. add from waitress import serve at beginning
2. update the last line to serve(app, host=’0.0.0.0′, port=8080)
Here is main.py:
from flask import Flask, redirect, render_template, request, session, url_for
import subprocess
app = Flask(__name__)
def api(cmd):
p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE,
stderr=subprocess.PIPE, universal_newlines=True)
stdout, stderr = p.communicate()
return stdout
@app.route("/", methods = ["POST", "GET"])
def login():
if request.method == "POST":
user = request.form["name"]
return redirect(url_for("success", name=user))
else:
return render_template("login.html")
@app.route("/success", methods = ["POST", "GET"])
def success():
ip_addr = request.form.get('ip_addr')
cmd = request.form.get('name')
print(cmd)
full_cmd = "/home/zhuby/sshpass -p my_password ssh " + ip_addr + " -o ConnectTimeout=2 -o StrictHostKeyChecking=no -o LogLevel=Error " + cmd
print(full_cmd)
return render_template("success.html", subprocess_output=api(full_cmd))
