你可以使用最簡單的python web框架Flask來實現登入驗證。

建立app.py：

from flask import Flask

from flask import Flask, flash, redirect, render_template, request, session, abort

import os

app = Flask(__name__)

@app.route("/")

def home():

if not session.get("logged_in"):

return render_template("login.html")

else:

return "Hello Boss!"

@app.route("/login", methods=["POST"])

def do_admin_login():

if request.form["password"] == "password" and request.form["username"] == "admin":

session["logged_in"] = True

else:

flash("wrong password!")

return home()

if __name__ == "__main__":

app.secret_key = os.urandom(12)

app.run(debug=True,host="0.0.0.0", port=4000)

建立模板檔案./templates/login.html，主要程式碼如下：

<form action="/login" method="POST">

<input type="username" name="username" placeholder="Username">

<input type="password" name="password" placeholder="Password">

<input type="submit" value="Log in">

</form>

執行：

python app.py
