python实现Flask POST Demo

数据处理逻辑


from flask import Flask, request
 
app = Flask(__name__)
 
 
@app.route('/', methods=['POST'])
def index():
    username = request.form['username']
    password = request.form['password']
    if username == "Jhon" and password == "1":
        return f"Welcome {username}"
    else:
        return f"Welcome!"
 
 
if __name__ == '__main__':
    app.run(debug=True)

前端代码


html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>GET and POSTtitle>
head>
<body>
    <form action = "http://localhost:5000" method = "post">
         <table>
            <tr>
                <td>Nametd>
                <td><input type ="text" name ="username">td>
            tr>
            <tr>
                <td>Passwordtd>
                <td><input type ="password" name ="password">td>
            tr>
            <tr>
                <td><input type = "submit">td>
            tr>
        table>
