Web Front-endJS TutorialHow to implement login verification jump using Vue+Flask (detailed tutorial)How to implement login verification jump using Vue+Flask (detailed tutorial)
This article mainly introduces the sample code of Vue Flask to implement simple login verification jump. Now I share it with you and give it as a reference.
This article introduces Vue Flask to implement a simple login verification jump and shares it with everyone. The details are as follows:
File location: 
login.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Login</title>
<script type="text/javascript" src="../static/vue.js"></script>
<script type="text/javascript" src="../static/axios.js"></script>
</head>
<body>
<p id="login">
<form action="#" novalidate>
<label for="username">Username</label>
<input type="text" name="username" id="username" placeholder="Enter your Name" v-model="username"><br>
<label for="password">Password</label>
<input type="text" name="password" id="password" placeholder="Enter your Password" v-model="password"><br>
<br>
<button type="button" v-on:click="login">Apply</button>
</form>
</p>
<script type="text/javascript">
var login = new Vue({
el: '#login',
data:{
username: '',
password: ''
},
methods: {
login: function () {
axios.post('http://127.0.0.1:5000/login',{
username: this.username,
password: this.password
}).then(function (response) {
console.log(response.status)
// 其实是应该走后台路由
if(parseInt(response.status) === 200){
window.location.href = 'index'
}
}).catch(function (error) {
console.log(error.response)
})
}
}
})
</script>
</body>
</html>index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Index</title> </head> <body> <h1 id="Hello-This-nbsp-is-nbsp-Index-nbsp-Page">Hello,This is Index Page!</h1> </body> </html>
Login.py
# -*- coding: utf-8 -*-
from flask import Flask, request, session, redirect, url_for, render_template, make_response, jsonify
app = Flask(__name__)
@app.route('/login', methods=('GET', 'POST'))
def login():
if request.method == 'POST':
session['username'] = request.json.get('username')
session['password'] = request.json.get('password')
# 登录成功，则跳转到index页面
return jsonify({'code': 200, 'token': "123456"})
# 登录失败，跳转到当前登录页面
return render_template('login.html')
@app.route('/index')
def index():
# 如果用户名和密码都存在，则跳转到index页面，登录成功
if 'username' in session and 'password' in session:
return render_template('index.html')
# 否则，跳转到login页面
return redirect(url_for('login'))
@app.route('/logout')
def logout():
session.pop('username', None)
session.pop('password', None)
return redirect(url_for('login'))
# set the secret key. keep this really secret:
app.secret_key = 'A0Zr98j/3yX R~XHH!jmN]LWX/,?RT'
if __name__ == '__main__':
app.run(debug=True)The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

The Future of Python and JavaScript: Trends and PredictionsApr 27, 2025 am 12:21 AMThe future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.
Python vs. JavaScript: Development Environments and ToolsApr 26, 2025 am 12:09 AMBoth Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.
Is JavaScript Written in C? Examining the EvidenceApr 25, 2025 am 12:15 AMYes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.
JavaScript's Role: Making the Web Interactive and DynamicApr 24, 2025 am 12:12 AMJavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.
C and JavaScript: The Connection ExplainedApr 23, 2025 am 12:07 AMC and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.
From Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AMJavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.
Python vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AMPython is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.
The Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AMC and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.
