本文介紹了Vue+Flask實現簡單的登錄驗證跳轉,分享給大家,具體如下:
文件位置:
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> <div 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> </div> <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) // 其實是應該走后臺路由 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> <h2>Hello,This is Index Page!</h2> </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') # 登錄成功,則跳轉到index頁面 return jsonify({'code': 200, 'token': "123456"}) # 登錄失敗,跳轉到當前登錄頁面 return render_template('login.html') @app.route('/index') def index(): # 如果用戶名和密碼都存在,則跳轉到index頁面,登錄成功 if 'username' in session and 'password' in session: return render_template('index.html') # 否則,跳轉到login頁面 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)
