基于学工管理系统的用户登录模块设计与实现——以西宁为例
<form action="/login" method="post"><input type="text" name="username"><input type="password" name="password"><button type="submit">登录</button></form>
from flask import Flask, request, render_template
app = Flask(__name__)
@app.route('/login', methods=['POST'])
def login():
username = request.form['username']
password = request.form['password']
# 查询数据库
conn = mysql.connector.connect(user='root', password='your_password', host='localhost', database='school_management')
cursor = conn.cursor()
query = "SELECT * FROM users WHERE username=%s AND password=%s"
cursor.execute(query, (username, password))
result = cursor.fetchone()
if result:
return "登录成功"
else:
return "用户名或密码错误"
