from flask import Flask, request, session

app = Flask(__name__)
app.secret_key = 'secret_key'

@app.route('/login', methods=['POST'])
def login():
    username = request.form['username']
    password = request.form['password']
    # 验证用户名和密码
    session['username'] = username
    return '登录成功！'

@app.route('/profile')
def profile():
    if 'username' in session:
        return f'欢迎回来，{session["username"]}！'
    else:
        return '请先登录'
