当用户注册后，我如何在我的flask web应用程序中登录该用户？

from flask import Flask, render_template, request, session, redirect

app = Flask(__name__)
app.secret_key = 'your_secret_key'  # 设置会话密钥

# 用户表，用于存储用户的登录信息
users = {
    'user1': {
        'password': 'password1',
        'name': 'User One'
    },
    'user2': {
        'password': 'password2',
        'name': 'User Two'
    }
}

# 注册页面
@app.route('/register', methods=['GET', 'POST'])
def register():
    if request.method == 'POST':
        username = request.form['username']
        password = request.form['password']
        users[username] = {'password': password, 'name': ''}
        return redirect('/login')
    return render_template('register.html')

# 登录页面
@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'POST':
        username = request.form['username']
        password = request.form['password']
        if username in users and users[username]['password'] == password:
            session['username'] = username  # 将登录状态保存到会话中
            return redirect('/profile')
        else:
            return 'Invalid username or password'
    return render_template('login.html')

# 登录后的操作
@app.route('/profile')
def profile():
    if 'username' in session:
        username = session['username']
        user = users[username]
        return f'Welcome, {user["name"]}!'
    return redirect('/login')

# 退出登录
@app.route('/logout')
def logout():
    session.pop('username', None)
    return redirect('/login')

if __name__ == '__main__':
    app.run()
