Python编程中常用的Controller方法

在Python编程中，Controller方法用于处理用户输入、调用Model和View，并对用户输入做出响应。下面是一些常用的Controller方法和相应的使用示例。

1. index()方法：显示网站的首页。

def index():
    return render_template('index.html')

2. login()方法：处理用户登录请求。

def login():
    if request.method == 'POST':
        username = request.form['username']
        password = request.form['password']

        if username == 'admin' and password == '123456':
            return render_template('dashboard.html')
        else:
            return render_template('login.html', error='Invalid username or password')
    else:
        return render_template('login.html')

3. register()方法：处理用户注册请求。

def register():
    if request.method == 'POST':
        username = request.form['username']
        password = request.form['password']

        # Save user to database or perform other necessary actions
        return render_template('thank_you.html', username=username)
    else:
        return render_template('register.html')

4. logout()方法：处理用户登出请求。

def logout():
    # Clear user session or perform other necessary actions
    return redirect(url_for('index'))

5. user_profile()方法：显示用户个人资料。

def user_profile(username):
    # Fetch user profile from database or perform other necessary actions
    return render_template('profile.html', username=username)

6. create_post()方法：处理用户创建新帖子请求。

def create_post():
    if request.method == 'POST':
        title = request.form['title']
        content = request.form['content']

        # Save post to database or perform other necessary actions
        return redirect(url_for('index'))
    else:
        return render_template('create_post.html')

7. edit_post()方法：处理用户编辑已有帖子请求。

def edit_post(post_id):
    if request.method == 'POST':
        title = request.form['title']
        content = request.form['content']

        # Update post in database or perform other necessary actions
        return redirect(url_for('index'))
    else:
        # Fetch post from database based on post_id
        return render_template('edit_post.html', post=post)

8. delete_post()方法：处理用户删除已有帖子请求。

def delete_post(post_id):
    # Delete post from database or perform other necessary actions
    return redirect(url_for('index'))

9. add_to_cart()方法：处理用户将商品添加到购物车的请求。

def add_to_cart(product_id):
    # Add product to user's shopping cart in database or perform other necessary actions
    return redirect(url_for('cart'))

10. checkout()方法：处理用户结账的请求。

def checkout():
    if request.method == 'POST':
        shipping_address = request.form['shipping_address']
        billing_address = request.form['billing_address']
        payment_method = request.form['payment_method']

        # Process payment and update order status in database or perform other necessary actions
        return render_template('order_complete.html')
    else:
        return render_template('checkout.html')

这些是常用的一些Controller方法及其使用示例。根据实际需求，可以调整这些方法的逻辑以及参数。
