會(huì)員登錄裝飾器

在home.views.py中創(chuàng)建登錄裝飾器

from functools import wraps

# 要求登錄才能訪問(wèn)
def user_login_require(func):
    @wraps(func)
    def decorated_function(*args, **kwargs):
        if session.get('login_user', None) is None:
            # 如果session中未找到該鍵，則用戶需要登錄
            return redirect(url_for('home.login', next=request.url))
        return func(*args, **kwargs)

    return decorated_function

增加登錄裝飾器

@home.route('/user/')
@user_login_require
def user():
    return render_template('home/user.html')

也需要將以下功能添加要求登錄离咐。
