async/await nodejs 未定义

Question

我的代码 return 对象正确，但是当我尝试从中获取值时，它 return 未定义。确切的问题是什么？

const Notification = require('../../../models/Notification');

    module.exports = function onRouterload() {
                return {
                    allRouter: async (req, res, next) => {
                        // for the admin layout
                        req.app.locals.layout = 'admin';
                        // load notification
                        async function notification() {
                            try {
                                const result = Notification.findAll({ where: { status: 'unread' } });
                                const data = await result;
                                return data;
                            } catch (error) {
                                console.log(error);
                            }
                        }
                        const notificationInfo = await notification();
                       // return undefined               
                       console.log(notificationInfo.status);
                        res.locals.notification = notificationInfo;
                        next();
                    },
                };
            };

findAll returns 一个项目数组，因此 notificationInfo 包含一个数组，您应该遍历它以便能够访问 status 每一项的字段：

const notificationInfo = await notification();
for (const item of notificationInfo) {
  console.log(item.status);
}
