JS-异步功能解析错误

Question

我创建了一个node.js Web应用程序。目前，我在数据库中使用MSSQL。我创建了函数（sql.js）来执行相应的SQL函数。我还创建了一个异步函数处理程序（controllers.js），以便可以在路由器（快速）中使用async和await关键字。路由器使用await关键字调用它们。我调用这些函数没有任何错误，实际上所有内容都返回数据并正常运行，但是在我的文本编辑器（VSCode）中，出现以下错误

[eslint] Parsing error: Unexpected token =>

经过进一步的调查，发现在我的控制台中我收到未处理的promise错误。这让我觉得我对控制器的定义不正确

internal/process/warning.js:18 (node:16328) Warning: a promise was created in a handler at D:\Programs\ColdFusion2016\cfusion\wwwroot\vue_starter\node_modules\express\lib\router\index.js:335:12 but was not returned from it, see http:// goo.gl/ rRqMUw
    at Function.Promise.attempt.Promise.try (D:\Programs\ColdFusion2016\cfusion\wwwroot\vue_starter\node_modules\bluebird\js\release\method.js:29:9)

。有人看到控制器有问题吗？

router.js

const express = require('express');
const router = express.Router();
const {
    asyncGet,
    asyncPost
} = require('../services/controllers')(router);
const sql = require('../services/sql');
const request = require('../services/request');

/// Get Users
asyncGet('/controller/getUsers', async(req, res, next) => {
    console.log('get: /controller/getUsers'); 
    const users = await sql.getUsers(); 
    res.status(200).json(users);   
});
/// Get Products
asyncGet('/controller/getProducts', async(req, res, next) => {
    console.log('get: /controller/getProducts'); 
    const products = await sql.getProducts(); 
    res.status(200).json(products);
});

module.exports = router;

controllers.js

module.exports = (router) => {
    const asyncGet = (route, handler) => {
        return router.get(route, (req, res, next) => {
            handler(req, res, next)
            .catch(error => {
                next(error);
            });
        });
    };
    const asyncPost = (route, handler) => {
        return router.post(route, (req, res, next) => {
            handler(req, res, next)
            .catch(error => {
                next(error);
            });
        });
    };
    return { asyncGet, asyncPost };
};

为了使ESLint支持out <-c("bp", "fm.", "bmi") groups <- c("abc.q", "def.q", "ofj.q") ，在ESLint配置中它支持should be enabled：

async..await
