Question

我尝试将控制器添加到我的项目中，但无法调整我的异步/等待语法。

我的NodeJs / Express项目具有以下结构：

controllers/
  categories.js
models/
  category.js
routes/
  categoryRoutes.js
services/
  db.js
app.js
package.json

categoryRoutes.js 路线：

const express = require('express');
const router = express.Router();

// Controlller
const CategoryController = require('../controllers/categories');

router.post('/get-all', CategoryController.getAll); // This is where the app fails

categories.js 控制器：

// Model
const Category = require('../models/category');

exports.getAllCategories = async (req, res, next) => {
    const result = await Category.getAll();
    next();
}

category.js 模型：

var db = require('../services/db');

exports.getAll = async () => {
    const categories = await db.get().query('SELECT * FROM categories');
    next(null, categories);
}

代码在categoryRoutes.js文件中产生以下错误：

 **\node_modules\express\lib\router\route.js:202

在Router.get / post中使用 Async / Await 控制器/模型函数的正确方法是什么？？

在快速路由中使用async / await控制器功能时出错
