Question

我正在尝试将 postgresql 数据库连接到我的后端和应用程序。获取数据库中的信息。我从 index.js 运行服务器并使用 shoesCtrl 作为检索信息的控制器。每次我在 Postman 上测试我的端点时，我都会得到： “类型错误：dbInstance.read_shoes 不是 readShoes 的函数”

index.js

const express = require('express')
const app = express()
const shoesCtrl = require('./controllers/shoesCtrl')

const massive = require('massive')
const{SERVER_PORT, CONNECTION_STRING} = process.env

app.use(express.json())

massive({
    connectionString: CONNECTION_STRING,
    ssl: {
        rejectUnauthorized: false
    }
})
.then(dbInstance => {
    app.set('db', dbInstance)
    app.listen(SERVER_PORT, () => console.log(`Server is bumping on ${SERVER_PORT}`))
})
.catch(err => console.log(err))

app.get("/shoes", shoesCtrl.readShoes)
app.get("/shoes/:brand", shoesCtrl.readBrand)

shoesCtrl.js

module.exports = {

readShoes: (req, res) =>{
    const dbInstance = req.app.get('db')

    dbInstance.read_shoes()
    .then(shoes => res.status(200).send(shoes))
    .catch(err => {
        res.sendStatus(500).send(console.log(err))
    })
},

readBrand: (req, res) => {
    const dbInstance = req.app.get('db')
    const {brand} = req.params

    dbInstance.read_product(brand)
    .then(shoe => res.status(200).send(shoe))
    .catch(err => {
        res.sendStatus(500).send({errorMessage: "Oops! Something went wrong. Our engineers have been informed!"})
        console.log(err)
    })
}

我的 read_shoes.sql

select * from shoes;

测试我的端点时不断收到错误消息
