使用猫鼬时无法获得

Question

我的router.js

​

const express = require("express")
const Note = require("../models/nodeModel")
const router = express.Router()

router.route("/notes").get((req, res) => {
    Note.find({ show_day: "2020-9-10" })
        .then(foundNotes => res.json(foundNotes))
})

module.exports = router

​

我的server.js

​

const express = require("express")
const app = express()
const cors = require("cors")
const mongoose = require("mongoose");

app.use(cors())
app.use(express.json())

mongoose.connect("mongodb://localhost:27017/my-app")

app.use("/",require("./routes/noteRouter"))

app.listen(3000,function(){
    console.log("server is running on port 3000");
})

​

我的nodeModel.js

​

const mongoose = require('mongoose')

const noteSchema = {
    show_day:String,
    diary_day: String,
    content: String
}

const Note = mongoose.model("diary",noteSchema)

module.exports = Note;

​

当我尝试console.log Note.find()时，它可以工作。但是当我运行server.js时，浏览器说它不能/为什么不能工作？

Answer 1

您只有/notes端点，没有/路由。

您应该在router.js中像这样改变路线：

const express = require("express")
const Note = require("../models/nodeModel")
const router = express.Router()

router.route("/").get((req, res) => {
    Note.find({ show_day: "2020-9-10" })
        .then(foundNotes => res.json(foundNotes))
})

module.exports = router

或者访问/notes而不是/。
