连接mongodb：
const mongoose = require("mongoose")
mongoose.connect('mongodb://127.0.0.1:27017/zg5_zk3_2204_express',(err)=>{
if(!err){
console.log('连接成功!');
}
})
module.exports=mongoose
创建表模型：
const mongoose = require("./db")
var Schema = mongoose.Schema
// 图书
var bookSchema = new Schema({
bookName:String,
img:String,
// 判断是否在书架里: false没在书架,true在书架
state:{
type:Boolean,
default:false
},
// 判断是否看完：false正在看，true已完结
bookState:{
type:Boolean,
default:false
}
})
var bookModel = mongoose.model("Book",bookSchema)
// 用户
var userSchema = new Schema({
mobile:String,
passWord:String
})
var userModel = mongoose.model("User",userSchema)
module.exports = { bookModel,userModel }
后端接口：
// 登录时添加用户
router.post("/user/add",async (req,res)=>{
var data = req.body
await userModel.create(data)
res.send({
token:data.mobile
})
})
// shop路由及book路由图书展示
router.get("/book/list",async (req,res)=>{
var data
if(!req.query.search){
data = await bookModel.find()
}else{
data = await bookModel.find({bookName:req.query.search})
}
res.send({
data
})
})
// shop路由的图书添加
router.post("/book/add",async (req,res)=>{
let data = req.body._id
await bookModel.updateOne({_id:data},{state:true})
res.send({})
})
// bookState状态的更改
router.post("/bookState/update",async (req,res)=>{
let data = req.body
await bookModel.updateOne({_id:data._id},{bookState:data.bookState})
res.send({})
})
// state状态的更改
router.post("/state/update",async (req,res)=>{
let data = req.body
await bookModel.updateOne({_id:data._id},{state:false})
res.send({})
