这是模型Hotel.js文件
import mongoose from "mongoose";
const {Schema} = mongoose
const HotelSchema = new mongoose.Schema({
name:{
type:String,
required:true
},
type:{
type:String,
required:true
},
city:{
type:String,
required:true
},
address:{
type:String,
required:true
},
distance:{
type:String,
required:true
},
photos:{
type:[String],
},
title:{
type:String,
required:true
},
desc:{
type: String,
required:true
},
rating:{
type: Number,
min:0,
max:5
},
rooms:{
type:[String]
},
// for showing cheapest hotels
cheapestPrice:{
type:Number,
required:true
},
// for showing featured hotels
featured:{
type:Boolean,
deafult:false,
}
})
export default mongoose.model("Hotel",HotelSchema)
这是hotel.js的路由
import express from "express"
import Hotel from "../models/Hotel.js";
const router = express.Router();
router.post("/", async (req,res)=>{
const newHotel = new Hotel(req.body);
try{
const savedHotel = await newHotel.save()
res.status(200).json(savedHotel)
}catch(err){
res.status(500).json(err)
}
})
export default router
这是主index.js文件
import express from "express"
import dotenv from "dotenv"
import mongoose from "mongoose"
import hotelRoute from './routes/hotels.js'
const app = express()
dotenv.config()
const connect = async () =>{
try{
await mongoose.connect(process.env.MONGO)
console.log("Connected to mongodb")
}catch(err){
throw err;
}
}
mongoose.connection.on("connected",()=>{
console.log("mongodb connected")
})
mongoose.connection.on("disconnected",()=>{
console.log("mongodb disconnected")
})
//Middleware
app.use(express.urlencoded({extended:true}))
app.use(express.json())
app.use("/api/hotel",hotelRoute)
app.listen(8000,() =>{
connect()
console.log("Connected to backend")
})
}
在控制台我得到
Connected to backend
mongodb connected
Connected to mongodb
首先你必须检查你的请求。身体数据。您可以验证您的请求。Body with joi validator
和(或)expression - join -validation.
在mongoose中，你必须从你的模式生成一个模型:
const Kitten = mongoose.model('Kitten', kittySchema);
post方法URL = http://localhost:8800/api/hotels
尝试使用http://
当您通过Postman使用POST方法时。同样的问题也发生在我身上。我缺少的是JSON的数据类型。
您可能将请求作为数据类型文本发送。
在相同的项目中得到了相同的错误，但我通过执行
获得了200状态的结果res.status(200).json(hotels);
在hotels.js文件中的所有GET,PUT,POST,DELETE方法中代替
req.send(200) *or* req.send(500)
希望这是有用的!!谢谢!
