我在number_format中有以下代码。
app.js我创建了mongodb数据库var express = require("express");
var app = express();
var port = 3001;
app.get("/", (req, res) => {
res.send("success");
});
app.listen(port, () => {
console.log("Server listening on port " + port);
});
var mongoose = require('mongoose');
mongoose.createConnection('mongodb://localhost:27017/mydb');
var Schema = mongoose.Schema;
var productSchema=new Schema({
created_at: String,
id: Number
});
const Products = mongoose.model("myc",productSchema);
app.get('/',function(req,res){
Products.find({},function(err,products){
res.json(products)
});
})
// module.exports = app;
和mydb作为内容文档的集合。
当我输入localhost：3000时，我没有看到存储在Mongodb中的JSON数据只显示空白页面。请帮忙
