javascript 使用MongoDB，mLab和Mongoose设置数据库

Posted 2021-05-03

const express = require("express");
const app = express();
const request = require("request");
const bodyParser = require('body-parser');
const mongoose = require("mongoose");

//Connecting to the mongodb database(we use mlab)
mongoose.connect("mongodb://kody:[e-mail]:45752/gaming_website_database", {
    useNewUrlParser: true
});

//Our template for our data when we store it
var gameSchema = new mongoose.Schema({
    title: String,
    creator: String,
    width: Number,
    height: Number,
    fileName: String,
    thumbnailFile: String
});

//Making that template into a model we can use to add, delete, and find out data. This model will be made into the Games collection when we start adding data.
var Game = mongoose.model("Game", gameSchema);

//Creating a new piece of data. (a new game object)
// var testgame = new Game({
//     title: "Booty Master",
//     creator: "Jesus",
//     width: 480,
//     height: 680,
//     fileName: "Yeet.swf",
//     thumbnailFile: "imapicture.jpg"
// });

// //Adding that data to our database
// testgame.save(function(error, data){
//     if(error){
//         console.log("There was an error saving the data");
//     }else{
//         console.log("Data saved to datbase. Here is the data that was saved: ");
//         console.log(data);
//     }
// });

//Easier way to add to the database
Game.create({
    title: "Booty Master",
    creator: "Jesus",
    width: 480,
    height: 680,
    fileName: "Yeet.swf",
    thumbnailFile: "imapicture.jpg"
}, function(error, data){
    if(error){
        console.log("Problem adding data to collection");
    }else{
        console.log("Data added: ");
        console.log(data);
    }
});

//Listing all of the Games in the collection
Game.find({}, function(error, data){
    if(error){
        console.log("Problem finding data");
    }else{
        console.log("Here is all of the data in the Games collection: ");
        console.log(data);
    }
})

//Our ghetto database
const gamesData = [
