Question

我是js的新手，所以对我很轻松。我的主要目标是从Message.js（一个名为messages的数组）中获取参数，并在服务器中使用它们。对于这部分只是在屏幕上打印它们会做。

给帮助者tnx！：）

我的Message.js文件如下所示：

$(document).ready(function() {
       var messages = [
    {
        name: 'I am Message number one',   //a js field in an object(message in this case) and it's value after the semicolon
        texts: [                               //an array of 3 strings in js
            'mary had a little lamb',
            'hail hydra',
            'spider-man rocks'
        ],
        images: [                               //an array of 2 images in js
            'https://fb-s-c-a.akamaihd.net/h-ak-xat1/v/t1.0-9/10156120_630371003705480_8529510393733631385_n.png?oh=8412d9c3b69d39b6030d66f9709e1e1e&oe=58EEA4F2&__gda__=1492580526_84a87f898177ec43770cf3a5317fdb31',
            'https://fb-s-a-a.akamaihd.net/h-ak-xtf1/v/t1.0-9/10268685_630867936989120_785222708436272994_n.jpg?oh=c15c538b5385843ad0b44affda0f378c&oe=58B9EB5F&__gda__=1488430186_6c7c227a21e77492f092dc999834157d'
        ],
        times: [                       //array of vars initialized in Dates kind values
            {
                fromDate: new Date(2016, 0, 1),  //jan is 0, feb is 1, and so on...
                toDate: new Date(2016, 11, 31),
                fromTime: '09:00',
                toTime: '22:53',
                days: [0, 1, 5]    // sunday starts with a 0 then monday is 1 and so on...
            }
        ]
    }, //until here this is a one object of 'message'
    {
        name: 'I am Message number two',   //a js field in an object(message in this case) and it's value after the semicolon
        texts: [
            'soon in theaters',        //an array of 4 strings in js
            'the lion king is Simba',
            'tiom&pumba rules',
            'spider-man is awesome!'
        ]
         }];
         }

我不知道该怎么做服务器的部分 尝试过这样的事情：

    var http = require('http');
    var port = 8080;
    var fs = require("fs");



    const querystring = require("querystring");
    function onRequest(request, response){
       console.log("user made a request " + request.url);
       response.writeHead(200);
       response.write(messages[0].name);
       response.write("here is your data");
       response.toString(message[0]);
       response.end();

}

http.createServer(onRequest).listen(port);

Answer 1

在Message.js更改：

var messages = [ ...

为：

module.exports = [ ...

并使用它：

var messages = require('./Message.js');

在您应用的其他一些文件中。

如果该文件不在同一目录中，则可能需要使用：

var messages = require('../Message.js');

或：

var messages = require('../lib/Message.js');

或类似的内容，具体取决于您希望require所在文件的角度所在的位置。

Answer 2

在你的Message.js中添加

exports.messages= messages; //add this after your messages array declaration

和你的服务器......

var myMessages= require('./Message.js');

var messages= myMessages.messages;

如何在node.js服务器中获取和使用.js中的变量和参数？
