Question

我有3个文件。 1. server.js - ＆gt;拥有所有包并运行此文件中的所有代码 2. friends.js - ＆gt;是一个模块，它携带一个数组，其中包含来自客户端的所有推送数据 3. apiRoutes.js - ＆gt;是一个路由模块，其任务是执行路由/ api / friends以显示来自friends.js的json对象

当我将friends.js模块和apiRoutes.js模块导入server.js时，它无法识别来自friends.js的friends数组 **

我们如何在路由时访问friends.js中的数据 / api / friends我们运行server.js时的朋友

Server.js：

// server.js
//Incorporate dependencies
var express = require('express');
var bodyParser = require('body-parser');
var path = require('path');

// console.log(htmlRoutes);
//call express
var app = express();
//requiring htmlRoute.js
require('../app/routing/htmlRoutes.js')(app, path);
//requiring apiRoutes.js
require('../app/routing/apiRoutes.js')(app);

// Declare a port
var PORT = 3000;

//data parsing
app.use(bodyParser.urlencoded({extended:false}));
app.use(bodyParser.json());

//requiring the friends.js
require('../app/data/friends.js')


//Listen to port
app.listen(PORT, ()=>{
    console.log('listening to PORT: '+ PORT);
});

friends.js

// friends.js
// array of objects
module.exports = function(app){
var friends =[
    {   
        routeName: "ahmed",
        name:"Ahmed",
        photourl:"https://media.licdn.com/mpr/mpr/shrinknp_400_400/p/6/005/064/1bd/3435aa3.jpg",
        questions:[
                    5,
                    1,
                    4,
                    4,
                    5,
                    1,
                    2,
                    5,
                    4,
                    1
        ]
    }   
]

//retreiving stored objects with person's data
app.post("/survey", function(req, res){
    var incomingPerson = req.body;
    incomingPerson.routeName = incomingPerson.name.replace(/\s+/g, "").toLowerCase();
    console.log(incomingPerson);
    // friends.push(person);
})


}

apiRoutes.js

// apiRoutes.js
//PARAMETERIZATION
module.exports = function(app){
//A GET route with the url `/api/friends`. This will be used to display a JSON of all possible friends.
app.get("/api/friends/:whoDoIWantToSee?", function(req, res){
    var chosen = req.params.whoDoIWantToSee;
    res.json(friends);
    // if(chosen){
    //     res.json(friends.chosen);
    // }

    // console.log(chosen);
});
//A POST routes `/api/friends`. This will be used to handle incoming survey results. This route will also be used to handle the compatibility logic. 
}

您可以从friends.js模块中导出// array of objects const friends = [ { routeName: "ahmed", name:"Ahmed", photourl:"https://media.licdn.com/mpr/mpr/shrinknp_400_400/p/6/005/064/1bd/3435aa3.jpg", questions:[ 5, 1, 4, 4, 5, 1, 2, 5, 4, 1 ] } ]; module.exports = function(app){ //retreiving stored objects with person's data app.post("/survey", function(req, res){ var incomingPerson = req.body; incomingPerson.routeName = incomingPerson.name.replace(/\s+/g, "").toLowerCase(); console.log(incomingPerson); // friends.push(person); }); return friends; }; module.exports.friends = friends;数组，如下所示：

friends

然后，在您想要访问单身const friends = require('./friends.js').friends;数组的任何地方，您都可以这样做：

month = newVal;
