Question

因此，我有一个名为 server 的应用，另一个是 client 的应用，服务器为服务器提供了供客户端使用的所有数据。问题是，当我尝试从服务器（端口8080）发出并且接收到客户端（端口80）时，什么都没有发生

服务器：app.js

var app = require ("./config/server.js");

var http = require('http').createServer(app);
var io = require("socket.io")(http);

http.listen(8080, function(){
    console.log('Server side instagram_clone_v01 online');
});

io.sockets.on('connect', function (socket) {
    console.log("conectou socket.id="+socket.id);
});

当服务器数据库插入新照片时，这称为：

io.emit("newPhoto");

客户端：app.js

var app = require('./config/server');

app.listen(80, function(){
    console.log('Server client instagram_clone_v01 online');
});

var io = require('socket.io');

这在 ejs代码中被称为：

const socket = io.connect('http://localhost:8080', {transports: ['websocket', 'polling', 'flashsocket']});
socket.on('newPhoto',function(){
     load_posts();
});

编辑，答案为 Federico

我向服务器添加了io.origins('*:*');，但不发光

我不知道您为什么使用io.sockets.on，在文档中找不到它。我已经尝试清除代码，尝试一下。

server.js

var app    = require ("./config/server.js");    
var http   = require('http').Server(app);
var io     = require("socket.io")(http);

http.listen(8080, function(){
    console.log('Server side instagram_clone_v01 online');
});

io.on('connect', socket => {

    console.log("user" + socket.request.user.id + "connected");

    socket.on('disconnect', function() {

        console.log('A user has disconnected');

    }

    io.emit("newPhoto");
});

client.js

    //io() works only when connecting to a socket hosted on the same url/server
    // For connecting to an external socket hosted elsewhere, you would use io.connect('URL');
    var socket = io();    
    socket.on('newPhoto',function(){
             load_posts();
        });

在登录后将用户重定向到的页面中，应包括以下脚本：

<script src="/socket.io/socket.io.js"></script>
<script src="/client.js"></script>

socket.io不发光
