我正在使用node.js和express.js,并且试图将socket.io添加到我的一个.ejs文件中,但是当我这样做时,出现了一些奇怪的错误:
Failed to load resource: the server responded with a status of 404 (Not Found) socket.io/?EIO=3&transport=polling&t=MV6f2K2
Failed to load resource: the server responded with a status of 404 (Not Found) socket.io/?EIO=3&transport=polling&t=MV6f2cR
然后每秒:
GET https://www.mywebsite.eu/socket.io/?EIO=3&transport=polling&t=MV6f2cR 404 (Not Found) socket.io.js:7
有我的文件: app.js:
const fs = require('fs');
const express = require('express');
const app = express();
const http = require('http').Server(app);
const fileUpload = require('express-fileupload');
var io = require('socket.io')(http);
.....
var router = express.Router();
var pathView = __dirname + "/views/";
app.use(express.urlencoded({extended: true}));
app.use(express.json());
const listenPort = 8000;
app.set('view engine', 'ejs');
app.use(express.static('public'));
app.use('/public', express.static('public'));
app.use('/scripts', express.static(__dirname + '/node_modules/'));
//SOCKET IO PART
io.on('connection', function(socket){
console.log('a user connected');
});
//SOCKET IO PART
..........
app.get & app.post requests
..........
app.use( "/", router);
// Not found
app.use("*",function(req,res){
res.setHeader('Content-Type', 'text/html');
res.status(404).send('Page introuvable !');
});
// Run server
app.listen(listenPort, function () {
console.log('Example app listening on port ' + listenPort )
})
profile.ejs:
.....content of the page(it's working well).......
<%- include('scripts') -%>
<script src="/scripts/socket.io/socket.io.js"></script>
</html>
<script>
var socket = io();
</script>
我不得不提到我是从socket.io-client复制了socket.io.js的,如果不这样做,我会将其放入socket.io中,那我会在devtools中遇到404文件丢失的错误。
希望不需要其余代码,我没有添加它,因为它很多,而且与socket.io无关。
答案 0 :(得分:1)
我认为您应该尝试将其分解以找出您的问题。显然您没有到达插座。
尝试拥有这样的服务器:
if [ git merge-base --is-ancestor source destination ] ...
和客户:
var express = require('express')
var app = express()
var server = require('http').Server(app)
var io = require('socket.io')(server)
io.on('connection', function(socket) {
console.log('Socket did connect');
});
server.listen(8080)
如果这行得通,那就应该添加其余的代码。 Ejs不会成为问题,因为它在投放之前已被编译为常规HTML。
问题是,如果您的客户端在与服务器不同的域(或端口)上运行。如果是这样,则必须在客户端站点的io()内部定义它,例如:var socket = io();
