欢迎大家! 我已经和websocket聊天了,最棒的是它包含了php,为此我以不同的方式安装了这个websocket(服务器端)。
问题如下,当我运行服务器时,我从localhost / path打开页面..浏览器出错,
"未捕获的ReferenceError:io未定义"在: " var socket = io();"来自index.php,chat1.rar文件
服务器端似乎可以正常工作, node chat.js
我已经看了一周如何解决它,
我在下面提到的代码下面。
chat.js(服务器端)
var express = require( 'express' );
var http = require('http');
var socket = require('socket.io');
var bodyParser = require('body-parser')
var PORT = process.env.PORT || 8080;
var fs= require('fs');
var app = express();
var server = http.createServer( app );
var io = socket.listen( server );
io.on('connection',function(socket){
var channel = 'channel-a';
socket.join(channel);
socket.on('message',function(msj){
io.sockets.in(channel).emit('message',msj,socket.id);
});
socket.on('disconnect',function(){
console.log("Desconectado : %s",socket.id);
});
});
server.listen( 1334, function() {
console.log('lisning to port 1334');
});
和index.php(客户端)

改变这个:
<script src="node_modules/socket.io/node_modules/socket.io-client/dist/socket.io.js">
要:
<script src="/socket.io/socket.io.js">
看看会发生什么。
