http和websocket如何共用80端口
后端代码
const http = require('http');
const WebSocket = require('ws');
const url = require('url');
var fs = require("fs");
const server = http.createServer(function(request, response) {
var file = fs.createReadStream(__dirname + '/index.html');
response.writeHead(200, {'Content-Type' : 'text/html;charset=utf8'});
file.pipe(response);
});
const wss = new WebSocket.Server({ noServer: true });
wss.on('connection', function connection(ws, req) {
wss.on('message', function incoming(data) {
sendAll(data)
});
function sendAll(mes) {
wss.clients.forEach(function each(client) {
if (client.readyState === WebSocket.OPEN) {
client.send(mes);
}
});
}
});
server.on('upgrade', function upgrade(request, socket, head) {
const pathname = url.parse(request.url).pathname;
if (pathname === '/ws') {
wss.handleUpgrade(request, socket, head, function done(ws) {
wss.emit('connection', ws, request);
});
} else {
socket.destroy();
}
});
server.listen(80);前端代码调用如下
new WebSocket('ws://localhost/ws')完整代码查看github
