我嘗試了許多不同的npm web套接字庫(WebSocket,ws,express-ws和更多),並且在它們的每個人中我都有同樣的問題。當我嘗試發送websocket消息時,連接關閉。 我沒有問題接收messeges,只發送。Node.js中的Websocket連接在發送時關閉
這裏是使用Express和WS的某個庫的測試的一個簡單的例子: Node.js的側:
var server = require('http').createServer()
, url = require('url')
, WebSocketServer = require('ws').Server
, wss = new WebSocketServer({ server: server })
, express = require('express')
, app = express()
, port = 8080
, fs = require('fs');
app.use(function (req, res) {
var index = fs.readFileSync('./interface/index.html');
res.end(index);
});
wss.on('connection', function connection(ws) {
var location = url.parse(ws.upgradeReq.url, true);
console.log('open ws');
ws.on('message', function incoming(message) {
console.log('received: %s', message);
ws.send('test back');
});
ws.on('close', function() {
console.log('ws connection closed.');
})
});
server.on('request', app);
server.listen(port, function() { console.log('Listening on ' + server.address().port) });
和瀏覽器側(」 ./interface/index.html 「):
window.WebSocket = window.WebSocket || window.MozWebSocket;
var port = 8080;
var ip = window.location.hostname;
var connection;
connection = new WebSocket('ws://' + ip + ':' + port);
connection.onopen = function() {
// connection is opened and ready to use
console.log('Web socket connection with', ip + ':' + port);
//sendQueue(msgQueue);
};
connection.onerror = function (error) {
// an error occurred when sending/receiving data
console.log('Web socket erorr with', ip + ':' + port + ':', error);
};
connection.onmessage = function (message) {
// try to decode json (I assume that each message from server is json)
console.log("Received ws");
// handle incoming message
};
connection.onclose = function(){
console.log("Web socket connection lost.");
};
function sendws() {
connection.send("test");
console.log("sent ws");
return false;
}

我不知道爲什麼會發生這種情況。我將Node.js更新爲6.7。 在Windows 10上運行。 我很感激幫助! 謝謝!
