連接接收握手迴應之前關閉目前對WebSocket

我嘗試我的客戶通過網絡JS連接的插座，但我有這個錯誤連接接收握手迴應之前關閉目前對WebSocket

getUser.js:29 WebSocket connection to 'ws://localhost:8005/wsserver.js' failed: Connection closed before receiving a handshake response

但看看我的代碼：

getUser.js

var sock = new WebSocket("ws://localhost:8005/wsserver.js"); 

$('#data1').append("alors"); 

sock.onopen = function (event) {  
    $('#data').append("server status opened" + event.currentTarget.URL); 
    sock.send(JSON.stringify("coucou")); 
    console.log("sended"); 
}; 
sock.onmessage = function (event) { 
$('#data').append(event.data); 
console.log(event.data); 
}; 
sock.onerror = function(error) { 
    console.log('WebSocket Error: ' + error); 
};

而服務器端代碼是： wsserver.js

var WebSocketServer = require("ws").Server; 
var ws = new WebSocketServer({ port: 8005 }); 

console.log("Server started..."); 

ws.on('connection', function (ws) { 
    console.log("Browser connected online...") 

    ws.on("message", function (str) { 
    var ob = JSON.parse(str); 
    switch(ob.type) { 
    case 'text': 
     console.log("Received: " + ob.content) 
     ws.send('{ "type":"text", "content":"Server ready."}') 
     break; 
    case 'image': 
     console.log("Received: " + ob.content)   
     console.log("Here is an apricot...") 
     var path ="apricot.jpg"; 
     var data = '{ "type":"image", "path":"' + path + '"}'; 
     ws.send(data); 
     break; 
     } 
    }) 

    ws.on("close", function() { 
     console.log("Browser gone.") 
    }) 
});

但錯誤仍在這裏，我不明白爲什麼

採取腳本部分遠離你的客戶端：

VAR襪子=新的WebSocket（「WS：//本地主機：8005」）;

服務器應用程序正在該端口中運行，並且您只需連接到該端口。
