WebSocket连接到'ws：//192.168.5.78：8080 / Chat-WebSocket / server.php'失败：连接建立错误：net :: ERR_CONNECTION_REFUSED

Question

大家好，                我试图通过Web套接字连接以替换项目中的Ajax日志轮询，因为它的开销太大，尝试了一个简单的Websocket聊天代码，问题是我无法使握手工作在浏览器控制台中执行获取以下错误  WebSocket与'ws：//192.168.5.78：8080 / Chat-WebSocket / server.php'的连接失败：连接建立错误：net :: ERR_CONNECTION_REFUSED

我已经在本地计算机Client上设置了客户端代码：

http://192.168.5.66/test/zaheer/Chat-WebSocket/

并且服务器代码在另一台本地计算机上

192.168.5.78

这是我的代码

Client :
<script language="javascript" type="text/javascript">  
    //create a new WebSocket object.
    var msgBox = $('#message-box');
    //var wsUri = "ws://192.168.5.78:8080/Chat-WebSocket/server.php";   
    var websocket = new WebSocket("ws://192.168.5.78:8080/Chat-WebSocket/server.php");
    //websocket = new WebSocket(wsUri); 

    websocket.onopen = function(ev) { // connection is open 
        msgBox.append('<div class="system_msg" style="color:#bbbbbb">Welcome to my "Demo WebSocket Chat box"!</div>'); //notify user
    }

    // Message received from server
    websocket.onmessage = function(ev) {
        var response        = JSON.parse(ev.data); //PHP sends Json data

        var res_type        = response.type; //message type
        var user_message    = response.message; //message text
        var user_name       = response.name; //user name
        var user_color      = response.color; //color

        switch(res_type){
            case 'usermsg':
                msgBox.append('<div><span class="user_name" style="color:' + user_color + '">' + user_name + '</span> : <span class="user_message">' + user_message + '</span></div>');
                break;
            case 'system':
                msgBox.append('<div style="color:#bbbbbb">' + user_message + '</div>');
                break;
        }
        msgBox[0].scrollTop = msgBox[0].scrollHeight; //scroll message 

    };

    websocket.onerror   = function(ev){ msgBox.append('<div class="system_error">Error Occurred - ' + ev.data + '</div>'); };

    websocket.onclose   = function(ev){ msgBox.append('<div class="system_msg">Connection Closed</div>'); }; 

    //Message send button
    $('#send-message').click(function(){
        send_message();
    });

    //User hits enter key 
    $( "#message" ).on( "keydown", function( event ) {
      if(event.which==13){
          send_message();
      }
    });

    //Send message
    function send_message(){
        var message_input = $('#message'); //user message text
        var name_input = $('#name'); //user name

        if(message_input.val() == ""){ //empty name?
            alert("Enter your Name please!");
            return;
        }

            alert("Enter Some message Please!");
            return;
        }

        //prepare json data
        var msg = {
            message: message_input.val(),

            color : '<?php echo $colors[$color_pick]; ?>'
        };
        //convert and send data to server
        websocket.send(JSON.stringify(msg));    
        message_input.val(''); //reset message input
    }
