我想用一些IP连接到放置amazone实例的Web套接字。我可以将我的Web套接字与ip ip连接起来，并与google rest客户端应用程序进行端口连接，并且效果很好。截屏：

但是，如果我想用Java脚本连接它，则无法连接。2-3个月前可以正常工作。我没有改变和事情，但现在无法正常工作。如果我想与Firefox连接，则会产生错误。这是我的代码：-

function init() {
           var host = "ws://XX.XX.XXX.XXX:XXXX"; // SET THIS TO YOUR SERVER


                try {
                  var socket = new WebSocket(host);
                   // alert('WebSocket - status ' + socket.readyState);
                    log('WebSocket - status ' + socket.readyState);

                    socket.onopen = function (msg) {
                        alert('open');
                        alert("Welcome - status " + this.readyState);
                        log("Welcome - status " + this.readyState);

                        if (this.readyState != 1)
                        {
                            reconnect();
                        }
                    };
                    socket.onmessage = function (msg) {
                      //  alert("Received: " + msg.data);
                        log("Received: " + msg.data);

                    };
                    socket.onclose = function (msg) {
                     //   alert("Disconnected - status " + this.readyState);
                        log("Disconnected - status " + this.readyState);
                    };
                } catch (ex) {
                    alert(ex);
                    log(ex);
                }
                $("msg").focus();
            }

这是警报状态0，并且控制台中显示错误：-

Firefox can't establish a connection to the server at ws://XX.XX.XXX.XXX:XXXX.


var socket = new WebSocket(host);

我会尝试您的代码，并且对我来说工作正常，请在以下网页上进行测试：https : //www.websocket.org/echo.html，可能对测试有用。但是我也发现了这个问题：websocket-rails，websocket握手错误，也许也有帮助。但是，我只是将您代码中的主机更改为：“ ws：//echo.websocket.org”，并且一切正常。希望您能找到解决方案，并且此信息对您有所帮助。这是我用于测试的代码：

function init() {
var host = "ws://echo.websocket.org"; 
    try {
      var socket = new WebSocket(host);
       alert('WebSocket - status ' + socket.readyState);
        socket.onopen = function (msg) {
            alert('open');
            alert("Welcome - status " + this.readyState);

            if (this.readyState != 1)
            {
                reconnect();
            }
        };
        socket.onmessage = function (msg) {
          alert("Received: " + msg.data);
        };
        socket.onclose = function (msg) {
           alert("Disconnected - status " + this.readyState);
        };
    } catch (ex) {
        alert(ex);

    }
    $("msg").focus();
}
