我正在使用 Websockets 在三星 Gear S 上的 Tizen 中实现 MQTT 协议。虽然在 IDE 模拟器中一切正常，但在手表上运行它时，我总是收到 SecurityError: DOM Exception 18。

访问来源设置：

我错过了什么？感谢帮助！

这里使用了 MQTT 代码。是使用 JavaScript 库 mqttws31.ja von IBM（基本上是 PAHO）

var client = null;
var topic = "sensor";
var qos = 2;

var options =
{

    // connection attempt timeout in seconds
    timeout : 3,

    // Gets Called if the connection has successfully been established
    onSuccess : function()
    {
        $("#mqttout").append("mqttconnect: Connected" + "<br />");

        /*
         * client.subscribe(topic, { qos : qos });
         * 
         */

        client.subscribe("adl",
        {
            qos : qos
        });

    },

    // Gets Called if the connection could not be established
    onFailure : function(message)
    {
        $("#mqttout").append(
                "mqttconnect: Connection failed: " + message.errorMessage
                        + "<br />");
    }

};

function mqttclear()
{
    $("#mqttout").empty();
}

var isens = 0;

// Host: broker.hivemq.com
// Port: 1883
// Websocket Port: 8000

// Host: test.mosquitto.org
// Port: 1883
// Websocket Port: 8080
var mqttservers = [
{
    "server" : "broker.hivemq.com",

        client.connect(options);
