Ti.Network.createHTTPClient

Question

我可以在Titanium移动应用程序中创建使用8080以外的端口的http客户端吗？

我的代码：

var clietn = Ti.Network.createHTTPClient({
    onload: function(e){
      ....
      ....
    },
    onerror: function(e){
      ....
      ....
    },

    timeout: 3000
});

client.open("GET", Ti.App.Properties.getString('srvName', '192.168.4.248:8888'));

client.send(JSON.stringify({....}));

不能按我的意愿行事;

Titanium告诉我：
