在android phonegap中使用jquery ajax从服务器获取数据

Question

嗨,我正在开发一个Android的应用程序(使用phonegap,html5和javascript),它将自己连接到远程mysql数据库.我创建了一个RESTful(codeigniter)Web服务来访问mysql数据库,然后Android应用程序可以调用Web服务来获取或发布数据到数据库,使用XML或JSON作为数据格式.

在使用jquery ajax的web浏览器中,我成功获得了结果但在android应用程序中没有得到响应.

jQuery.ajax({
url : 'http://10.10.1.129/index.php/apiauth/auth/?'+jQuery("#form-login").serialize(),
async :true,
cache :false,
/*crossDomain : true,*/
dataType : 'jsonp',
success:function(data){
    alert(data);
    }  
});

在服务器中:

require APPPATH.'/libraries/REST_Controller.php';
    class Apiauth extends REST_Controller
    {
        function auth_get()
        {
            $this->load->model('mauth');
            $username   = $this->input->get('username') ? $this->input->get('username') : $this->get('username');
            $password   = $this->input->get('password') ? $this->input->get('password') : $this->get('password');
            $auth       = $this->mauth->getUserLogin('*',$username,$password);
            $row        = $auth->row();
            if($row){
                $data   = array('username'=>$row->username, 'fullname'=>$row->fullname,'error'=>FALSE);
            }else{
                $data   = array('error'=>true);
            }
            $this->response($data, 200);
        }

您是否添加了具有ajax请求中指定的IP地址的访问源？此文件位于application-dir/res/xml/config.xml中,默认情况下允许使用localhost,但您在使用时需要添加其他主机.所以你的config.xml应该是这样的

<?xml version="1.0" encoding="utf-8"?>
