Phonegap android ajax不适用于android设备 - Phonegap android ajax not works on android device

Phonegap android ajax not works on android device

我创建了一个示例，其中我做了一个简单的ajax调用来发送数据到android应用程序。下面是ajax函数:

function testServer()
{
    var db = window.openDatabase("Database", "1.1","Test Exmple", 500000);
    $.ajax({
        url: urlServer+'getTest.php',
        contentType : 'application/json',
        dataType: 'json',
        data : {companyCode : 'Template'},
        success : function(data){
            alert(data);
        },
        error : function(xhr, ajaxOptions, thrownError) {
            console.log("Server is not responding... Please try after sometime"+thrownError);
        }
    });
}

下面是PHP代码:

<?
 require_once ('connect.php');
 include("AES.class.php");
 $companyurl =$_REQUEST['companyCode'];
 $data = $companyurl;
 require_once('JSON.php');
 $json = new Services_JSON();
  echo ($json->encode($data));
 ?>

下面是logcat:

但它在模拟器上运行得很好。

谁能帮我找出问题所在吗?

Thanks in advance

参考:http://rickluna.com/wp/2012/04/solving-the-connection-to-the-server-was-unsuccessful-error-in-androidphonegap/

super.setIntegerProperty("loadUrlTimeoutValue", 60000);
super.loadUrl("file:///android_asset/www/index.html");

看起来像是跨域请求。因此，尝试将数据类型从'json'更改为'jsonp'。这里我更新了你的代码:

function testServer()
{
var db = window.openDatabase("Database", "1.1","Test Exmple", 500000);
$.ajax({
    url: urlServer+'getTest.php',
    contentType : 'application/json',
    dataType: 'jsonp',
    data : {companyCode : 'Template'},
    success : function(data){
        alert(data);
    },
    error : function(xhr, ajaxOptions, thrownError) {
        console.log("Server is not responding... Please try after     sometime"+thrownError);
    }
});
}

伙计们，感谢你们的帮助，代码中没有错误，问题是防火墙，只是在防火墙中访问端口，它工作得很好。再次感谢您的帮助。
