问题描述
在我的其他问题中，我发现有不是 Windows 手机的白名单.
In my other question I found out that there is no whitelist for windows phones.
现在我正在寻找一种本机代码解决方法，但我从未为 Windows 手机编写过一行本机代码.所以对我来说并不容易.我想我可以下载这样的页面:
Now I am looking for a native code workaround but I have never written a line of native code for windows phones. So it's not easy for me. I think I can download a page like this:
void GetAirportData()
{
var url = new Uri("http://server.example.com/data.php", UriKind.Absolute);
var webClient = new WebClient();
webClient.OpenReadCompleted += new OpenReadCompletedEventHandler(webClient_OpenReadCompleted);
webClient.OpenReadAsync(url, url);
}
但是如何将这些数据获取到我的 javascript 应用程序中?
But how can a get this data to my javascript app?
推荐答案
这里有一个解决方法.以下代码是实现跨域呼叫功能的 Phonegap 命令.
Here is a workaround. The following code is a Phonegap command that implements Cross Domain Call functionality.
using System;
using System.IO;
using System.Net;
using System.Runtime.Serialization;
using WP7CordovaClassLib.Cordova;
using WP7CordovaClassLib.Cordova.Commands;
using WP7CordovaClassLib.Cordova.JSON;
namespace Cordova.Extension.Commands //namespace is predefined, don't change it!
{
public class Cdc : BaseCommand //Cross domain call
{
[DataContract]
public class CdcOptions
{
[DataMember(Name = "path")]
public string Path { get; set; }
}
public void Call(string args)
{
CdcOptions options = JsonHelper.Deserialize<CdcOptions>(args);
var url = new Uri(options.Path, UriKind.Absolute);
var webClient = new WebClient();
webClient.OpenReadCompleted += (s, e) =>
{
if (e.Error != null)
{
DispatchCommandResult(new PluginResult(PluginResult.Status.ERROR, "Error"));
return;
}
//Stream -> string
var sr = new StreamReader(e.Result);
var result = sr.ReadToEnd();
DispatchCommandResult(
new PluginResult(PluginResult.Status.OK, result));
};
webClient.OpenReadAsync(url, url);
}
}
}
在客户端测试:
<script type="text/javascript">
function cdc(path, success, fail) {
PhoneGap.exec(
success, //success
fail, //fail
"Cdc", //service
"Call", //action
path //args
);
};
function onDeviceReady(e) {
cdc(
{
path: "http://stackoverflow.com/questions/9291809/workaround-for-missing-whitelist-in-phonegap-for-windows-phone"
},
function (arg) {
document.getElementById('test').innerHTML = arg;
}, function (arg) {
document.getElementById('test').innerHTML = arg;
});
}
document.addEventListener("deviceready", onDeviceReady, false);
</script>
</head>
<body>
<div id="test"></div>
</body>
</html>
