处理401未授权的错误在Windows Phone Phonegap [英] handle 401 unauthorized error on windows Phone with Phonegap

问题描述

我正在Windows phone 7上创建一个应用程序与phonegap，需要在服务器上的验证。当我们使用正确的用户名和密码登录时，我们获得了200状态。一切工作。但是，如果我们在登录或密码错误，服务器发送回401错误。这冻结了我的应用程序。我需要杀死它，并重新启动它。所以不是很实践。

I'm creating an application with phonegap on windows phone 7, that need an authentification on a server. When we log with the correct username and password, we got a 200 status. And everything works. But if we make a mistake on the login or the password, the server send us back a 401 error. This freeze my application. I need to kill it and restart it. So not very practice.

我在我的电脑上用fiddler检查响应，手机接收到401错误，我在我的代码上管理这个错误。这在我的其他平台（Android和ios）上工作。

I check the response with fiddler on my computer and the phone receive the 401 error, and I manage this error on my code. this works on my other platform (android and ios).

所以我想知道如何管理这个错误。也许我可以在windows phone项目上改变一个cs文件来处理这个错误。

So I would like to know how I can manage this error. Maybe I can change a cs file on the windows phone project to handle this error.

欢迎任何帮助

这是代码

$.support.cors = true;
    $.ajax({
        type: "POST",
        dataType: "HTTP/1.1",
        url: 'https://xxx.xxx-xxx.com/issue/wrap',
        data: data,
        cache: 'false',
        async: false,
        error: function (data) {
            console.log(data);
            console.log("error");
            //navigator.notification.alert(data);
        },
        complete: saveToken
    });

感谢

我遇到了同样的问题，我创建的唯一的解决方案是实现一个Phonegap插件。

I've encountered the same problem and the only solution I founded is to implement a Phonegap plugin.

这里是我使用的C＃代码： p>

Here is the C# code I use :

namespace WPCordovaClassLib.Cordova.Commands
{
    [DataContract]
    public class PhonegapWindowsPhonePostObject
    {
        [DataMember(IsRequired = false, Name = "yourParamName1")]
        public string yourParam1;

        [DataMember(IsRequired = false, Name = "yourParamName2")]
        public string yourParam2;
    }

    public class PhonegapWindowsPhonePost: BaseCommand
    {
        public void post(string options)
        {
            PhonegapWindowsPhonePostObject pwppo = JSON.JsonHelper.Deserialize<PhonegapWindowsPhonePostObject>(options);

            try
            {
                System.Windows.Deployment.Current.Dispatcher.BeginInvoke(() =>
                {
                    var data = "YOUR DATA STRING HERE"; //use the pwppo object to retrieve your parameters
                    var url = "URL OF THE SERVICE HERE";


                    WebClient wc = new SharpGIS.GZipWebClient();
                    var URI = new Uri(url);
                    wc.Encoding = Encoding.UTF8;
                    wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
                    wc.UploadStringCompleted += new UploadStringCompletedEventHandler(wc__UploadStringCompleted);
                    wc.UploadStringAsync(URI, "POST", data);
                });

            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }
        void wc__UploadStringCompleted(object sender, UploadStringCompletedEventArgs e)
        {
            try
            {
                if (e.Result != null)
                    this.DispatchCommandResult(new PluginResult(PluginResult.Status.OK, e.Result));
                else
                    this.DispatchCommandResult(new PluginResult(PluginResult.Status.ERROR, "Error 401"));
            }
            catch (Exception ex)
            {
                this.DispatchCommandResult(new PluginResult(PluginResult.Status.ERROR, ex.Message));
                // no http status code available
            }
        }
    }
}

这里是从您的应用程序调用pluging的Javascript代码：

And here is the Javascript code to call the pluging from your app :

function loginToWebService(yourParam1, yourParam2) {

    var options = { "yourParamName1": yourParam1, "yourParamName2": yourParam2};
    cordova.exec(success, error,"PhonegapWindowsPhonePost","post", options);
}

我希望它会帮助你。

注意：Phonegap 2.8版本不能解决与发布说明相反的问题...

Note : the Phonegap 2.8 version does not solve the problem contrary to what said the release note...

再见！
