Question

当我尝试从windows phone 8应用程序访问在localhost上运行的ASP.NET Web Api 2应用程序时，我遇到了问题。我已经尝试并寻找了很多例子如何做但没有结果。我用Fiddler测试了我的api并且它有效。我测试从Web应用程序访问它，它工作，但当我尝试从Windows Phone 8应用程序访问它时，它没有。你能告诉我如何配置我的Windows Phone 8模拟器来访问它吗？提前谢谢。

Answer 1

模拟器是一个虚拟机，所以＆＃34; localhost＆＃34;在手机应用程序内部意味着模拟器本身，而不是您正在运行Web服务的主机。要访问它，您必须在本地网络中提供主机的实际IP地址，而不是＆＃34; localhost＆＃34;。您可以通过在cmd控制台中运行ipconfig来查看您的IP。

这是一篇关于访问Windows Phone 8中的web api方法的详细文章

Calling Web API from a Windows Phone 8

这里具体说明如何从Web API获取数据

 string apiUrl = @"http://www.contoso.com/api/Books";
 WebClient webClient = new WebClient();
            webClient.Headers["Accept"] = "application/json";
            webClient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(webClient_DownloadCatalogCompleted);
            webClient.DownloadStringAsync(new Uri(apiUrl));

 private void webClient_DownloadCatalogCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
        try
        {
            this.Items.Clear();
            if (e.Result != null)
            {
                var books = JsonConvert.DeserializeObject<BookDetails[]>(e.Result);
                int id = 0;
                foreach (BookDetails book in books)
                {
                    this.Items.Add(new ItemViewModel()
                    {
                        ID = (id++).ToString(),
                        LineOne = book.Title,
                        LineTwo = book.Author,
                        LineThree = book.Description.Replace("\n", " ")
                    });
                }
                this.IsDataLoaded = true;
            }
        }
        catch (Exception ex)
        {
            this.Items.Add(new ItemViewModel()
            {
                ID = "0",
                LineOne = "An Error Occurred",
                LineTwo = String.Format("The following exception occured: {0}", ex.Message),
                LineThree = String.Format("Additional inner exception information: {0}", ex.InnerException.Message)
            });
        }
    }
