HttpClient中的GetStringAsync方法在WP8中引发异常

问题描述

最近，我为WP8开发了一个应用程序，开始时一切正常.但是，从昨天开始，我在尝试从URL检索 RSS数据时遇到错误.

Recently, I develop an App for WP8 and at the begining all worked OK. However, since yesterday nigth I was getting an error when trying to retrieve the RSS data from an url.

这是我用来获取数据的代码的一部分:

This is part of the code I use to get the data:

try
{
   HttpClient client = new HttpClient();
   var result = await client.GetStringAsync("http://www.scoop.it/t/recycling-by-miguel18/rss.xml");
   var parseResult = XDocument.Parse(result);
   . . .
}
catch (Exception ex)
{
   throw new Exception("Error: " + ex.Message);
}

其中source是包含用于获取 RSS数据的网址的字符串.如前所述，一开始它工作正常，我能够使用它来处理数据.

Where source is the string which contain the url to get the RSS data.As commented, at the begining it was working OK, I was able to get the data in work with it.

现在，它引发以下错误:响应状态代码不表示成功:404().

Now, it raise the following error:Response status code does not indicate success: 404 ().

如果我将网址直接放置到任何浏览器中，都可以看到 RSS供稿.因此，我不了解代码的问题.我有点迷茫.

If I put the url directly to any browser I can see the RSS feeds. So, I don't undertand what would be wrong with the code. I am a little lost.

如果您能帮助我找出问题所在，那将非常有帮助

If you can help me to figure out what is wrong that would be very helpful
