Unity3D 网站查找在 Unity3D 4.7.2 中返回 nil

Question

这是我的代码。        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://itunes.apple.com/lookup?id=1218822890");        request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;        using(HttpWebResponse response = (HttpWebResponse)request.GetResponse())            using(Stream stream = response.GetResponseStream())                using(StreamReader reader = new StreamReader(stream))        {            string textRead = reader.ReadToEnd();            Debug.Log("\nData Read = "); Debug.Log(textRead);        }我试图从统一代码读取游戏的网站链接并读取应用程序价格。它返回 nil... call 有什么问题？
