Microsoft Silverlight
Microsoft Silverlight是一个跨浏览器的、跨平台的插件，为网络带来下一代基于.NET Framework的媒体体验和丰富的交互式应用程序。Silverlight提供灵活的编程模型，并可以很方便地集成到现有的网络应用程序中。Silverlight可以对运行在Mac或Windows上的主流浏览器提供高质量视频信息的快速、低成本的传递。
起始页面为Login.aspx，固定调试端口为49441。需要配合自己淘宝开放平台的应用的回调页面URL来调整。
ashx代码：
（说明：代码中ITopClient为淘宝接口TopSdk.dll中的类，此例子使用的ItemsOnsaleGetRequest是用于获取销售中的商品，response.Body是获取到的数据信息）
复制代码
代码如下:public class OnsaleGet : IHttpHandler
{</p> <p> public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
ITopClient client = new DefaultTopClient(Config.ServerURL, Config.Appkey, Config.Secret);</p> <p> ItemsOnsaleGetRequest req = new ItemsOnsaleGetRequest();
req.Fields = "approve_status,num_iid,title,nick,type,cid,pic_url,num,props,valid_thru,list_time,price,has_discount,has_invoice,has_warranty,has_showcase,modified,delist_time,postage_id,seller_cids,outer_id";
ItemsOnsaleGetResponse response = client.Execute(req, Config.Top_session);</p> <p>
if (response.IsError)
{
context.Response.Write("[错误：查询函数执行失败]");
}
else
{
context.Response.Write(response.Body);
}</p> <p> }</p> <p> public bool IsReusable
{
get
{
return false;
}
}
}
前端SL获取数据信息的方法
复制代码
代码如下:void GetList()
{
string absolutePath = HtmlPage.Document.DocumentUri.AbsoluteUri;
string address = absolutePath.Substring(0, absolutePath.LastIndexOf('/'))
+ "/TaoBaoHandler/OnsaleGet.ashx";</p> <p> Uri uri = new Uri(address);</p> <p> WebClient client = new WebClient();
client.DownloadStringCompleted += (sender, e) =>
{
if (e.Error == null)
{
System.Xml.Linq.XElement.Parse(e.Result);//字符串转为xml
ItemsOnsaleGetResponse list = SerializeHelper.DeserializeFromString<ItemsOnsaleGetResponse>(e.Result);//反序列化
if (list != null)
{
if (list.Items != null && list.Items.Count > 0)
{
MessageBox.Show(list.Items[0].NumIid.ToString());
}
}
else
{
}
}
else
{
MessageBox.Show(e.Error.Message);
}
};
client.DownloadStringAsync(uri);
}
SerializeHelper
序列化部分是自定义的一个类
复制代码
代码如下:public class SerializeHelper
{
private SerializeHelper() { }</p> <p> #region Serialize</p> <p> /// <summary>
/// 序列化实体
/// </summary>
/// <typeparam name="T">实体类型</typeparam>
/// <param name="data">实体</param>
/// <returns>xml字体串</returns>
public static string Serialize<T>(T data)
{
try
{
var serializer = new XmlSerializer(typeof(T));</p> <p> XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
XmlWriterSettings writerSettings = new XmlWriterSettings();
writerSettings.OmitXmlDeclaration = true;
StringWriter stringWriter = new StringWriter();
using (XmlWriter xmlWriter = XmlWriter.Create(stringWriter, writerSettings))
{
serializer.Serialize(xmlWriter, data, ns);
}
string xmlText = stringWriter.ToString();</p> <p> return xmlText;
}
catch (InvalidOperationException ex)
{
if (ex.Message != "")
{ }
}</p> <p> return string.Empty;
}</p> <p> public static string SerializeList<T>(List<T> list)
{
try
{
var serializer = new XmlSerializer(typeof(List<T>));</p> <p> XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
XmlWriterSettings writerSettings = new XmlWriterSettings();
writerSettings.OmitXmlDeclaration = true;
StringWriter stringWriter = new StringWriter();
using (XmlWriter xmlWriter = XmlWriter.Create(stringWriter, writerSettings))
{
serializer.Serialize(xmlWriter, list, ns);
}
string xmlText = stringWriter.ToString();</p> <p> return xmlText;
}
catch
{ }</p> <p> return string.Empty;
}</p> <p> #endregion</p> <p> #region Deserializer</p> <p> /// <summary>
/// 反序列化实体
/// </summary>
/// <typeparam name="T">实体类型</typeparam>
/// <param name="xml">xml字体串</param>
/// <returns>实体</returns>
public static T DeserializeFromString<T>(string xml)
{
T theObject;
try
{
XmlReader reader = XmlReader.Create(new StringReader(xml));
var serializer = new XmlSerializer(typeof(T));
theObject = (T)serializer.Deserialize(reader);
reader.Close();
return theObject;
}
catch
{ }</p> <p> return default(T);
}</p> <p> public static List<T> DeserializeListFromString<T>(string xml)
{
try
{
var serializer = new XmlSerializer(typeof(List<T>));
StringReader reader = new StringReader(xml);</p> <p> List<T> list = (List<T>)serializer.Deserialize(reader);
reader.Close();</p> <p> return list;
}
catch (InvalidOperationException ex)
{
if (ex.InnerException.Message != "")
{ }
}</p> <p> return null;
}</p> <p> #endregion
}
淘宝相关的数据类型
TopModels模块中的ItemsOnsaleGetResponse,Item,ItemImg,Location等这些实体是从TopSdk.dll中找到相应的定义粘贴出来供Silverlight下使用的。如图
web.config中的配置
配置沙箱环境和正式环境的选择，以及AppKey和AppSecret
复制代码
代码如下:<appSettings>
<!--IsSandBox 1=沙箱开启 0=非沙箱(正式环境) -->
<add key="SandBox" value="1"/>
<!--应用 信息-->
<add key="AppKey" value="1012596959"/>
<add key="AppSecret" value="sandboxc5928dd8d1cfa3bb4f7d87e33"/></p> <p> </appSettings>
另外，web中的那些Client.cs和Config.cs则是从淘宝示例Demo中来的。
最终数据的获取如下：
