asp.net 讀取 搜狐 的圖書

1.建立一個讀取request對象，讀取html

代碼如下：

View Code

   public class HelpOauth
    {
        private static string BTtile = "<div class=\"txtC\" id=\"txtBg\">";
        public static string SetUrlToXMLToFile(string url)
        {
            var strXml = "";
            var m_uri = new Uri(url);  
            HttpWebRequest rqst = (HttpWebRequest)WebRequest.Create(m_uri);
            rqst.AllowAutoRedirect = true;
            //rqst.ContentType = "xml";
            rqst.MaximumAutomaticRedirections = 3;
            rqst.UserAgent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";
            rqst.KeepAlive = true;
            rqst.Timeout = 100000;
            rqst.Method = "GET";

            HttpWebResponse rsps = (HttpWebResponse)rqst.GetResponse();
            Stream sm = rsps.GetResponseStream();
            Encoding cding = Encoding.GetEncoding("gb2312");

            if (sm.CanRead) {

                 strXml = new StreamReader(sm, cding).ReadToEnd();  

            }
           int i= strXml.IndexOf(BTtile);
           int n = strXml.IndexOf(@"</div>", i+6);
           n = strXml.IndexOf(@"</div>", n+6);

           n = strXml.IndexOf(@"</div>", n+6);
           n = strXml.IndexOf(@"</div>", n+6);
           n = strXml.IndexOf(@"</div>", n+6);
           n = strXml.IndexOf(@"</div>", n+6);
           strXml = strXml.Substring(i, n - i+6);
           strXml=strXml.Replace("<div class=\"page\"><a href=\"", "<div class=\"page\"><a href=\"?page=");
return strXml;
        }
    }

2.引入搜狐的css

<link href="http://www.sohu.com/upload/style/pp.css" rel="stylesheet" type="text/css" />

3.顯示資訊

代碼如下：

View Code

    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string strXml = "http://lz.book.sohu.com/" + (Request.QueryString["page"] == null ? "chapter-23699-118311506.html" : Request.QueryString["page"]);
            strXml = HelpOauth.SetUrlToXMLToFile(strXml);
            Literal1.Text = strXml;
            //System.Data.DataSet oauthentry = HelpOauth.CXmlToDataSet(strXml);
            //System.Data.DataSet ds=HelpOauth.TestXml();
            //this.GridView1.DataSource = ds.Tables[0];
            //this.GridView1.DataBind();
            //this.Response.Write(strXml);

        }
    }
