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.顯示信息

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);

}
}
