一个是一个页面转换的类,该类通过静态函数Changfile()来实现,动态页面到静态页面的转换。
using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Text; using System.IO; /**//// /// Summary description for HtmlProxy /// public class HtmlProxy ...{ public HtmlProxy() ...{ } public static bool ChangeFile(int id) ...{ string filename = HttpContext.Current.Server.MapPath("Post_" + id + ".html"); |
Stream st = GetFileStream(filename); //如果文件存在并且读取成功 if (st != null) ...{ using (st) ...{ StreamToStream(st, HttpContext.Current.Response.OutputStream); return true; //Response.End(); } } else ...{ StringWriter sw = new StringWriter(); HttpContext.Current.Server.Execute("ForumDetail.aspx?PID=" + id, sw); string content = sw.ToString(); |
try ...{ using (FileStream fs = new FileStream(filename, FileMode.Create, FileAccess.Write, FileShare.Write)) ...{ using (StreamWriter stw = new StreamWriter(fs, HttpContext.Current.Response.ContentEncoding)) ...{ stw.Write(content); } } return true; } catch ...{ return false; } } } private static Stream GetFileStream(string filename) ...{ try ...{ DateTime dt = File.GetLastWriteTime(filename); TimeSpan ts = dt - DateTime.Now; if (ts.TotalHours >1) ...{ //一小时后过期 return null; } return new FileStream(filename, FileMode.Open, FileAccess.Read, FileShare.Read); } catch ...{ return null; } } static public void StreamToStream(Stream src, Stream dst) ...{ byte[] buf = new byte[4096]; while (true) ...{ int c = src.Read(buf, 0, buf.Length); if (c == 0) return; dst.Write(buf, 0, c); } } } 在页面文件中,ForURL.aspx的后台代码如下: protected void Page_Load(object sender, EventArgs e) ...{ try ...{ int id = int.Parse(Request.QueryString["PID"]); if(HtmlProxy.ChangeFile(id)) ...{ Response.Redirect("Post_" + id + ".html"); } else ...{ Response.Redirect("Post.aspx?PID=" + id ); } } catch ...{ } |
