现有动态页面的格式都是类似 pageName.aspx?ID=1的格式,后面由于发布服务器的原因,要求将动态页面转为静态html后上传。
首先根据页面生成的格式,枚举获取页面html:
1 foreach (var page in pageList)
2 {
3 string html = ReadHtml(string.Format("pageName.aspx?ID={0}", page.ID));
4 html = ReplaceListAndSingle(html);
5 WriteHtml(string.Format("pageName_{0}.html", page.ID), html);
6 }
读取asp.net页面:
public static string ReadHtml(string sourceurl)
{
try
{
System.Net.WebRequest myRequest = System.Net.WebRequest.Create(sourceurl);
System.Net.WebResponse myResponse = myRequest.GetResponse();
using (Stream stream = myResponse.GetResponseStream())
{
using (StreamReader sr = new StreamReader(stream, Encoding.GetEncoding("utf-8")))
{
return sr.ReadToEnd();
}
}
}
catch (Exception ex)
{ throw new Exception(string.Format("ReadHtml出错:{0}", ex.Message)); }
}
使用正则替换页面内的动态链接:
public static string ReplaceListAndSingle(string html)
{
html = Regex.Replace(html, @"_list\.aspx\?ID=(\d*)", "_list_$1.html", RegexOptions.IgnoreCase);
html = Regex.Replace(html, @"_single\.aspx\?ID=(\d*)", "_single_$1.html", RegexOptions.IgnoreCase);
return html.Replace(".aspx", ".html");
}
动态页面格式为 pageName_list.aspx?ID=1 与 pageName_single.aspx?ID=1,正则替换后变为静态格式:pageName_list_1.html 与 pageName_single_1.html。
将替换后的页面html写入文件:
public static bool WriteHtml(string url, string html)
{
try
{
using (StreamWriter sw = new StreamWriter(HttpContext.Current.Server.MapPath(url), false, Encoding.GetEncoding("utf-8")))
{
sw.WriteLine(html);
sw.Close();
}
return true;
}
catch (Exception ex)
{ throw new Exception(string.Format("WriteHtml出错:{0}", ex.Message)); }
}
