ASP.NET 根据现有动态页面生成静态Html

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：

             foreach (var page in pageList)
             {
                 string html = ReadHtml(string.Format("pageName.aspx?ID={0}", page.ID));
                 html = ReplaceListAndSingle(html);
                 WriteHtml(string.Format("pageName_{0}.html", page.ID), html);
             }

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)); }
        }
