本文主要讲述了在asp.net mvc中,页面静态化的方法。对于网站来说,生成纯html静态页面除了有利于seo外,还可以减轻网站的负载能力和提高网站性能。
1.先付上封装好生成静态页的原代码:
public class common { #region 获取模板页的html代码 /// <summary> /// 获取页面的html代码 /// </summary> /// <param name="url">模板页面路径</param> /// <param name="encoding">页面编码</param> /// <returns></returns> public static string gethtml(string url, system.text.encoding encoding) { byte[] buf = new webclient().downloaddata(url); if (encoding != null) { return encoding.getstring(buf); } string html = system.text.encoding.utf8.getstring(buf); encoding = getencoding(html); if (encoding == null || encoding == system.text.encoding.utf8) { return html; } return encoding.getstring(buf); } /// <summary> /// 获取页面的编码 /// </summary> /// <param name="html">html源码</param> /// <returns></returns> public static system.text.encoding getencoding(string html) { string pattern = @"(?i)\bcharset=(?<charset>[-a-za-z_0-9]+)"; string charset = regex.match(html, pattern).groups["charset"].value; try { return system.text.encoding.getencoding(charset); } catch (argumentexception) { return null; } } #endregion #region 用于生成html静态页 /// <summary> /// 创建静态文件 /// </summary> /// <param name="result">html代码</param> /// <param name="createpath">生成路径</param> /// <returns></returns> public static bool createfilehtmlbytemp(string result, string createpath) { if (!string.isnullorempty(result)) { if (string.isnullorempty(createpath)) { createpath = "/default.html"; } string filepath = createpath.substring(createpath.lastindexof(@"\")); createpath = createpath.substring(0, createpath.lastindexof(@"\")); if (!directory.exists(createpath)) { directory.createdirectory(createpath); } createpath = createpath + filepath; try { filestream fs2 = new filestream(createpath, filemode.create); streamwriter sw = new streamwriter(fs2, new system.text.utf8encoding(false));//去除utf-8 bom sw.write(result); sw.close(); fs2.close(); fs2.dispose(); return true; } catch (exception ex) { throw ex; } } return false; } #endregion #region 调用静态模板,并且传递数据模型实体类 创建html静态页 /// <summary> /// 解析模板生成静态页 /// </summary> /// <param name="temppath">模板地址</param> /// <param name="path">静态页地址</param> /// <param name="t">数据模型</param> /// <returns></returns> public static bool createstaticpage<t>(string temppath, string path, t t) { try { //获取模板html string templatecontent = gethtml(temppath, system.text.encoding.utf8); //初始化结果 string result = string.empty; //解析模板生成静态页html代码 result = razor.parse(templatecontent, t); //创建静态文件 return createfilehtmlbytemp(result, path); } catch (exception e) { throw e; } } #endregion }
2.调用方法(创建一个多线程去执行,效果会更好):
//实例化调用方法 task tk = new task(createstatichtml); tk.start(); //静态调用方法 task.factory.startnew(() => createstatichtml());
3.封装好的静态方法:
/// <summary> /// 创建静态页面 /// </summary> public void createstatichtml() { using (banglientities bangli = new banglientities()) { view_home view_home = new view_home(); view_home.commandadextendlist = dal.commandaddal.instance(bangli).getinit().tolist(); view_home.newslist = bangli.news.orderbydescending(u => u.adddatetime).take(5).tolist(); view_home.newsextendlist = dal.newsdal.instance(bangli).getinit().orderbydescending(u => u.adddatetime).take(5).tolist(); view_home.news = dal.newsdal.instance(bangli).getinit().where(u => u.id == 3).singleordefault(); string templatecontent = common.gethtml(server.mappath("/views/sourcehtml/home/index.cshtml"), system.text.encoding.utf8); //初始化结果 string result = string.empty; //解析模板生成静态页html代码 result = razor.parse(templatecontent, view_home); //创建静态文件 common.createfilehtmlbytemp(result, server.mappath("/resource/manage/html/home/index.html")); } }
4.如首页执行时,可以在执行action前去执行一个过滤器:
public class myfirsthomeattribute:actionfilterattribute { public override void onactionexecuting(actionexecutingcontext filtercontext) { var context = filtercontext.httpcontext; context.session["isstatichtml"] = false; string path = context.server.mappath("/resource/manage/html/home/index.html"); if (system.io.file.exists(path)) { string html = system.io.file.readalltext(path); context.response.write(html); context.session["isstatichtml"] = true; context.response.end(); } } }
5.执行首页:
[myfirsthome] public actionresult index() { view_home view_home = null; var isstatichtml = convert.toboolean(session["isstatichtml"]); if (!isstatichtml) { view_home = new view_home(); using (banglientities bangli = new banglientities()) { view_home.commandadextendlist = dal.commandaddal.instance(bangli).getinit().tolist(); view_home.newsextendlist = dal.newsdal.instance(bangli).getinit().orderbydescending(u => u.adddatetime).take(5).tolist(); } return view(view_home); } else { return null; } }
说明:可以让一个超链接或跳转地址直接跳转到一个html的静态页面,速度会更快;
