最近在研究ASP.NET MVC生成静态页,那么今天也算个学习笔记吧!

实现原理及步骤:

1.通过ViewEngines.Engines.FindView查找到对应的视图,如果是部分视图,则用:ViewEngines.Engines.FindPartialView;

2.设置上下文对象里的Model;

3.调用视图的Render()方法,将渲染结果保存到物理静态文件;

using System; using System.IO; using System.Text; using System.Web.Mvc;  namespace Whir.Foundation.UI {   /// <summary>   ///   描述:静态页面生成帮助类   /// </summary>   public class StaticPageHelper   {     /// <summary>     ///   根据View视图生成静态页面     /// </summary>     /// <param name="htmlPath">存放静态页面所在绝对路径</param>     /// <param name="context">ControllerContext</param>     /// <param name="viewPath">视图名称</param>     /// <param name="masterName">模板视图名称</param>     /// <param name="model">参数实体模型</param>     /// <param name="html">返回信息</param>     /// <param name="isPartial">是否分布视图</param>     /// <returns>生成成功返回true,失败false</returns>     public static AjaxResult GenerateStaticPage(string viewPath,                           string htmlPath,                           ControllerContext context, object model = null, bool isPartial = false,                           string masterName = "")     {       var ajaxResult = new AjaxResult();       try       {         //创建存放静态页面目录                       if (!Directory.Exists(Path.GetDirectoryName(htmlPath)))         {           Directory.CreateDirectory(Path.GetDirectoryName(htmlPath));         }         //删除已有的静态页面         if (File.Exists(htmlPath))         {           File.Delete(htmlPath);         }         ViewEngineResult result = null;         if (isPartial)         {           result = ViewEngines.Engines.FindPartialView(context, viewPath);         }         else         {           result = ViewEngines.Engines.FindView(context, viewPath, masterName);         }          if (model != null)         {           context.Controller.ViewData.Model = model;         }          /*          * 设置临时数据字典作为静态化标识          * 可以在视图上使用TempData["IsStatic"]来控制某些元素显示。          */         if (!context.Controller.TempData.ContainsKey("IsStatic"))         {           context.Controller.TempData.Add("IsStatic", true);         }          if (result.View != null)         {           using (var sw = new StringWriter())           {             var viewContext = new ViewContext(context,                              result.View,                              context.Controller.ViewData,                              context.Controller.TempData, sw);              result.View.Render(viewContext, sw);              string body = sw.ToString();             File.WriteAllText(htmlPath, body, Encoding.UTF8);             ajaxResult.IsSucess = true;             ajaxResult.Body = "存放路径:" + htmlPath;           }         }         else         {           ajaxResult.IsSucess = false;           ajaxResult.Body = "生成静态页面失败!未找到视图!";         }       }       catch (IOException ex)       {         ajaxResult.IsSucess = false;         ajaxResult.Body = ex.Message;       }       catch (Exception ex)       {         ajaxResult.IsSucess = false;         ajaxResult.Body = ex.Message;       }       return ajaxResult;     }   } }
