Detailed example of using Razor engine to generate static pages (ASP.NET MVC)

I have recently been studying ASP.NET MVC to generate static pages, so today can be considered a study note!

Implementation principles and steps:

1. Find the corresponding view through ViewEngines.Engines.FindView. If it is a partial view, use: ViewEngines.Engines.FindPartialView;

2. Set the Model in the context object;

3. Call the Render() method of the view and save the rendering results to the physical static file;

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; 
    } 
  } 
}

AjaxResult is encapsulated by itself A class, you can also replace it with your own encapsulated class.

  public class AjaxResult
  {
    public bool IsSucess { get; set; }
    public string Body { get; set; }
  }
