生成静态页 评论敏感词

图书5

在BLL里面

   /// 将商品的信息生成静态页面
        /// </summary>
        public void CreateHtmlPage(int id)
        {
            Model.Book model=dal.GetModel(id);
            //获取模板文件
            string template = HttpContext.Current.Request.MapPath("/Template/BookTemplate.html");
            string fileContent = File.ReadAllText(template);
            fileContent = fileContent.Replace("$title", model.Title).Replace("$author", model.Author).Replace("$unitprice",model.UnitPrice.ToString("0.00")).Replace("$isbn",model.ISBN).Replace("$content",model.ContentDescription).Replace("$bookId",model.Id.ToString());
            string dir = "/HtmlPage/" + model.PublishDate.Year + "/" + model.PublishDate.Month + "/" + model.PublishDate.Day + "/";
            Directory.CreateDirectory(Path.GetDirectoryName(HttpContext.Current.Request.MapPath(dir)));
            string fullDir = dir + model.Id + ".html";
            File.WriteAllText(HttpContext.Current.Request.MapPath(fullDir), fileContent, System.Text.Encoding.UTF8);

        }

在服务器端静态页面

将商品的详细信息页面建成静态页面。

静态页面好处：（1）.访问速度快（2）：减轻数据库的压力。所以是网站优化中很重要的手段。

劣势：

什么样的内容适合做成静态页面？

经常访问的页面，但是页面的内容不是经常修改的。

 public partial class CreateStaticPage : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (IsPostBack)
            {
                BLL.BookManager bll = new BLL.BookManager();
                List<Model.Book> list = bll.GetModelList("");
                foreach (Model.Book bookModel in list)
                {
                    bll.CreateHtmlPage(bookModel.Id);
                }
            }
        }
    }

评论

 public class BookComment : IHttpHandler
    {
        BLL.BookCommentManager bll = new BLL.BookCommentManager();
