大家都知道,生成静态页的方法有两种,第一种是使用c#在后台硬编码,第二种是读取模板文件,使用字符串代替。总体来讲第一种方法代码量比较大,维护起来有点困难。生成静态页的目的是为了提高用户体验度,加快访问速度。
使用静态页面还有如下好处:
1、 安全:使用静态页面,用户访问的使没有任何操作功能的html页面,可以说从安全性方面大大提高了程序及服务器的安全。
2、 快速:用户访问的是提前生成好的静态页面,使用户对页面的请求瓶颈只受io的限制而不会有其他方面的影响。
3、 降低服务器,数据库负载:因为用户访问的是静态页,对承载静态页的服务器配置要求降低了许多,同时,不会因为过大的访问量,造成数据库服务器负载过重等问题。
下面分享asp.net新闻列表生成静态页之批量和单页生成。前期准备,需要新建一个文件夹。。前台展示:/new/default.aspx 这个页面放的就是动态的新闻列表数据。
先看下图:
不多说了上代码
这里要说明一下,我用的aspnetpager分页控件,需要设置一下
<webdiyer:aspnetpager id="aspnetpager1" runat="server" firstpagetext="首页" lastpagetext="末页" nextpagetext="下一页" numericbuttoncount="10" onload="aspnetpager1_load" onpagechanged="aspnetpager1_pagechanged1" pagesize="13" prevpagetext="上一页" font-bold="false" font-size="13px" cssclass="badoo" urlpaging="true" currentpagebuttonposition="center" pagingbuttonspacing="5px" enableurlrewriting="true" urlrewritepattern="news_{0}.html" showmorebuttons="false" showpageindexbox="never" > </webdiyer:aspnetpager>
需要设置三个地方:
urlpaging="true" 设置启用url来传递分页信息 enableurlrewriting="true" 启用url重写 urlrewritepattern="news_{0}.html" 设置分页url重写格式
static.ashx页面代码
