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:

asp.net新闻列表生成静态页之批量和单页生成2

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

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Text; using System.IO; using System.Net; using System.Data; namespace Web.admin.ashx { /// <summary> /// Static 生成静态页 /// </summary> public class Static : IHttpHandler { public void ProcessRequest(HttpContext context) { string url = context.Request["geturl"]; string path = context.Request["getpath"]; string id = context.Request["id"]; string act = context.Request["act"]; string page = context.Request["pages"]; string pagecount = context.Request["pagecouts"]; string table = context.Request["table"]; string str = ""; if (act == "0") { //生成当前选中项 string ids = id.Substring(0, (id.Length - 1)); string[] s_id = ids.Split(','); for (int i = 0; i < s_id.Length; i++) { string path2 = context.Server.MapPath("../../" + path + s_id[i] + ".html"); str = CreateHTML("http://localhost:4216/" + url + s_id[i], path2); //这里必须是拼接的绝对路径 string urls = "http://localhost:4216/" + path + s_id[i] + ".html"; //这里必须是拼接的绝对路径 string sql = string.Format("update {0} set Static =1,Url='{1}' where id={2}", table, urls, s_id[i]); if (new DBTool.DB().RunSqlGetRowCount(sql) > 0) { } } context.Response.Write(str); context.Response.End(); } if (act == "1") { //生成当前页列表 string path2 = context.Server.MapPath("../../" + path + page + ".html"); str = CreateHTML("http://localhost:4216/" + url + page, path2); context.Response.Write(str); context.Response.End(); } if (act == "2") { //生成全部列表 int count = Convert.ToInt32(pagecount); for (int i = 1; i <= count; i++) { string path2 = context.Server.MapPath("../../" + path + i + ".html"); str = CreateHTML("http://localhost:4216/" + url + i, path2); } context.Response.Write(str); context.Response.End(); } if (act == "3") { //生成全部项 string sqlsel =string.Format("select Id from {0}",table); DataTable dt = new DBTool.DB().RunSqlGetDataTable(sqlsel); if (dt.Rows.Count > 0) { string idall = ""; for (int i = 0; i < dt.Rows.Count; i++) { idall += dt.Rows[i]["Id"].ToString()+","; } string ids = idall.Substring(0, (idall.Length - 1)); string[] s_id = ids.Split(','); for (int ii = 0; ii < s_id.Length; ii++) { string path2 = context.Server.MapPath("../../" + path + s_id[ii] + ".html"); str = CreateHTML("http://localhost:4216/" + url + s_id[ii], path2); string urls = "http://localhost:4216/" + path + s_id[ii] + ".html"; string sql = string.Format("update {0} set Static =1,Url='{1}' where id={2}", table, urls, s_id[ii]); if (new DBTool.DB().RunSqlGetRowCount(sql) > 0) { } } context.Response.Write(str); context.Response.End(); } } } public string CreateHTML(string strurl, string path) { string str = ""; StreamReader sr; StreamWriter sw = null; try { WebRequest HttpWebRequest = WebRequest.Create(strurl); WebResponse HttpWebResponse = HttpWebRequest.GetResponse(); sr = new StreamReader(HttpWebResponse.GetResponseStream(), System.Text.Encoding.GetEncoding("utf-8")); string strHtml = sr.ReadToEnd(); sw = new StreamWriter(path, false, System.Text.Encoding.GetEncoding("utf-8")); sw.WriteLine(strHtml); sw.Flush(); sw.Close(); str = "生成成功!"; } catch (Exception ex) { str = "生成失败,失败原因" + ex.Message+"。"; } return str; } public bool IsReusable { get { return false; } } } }

后台生成前台代码

<div> <table border="0" cellpadding="0" cellspacing="0"> <tr> <td width="13%"><input type="text" runat="server" id="text_word" placeholder="请输入关键字"/></td> <td width="5%"> <asp:Button ID="Button1" runat="server" Text="搜索" CssClass="suborange" /> </td> <td width="82%"> <a href="list.aspx">查看全部</a></td> </tr> </table> <table width="100%" border="0" cellpadding="0" cellspacing="0"><tr> <th width="30"></th> <th width="60" data-field="id" data-url="newslist.aspx" >ID<img id="lab_id" src="images/a2.png" /></th> <th width="200" data-field="Name" data-url="newslist.aspx" >名称<img id="lab_Name" src="images/a2.png" /></th> <th width="200" data-field="Dir" data-url="newslist.aspx">地址<img id="lab_Dir" src="images/a2.png" /></th> <th width="150" data-field="Static" data-url="newslist.aspx">静态化<img id="lab_Static" src="images/a2.png" /></th> <th>操作</th> </tr> <asp:Repeater ID="R1" runat="server" OnItemDataBound="R1_ItemDataBound" ><ItemTemplate> <tr id='tr_<%#Eval("id")%>'> <td><label id='labe_<%#Eval("id")%>'><asp:CheckBox ID="chkItem" runat="server" ToolTip='<%#Eval("id")%>'></asp:CheckBox></label><input type="hidden" id="text_id" runat="server" value='<%#Eval("id")%>' /></td> <td> <%#Eval("id") %></td> <td> <%#Eval("Name") %></td> <td> <a href="javascript:;" data-id='<%#Eval("id") %>' data-field='Dir' data-table='HotelInfo' data-url="newslist.aspx"> <%#Eval("Dir") %></a></td> <td> <asp:Label ID="lab_state" runat="server" Text='<%#Eval("Static") %>'></asp:Label> </td> <td> <a href="<%#Eval("Url") %>" target="_blank">查看</a> <%--data-table data-fild 为复制数据的表明和字段--%> <span data-id="<%#Eval("id") %>" data-table="users" data-fild="Name,PassWord" data-url="list.aspx" data-itemid="<%# Container.ItemIndex + 1%>">更多操作</span> </td></tr> </ItemTemplate> </asp:Repeater></table> <div id="div_none" runat="server" visible="false">很抱歉,暂无数据。</div> <div id="button"> <input type="button" name="button" value="删除" /> <input type="button" name="button" value="全选" /> <input type="button" name="button" value="取消" /> <asp:Button ID="Button3" runat="server" Text="添加" CssClass="btn btn82 btn_add" PostBackUrl="addarticle.aspx" /> </div> <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" UrlRewritePattern="" UrlPaging="true" CurrentPageButtonPosition="Center" PagingButtonSpacing="5px" ShowFirstLast="False" ShowMoreButtons="False" ShowPageIndexBox="Never" > </webdiyer:AspNetPager> <div> <asp:Label ID="lab_num" runat="server" Text=""></asp:Label> </div> <div></div> <input type="hidden" id="text_delid" runat="server" /> <input type="hidden" id="text_page" value='<%=page() %>' /> <input type="hidden" id="text_pagecount" runat="server" /> <br />

生成静态列表:

<input type="button" value="生成当前页列表" data-href="newslist.aspx" data-act="1" data-url="news/default.aspx" data-path="news/news_" /> <input type="button" value="生成全部列表" data-href="newslist.aspx" data-act="2" data-url="news/default.aspx" data-path="news/news_" /> <a href="../news/news_1.html" target="_blank">查看新闻列表</a>

生成静态页:

<input type="button" value="生成当前选中项" data-href="newslist.aspx" data-act="0" data-url="newsel/default.aspx"newsel/newsel_" data-table="HotelInfo"/> <%-- <input type="button" value="生成全部项" data-href="newslist.aspx" data-act="3" data-table="HotelInfo" data-url="newsel/default.aspx"newsel/newsel_" />--%> <div id="divdialog"></div> <div id="loading"><div id="message"></div></div> </div>

以上内容是asp.net新闻列表生成静态页之批量和单页生成的全部内容,还有生成文章静态页,在这里我要提醒大家生成文章的静态页的方法给这个是不一样的,请继续关注本网站,我会持续更新的。谢谢大家阅读我的作品。
