探索自己实现页面基类.打造快速页面.
在很多时候。我门需要一种页面。这种页面不需要回送。为了速度。不需要使用服务器控件。必须保持高响应。他只要做动态显示。有不能做成静态页面。比如一些vip的文章显示。投票查看了。
webform框价功能强大。但是看看一个system.web.ui.page的源码。

不要忘记，*.cs内的类在继承了这个page类。最后*.aspx在编译成一个类 在继承*.cs内的类。 在编译*.aspx类的时候。会分析html字符串，把所有的html标签和文字写到类内。并用服务器控件的多少来分割他。最后建立一个控件树。
现在我门的思路是这样的 。想要用一个类来完全实现页面输出。这个类不需要继承system.web.ui.page。个人觉得在管道上切入不现实。最后选择在http处理程序上入手。所有的请求在进入http处理程序以后，检测访问路径。通过不同的路径去调用不同类的实例。不同类的内部在调用不同的模板。或者直接输出。直接产生输出结果。在http处理程序上返回。
我的想法是把处理工厂类封装起来。但是如何让所有的页面类在第一次访问前有一个实例，我想了好久，还是想不出好的办法。于是决定把处理工厂类开放出来。这样所有的问题就全解决。我们先在逻辑层定义一个处理工厂类
处理工厂类
#region 处理工厂类 /**//// <summary> /// 处理工厂类 /// </summary> public sealed class TempletHandler : RunTimeTemplet, IHttpHandlerFactory, IRequiresSessionState { 从接口继承。不需要修改这个函数#region 从接口继承。不需要修改这个函数 public IHttpHandler GetHandler(HttpContext context, string requestType, string url, string pathTranslated) { return RunTimeTemplet.HandlerFactory(url, this); } #endregion 为实现接口写上#region 为实现接口写上 public void ReleaseHandler(IHttpHandler handler) { } #endregion 类文件和要显示页面匹配的函数。只要扩展这个函数就可以了。函数调用会自动进行#region 类文件和要显示页面匹配的函数。只要扩展这个函数就可以了。函数调用会自动进行 protected override BaseTempletHandler AddTempletClass(string FilePath) { BaseTempletHandler BackObject = null; switch (FilePath) { case @"/WebSiteTest/Run/Test1.aspx": //要显示得文件可以是根本不存在得文件 BackObject = new CreatTempletHandler(); break; case @"/WebSiteTest/Run/Test2.aspx": //对应第二个模板aa2.htm BackObject = new SecendTempletHandler(); break; case @"/WebSiteTest/Run/Test1.pdf": BackObject = new CreatTempletHandler(); break; case @"/WebSiteTest/Run/Test2.pdf": BackObject = new SecendTempletHandler(); break; default: throw new Exception("错误:" + FilePath + "没有和任何一个类文件结合"); } return BackObject; } #endregion } #endregion
TempletHandler 类就是开放在外的处理工厂类 ，下面我门在配置文件内注册他
<httpHandlers>
<add verb="*" path="Run/*.aspx" type="BusinessTest.TempletHandler,BusinessTest"/>
<add verb="*" path="Run/*.pdf" type="BusinessTest.TempletHandler,BusinessTest"/>
</httpHandlers>
表示在站点的run目录上所有的*.aspx文件和*.pdf文件全部转成我门的页面类处理。而实际上run目录上没有任何文件。
case @"/WebSiteTest/Run/Test1.aspx":
BackObject = new CreatTempletHandler();
这两句表示对/WebSiteTest/Run/Test1.aspx的请求 由CreatTempletHandler类处理。AddTempletClass函数一般只执行一次。在缓存没消失的情况下。他是不会被多次调用的。
CreatTempletHandler 类。他来全部负责/WebSiteTest/Run/Test1.aspx请求的输出。这种页面类只要继承BaseTempletHandler类就好了。页面布局你可以用模板来控制。显示你可以用标签来控制。当然要是想在提高速度。也可以不使用模板。并且不使用模板也绝对不会带来任何性能损失。
CreatTempletHandler，页面最终输出类的执行顺序是先是protected override void Page_Load(ref TempletReplet objILabel)函数执行。要是使用模板那在函数内部protected override void Page_Init(ref TempletReplet objILabel)函数被调用,记住Page_Init只执行一次。等Page_Load执行完毕以后 在执行其他的标签解析函数。最后 和成一个完整的页面输出。
第一个页面类
#region 第一个页面类 public sealed class CreatTempletHandler : BaseTempletHandler { Page_Load事件函数#region Page_Load事件函数 protected override void Page_Load(ref TempletReplet objILabel) { 获取变量，要是不使用模板完全可以忽略#region 获取变量，要是不使用模板完全可以忽略 if (HttpContext.Current.Request.QueryString.Count > 0) { this.PageId = HttpContext.Current.Request.QueryString[0]; } else { this.PageId = "7"; } this.UserId = "9"; System.Collections.Hashtable ht = new System.Collections.Hashtable(); ht.Add("PageId", this.PageId); ht.Add("UserId", this.UserId); DataSet ds = new DataSet(); ds.ReadXml(HttpContext.Current.Server.MapPath(@"/WebSiteTest/templet/BadWord.xml")); sss objss = new sss(); objss.SS = "<font Color=red>信息载体类属性一</font>"; objss.SS1 = "<font Color=blue>信息载体类属性二.你好 我不是个稻草人</font>"; #endregion 使用模板部分，可以不使用#region 使用模板部分，可以不使用 objILabel = new CreatTempletHandler(); objILabel.ReadFilePath = HttpContext.Current.Server.MapPath(TempletFilePath); objILabel.Obj = objss; objILabel.LabelDatatable = ds.Tables[0]; objILabel.LabelHashtable = ht; #endregion } #endregion 标签函数执行体#region 标签函数执行体 /**//// <summary> /// 无参数函数 ((sss)this.Obj) 这样使用载体类 /// </summary> /// <returns></returns> public string show() { return "无参数标签执行结果" + ((sss)_this.Obj).SS + " " + ((sss)_this.Obj).SS1; } //一个参数函数 public string tag(string aa) { return "一个参数函数:" + aa; } //二个参数函数 public string tag_two(string aa, string bb) { return "二个参数函数:" + aa + " 和 " + bb; } public string Get_Test1() { return "你好我开始研究" + " " + ((sss)_this.Obj).SS1; } #endregion 标签，标签解析函数影射事件#region 标签，标签解析函数影射事件 /**//// <summary> /// 标签，标签解析函数影射事件 /// </summary> protected override void Page_Init(ref TempletReplet objILabel) { //如果要使用模板。那么写这个函数。要是不用模板，那么让这个函数为空就可以 CreatTempletHandler.AddLabel("无参书签", new Run_0(this.show), 0, ref objILabel); CreatTempletHandler.AddLabel("第一个书签", new Run_0(this.Get_Test1), 0, ref objILabel); CreatTempletHandler.AddLabel("一个参数书签", new Run_1(this.tag), 1, ref objILabel); CreatTempletHandler.AddLabel("二个参数书签", new Run_2(this.tag_two), 2, ref objILabel); //好象这样就可以保留委托对象了 应为委托执行函数和委托是定义在一个类内 _this = objILabel;//如果要使用载体类，那么加这个语句。否则不需要加。其实不加这个理论上也可以使用载体类的。但我没测试 } #endregion public static string TempletFilePath = @"/WebSiteTest/templet/aa1.htm";//要指定的模板，当然不使用模板也完全可以 TempletReplet _this = null;//如果要使用载体类，那么加这个语句。否则不需要加,其实不加这个理论上也可以使用载体类的。但我没测试 //定义变量 string PageId, UserId; } #endregion
这种方法页面和一般的继承page类的页面那个快，那个节省资源我没有做具体测试。其实这就是动态程序集。和内存中的对象在合并字符串速度上的比较。用页面类。可以保证在高并发情况下安全性 。就是80，90个请求同时到达，返回的结果绝对不会互相冲突。但是我没有加上多线程。应为我现在也搞不清楚在aspx页面并发很高的情况下。多线程异步回调是发生在那。处理管道上有管道池。那异步回调是发生在管道上，还是http处理程序上，或者是http处理模块上。或者是*.aspx编译成的类上。以后我加上多线程。对方法异步回调。这样我相信页面类的处理能力将更强大。
