使自定义的aspx页面仅用于部分SharePoint站点

早上 小熊发给我的一个链接，国外TechNet论坛上的一篇回帖。 http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=2779241&SiteID=17&mode=1

我们往往会碰到这样的需求：

我们可以创建aspx页面，将其部署到12\TEMPLATE\LAYOUTS目录下，并通过feature的方式来安装（如果有DLL的话，拷贝到对应的SharePoint站点的\bin目录中）。
这样做没有什么问题，但是_layouts目录是所有站点都可以访问的。我需要达到这样的效果： http://mossdemo/onesite/customapp/custompage1.aspx
而现在的实现，却是:
http://mossdemo/onesite/_layouts/custompage1.apsx
而且，更严重的是，如果我这么试：
http://mossdemo/anothersite/_layouts/custompage1.aspx
同样起作用。但事实上我只在onesite上安装的该feature。

解决办法：

假设我们的feature目录叫做customapp,完整的路径为 C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES\customapp

下面有如下的内容：
2个文件
feature.xml
elements.xml
1个文件夹，叫custompages。用来存放我们的aspx页面。其中有两个页面文件：
custompage1.aspx
custompage2.aspx

我们可以这样组织feature.xml内容：

<? xml version="1.0" encoding="utf-8"  ?>
< feature  id ="{AAA4124D-2A89-43df-8427-F820D7B20CC9}"  title ="FileUploadDemo"  xmlns ="http://schemas.microsoft.com/sharepoint/"  hidden ="FALSE"  scope ="Web"  version ="1.0.0.0"  description ="Loads a file into sharepoint site"  creator ="" >
< elementmanifests >
< elementmanifest  location ="elements.xml"    />
< elementfile  location ="custompages\custompage1.aspx"    />
< elementfile  location ="custompages\custompage2.aspx"    />
</ elementmanifests >
</ feature >

elements.xml内容如下：

<? xml version="1.0" encoding="utf-8"   ?>
< elements  xmlns ="http://schemas.microsoft.com/sharepoint/" >
< module  path ="custompages"  name ="CustomPages" >
< file  path ="custompage1.aspx"  name =""  type ="Ghostable"  url ="custompages/custompage1.aspx"    />
< file  path ="custompage2.aspx"  name =""  type ="Ghostable"  url ="custompages/custompage2.aspx"    />
</ module >
</ elements >

为了测试，custompage1.aspx的内容很简单，只是显示SPWeb的Title。内容如下：

< %@ Assembly  Name ="Microsoft.SharePoint.ApplicationPages, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"  % >

< %@ Page  Language ="C#"  
    MasterPageFile ="~masterurl/default.master"  % >

< %@ Import  Namespace ="Microsoft.SharePoint.ApplicationPages"  % >
< %@ Register  TagPrefix ="SharePoint"  Namespace ="Microsoft.SharePoint.WebControls"
    Assembly ="Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"  % >
< %@ Register  TagPrefix ="Utilities"  Namespace ="Microsoft.SharePoint.Utilities"  Assembly ="Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"  % >
< %@ Import  Namespace ="Microsoft.SharePoint"  % >

< %@ Import  Namespace ="Microsoft.SharePoint"  % >

< script  runat ="server" >

    protected void Page_Load(object sender, EventArgs e)
    {
        this.lbtest.Text = SPContext.Current.Web.Title;
    }
</ script >

< asp:Content  ID ="Content1"  ContentPlaceHolderID ="PlaceHolderPageTitle"  runat ="server" >
     < SharePoint:EncodedLiteral  ID ="EncodedLiteral1"  runat ="server"  Text ="自定义页1"
        EncodeMethod ='HtmlEncode'   />
</ asp:Content >
< asp:Content  ID ="Content2"  ContentPlaceHolderID ="PlaceHolderPageTitleInTitleArea"
    runat ="server" >
     < SharePoint:EncodedLiteral  ID ="EncodedLiteral2"  runat ="server"  Text ="定制内容"
        EncodeMethod ='HtmlEncode'   />
</ asp:Content >
< asp:Content  ID ="Content3"  ContentPlaceHolderID ="PlaceHolderAdditionalPageHead"  runat ="server" >
     < meta  name ="Robots"  content ="NOINDEX "   />
     < meta  name ="SharePointError"  content =""   />
</ asp:Content >
< asp:Content  ID ="Content4"  ContentPlaceHolderID ="PlaceHolderMain"  runat ="server" >
     < table  width ="100%"  border ="0"  class ="ms-titleareaframe"  cellpadding ="0" >
         < tr >
             < td  valign ="top"  width ="100%"  style ="padding-top: 10px"  class ="ms-descriptiontext" >
                     < span  class ="ms-descriptiontext" >
                     < asp:Label  ID ="lbtest"  runat ="server"  Text ="" ></ asp:Label >
                     </ span >
             </ td >
         </ tr >
     </ table >

</ asp:Content >

一切就绪后，安装feature：

stsadm -o installfeature -name customapp

然后到某个SharePoint站点（如 http://mossdemo/onesite）上，激活该网站功能（名为FileUploadDemo的就是）。
 
现在，就可以通过如下的方式访问我们的aspx页面了：
 http://mossdemo/onesite/custompages/custompage1.aspx
