我们学习来看一下Response对象。其实我们前面的教程中一直都在使用这个对象的Write方法。
这里我们用Response对象设置cookie。
?
打开vb6,新建Activex Dll工程。工程名修改为fCom,类名修改为fZ5
引用“Microsoft Active Server Pages Object”对象库。
创建两个组件事件：OnStartPage以及OnEndPage
在事件OnStartPage中创建类ScriptingContent的一个引用。
实例化类ScriptingContent。
?
代码如下：
Option Explicit
'对象的声明
Dim myResponse As Response
Dim myRequest As Request
Dim myApplication As Application
Dim myServer As Server
Dim mySession As Session
?
??? '当组件被创建的时候会触发这个事件
Public Sub OnStartPage(myScriptingContent As ScriptingContext)
???? '进行对象的实例化
???? Set myResponse = myScriptingContent.Response
???? Set myRequest = myScriptingContent.Request
???? Set myServer = myScriptingContent.Server
???? Set myApplication = myScriptingContent.Application
???? Set mySession = myScriptingContent.Session
End Sub
?
??? '当组件被销毁的时候触发这个事件
Public Sub OnEndPage()
???? '销毁对象
???? Set myResponse = Nothing
???? Set myRequest = Nothing
???? Set myServer = Nothing
???? Set myApplication = Nothing
???? Set mySession = Nothing
End Sub
?
'从页面中设置Cookie,组件中得到
Public Sub GetCookie()
??? Dim myitem
??? '全部信息
??? For Each myitem In myRequest.Cookies
??????? myResponse.Write myitem & ": " & myRequest.Cookies.Item(myitem)
??????? myResponse.Write "
"
??? Next
???
??? '单个信息
??? myResponse.Write "其中用户姓名是" & ": " & myRequest.Cookies("username")
??? myResponse.Write "
"
??? myResponse.Write "其中用户年龄是" & ": " & myRequest.Cookies("age")
??? myResponse.Write "
"
End Sub
'组件中设置cookie,页面中得到
Public Sub SetCookie()
??? myResponse.Cookies("com_username") = "龙卷风"
??? myResponse.Cookies("com_age") = 26
??? myResponse.Expires = #9/13/2004#
End Sub
?
编译成Dll文件,系统自动会注册。
否则就手工注册 Regsvr32 f:"test"fcom.dll
?
测试
打开visual interdev6.0,生成一个fz5.asp文件
<%@ Language=VBScript %>
<%
dim obj
set obj=server.CreateObject ("fcom.fz5")
call obj.setcookie()
Response.Write Request.Cookies("com_username")
Response.Write "
"
Response.Write Request.Cookies("com_age")???
Response.Write "
"
?
'下面在页面中设置Cookie
Response.Cookies("username") = "龙卷风"
Response.Cookies("age") = 26
call obj.GetCookie()
?
%>
?
配置好虚拟目录，在ie中执行fc5.asp文件，可以看到
龙卷风
26
age: 26
username: 龙卷风
com_age: 26
com_username: 龙卷风
其中用户姓名是: 龙卷风
其中用户年龄是: 26
