导 读： 在这里用到了好几个类：WebRequestFactory、HttpWebRequest、HTTPWEBRESPONSE 和 STREAMREADER。前三个用来建立一个HTTP连接，然后通过此连接建立一个STREAMREADER对象，最后将得到的数据赋值给一个字符变量，在页面上显示。
该文中几个类的使用是值得注意的地方。
豆腐在以前的文章中 讲过 如何用 PHp 和 Asp 跨站抓取别的站点的页面，今天我们来测试一下 asp+
是怎么实现 跨站抓取 别的站点的页面
Code Listing
<%@ Assembly Name="System.Net" %>
<%@ Import Namespace="System.Net" %>
<%@ Import Namespace="System.IO" %>
<script language="VB" runat="server">
Sub Page_Load(Src As Object, E As EventArgs)
Dim HttpWResp as HTTPWebresponse
Dim sr As StreamReader
dim STRtemp as string
text1.text = ""
HttpWReq = WebRequestFactory.Create("")
HttpWReq.KeepAlive = false
HttpWResp = HttpWReq.GetResponse()
sr = new StreamReader(HttpWResp.GetResponseStream(), Encoding.ASCII)
Try
line=sr.ReadLine()
do while line <> null
line = sr.ReadLine()
lineENC = server.HTMLencode(line) & vbcrlf & "
"
text1.text = text1.text & lineENC
loop
Catch ex As Exception
text1.text = "发生错误: " & ex.Message
End Try
End Sub
</script>
<html><head>
<title>跨站</title>
</head>
<body bgcolor="#FFFFFF">
<h3><font face="Verdana">抓来得数据</font></h3>
<asp:TextBox id="text1" Width="600px" Textmode="multiline" rows="40"
runat="server"/>
</body></html>
