我们在编写ASP代码的时候,大家都知道可以通过post或者get获得form表单的数据,那么我们如何直接获得其他页面上的数据呢?这就要借助xmlhttp协议了。xmlhttp是xmldom技术的一部分。
下面的代码就是一个很简单的例子,我们利用xmlhttp技术,把http://www.codetoad.com/站点首页的代码以xml的形式完全获取,并且在页面中输出。
<%
Dim objXMLHTTP, xml
Set xml = Server.CreateObject("Microsoft.XMLHTTP")
xml.Open "GET", "http://www.codetoad.com/", False
' Pull the data from the web page
xml.Send
Response.write "Here's the html we now have in our xml object"
Response.write "<BR<BR<BR"
Response.Write "<xmp"
Response.Write xml.responseText
Response.Write "</xmp"
Response.write "<BR<BR<BR"
Response.write " Now here's how the page looks:<BR<BR"
Response.Write xml.responseText
Set xml = Nothing
%
下面是另一个实例
<%
dim objHTTP , objXML , objXSL
set objHTTP = Server.CreateObject("Microsoft.XMLHTTP")
objHTTP.open "GET", "http://p.moreover.com/cgi-local/page?c=Pop%20music%20reviews&o=xml", false
objHTTP.send
set objXML = objHTTP.responseXML
set objXSL=Server.CreateObject("microsoft.xmldom")
objXSL.async=false
objXSL.load(Server.MapPath("style.xsl"))
if (objXSL.parseError.errorCode = 0) then
Response.Write(objXML.transformnode(objXSL))
else
Response.Write "Error: " & objXSL.parseError.reason & " URL:" & objXSL.url
end if
Set objHTTP = Nothing
Set objXML = Nothing
Set objXSL = Nothing
