Jsp中使用xmlhttp进行数据交互~

1.客户端提交请求
Domain = " test.com"
sxml = "<?xml version=""1.0"" encoding=""gb2312"" ?>" &_
"<Package>" &_
"<Domain>" & Domain & "</Domain>" &_
"</Package>"

http://www.gaodaima.com/41855.htmljsp中使用xmlhttp进行数据交互~

Set oD = Server.CreateObject("Microsoft.XMLHTTP")
oD.Open "Post", "http://Server/Domain_Check.jsp", False
oD.Send(sXml)

If oD.Status = 200 Then
Result = oD.responseText
Set o = Server.CreateObject("Microsoft.XMLDOM")
o.LoadXML(Result)

Domain = CInt(o.selectSingleNode("//Result").text)
Response.Write Domain
Set o = Nothing
Set oD = Nothing
End If

2.服务器端解析数据包
<%@ page import="java.util.*" %>
<%@ page import="java.text.*" %>
<%@ page import="java.io.*" %>
<%@ page import="org.w3c.dom.*" %>
<%@ page import="javax.xml.parsers.*" %>
<%@ page contentType="text/html; charset=gbk" %>
<%
//获得数据包
request.setCharacterEncoding("UTF-8");
BufferedReader in = request.getReader();
String line;
String xmlRequest = "";
String domain_name = "";

while ((line = in.readLine()) != null)
{
//构造数据包
xmlRequest = xmlRequest + line + "/n";
}
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder db = factory.newDocumentBuilder();
ByteArrayInputStream stream = new ByteArrayInputStream(xmlRequest.getBytes("UTF-8"));
Document doc = db.parse(stream);
Element root = doc.getDocumentElement();

NodeList Domain = root.getElementsByTagName("Domain");
if (Domain.getLength() == 1) {
Element e = (Element) Domain.item(0);
domain_name = (String) e.getFirstChild().getNodeValue();
}
//返回数据
out.println("<?xml version=/"1.0/" encoding=/"gb2312/" ?>/n");
out.println("<Package>/n");
out.println("/t<Result>" + domain_name + "</Result>/n");
out.println("</Package>");
%>

3.得到返回结果
test.com
