【图】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"
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("Packagen");
out.println("tResult" + domain_name + "/Resultn");
out.println("/Package");
