Jsp中使用xmlhttp進行資料互動~

js|xml|互動|資料 1.用戶端提交請求
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.伺服器端解析資料包
<%@ 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" %>
<%
//獲得資料包
request.setCharacterEncoding("UTF-8");
BufferedReader in = request.getReader();
String line;
String xmlRequest = "";
String domain_name = "";

while ((line = in.readLine()) != null)
{
//構造資料包
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();
}
//返回資料
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.得到返回結果
test.com
