對應調用端的Java代碼（只是個demo，參數都暫時寫死了）如下：

import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import java.net.MalformedURLException;import java.net.URL;import java.net.URLConnection;public class HttpPostTest {    void testPost(String urlStr) {        try {            URL url = new URL(urlStr);            URLConnection con = url.openConnection();            con.setDoOutput(true);            con.setRequestProperty("Pragma:", "no-cache");            con.setRequestProperty("Cache-Control", "no-cache");            con.setRequestProperty("Content-Type", "text/xml");            OutputStreamWriter out = new OutputStreamWriter(con                    .getOutputStream());                String xmlInfo = getXmlInfo();            System.out.println("urlStr=" + urlStr);            System.out.println("xmlInfo=" + xmlInfo);            out.write(new String(xmlInfo.getBytes("ISO-8859-1")));            out.flush();            out.close();            BufferedReader br = new BufferedReader(new InputStreamReader(con                    .getInputStream()));            String line = "";            for (line = br.readLine(); line != null; line = br.readLine()) {                System.out.println(line);            }        } catch (MalformedURLException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        }    }    private String getXmlInfo() {        StringBuilder sb = new StringBuilder();        sb.append("<videoSend>");        sb.append("    <header>");        sb.append("        <sid>1</sid>");        sb.append("        <type>service</type>");        sb.append("    </header>");        sb.append("    <service name=\"videoSend\">");        sb.append("        <fromNum>0000021000011001</fromNum>");        sb.append("           <toNum>33647405</toNum>");        sb.append("        <videoPath>mnt/5.0.217.50/resources/80009.mov</videoPath>");        sb.append("        <chargeNumber>0000021000011001</chargeNumber>");        sb.append("    </service>");        sb.append("</videoSend>");        return sb.toString();    }    public static void main(String[] args) {        String url = "http://5.0.217.50:17001/VideoSend";        new HttpPostTest().testPost(url);    }}

2 XML傳輸

二、用戶端代碼

通過Http Post Xml傳遞資料，用戶端一般是通過URL建立到服務端的串連，向服務端發送xml資料，然後擷取服務端的響應並進行解析：
