今天在给平台用户提供http简单接口的时候，顺便写了个调用的Java类供他参考。
     服务器地址：http://5.0.217.50:17001/VideoSend

服务器提供的是xml格式的http接口，接口定义如下：

<!--视频点送: videoSend-->
<videoSend>
    <header>
        <sid>%s</sid> 
        <type>service</type> 
    </header>
    <service name="videoSend">
    <fromNum>%s</fromNum>     
    <toNum>%s</toNum>                   <!--需要接通的用户的电话号码 -->
    <videoPath>%s</videoPath>           <!--视频文件路径 -->
    <chargeNumber>%s</chargeNumber>     <!--计费号码 -->
    </service>
</videoSend>


<!--视频点送返回结果: videoSendResult-->
<videoSend>
    <header>
    <sid>%s</sid> 
    <type>service</type> 
    </header>
    <service name="videoSendResult">
    rescode>%s</rescode>                 <!--0000:视频点送成功，0001:请求参数信息错误, 0002:接通用户失败-->
    </service>
</videoSend>

对应调用端的Java代码（只是个demo，参数都暂时写死了）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);
    }
}
