Java发送HTTP POST请求（内容为xml格式）
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);
}
}
