接口通信的方式(上 )http方式

发送请求

String post_url = "http://10.1.3.121:9002/Mbomc/servlet/ControlSer;

URL url = null;
HttpURLConnection connection = null;
OutputStreamWriter outWriter = null;
url = new URL(post_url);
connection = (HttpURLConnection) url.openConnection();

connection.setDoInput(true);// 必须设置成TRUE
connection.setDoOutput(true);// 必须设置成true
connection.setRequestProperty("Content-Type", "text/xml");// 这个不能少
connection.setRequestMethod("POST"); 
connection.setConnectTimeout(5000); 
connection.setReadTimeout(5000); 
connection.connect();

BufferedWriter out = new BufferedWriter(new OutputStreamWriter(
httpURLConnection.getOutputStream(), "GBK"));

outWriter = new OutputStreamWriter(connection.getOutputStream(),
"GBK");
outWriter.write(xml);
outWriter.flush();
outWriter.close();

接收请求　　

BufferedReader reader = null;
reader = new BufferedReader(new InputStreamReader(request
					.getInputStream(), "GBK"));
String readXml;
	while ((readXml = reader.readLine()) != null) {
		System.out.println("读取XML" + readXml);
	}
reader.close();
