java URL实现调用其他系统发送报文并获取返回数据
模拟本系统通过Url方式发送报文到目标服务器，并获取返回数据：（实现类）
1 import java.io.BufferedOutputStream; 2 import java.io.BufferedReader; 3 import java.io.InputStream; 4 import java.io.InputStreamReader; 5 import java.io.OutputStream; 6 import java.io.OutputStreamWriter; 7 import java.net.URL; 8 import java.net.URLConnection; 9 10 public class BlazeSao { 11 12 public static void callBlaze(String url ,String data) throws Exception{ 13 URL u = new URL(url); 14 System.out.println("建立链接...."); 15 //获取连接对象 16 URLConnection uc = u.openConnection(); 17 uc.setDoOutput(true); 18 //获取输出流对象 19 OutputStream raw = uc.getOutputStream(); 20 OutputStream buffered = new BufferedOutputStream(raw); 21 OutputStreamWriter out = new OutputStreamWriter(buffered, "UTF-8"); 22 23 System.out.println("发送报文:"+data); 24 out.write(data); 25 26 out.flush(); 27 System.out.println("关闭连接"); 28 out.close(); 29 //获取到返回数据的输入流 30 InputStream is = uc.getInputStream(); 31 BufferedReader br = new BufferedReader(new InputStreamReader(is,"UTF-8")); 32 String line = ""; 33 StringBuffer blzRspXml = new StringBuffer(); 34 System.out.println("获取返回数据:"); 35 while((line = br.readLine()) != null){ 36 //读取返回数据，分行读取 37 System.out.println(line.trim()); 38 blzRspXml.append(line.trim()); 39 } 40 } 41 42 public static void main(String args[]){ 43 44 //目标服务器地址 45 String url1 = "http://10.14.30.242:9080/RES/Rule"; 46 //发送的报文 47 String data1 = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><CardRequest><SEQ_TIME_STAMP>2014325170152799504</SEQ_TIME_STAMP><TYPE>1</TYPE><v_101>-999998</v_101><v_102>0.002740</v_102><v_109>111.11</v_109></CardRequest>"; 48 try { 49 BlazeSao.callBlaze(url1,data1); 50 } catch (Exception e) { 51 e.printStackTrace(); 52 } 53 } 54 55 }
输出日志：
