java URL實現調用其他系統發送報文並獲取返回數據

 

    模擬本系統通過Url方式發送報文到目標服務器，並獲取返回數據：（實現類）

import java.io.BufferedOutputStream;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.URL;
import java.net.URLConnection;

public class BlazeSao {

    public static void callBlaze(String url ,String data) throws Exception{
        URL u = new URL(url);
        System.out.println("建立鏈接....");
        //獲取連接對象
        URLConnection uc = u.openConnection();
        uc.setDoOutput(true);
        //獲取輸出流對象
        OutputStream raw = uc.getOutputStream();
        OutputStream buffered = new BufferedOutputStream(raw);
        OutputStreamWriter out = new OutputStreamWriter(buffered, "UTF-8");

        System.out.println("發送報文:"+data);
        out.write(data);

        out.flush();
        System.out.println("關閉連接");
        out.close();
        //獲取到返回數據的輸入流
        InputStream is = uc.getInputStream();
        BufferedReader br = new BufferedReader(new InputStreamReader(is,"UTF-8"));
        String line = "";
        StringBuffer blzRspXml = new StringBuffer();
        System.out.println("獲取返回數據:");
        while((line = br.readLine()) != null){
            //讀取返回數據，分行讀取
            System.out.println(line.trim());
            blzRspXml.append(line.trim());
        }
    }

    public static void main(String args[]){
        
        //目標服務器地址
        String url1 = "http://10.14.30.242:9080/RES/Rule";
        //發送的報文
        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>";
        try {
            BlazeSao.callBlaze(url1,data1);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

輸出日志：
