http远程调用原生get、post模板

一、get方法

 package lq.httpclient.method;

 import java.io.BufferedReader;
 import java.io.IOException;
 import java.io.InputStreamReader;
 import java.net.HttpURLConnection;
 import java.net.MalformedURLException;
 import java.net.URL;

 import org.junit.Test;

 public class HttpGet {

     @Test
     public void test() {
         String url = "http://127.0.0.1:8080/ccb-cloud";
         try {
             URL targetUrl = new URL(url);
             HttpURLConnection connection = (HttpURLConnection)targetUrl.openConnection();
             connection.setRequestMethod("GET");
             connection.setRequestProperty("Accept", "application/json");
             if(connection.getResponseCode() != 200) {
                 throw new RuntimeException(""+connection.getResponseCode());
             }
             BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
             String outPut;
             while((outPut = bufferedReader.readLine()) != null) {
                 System.out.println(outPut);
             }
         } catch (MalformedURLException e) {
             e.printStackTrace();
         } catch (IOException e) {
             e.printStackTrace();
         }
     }
 }

二、post方法

 package lq.httpclient.method;

 import java.io.BufferedReader;
 import java.io.IOException;
 import java.io.InputStreamReader;
 import java.io.OutputStream;
 import java.net.HttpURLConnection;
 import java.net.MalformedURLException;
 import java.net.URL;

 import org.junit.Test;

 import com.alibaba.fastjson.JSONObject;

 public class HttpPost {

     @Test
     public void test() {
         String url = "http://127.0.0.1:8080/ccb-cloud";
         try {
             URL targetUrl = new URL(url);
             HttpURLConnection connection = (HttpURLConnection)targetUrl.openConnection();
             connection.setRequestMethod("POST");
             connection.setRequestProperty("Content-Type", "application/json");
             //允许输入参数
             connection.setDoOutput(true);
             JSONObject jsonObject = new JSONObject();
             jsonObject.put("name", "zhangsan");
             byte[] bytes = jsonObject.toString().getBytes();
             //超时20S
             connection.setConnectTimeout(20000);
             OutputStream outStream = connection.getOutputStream();
             outStream.write(bytes);
             outStream.flush();
             outStream.close();
             if(connection.getResponseCode() != 200) {
                 throw new RuntimeException(""+connection.getResponseCode());
             }
             BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
             String outPut;
             while((outPut = bufferedReader.readLine()) != null) {
                 System.out.println(outPut);
             }
         } catch (MalformedURLException e) {
             e.printStackTrace();
         } catch (IOException e) {
             e.printStackTrace();
         }finally {
             System.out.println("ends");
         }
     }
 }
