java应用程序中发送URL中带参数的请求

param 为aaa=111&bbb=222.....格式 

import java.io.*; 
import java.net.*;
public class TestGetPost{ 

//发送带参数的GET请求
   public static String sendGet(String url,String param) {
     String result = "";
     try{
          String urlName = url + "?"+param;
          URL U = new URL(urlName);
          URLConnection connection = U.openConnection();

          connection.connect(); 

BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream())); String line; while ((line = in.readLine())!= null) { result += line; } in.close(); }catch(Exception e){ System.out.println("没有结果！"+e); } return result; } //发送带参数的Post请求
public static String sendPost(String url,String param){ String result=""; try{ URL httpurl = new URL(url); HttpURLConnection httpConn = (HttpURLConnection)httpurl.openConnection(); httpConn.setDoOutput(true); httpConn.setDoInput(true); PrintWriter out = new PrintWriter(httpConn.getOutputStream()); out.print(param); out.flush(); out.close(); BufferedReader in = new BufferedReader(new InputStreamReader(httpConn.getInputStream())); String line; while ((line = in.readLine())!= null) { result += line; } in.close(); }catch(Exception e){ System.out.println("没有结果！"+e); } return result; }
//测试 public static void main(String args[]){ // String s=TestGetPost.sendGet("","id=960"); // System.out.println(s); String s1=TestGetPost.sendPost("","type_id=1&start=50&thRange=50"); System.out.println(s1); } }
