java 中http请求为了防止乱码解决方案

今天做一个与地图有关的项目，需要发起http请求地图数据

写了一个工具类，希望大家都能用上吧

package com.lrdd.utils;


import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.URL;
import java.net.URLConnection;
import java.util.List;
import java.util.Map;

public class HttpRequest {
  
  public static String sendGet(String url, String param) {
    String result = "";
    BufferedReader in = null;
    try {
      String urlNameString = url + "?" + param;
      URL realUrl = new URL(urlNameString);
      // 打开和URL之间的连接
      URLConnection connection = realUrl.openConnection();
      // 设置通用的请求属性
      connection.setRequestProperty("accept", "*
  public static String sendPost(String url, String param) {
    PrintWriter out = null;
    BufferedReader in = null;
    String result = "";
    try {
      URL realUrl = new URL(url);
      // 打开和URL之间的连接
      URLConnection conn = realUrl.openConnection();
      // 设置通用的请求属性
      conn.setRequestProperty("accept", "*/*");
      conn.setRequestProperty("connection", "Keep-Alive");
      conn.setRequestProperty("user-agent",
   "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
      // 发送POST请求必须设置如下两行
      conn.setDoOutput(true);
      conn.setDoInput(true);
      // 获取URLConnection对象对应的输出流
      out = new PrintWriter(new OutputStreamWriter(conn.getOutputStream(),"utf-8"));
      // 发送请求参数
      out.print(param);
      // flush输出流的缓冲
      out.flush();
      // 定义BufferedReader输入流来读取URL的响应
      in = new BufferedReader(
   new InputStreamReader(conn.getInputStream(),"utf-8"));
      String line;
      while ((line = in.readLine()) != null) {
 result += line;
      }
    } catch (Exception e) {
      System.out.println("发送 POST 请求出现异常！"+e);
      e.printStackTrace();
    }
    //使用finally块来关闭输出流、输入流
    finally{
      try{
 if(out!=null){
   out.close();
 }
 if(in!=null){
   in.close();
 }
      }
      catch(IOException ex){
 ex.printStackTrace();
      }
    }
    return result;
  }  
}
