场景一：

package com.guonian.miaosha;

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

public class Test {
    public static void main(String[] args) throws IOException {
        URL url = new URL("http://192.168.1.220:8080/file/%FL%AC%94%E8%BA%.txt");
        //创建接口地址对象
        HttpURLConnection connection = (HttpURLConnection)url.openConnection();
        //设置请求方式
        //connection.setRequestMethod("GET");
        connection.connect();
        BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream(),"UTF-8"));
        String line = null;
        while(null != (line = br.readLine())){
            System.out.println(line);
        }
        br.close();
    }

            // 对字节数组Base64编码
