[网络协议]java读取url地址文件为String或者byte

文本文件适合读取为String，图片视频等特殊文件适合读取为byte

    private static final String URL = "";
       
    public static void main(String[] args) {
        try {
            //直接读取为byte
            java.net.URL url = new URL(URL);
            byte [] bytes = IOUtils.toByteArray(url.openStream());
//            String s1 = new String(bytes);
//            System.out.println(s1);
            //读取为String
            BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream()));
            String s2;
            while ((s2 = reader.readLine()) != null) {
                System.out.println(s2);
            }
            reader.close();
        }catch (IOException e){
            System.out.println("ee");
        }

    }
