Java 中进行base64 编码和解码

import org.apache.commons.codec.binary.Base64;


public class Base64Demo {

	public static void main(String[] args) {
		
		
		String str = "{\"Bucket\":\"doc\",\"Object\":\"anne.jpg\",\"Expires\":1451491200}";
		String baseencode = new String(Base64.encodeBase64(str.toString().getBytes()));
		System.out.println(baseencode);//编码得到 eyJCdWNrZXQiOiJkb2MiLCJPYmplY3QiOiJhbm5lLmpwZyIsIkV4cGlyZXMiOjE0NTE0OTEyMDB9
		String basedecode = new String(Base64.decodeBase64(baseencode.toString().getBytes()));
		System.out.println(basedecode);//解码后得到{"Bucket":"doc","Object":"anne.jpg","Expires":1451491200}
		

	}

}
