MIME BASE64编码与解码 （java实现）

说明： 涉及的jar包： commons-codec-1.2.jar

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

public class Base64Test {

public static void main(String[] args) {

String str = "1tC5+g==";

byte[] enStr;

try {

//============ encode by base64 with gb2312 ===============

enStr = Base64.encodeBase64(str.getBytes("GB2312"));

String enCode = new String(enStr,"utf-8");

System.out.println(enCode);



//============ decode by base64 with gb2312 ===============

byte[] deCode = Base64.decodeBase64(str.getBytes("utf-8"));

System.out.println(new String(deCode,"GB2312"));

} catch (Exception e) {

e.printStackTrace();

}

}

}
