Base64编码的Java连接code和德code字符串

本文介绍了Base64编码的Java连接code和德code字符串的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我要带code字符串转换成Base64和通过套接字和DE code将其传送回来。但解码之后它给了不同的答案。以下是我的code和结果为77 + 9x6s =

I want to encode a string into base64 and transfer it through a socket and decode it back. But after decoding it gives different answer. Following is my code and result is "77+9x6s="

import javax.xml.bind.DatatypeConverter;

    public class f{

       public static void main(String a[]){

          String str = new String(DatatypeConverter.parseBase64Binary("user:123"));
          String res = DatatypeConverter.printBase64Binary(str.getBytes());
          System.out.println(res);
       }
    }

有关如何实现这个任何想法？

Any idea about how to implement this?

推荐答案

您可以用下面的办法，

// encode data on your side using BASE64
byte[]   bytesEncoded = Base64.encodeBase64(str .getBytes());
System.out.println("ecncoded value is " + new String(bytesEncoded ));

// Decode data on other side, by processing encoded data
byte[] valueDecoded= Base64.decodeBase64(bytesEncoded );
System.out.println("Decoded value is " + new String(valueDecoded));

希望这回答了你的疑问。

Hope this answers your doubt.
