(1)在java早期使用JDK里sun.misc套件下的BASE64Encoder和BASE64Decoder这两个类别,主要代码如下 final BASE64Encoder encoder =new BASE64Encoder(); final BASE64Decoder decoder =new BASE64Decoder(); final String text ="字串文字"; finalbyte[] textByte = text.getBytes("UTF-8"); //编码 final Strin...
BASE64Decoder decoder = new BASE64Decoder(); byte[] bytes = decoder.decodeBuffer(imagestr); 替换成如下方法即可 import java.util.Base64.Encoder; import java.util.Base64.Decoder; //加解密的包 Encoder encoder = Base64.getEncoder();

BASE64Decoderdecoder=newBASE64Decoder(); 1. 3. 定义Base64编码字符串 在解码之前,我们需要定义一个Base64编码的字符串,用于演示解码过程。这个编码字符串可以是任何字符串,但必须是经过Base64编码的。例如,我们可以定义一个Base64编码的字符串cGFzc3dvcmQ=,它表示的是字符串 “password” 的Base64编码结果。代...
