为什么会这样？

这是因为在第二个字符串的末尾有额外的

“\n”

。如果运行以下命令，可以很容易地看到：

echo "your base 64 encoded string"|base64 -d|hexdump -C

---

在linux shell中

感谢您的编辑！！！不客气：-）@Mudit@Mudit你说“对”是什么意思？对于两个不同的字符串，这两个字符串都是右基64编码的表示形式-第一个字符串末尾没有

eol

，第二个字符串末尾有

eol

。@Mudit，显然，在线编码器在转换之前会将

\n

序列添加到字符串中。所以我认为对于你们的程序来说，第一个字符串是“对的”。

echo "your base 64 encoded string"|base64 -d|hexdump -C
