使用Base64.decode64（'在这里插入上面的二进制数据'）返回以下乱码

我需要将它解码为这样的浮点数列表 27489.1602 57338.4453 45343.3516 91321.0391 43205.043 等等....
感谢您的帮助！
答案 0 :(得分：1)
您可以使用s.unpack('m*')[0]解码Base64字符串。
它与：Base64.decode64(s)
现在我们有一个我们想要#unpack的字符串，将位序列转换为新对象。
比特序列保存1368个字节（一旦Base64被解码），其中包含171个64位序列......我想也许这就是你要找的：
s.unpack('m*')[0].unpack('d*')
# => [595.6329345703125, 596.281005859375, 596.529296875, ... ]
...只是我没有在你的例子中得到这些值，所以我一定是错的。
