我的代码:

import zlib
print 'dsss'.decode('base64').decode('zlib')#error

Traceback (most recent call last):
  File "D:\zjm_code\b.py", line 4, in <module>
    print 'dsss'.decode('base64').decode('zlib')

a=a.encode('zlib')
#print a
a=a.decode('zlib')
print a#its ok

我认为“打印 a”用“uhf-8”编码 a。所以:

#encoding:utf-8
a='dsss'
a=a.encode('zlib')
print a
a=a.decode('utf-8')#but error.
a=a.decode('zlib')
print a#

    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0x9c in position 1: unexpected code byte

Answer 1

字符串中的数据是经过编码和压缩的二进制数据。 .decode("base64").decode("zlib") 取消编码并解压缩它。

您收到的错误是因为从 base64 解码的“dsss”不是有效的 zlib 压缩数据。
