我的代码:

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

x\x9cK).. 

a='dsss' 
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 

请您参考如下方法:

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。
