python base64 decode incorrect padding错误解决方法

python/' target='_blank'>python的base64.decodestring方法做base64解码时报错:
复制代码 代码如下:
Traceback (most recent call last):
File "/export/www/outofmemory.cn/controllers/user.py", line 136, in decryptPassword
encryptPwd = base64.b64decode(encryptPwd)
File "/usr/lib/Python2.7/base64.py", line 76, in b64decode
raise TypeError(msg)
TypeError: Incorrect padding
这也算是python的一个坑吧,解决此问题的方法很简单,对base64解码的string补齐等号就可以了,如下代码:
复制代码 代码如下:
def decode_base64(data):
"""Decode base64, padding being optional.
:param data: Base64 data as an ASCII byte string
:returns: The decoded byte string.
"""
missing_padding = 4 - len(data) % 4
if missing_padding:
data += b'='* missing_padding
return base64.decodestring(data)
