python | 浅学 | 6 LookupError: 'base64' is not a text encoding; use codecs.encode() to handle arbitrary codecs

 你这样

import base64
str1 = "this is string example"
print (str1)
str1 = str1.encode(encoding ='utf-8',errors = 'strict') # 先转成bytes 的string
print (str1)
str2= base64.b64encode(str1)                            # 再使用base64.b64encode
print (str2)
enstr =base64.b64decode(str2)                           # 解密  base64.b64decode
print(enstr)
enstr =enstr.decode()
print(enstr)

 

输入结果：
