转换为base 64时，TypeError:'str'不支持缓冲区接口 [英] when convert to base 64, TypeError: 'str' does not support the buffer interface

问题描述

im = Image.open(filePath)                     # load image
self.msg = str(bytearray(list(im.getdata()))) # convert image data to string
encodedMsg = base64.b64encode(self.msg)

当我尝试将从图像读取的数据编码为base64时，它返回错误:

when I was trying to encode the data read from an image to base64, it returns an error:

File "Steganography.py", line 42, in msgToXml
    encodedMsg = base64.b64encode(self.msg)
  File "/opt/python3/current/lib/python3.4/base64.py", line 62, in b64encode
    encoded = binascii.b2a_base64(s)[:-1]
TypeError: 'str' does not support the buffer interface

当我在家使用Ubuntu(python 2.7)时，它可以工作.但是当我使用学校机器(python3.4)时，它显示错误.我该如何解决?

It works when I'm home using Ubuntu(python 2.7). But it shows error when I use school machine(python3.4). How can I solve this?

推荐答案

encodedMsg = base64.b64encode(self.msg.encode('ascii'))

参考: Python 3中的Base64编码
