如何在python中对64位二进制文​​件进行base64编码/解码? [英] How to base64 encode/decode binary files in python?

问题描述

我正在尝试使用以下简单代码使用python对相同的图像文件进行编码和解码.但是每次输出文件都大于输入文件，并且无法打开.这段代码有什么问题?

I'm trying to encode and decode the same image file using python using following simple code. But every time output file is larger than input file and it can't open. What's the problem in this code?

import base64

with open("img.jpeg", "rb") as image_file:
    encoded_string = base64.b64encode(image_file.read())

    decoded_string = base64.b64decode(encoded_string)
    with open("test_img.jpeg", "w") as image_file2:
        image_file2.write(decoded_string);

推荐答案

尝试将写入模式更改为"wb" .您现在的写作和阅读都采用了不同的格式.

Try changing the write mode to "wb". Your writing and reading as different formats right now.
