BASE64编码解码
import base64
# base64是一个专门用于处理网络传输数据格式的算法，网络中传输的二进制数据是不能直接被打印或提取的，所以一般都是转换成base64编码进行数据传输。
# 把二进制数据（0~1）经过base64算法形成base64编码
# base64编码主要是 64个字符组成：[0-9A-Za-z+/]
# python内置了base64模块，提供了2个方法给我们对二进制数据进行编码与解码
# 编码
with open("1.jpeg", "rb") as f:
code = base64.b64encode(f.read()).decode()
print(f"data:image/jpeg;base64,{code}")
# 解码
