Python 图片转 base64

base64 是一种用于传输 8Bit 字节码的编码方式，基于 64 个可打印字符来表示二进制数据

1.jpg

图片转base64

读取图片二进制数据，用 base64 加密（结果仍是 bytes 类型），保存

import base64

encoded = base64.b64encode(open('1.jpg', 'rb').read())
print(encoded)
open('1.txt', 'wb').write(encoded)  # 保存

base64转图片

import base64

decoded = base64.b64decode(open('1.txt', 'rb').read())
open('2.jpg', 'wb').write(decoded)  # 保存

图片转base64字符串

import base64

encoded = base64.b64encode(open('1.jpg', 'rb').read())
print(encoded.decode())
