需求：

有时候，图片需要储存到数据库时，可以进行base64，进行先转换再进行保存到数据库，然后取出来时在使用base64，解码转换：

base64与图片互转

直接上代码，需要的可以参考。

import base64


# 图片转base64
def from_photo_to_base64(path):
    with open(path, "rb") as file_photo:  # 转为二进制格式
        ret = file_photo.read()
    base64_data = base64.b64encode(ret)  # 使用base64进行加密
    print(base64_data)
    with open('base64.txt', 'w', encoding='utf-8') as file_w_base64:  # 写成文本格式
        file_w_base64.write(base64_data.decode('utf-8'))


# base64转图片
def from_base64_to_photo(path):
    with open(path, "r") as file_read_base64:
        base64_str = file_read_base64.read()
    imgdata = base64.b64decode(base64_str)
    with open('美女2.jpg', 'wb') as file_w_photo:
        file_w_photo.write(imgdata)


if __name__ == '__main__':
    path = "美女.jpg"
    from_photo_to_base64(path)
    path2 = 'base64.txt'
    from_base64_to_photo(path2)
