Python实现图片的base64编码

import base64

if __name__ == "__main__":
    dir='image.jpg'

    basef=open(dir.split('.')[0]+'_base64.txt','w') 
    with open (dir,'rb') as f:
        base64_data=base64.b64encode(f.read())
        s=base64_data.decode()
        data='data:image/jpeg;base64,%s'%s
        # print(data)
        basef.write(data)
    
    basef.close()
