Python base64与图片之间的转换

图片转base64

#image转base64
import base64
with open("C:\\Users\\wonai\\Desktop\\1.jpg","rb") as f:#转为二进制格式
    base64_data = base64.b64encode(f.read())#使用base64进行加密
    print(base64_data)
    file=open('1.txt','wt')#写成文本格式
    file.write(base64_data)
    file.close()

注:如果使用读取txt文件内容的方法时,记得要将这之前的删掉【data:image/png;base64,】
