python将图片转base64,实现前端显示

# -*- coding: utf-8 -*-
 
import base64
 
with open("C:\\Users\\user\\Desktop\\20170508134213.png","rb") as f:
  # b64encode是编码，b64decode是解码
  base64_data = base64.b64encode(f.read())
  # base64.b64decode(base64data)
  print(base64_data)

<img src="data:image/jpg;base64,这里是base64的编码"/>
