1、直接显示已存储的图片：
from PIL import Image
im = Image.open(r'e:\p1.jpeg' )
im.show()
2、python存储redis图片：
db = redis.Redis(host='127.0.0.1', port= 6379, password= '********', db= 0,decode_responses=True,charset='UTF-8',encoding='UTF-8')
with open(r'e:\p1.jpeg','rb') as f:
base64_data = base64.b64encode(f.read())
# print(base64_data)
db.set('user_img',base64_data)
3 pyhton获取redis图片：
img_base64 = db.get('user_img')
data = base64.b64decode(img_base64)
4 显示图片：在软件内显示
import redis
import io
import base64
from PIL import Image
import matplotlib.pyplot as plt
image = Image.open(io.BytesIO(data))
plt.imshow(image)
plt.show()
5 也可以这样显示：在IE上显示
from PIL import Image
image = Image.open(io.BytesIO(data))
image.show()
