如何解码ldap3 thumbnailPhoto以在模板中显示它？

import ldap3
import base64
from PIL import Image

# LDAP服务器配置
server = ldap3.Server('ldap://your_ldap_server')
username = 'your_username'
password = 'your_password'

# 连接到LDAP服务器
conn = ldap3.Connection(server, user=username, password=password)
conn.bind()

# 搜索LDAP目录
conn.search('ou=users,dc=example,dc=com', '(objectClass=user)', attributes=['thumbnailPhoto'])

# 获取搜索结果中的缩略图像数据
entry = conn.entries[0]
thumbnail_data = entry.thumbnailPhoto.value

# 解码缩略图像数据
decoded_data = base64.b64decode(thumbnail_data)

# 将解码后的数据保存为图像文件
with open('thumbnail.jpg', 'wb') as f:
    f.write(decoded_data)

# 在模板中显示图像
image = Image.open('thumbnail.jpg')
image.show()
