Question

我从远程数据库中拉出base64编码的图像字符串并尝试使用base64.decode（）解码它，但输出图像是损坏的（图像大小只有几个字节甚至0个字节）代码是：

import pymssql
import base64
import os

con=pymssql.connect(user='**',
                    password='**',
                    database='**',
                    host='**')

cur=con.cursor()
cur.execute("SELECT PHOTOGRAPH_IMG FROM IHHL_DETAIL_IMG WHERE APPLICATION_ID='**';")
result=cur.fetchall()  #tried fetchone() too
result=list(result)    #to save the tuple returned as a list
print result[0]        

cur.close()
con.close()

#I've tried various formats to decode, none work 
#fh=open("img.jpeg","wb")
#fh.write(result[0].decode('base64'))
with open("imageToSave.png", "wb") as fh:
fh.write(base64.decode(result[0]))
fh.close()

只需将其添加为“代码”

即可

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

将base64编码图像解码为python中的orignal图像
