在python中將base64編碼的圖像解碼為原始圖像

Question

我從遠程數據庫中提取了一個base64編碼的圖像字符串，並嘗試使用base64.decode（）對其進行解碼，但是輸出圖像是損壞的圖像（圖像大小僅為幾個字節甚至0字節），代碼為：

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()

Answer 1

只需將其添加為“代碼”

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
