我调试了它,并将其写入磁盘,但是当我打开它显示错误说:

#!/usr/bin/python import MySQLdb db2 = MySQLdb.connect(host="localhost", user="root", passwd="root", db="digit") cur = db2.cursor() #get the name of the file cur.execute("SELECT Name FROM ContentFiles WHERE ID=3") nombre = cur.fetchone() #open file and write into. with open(nombre[0],"wb") as output_file: cur.execute("SELECT File FROM ContentFiles WHERE ID=3") ablob = cur.fetchone() output_file.write(ablob[0])

Any help would be appreciated. Thanks :)

archivo = cur.fetchone()

imagen = open(archivo[2],'wb')
imagen.write(archivo[1].decode('base64'))
imagen.close()
