Question

我有一个.py脚本，它将base64文件保存到png文件

# SAVE BASE64 STRING TO PNG IMAGE
timestr = time.strftime("%Y%m%d%H%M%S")
filename = "/user_score/"+self.user.username+timestr+".png"
saved_file = MEDIA_ROOT+"/"+filename
fh = open(saved_file, "wb")
fh.write(imgbase64.decode('base64'))
fh.close()

这是通过AJAX函数调用到这样的URL
