Plus front uuid utilizes graphical verification code to verify, codes generally have a expiration time. Let's set an expiration time.
def Image_code(request, img_id):
text, image = captcha.generate_captcha()
# 配置数据库连接
redis_conn = get_redis_connection('verify_code')

# 设置过期时间
request.session['image_code'] = text
request.session.set_expiry(60)

To mention a way to cache the session redis inside.
