推荐答案

不必为此制作定制的中间件。

It's not necessary to make a custom middleware for this.

设置 SESSION_SAVE_EVERY_REQUEST = True 将导致Django现有的 SessionMiddleware 完全按照您的要求进行操作

Setting SESSION_SAVE_EVERY_REQUEST = True will cause Django's existing SessionMiddleware to do exactly what you want.

它具有以下代码：

if modified or settings.SESSION_SAVE_EVERY_REQUEST:
    if request.session.get_expire_at_browser_close():
        max_age = None
        expires = None
    else:
        max_age = request.session.get_expiry_age()
        expires_time = time.time() + max_age
        expires = cookie_date(expires_time)
    # Save the session data and refresh the client cookie.
    # Skip session save for 500 responses, refs #3881.
    if response.status_code != 500:
        request.session.save()
        response.set_cookie(settings.SESSION_COOKIE_NAME,
                request.session.session_key, max_age=max_age,
                expires=expires, domain=settings.SESSION_COOKIE_DOMAIN,
                path=settings.SESSION_COOKIE_PATH,
                secure=settings.SESSION_COOKIE_SECURE or None,
                httponly=settings.SESSION_COOKIE_HTTPONLY or None)
