If an optional attribute is not set on the cookie it's value is None. domain Restrict cookie usage to this domain path Restrict cookie usage to this path or below expires Cookie is invalid after this UTC timestamp max_age Cookie is invalid this many seconds in the future. Has precedence over the expires attribute. secure Cookie should only be returned on secure (i.e. SSL/TLS) connections. httponly Cookie is intended only for HTTP communication, it can never be utilized in any other context (e.g. browser Javascript). See the documentation of get_expiration() for an explanation of how the expires and max-age attributes interact as well as the role of the timestamp attribute. Expiration values are stored as datetime objects for easy manipulation and comparision. There are two ways to instantiate a Cookie object. Either directly via the constructor or by calling the class function parse() which returns a list of Cookie objects found in a string. To create a cookie to sent to a client: Example: cookie = Cookie('session', session_id, domain=my_domain, path=mypath, httponly=True, secure=True, expires=expiration) headers.append(('Set-Cookie', str(cookie))) To receive cookies from a request: Example: cookies = Cookie.parse(response.getheader('Set-Cookie'), request_url) c @ s e Zd ZdS )zCookie.ExpiredN��__name__� __module__� __qualname__� r r �4/usr/lib/python3.9/site-packages/ipapython/cookie.py�Expired| s r c @ s e Zd ZdS )zCookie.URLMismatchNr r r r r � URLMismatch s r z;\s*z@^\s*([a-zA-Z0-9\!\#\$\%\&\'\*\+\-\.\^\_\`\|\~]+)\s*=\s*(.*?)\s*$�domain�path�max_age�expires�secure�httponly)r r zmax-ager r r c C s t |�� �S )ag Timestamps (timestamp & expires) are stored as datetime objects in UTC.

This is basically a utility wrapper around the parse() class method which iterates over what parse() returns looking for the specific cookie. When cookie_name appears more than once the last instance is returned rather than the first because the ordering sequence makes the last instance the current value.

The expiration will be timestamp + max_age. The timestamp value will aways be a datetime object. By default the timestamp will be the moment the Cookie object is created as this often corresponds to the moment the cookie is received (the intent of the Max-Age attribute). But becuase it's sometimes desirable to force a specific moment for purposes of computing the expiration from the Max-Age the Cookie timestamp can be updated. Setting a value of None causes the timestamp to be set to the current UTC time (now). You may also assign with a numeric UNIX timestamp (seconds since the epoch UTC) or a formatted time sting, in all cases the value will be converted to a datetime object. )� _timestamp�rA r r r r> l s zCookie.timestampc C sn |d u rd | _ nZt|tj�r$|| _ nFt|ttf�rBt|dd�| _ n(t|t�rZt�|�| _ nt d|j j ��d S )Nr" �Zunits�Dvalue must be datetime, int, long, float, basestring or None, not %s) rC � isinstance�datetime�int�floatr �strr r � TypeError� __class__r �rA r< r r r r> � s �c C s | j S )aH The expiration timestamp (in UTC) as a datetime object for the cookie, or None if not set.

Expiration may be defined either by the "Expires" timestamp attribute or the "Max-Age" duration attribute. If both are set "Max-Age" takes precedence. If neither is set the cookie has no expiration and None will be returned. "Max-Age" specifies the number of seconds in the future from when the cookie is received until it expires. Effectively it means adding "Max-Age" seconds to a timestamp to arrive at an expiration. By default the timestamp used to mark the arrival of the cookie is set to the moment the cookie object is created. However sometimes it is desirable to adjust the received timestamp to something other than the moment of object creation, therefore you can explicitly set the arrival timestamp used in the "Max-Age" calculation. "Expires" specifies an explicit timestamp. If "Max-Age" is set a datetime object is returned which is the sum of the arrival timestamp and "Max-Age". If "Expires" is set a datetime object is returned matching the timestamp specified as the "Expires" value. If neither is set None is returned.

The "Max-Age" attribute has precedence over "Expires" if both are specified. This method normalizes the expiration of the cookie such that only a "Expires" attribute remains after consideration of the "Max-Age" attribute. This is useful when storing the cookie for future reference.
