Cookies
|
|
=======
|
|
|
|
Cookies are pieces of data which persist inside a user's browser. Sanic can
|
|
both read and write cookies, which are stored as key-value pairs.
|
|
|
|
.. warning::
|
|
|
|
Cookies can be freely altered by the client. Therefore you cannot just store
|
|
data such as login information in cookies as-is, as they can be freely altered
|
|
by the client. To ensure data you store in cookies is not forged or tampered
|
|
with by the client, use something like `itsdangerous`_ to cryptographically
|
|
sign the data.
|
|
|
|
|
|
Reading cookies
|
|
---------------
|
|
|
|
A user's cookies can be accessed via the ``Request`` object's ``cookies`` dictionary.
|
|
|
|
.. code-block:: python
|
|
|
|
from sanic.response import text
|
|
|
|
@app.route("/cookie")
|
|
async def test(request):
|
|
test_cookie = request.cookies.get('test')
|
|
return text("Test cookie set to: {}".format(test_cookie))
|
|
|
|
Writing cookies
|
|
---------------
|
|
|
|
When returning a response, cookies can be set on the ``Response`` object.
|
|
|
|
.. code-block:: python
|
|
|
|
from sanic.response import text
|
|
|
|
@app.route("/cookie")
|
|
async def test(request):
|
|
response = text("There's a cookie up in this response")
|
|
response.cookies['test'] = 'It worked!'
|
|
response.cookies['test']['domain'] = '.gotta-go-fast.com'
|
|
response.cookies['test']['httponly'] = True
|
|
return response
|
|
|
|
Deleting cookies
|
|
----------------
|
|
|
|
Cookies can be removed semantically or explicitly.
|
|
|
|
.. code-block:: python
|
|
|
|
from sanic.response import text
|
|
|
|
@app.route("/cookie")
|
|
async def test(request):
|
|
response = text("Time to eat some cookies muahaha")
|
|
|
|
# This cookie will be set to expire in 0 seconds
|
|
del response.cookies['kill_me']
|
|
|
|
# This cookie will self destruct in 5 seconds
|
|
response.cookies['short_life'] = 'Glad to be here'
|
|
response.cookies['short_life']['max-age'] = 5
|
|
del response.cookies['favorite_color']
|
|
|
|
# This cookie will remain unchanged
|
|
response.cookies['favorite_color'] = 'blue'
|
|
response.cookies['favorite_color'] = 'pink'
|
|
del response.cookies['favorite_color']
|
|
|
|
return response
|
|
|
|
Response cookies can be set like dictionary values and have the following
|
|
parameters available:
|
|
|
|
- ``expires`` (datetime): The time for the cookie to expire on the client's browser.
|
|
- ``path`` (string): The subset of URLs to which this cookie applies. Defaults to /.
|
|
- ``comment`` (string): A comment (metadata).
|
|
- ``domain`` (string): Specifies the domain for which the cookie is valid. An
|
|
explicitly specified domain must always start with a dot.
|
|
- ``max-age`` (number): Number of seconds the cookie should live for.
|
|
- ``secure`` (boolean): Specifies whether the cookie will only be sent via HTTPS.
|
|
- ``httponly`` (boolean): Specifies whether the cookie cannot be read by Javascript.
