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.

Reading cookies

A user's cookies can be accessed Request object's cookie dictionary.

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.

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

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.
• 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.
