Read the cookies sent with a request

get_cookies() returns the raw Cookie header of the request the session was opened with, and parse_cookie_string() turns that header into a named vector.

Usage

parse_cookie_string(cookie_string)

get_cookies(session = shiny::getDefaultReactiveDomain())

Arguments

cookie_string

The cookie string to parse, as get_cookies() returns it.

session

The {shiny} session object.

Value

For get_cookies(), the Cookie header as a single string, or NULL when the request carried none. For parse_cookie_string(), a named character vector of the cookies it holds, or "" when given NULL. Index it with single brackets: a visitor arriving without a cookie gives nothing to index into, and [[ errors where [ returns NA.

See also

set_cookie() to set one from a response handler, and vignette("cookies") for carrying a session across pages.

Examples

parse_cookie_string("brochure_session=63422; brochure_cookie=3958")
#> brochure_session  brochure_cookie 
#>          "63422"           "3958"
