Use the complete form of send(), that takes a
x::http::responseimpl,
to send cookies to the client.
void received(const x::http::requestimpl &req, bool hasbody) { // ... x::http::responseimpl resp; resp.append(x::http::content_type_header::name, "text/plain; charset=\"utf-8\""); resp.addCookie(x::http::cookie("loggedin", "yes") .setDomain(".example.com") .set_path("/") .setExpiresIn(24 * 60 * 60)); send(resp, req, buffer); }
addCookie() adds a “Set-Cookie”
header, based on the contents of the given
x::http::cookie.
Its constructor takes the cookie's name and value, and additional
method set various cookie properties, such as the cookie's scope and
expiration.
Cookie names and values must follow the constraints on the names and
values of cookies. Cookie names must generally be alphanumeric,
cookie values must consists of US-ASCII characters
excepting control character, quotes, commas, semicolons, and
backslashes.
x::http::requestimpl's
get_cookies() method retrieves any cookies
sent in the client's request:
void received(const x::http::requestimpl &req, bool hasbody) { x::http::cookies_t cookies=req.get_cookies(); // ...
get_cookies() loads the given map with the
contents of any cookies in the request.
