static_url::host_name

(Inherited from url_view_base)

Return the host name.

Synopsis
template<
    class StringToken = string_token::return_string>
StringToken::result_type
host_name(
    StringToken&& token = {}) const;
Description

If the host type is host_type::name, this function returns the name as a string. Otherwise an empty string is returned. Any percent-escapes in the string are decoded first.

Example
assert( [link url.ref.boost__urls__url_view_base.url_view `url_view`]( "https://www%2droot.example.com/" ).[link url.ref.boost__urls__static_url.host_name `host_name`]() == "www-root.example.com" );
Complexity

Linear in this->host_name().size().

Exception Safety

Calls to allocate may throw.

BNF
[link url.ref.boost__urls__static_url.host `host`]        = IP-literal / IPv4address / reg-[link url.ref.boost__urls__host_type `name`]

IP-literal  = "[" ( IPv6address / IPvFuture  ) "]"

reg-[link url.ref.boost__urls__host_type `name`]    = *( unreserved / pct-encoded / "-" / "." )
