Return the host name.
template< class StringToken = string_token::return_string> StringToken::result_type host_name( StringToken&& token = {}) const;
If the host type is host_type::name
, this function returns the
name as a string. Otherwise, if the host type is not an name, it returns
an empty string. Any percent-escapes in the string are decoded first.
assert( url_view( "https://www%2droot.example.com/" ).host_name() == "www-root.example.com" );
Linear in this->host_name().size()
.
Calls to allocate may throw.
host = IP-literal / IPv4address / reg-name IP-literal = "[" ( IPv6address / IPvFuture ) "]" reg-name = *( unreserved / pct-encoded / "-" / "." )
