(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, if the host type is not an name, it returns an empty string. Any percent-escapes in the string are decoded first.

Example

assert( url_view( "https://www%2droot.example.com/" ).host_name() == "www-root.example.com" );

Complexity

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

Exception Safety

Calls to allocate may throw.

BNF

host        = IP-literal / IPv4address / reg-name

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

reg-name    = *( unreserved / pct-encoded / "-" / ".")
