Function authority_view:: host_name

Return the host name

Synopsis

            template
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 / "-" / ".")
