Return the host name
Synopsis
Declared in header <boost/url/authority_view.hpp>
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 / "-" / ".")
