boost::urls::authority_view::encoded_host_address

Return the host

Synopsis

Declared in <boost/url/authority_view.hpp>

pct_string_view
encoded_host_address() const noexcept;

Description

The value returned by this function depends on the type of host returned from the function host_type.

  • If the type is host_type::ipv4, then the IPv4 address string is returned.

  • If the type is host_type::ipv6, then the IPv6 address string is returned, without any enclosing brackets.

  • If the type is host_type::ipvfuture, then the IPvFuture address string is returned, without any enclosing brackets.

  • If the type is host_type::name, then the host name string is returned. Any percent‐escapes in the string are decoded first.

  • If the type is host_type::none, then an empty string is returned. The returned string may contain percent escapes.

Example

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

Complexity

Constant.

Exception Safety

Throws nothing.

BNF

host        = IP-literal / IPv4address / reg-name

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

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