boost::urls::url_view_base::encoded_zone_id

Return the IPv6 Zone ID

Synopsis

Declared in <include/boost/url/url_view_base.hpp>

pct_string_view
encoded_zone_id() const noexcept;
cpp

Description

If the host type is host_type::ipv6, this function returns the Zone ID as a string. Otherwise an empty string is returned. The returned string may contain percent escapes.

assert( url_view( "http://[fe80::1%25eth0]/" ).encoded_zone_id() == "eth0" );
cpp

Complexity

Constant.

Exception Safety

Throws nothing.

host        = IP-literal / IPv4address / reg-name

IP-literal = "[" ( IPv6address / IPv6addrz / IPvFuture  ) "]"

ZoneID = 1*( unreserved / pct-encoded )

IPv6addrz = IPv6address "%25" ZoneID
