boost::urls::parse_relative_ref

Return a reference to a parsed URL string

Synopsis

Declared in <boost/url/parse.hpp>

constexpr
system::result<url_view>
parse_relative_ref(core::string_view s);

Description

This function parses a string according to the grammar below and returns a view referencing the passed string upon success, else returns an error. Ownership of the string is not transferred; the caller is responsible for ensuring that the lifetime of the character buffer extends until the view is no longer being accessed.

Example


system::result< url_view > = parse_relative_ref( "images/dot.gif?v=hide#a" );

BNF


relative-ref  = relative-part [ "?" query ] [ "#" fragment ]

relative-part = "//" authority path-abempty
              / path-absolute
              / path-noscheme
              / path-abempty
              / path-empty
