Return a reference to a parsed URL string

Synopsis

Declared in <boost/url/parse.hpp>

system::result<url_view>
parse_uri(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_uri( "https://www.example.com/index.htm?id=guest#s1" );

BNF

URI           = scheme ":" hier-part [ "?" query ] [ "#" fragment ]

hier-part     = "//" authority path-abempty
              / path-absolute
              / path-rootless
              / path-empty
