parse_authority

Parse an authority.

Synopsis

Defined in header <boost/url/authority_view.hpp>

result< authority_view >
parse_authority(
    string_view s);
Description

This function parses a string according to the authority grammar below, and returns an authority_view referencing the string. Ownership of the string is not transferred; the caller is responsible for ensuring that the lifetime of the string extends until the view is no longer being accessed.

BNF
authority     = [ userinfo "@" ] host [ ":" port ]

userinfo      = user [ ":" [ password ] ]

user          = *( unreserved / pct-encoded / sub-delims )
password      = *( unreserved / pct-encoded / sub-delims / ":" )

host          = IP-literal / IPv4address / reg-name

port          = *DIGIT
Exception Safety

Throws nothing.
