Description
Objects of this type represent valid authority strings constructed from a parsed, external character buffer whose storage is managed by the caller. That is, it acts like a core::string_view in terms of ownership. The caller is responsible for ensuring that the lifetime of the underlying character buffer extends until it is no longer referenced.
Example 1
Construction from a string parses the input as an authority and throws an exception on error. Upon success, the constructed object points to the passed character buffer; ownership is not transferred.
authority_view a( "user:pass@www.example.com:8080" );Example 2
The parsing function parse_authority returns a result containing either a valid authority_view upon succcess, otherwise it contain an error. The error can be converted to an exception by the caller if desired:
system::result< authority_view > rv = parse_authority( "user:pass@www.example.com:8080" );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
