authentication_scheme_codes/3 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Splits authentication value codes into the scheme and remaining payload codes at the first HTTP optional whitespace code.

| Compilation flags: | static

| Template: | authentication_scheme_codes(Codes,SchemeCodes,PayloadCodes) | Mode and number of proofs: | authentication_scheme_codes(+list(integer),-list(integer),-list(integer)) - one

.. index:: parse_authentication_parameters/3 .. _http_authentication_helpers/0::parse_authentication_parameters/3:

parse_authentication_parameters/3 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Parses comma-separated authentication parameters, using the given domain-error term for invalid syntax and duplicate names.

| Compilation flags: | static

| Template: | parse_authentication_parameters(ErrorDomain,Codes,Pairs) | Mode and number of proofs: | parse_authentication_parameters(+nonvar,+list(integer),-list(pair)) - one_or_error

.. index:: authentication_token_codes/1 .. _http_authentication_helpers/0::authentication_token_codes/1:

authentication_token_codes/1 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Succeeds when the nonempty list of codes is an HTTP token.
