type server
(** Promise a running RPC server. To call an RPC at /p/a/t/h/ in the
provided service, one must call the URI /call/p/a/t/h/. Calling
/list/p/a/t/h/ will list the services prefixed by /p/a/t/h/, if
any. Calling /schema/p/a/t/h/ will describe the input and output
of the service, if it is callable. Calling /pipe will read a
sequence of services to call in sequence from the request body,
see {!pipe_encoding}.
The arguments cors_allowed_origins and cors_allowed_headers define
the cross-origin resource sharing using the headers
Access-Control-Allow-Origin and Access-Control-Allow-Headers. The
argument cors_allowed_headers sets the content of
Access-Control-Allow-Headers. Since you cannot have multiple
values for Access-Control-Allow-Origin, the server accepts a list
in cors_allowed_origins and matches it against the origin of the
incoming request; then returns the longest element of the passed
list as the content of Access-Control-Allow-Origin.
The optional [pre_hook] is called with the path part of the URL
before resolving each request, to delegate the answering to
another resolution mechanism. Its result is ignored if the return
code is [404]. The optional [post_hook] is called if both the
[pre_hook] and the serviced answered with a [404] code. [pre_hook] and
[post_hook] return a pair made of an optional Content-Type value and the
answer. *)
