Same as file but makes possible to specify the content type for each file. The value returned by service handlers is a pair (file_name, content_type).

val check_file : string -> bool

The function check_file file is true if File.send file would effectively return the file (i.e. the file is present and readable)

include Eliom_registration_sigs.S_with_create with type page = string * string and type options = int and type return = Eliom_service.non_ocaml and type result = browser_content kind
include Eliom_registration_sigs.S with type page = string * string with type options = int with type return = Eliom_service.non_ocaml with type result = browser_content kind
type page = string * string
type options = int
type result = browser_content kind

Service registration

val register : ?app:string -> ?scope:[< Eliom_common.scope ] -> ?options:options -> ?charset:string -> ?code:int -> ?content_type:string -> ?headers:Cohttp.Header.t -> ?secure_session:bool -> service: ('get, 'post, _, _, _, Eliom_service.non_ext, Eliom_service.reg, _, _, _, return) Eliom_service.t -> ?error_handler:((string * exn) list -> page Lwt.t) -> ('get -> 'post -> page Lwt.t) -> unit

The function register ~service handler associates the service to the function handler. The handler function takes two parameters, the GET and POST parameters of the current HTTP request, and should return the corresponding page.

The optional parameter ~scope is Eliom_common.global_scope by default. See the Eliom manual for detailed description <<a_manual chapter="server-services" fragment="scope"|of different scopes>>.

The optional parameter ~options is specific to each output module. See the type description for more information.

The optional parameters ?charset, ?code, ?content_type and ?headers can be used to modify the HTTP answer sent by Eliom. Use this with care.

The optional parameter ~secure_session has no effect for scope Eliom_common.global_scope. With other scopes, the parameter is used to force the session service table in which the handler will be registered. By default, the service is registered in the non-secure session if the current request's protocol is http, or in the secure session if the protocol is https. If set to false (resp. true) the handler will be stored in the non-secure (resp. secure) session. See the Eliom manual for an introduction to <<a_manual chapter="server-state"|secure state>>.

The optional parameter ~error_handler is used to specialize the error page when actual parameters aren't compatible with the expected type. The default error handler is fun l -> raise (Eliom_common.Eliom_Typing_Error l) .

val send : ?options:options -> ?charset:string -> ?code:int -> ?content_type:string -> ?headers:Cohttp.Header.t -> page -> result Lwt.t

The function send page builds the HTTP frame corresponding to page. This may be used for example in a service handler registered with Eliom_registration.Any.register, or when building a custom output module.

val create : ?app:string -> ?scope:[< Eliom_common.scope ] -> ?options:options -> ?charset:string -> ?code:int -> ?content_type:string -> ?headers:Cohttp.Header.t -> ?secure_session:bool -> ?https:bool -> ?name:string -> ?csrf_safe:bool -> ?csrf_scope:[< Eliom_common.user_scope ] -> ?csrf_secure:bool -> ?max_use:int -> ?timeout:float -> meth:('m, 'gp, 'gn, 'pp, 'pn, 'tipo, 'gp_) Eliom_service.meth -> path:('att, 'co, 'gp_) Eliom_service.path_option -> ?error_handler:((string * exn) list -> page Lwt.t) -> ('gp -> 'pp -> page Lwt.t) -> ('gp, 'pp, 'm, 'att, 'co, Eliom_service.non_ext, Eliom_service.reg, 'tipo, 'gn, 'pn, return) Eliom_service.t

Create a service and register it at the same time. It calls Eliom_service.create and then performs Eliom_registration_sigs.S.register. Returns the service.

val create_attached_get : ?app:string -> ?scope:[< Eliom_common.scope ] -> ?options:options -> ?charset:string -> ?code:int -> ?content_type:string -> ?headers:Cohttp.Header.t -> ?secure_session:bool -> ?https:bool -> ?name:string -> ?csrf_safe:bool -> ?csrf_scope:[< Eliom_common.user_scope ] -> ?csrf_secure:bool -> ?max_use:int -> ?timeout:float -> fallback: (unit, unit, Eliom_service.get, Eliom_service.att, Eliom_service.non_co, Eliom_service.non_ext, _, [ `WithoutSuffix ], unit, unit, return) Eliom_service.t -> get_params:('gp, [ `WithoutSuffix ], 'gn) Eliom_parameter.params_type -> ?error_handler:((string * exn) list -> page Lwt.t) -> ('gp -> unit -> page Lwt.t) -> ('gp, unit, Eliom_service.get, Eliom_service.att, Eliom_service.co, Eliom_service.non_ext, Eliom_service.reg, [ `WithoutSuffix ], 'gn, unit, return) Eliom_service.t

Create an attached service and register it at the same time. It calls Eliom_service.create_attached_get and then performs Eliom_registration_sigs.S.register. Returns the new service.

val create_attached_post : ?app:string -> ?scope:[< Eliom_common.scope ] -> ?options:options -> ?charset:string -> ?code:int -> ?content_type:string -> ?headers:Cohttp.Header.t -> ?secure_session:bool -> ?https:bool -> ?name:string -> ?csrf_safe:bool -> ?csrf_scope:[< Eliom_common.user_scope ] -> ?csrf_secure:bool -> ?max_use:int -> ?timeout:float -> fallback: ('gp, unit, Eliom_service.get, Eliom_service.att, Eliom_service.non_co, Eliom_service.non_ext, _, [ `WithoutSuffix ], 'gn, unit, return) Eliom_service.t -> post_params:('pp, [ `WithoutSuffix ], 'pn) Eliom_parameter.params_type -> ?error_handler:((string * exn) list -> page Lwt.t) -> ('gp -> 'pp -> page Lwt.t) -> ('gp, 'pp, Eliom_service.post, Eliom_service.att, Eliom_service.co, Eliom_service.non_ext, Eliom_service.reg, [ `WithoutSuffix ], 'gn, 'pn, return) Eliom_service.t

Create an attached POST service and register it at the same time. It calls Eliom_service.create_attached_post and then performs Eliom_registration_sigs.S.register. Returns the new service.
