type t
type args = (string * string option) list
type proxy =
| UnsetProxy (** The proxy is forced off. *)
| SystemProxy (** Use the system settings. *)
| ForcedProxy of string (** The proxy is forced to the specified URL. *)
val create : ?curl:string -> ?proxy:proxy -> ?tmpdir:string -> args -> t
(** Create a curl command handle.
The curl arguments are a list of key, value pairs corresponding
to curl command line parameters, without leading dashes,
eg. [("user", Some "user:password")].
The optional [?curl] parameter controls the name of the curl
binary (default ["curl"]).
The optional [?proxy] parameter adds extra arguments to
control the proxy.
Note that some extra arguments are added implicitly:
- [--max-redirs 5] Only follow 3XX redirects up to 5 times.
- [--globoff] Disable URL globbing.
Note this does {b not} enable redirects. If you want to follow
redirects you have to add the ["location"] parameter yourself. *)
val run : t -> string list
(** [run t] runs previously constructed the curl command.
It actually uses the [curl --config] option to pass the arguments
securely to curl through an external file. Thus passwords etc are
not exposed to other users on the same machine.
The result is the output of curl as a list of lines. *)
val to_string : t -> string
(** Convert the curl command line to a string.
This elides any arguments that might contain passwords, so is
useful for debugging. *)
val print : out_channel -> t -> unit
(** Print the curl command line.
This elides any arguments that might contain passwords, so is
useful for debugging. *)
