HTTP接口控制以设备控制（向设备下发命令）为例

(* First you need to prepare the following values *)
(* 1. AppID (in your console development settings) *)
(* 2. AppSecret (in your console development settings) *)
(* 3. ts (timestamp of the current time, seconds) *)
(* 4. YourSign = md5(md5(AppSecret)ts);(md5 is an encryption method, AppSecret is the AppSecret prepared above, ts is the timestamp prepared above, concatenate the string after the AppSecret after md5 encryption) *)
(* In simple terms, the signature is md5(md5(your developer password)concatenate the above ts timestamp value); ts is the timestamp of the current timestamp; that is, to perform one MD5 on the developer password (AppSecret), then concatenate the timestamp, and then perform one MD5 on the entire concatenated string *)
(* Core request address: api.thingboot.com/AppID/device/control/?sign=YourSign&&ts=ts; *)
(* Request needs to pass two parameters device and order: *)
(* device[string]: unique device ID, can pass multiple [separated by ,], can be viewed in the console, or pulled through the interface *)
(* order[json string]: the command to be issued, for example: *)
(* {"power":1}, usually to connect the circuit of the switch *)
(* {"power3":0}, usually to close the third line of the switch or controller *)
(* {"play:gbk:16":"hello, welcome to visit"}, let the voice speaker report the specified content *)
(* The same type of product, the command is the same, different product types of commands, please view the product manual page of each product *)
(* Note: you must replace the formal AppID and AppSecret with real-time timestamp calculation of the signature, the request must have device device ID and order command *)

(* 确保安装了必要的库 opam install cohttp digestif *)

open Lwt.Infix
open Cohttp
open Cohttp_lwt_unix

let () =
  (* 配置参数 *)
  let app_id = "实际AppID" in       (* 替换为你的AppID *)
  let app_secret = "实际AppSecret" in (* 替换为你的AppSecret *)
  let device_id = "1878" in         (* 替换为你的设备ID *)
  let command = "{\"power1\":1}" in  (* 替换为你的控制命令 *)

  (* 计算时间戳 *)
  let ts = int_of_float (Unix.time ()) in

  (* 计算签名 [严格按 md5(md5(密码)+时间戳) 逻辑] *)
  let first_md5 = Digestif.MD5.digest_string app_secret |> Digestif.MD5.to_hex in
  let sign_input = first_md5 ^ string_of_int ts in
  let sign = Digestif.MD5.digest_string sign_input |> Digestif.MD5.to_hex in

  (* 构造请求 URL *)
  let url = Printf.sprintf 
    "https://api.thingboot.com/%s/device/control/?sign=%s&ts=%d" 
    app_id sign ts 
  in

  (* 构造请求体 *)
  let request_body =
    let open Yojson.Basic in
    let order = from_string command in
    `Assoc [
      ("device", `String device_id);
      ("order", order)
    ] 
  in

  (* 创建 HTTP 请求 *)
  let headers = Header.add (Header.init ()) "Content-Type" "application/json" in
  let request = Request.make headers `POST (Uri.of_string url) in

  (* 发送请求并处理响应 *)
  let body_str = 
    Client.call request (Body.of_string (Yojson.Basic.to_string request_body))
    >>= fun (response, body) ->
    match response.status with
    | #Http_status.Code.successful_status ->
       Cohttp_lwt.Body.to_string body
    | code ->
       Lwt.return (Printf.sprintf "请求失败: %d" (Http_status.Code.code_of code))
  in

  (* 输出结果 *)
  body_str >>= fun body ->
  print_endline body;
  Lwt.return ()
  |> Lwt_main.run

(* 将上述代码保存为一个 .ml 文件（如 request.ml），然后使用 OCaml 编译器和运行时环境运行 *)
(* ocamlfind opt -linkpkg -package cohttp,digestif,yojson request.ml -o request && ./request *)

说明：{AppID}为您的应用ID（由平台生成），免费注册登录后，可在控制台查看；sign和ts的取值，请参考文档。
