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

/*
确保在 pubspec.yaml 文件中添加以下依赖：
dependencies:
  http: ^0.13.5
  crypto: ^3.0.2
*/

import 'dart:convert';
import 'package:http/http.dart' as http;
import 'package:crypto/crypto.dart';

void main() async {
  // 配置参数
  final AppID = 'qtyVWcgeMq'; // 替换为实际的 AppID
  final AppSecret = '开发者密码'; // 替换为实际的 AppSecret
  final device = '1878'; // 替换为实际的设备ID；可传多个[用,间隔]
  final order = '{"power1":1}'; // 替换为实际的命令

  // 计算时间戳
  final ts = DateTime.now().millisecondsSinceEpoch;

  // 计算 MD5 哈希值
  final md5Hash = md5.convert(utf8.encode(AppSecret)).toString();

  // 计算 sign
  final signInput = md5Hash + ts.toString();
  final sign = md5.convert(utf8.encode(signInput)).toString();

  // 构造请求 URL
  final url = 'https://api.thingboot.com/$AppID/device/control/?sign=$sign&ts=$ts';

  // 创建 multipart 请求
  var request = http.MultipartRequest('POST', Uri.parse(url));

  // 添加请求头
  request.headers.addAll({
    'Accept': '*/*',
    'Host': 'api.thingboot.com',
    'Connection': 'keep-alive',
  });

  // 添加请求体字段
  request.fields.addAll({
    'device': device,
    'order': order,
  });

  // 发送请求
  var response = await request.send();

  // 输出响应
  if (response.statusCode == 200) {
    print(await response.stream.bytesToString());
  } else {
    print(response.reasonPhrase);
  }
}

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。
