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

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。
