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

#确保安装了必要的包：
#install.packages("httr")
#install.packages("digest")

library(httr)
library(digest)

# 配置参数
app_id <- "qtyVWcgeMq"  # 替换为实际的 AppID
app_secret <- "开发者密码"  # 替换为实际的 AppSecret
device <- "1878"  # 替换为实际的设备 ID
order <- '{"power1":1}'  # 替换为实际的命令

# 计算时间戳
ts <- as.numeric(Sys.time()) * 1000  # 转换为毫秒

# 计算 MD5 哈希值
md5_hash <- digest(app_secret, algo = "md5", serialize = FALSE)

# 计算 sign
sign_input <- paste0(md5_hash, ts)
sign <- digest(sign_input, algo = "md5", serialize = FALSE)

# 构造请求 URL
url <- sprintf("https://api.thingboot.com/%s/device/control/?sign=%s&ts=%d", app_id, sign, ts)

# 创建请求体
body <- list(
  device = device,
  order = order
)

# 发送请求
response <- POST(
  url,
  body = body,
  encode = "multipart",
  add_headers(
    `Accept` = "*/*",
    `Host` = "api.thingboot.com",
    `Connection` = "keep-alive"
  )
)

# 输出响应
if (http_status(response)$category == "Success") {
  print(content(response, "text"))
} else {
  print(http_status(response)$message)
}

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。
