thingsboard|ThingsBoard 使用 REST API HTTP 方法获取遥测数据属性数据等 ThingsBoard|http

一、方法参考

想通过http方式拿遥测数据，没有通过设备 访问令牌可以获取到的API，HTTP提供的API，只能拿到属性数据
可参考：http://www.ithingsboard.com/docs/reference/http-api/
对此，有2中方法，可以拿到遥测数据
(1).通过REST API的方法，去拿遥测数据（下文介绍的方法）
(2).通过RPC命令，规则链中加脚本，拿到遥测数据后，再回复RPC命令，但这里可以拿到的数据，是服务器范围，我没搞懂什么意思，就没继续研究了，可参考：http://www.ithingsboard.com/docs/user-guide/rule-engine-2-0/tutorials/rpc-reply-tutorial/#%E5%88%9B%E5%BB%BArelated-thermostat-temperature%E8%A7%84%E5%88%99%E9%93%BE

我们也可以打开一下我们自己的swagger-ui.htm看看所有的命令，着重关注于 /values/timeseries

三、实施步骤

使用Postman发送HTTP的请求
注意设置一下Request timeout in ms久一点，具体要看服务器的网络情况，如果太短，会出现失败的情况
设置位置：File-->Settings
