[网络协议]ThingsBoard 使用 REST API HTTP 方法获取遥测数据 属性数据等

一、方法参考

1. 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/
2. 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

二、方法步骤

1. 参考方法的地址
   http://www.ithingsboard.com/docs/api/
   
   http://www.ithingsboard.com/docs/user-guide/telemetry/#data-query-api

2. 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

1. 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
   

2. 获取JWT_TOKEN

   配置参数	值
   地址	http://xxxx:8080/api/auth/login
   方法	POST
   content-type	application /json
   BODY 数据	{“username”:“tenant@thingsboard.org”,“password”:“tenant”}

   
   
   之后获取到Token
   
   整个请求的Log如下

   POST http://xxxx:8080/api/auth/login
   
   POST /api/auth/login HTTP/1.1

3. 获取遥测数据

   配置参数	值
   地址	http://xxxx:8080/api/plugins/telemetry/DEVICE/4afd0a80-58cd-11ec-9209-b7aebb52f70b/values/timeseries (注意这里DEVICE后面的是设备ID)(最后可通过 ? 来对数据进行筛选)
   方法	GET
   content-type	application /json
   X-Authorization	Bearer (注意这里后面有一个空格)加上JWT_TOKEN
   BODY 数据	无

   
   整个请求的Log如下
