安卓接入onenet的控制软件及调试助手
@安卓接入onenet的控制软件及调试助手
内容：文章叙述了安卓向onenet服务器上传数据，获取数据点，通过onenet向单片机发送命令的内容
关于硬件的问题大家可以问一下我学长大佬(QQ:815794369)
软件源码地址：https://pan.baidu.com/s/1hZjlW6Vnb45Kd3x5c_KQ2Q
开发软件：Android Studio (发送的格式特别严格)
**软件照片和硬件照片 通过onenet平台去控制四个灯的亮灭：
数据格式：
大家应该都用到过小黄人的串口调试z助手，下面这个图片就是通过小黄人向单片机发送开灯的指令（当然指令是自己规定的），这个数据包的格式是固定的，并且官方文档的介绍并不详细。* 后面也会介绍上传数据点和获得数据的格式
下面这个就是利用串口调试助手让单片机上的绿灯亮：
返回的结果是error;0 success 表示成功了，当然你要想更加人性化的话官方的文档里面会介绍返回的数据是什么意思，比如设备是否在线，设备是否响应之类的东西。
**发送命令格式：
在输入框里面输入：
POST http://api.heclouds.com/cmds?device_id=522417343 HTTP/1.1
api-key:HQgSUzUeFhAY=Ict2ildbRkb388=
Host:api.heclouds.com
Content-Length:12
<"greenled:1">
//-------你只要吧device_id， api-key写成你自己产品的就可以了
//注意，注意！！！！！！！！！！！！！！！！！！
POST 后面有一个空格，HTTP/1.1前面有一个空格， Content-Length:下面有一个空行，并且空行里面不能有空格，Content-Length:的大小就是<>里面的字符数，一定要准确不然就会出错
dff这段话的意思就是表示向单片机发送数据greenled:1
**获取数据格式：
在closeContent这一行后面必须要点两次换行，
并且Connection:close下面的空行中不能有空格
GET /devices/522417343/datastreams/Red_Led HTTP/1.1
api-key:HQgSUzUeFhAY=Ict2ildbRkb388=
Host:api.heclouds.com
Connection:close
//--这个 Connection:close下面必须要有一个一个空行，并且空行里面不能有空格，
不然就会出错。
表示获取Red_Led
获取的是onenet平台上Red_Led最新的一次数据
**上传数据格式：
POST /devices/522417343/datapoints?type=3 HTTP/1.1
api-key:HQgSUzUeFhAY=Ict2ildbRkb388=
Host:api.heclouds.com
Content-Length:40
{"GreenLed":22,"RedLed":33,"BlueLed":44}
一定要注意json数据的长度是包含大括号的长度
并且在最后一行的数据前面一定要有一个空行 并且这个
空行是不能有空格的
**onenet上面的数据展示：
onenet上面的数据展示：如果你没有在onenet上面创建数据流模板就发送数据流模板就开始发送数据的话平台会自己帮你创建一个，但是没有创建就获取数据的话就有可能会出错。
**注意：
上传数据和发送命令是不一样的
**我觉得上传数据就是往平台上上传数据，但是发送命令就是给单片机发送指令
