设施基于HTTPS协定接入IoT平台

设施基于HTTPS协定接入IoT平台仅华东2反对官网文档 https://help.aliyun.com/document_detail/58034.html

1.设施身份认证:通过三元组获取token

HTTPS服务器地址为 https://iot-as-http.cn-shanghai.aliyuncs.com/>



认证申请示例：

POST /auth HTTP/1.1Host: iot-as-http.cn-shanghai.aliyuncs.comContent-Type: application/jsonbody: {    "version": "default",    "clientId": "mylight1000002",    "signmethod": "hmacsha1",    "sign": "4870141D4067227128CBB4377906C3731CAC221C",    "productKey": "ZG1EvTEa7NN",    "deviceName": "NlwaSPXsCpTQuh8FxBGH",    "timestamp": "1501668289957"}

返回示例：

{  "code": 0,//业务状态码  "message": "success",//业务信息  "info": {    "token":  "6944e5bfb92e4d4ea3918d1eda3942f6"  }}

2.设施数据上报

HTTPS服务器地址为 https://iot-as-http.cn-shanghai.aliyuncs.com/topic/${topic}

申请示例：

POST /topic/a1GFjLP3xxC/device123/pubHost: iot-as-http.cn-shanghai.aliyuncs.compassword:${token}Content-Type: application/octet-streambody: ${your_data}

返回示例

{  "code": 0,//业务状态码  "message": "success",//业务信息  "info": {    "messageId": 892687627916247040  }}
