华为云IOT平台设备获取api调用笔记

目的：验证华为云IOT平台的设备获取接口连通性

1、注册IAM账户

地址：https://console.huaweicloud.com/iam/?region=cn-north-4#/iam/users

选择权限组，

2、创建好IAM后，需要重新登陆，并修改IAM账户密码

地址：https://auth.huaweicloud.com/authui/login.html?locale=zh-cn&service=https%3A%2F%2Fwww.huaweicloud.com%2Fproduct%2Fiothub.html#/login

3、token获取

参考文档：认证鉴权_设备接入 IoTDA_API参考_应用侧API参考_如何调用API_华为云 

在postman中调试接口，

post请求：https://iam.cn-north-4.myhuaweicloud.com/v3/auth/tokens

Header参数：Content-Type:application/json

Body参数：

{ 
    "auth": { 
        "identity": { 
            "methods": [ 
                "password" 
            ], 
            "password": { 
                "user": { 
                    "name": "IAM用户名", 
                    "password": "IAM账户的密码", 
                    "domain": { 
                        "name": "IAM账户名" 
                    } 
                } 
            } 
        }, 
        "scope": { 
            "project": { 
                "name": "项目名" 
            } 
        } 
    } 
}

响应结果，可以看出token在响应头里面：

 4、使用token调用设备获取接口

参考文档地址：https://apiexplorer.developer.huaweicloud.com/apiexplorer/debug?product=IoTDA&api=ListDevices

GET请求地址：https://iotda.cn-north-4.myhuaweicloud.com/v5/iot/5f5d6375d5da4499b241ac5f948a80bf/devices

Headers头部设置参数X-Auth-Token，为token的值

Body参数：无

响应结果：
