调用接口示例

数字签名

API使用摘要签名认证方式（APP Key和APP Secret), 客户端在调用API时，需要使用签名密钥对请求内容进行签名计算, 并将签名同步传输给服务器端进行签名验证。API网关提供的SDK内置了签名实现, 您只需要将签名密钥配置在SDK中。

登录工业数据应用平台，选择左边菜单栏“应用”-“应用授权”，“创建AppKey/AppSecret”或者使用已有的AppKey/AppSecret。

Java-SDK

SDK地址： https://github.com/aliyun/alibabacloud-iot-api-gateway-sdk

Maven依赖：

        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>iotapigateway</artifactId>
            <version>0.0.1</version>
        </dependency>
