Struct ThreeTuple

Source
pub struct ThreeTuple {
    pub product_key: String,
    pub device_name: String,
    pub device_secret: String,
}
Expand description

设备认证三元组。

这个三元组除了在一型一密的动态注册中用不到之外,所有和阿里云物联网平台发起的连接都要有这三元组生成签名。

Fields§

§product_key: String

产品 ProductKey,即所谓”型“。参考创建产品

§device_name: String

设备 DeviceName,即所谓”机“。参考创建设备

§device_secret: String

设备 DeviceSecret,即所谓”密“。参考设备安全认证设备获取设备证书

Implementations§

Source§

impl ThreeTuple

Source

pub fn from_env() -> Self

从下列环境变量中读取三元组。

  • PRODUCT_KEY
  • DEVICE_NAME
  • DEVICE_SECRET

这个方法在示例代码中多处用到,但实际生产环境中建议自行编写初始化逻辑。

§Examples
std::env::set_var("PRODUCT_KEY", "a");
std::env::set_var("DEVICE_NAME", "b");
std::env::set_var("DEVICE_SECRET", "c");

use aiot::ThreeTuple;

let three = ThreeTuple::from_env();
assert_eq!("a", &three.product_key);
assert_eq!("b", &three.device_name);
assert_eq!("c", &three.device_secret);
§Panics

如果没有设置对应的环境变量,该方法将 panic。
