获取阿里云Mqtt连接密码的JavaScript源码（HMACSHA1算法）

通过HMACSHA1算法获取阿里云Mqtt连接密码的JavaScript源码，可以帮助用户更便捷地连接阿里云Mqtt服务。以下是相关的代码示例：

const crypto = require('crypto');



function getMqttPassword(accessKeySecret, clientId, timestamp) {

  const signString = `${clientId}&${timestamp}`;

  const hmac = crypto.createHmac('sha1', accessKeySecret);

  hmac.update(signString);

  const signature = hmac.digest('base64');

  return signature;

}



// 示例

const accessKeySecret = 'your-access-key-secret';

const clientId = 'your-client-id';

const timestamp = Date.now();

const password = getMqttPassword(accessKeySecret, clientId, timestamp);

console.log(password);
