Javascript 如何使用typescript访问AWS SQS SendMessageResult中的$response属性？

我正在向SQS队列发送一条消息，如下所示：

const queueName = 'some_queue_name';
const foo = 'foo';
const bar = 'bar';

const sqs = new AWS.SQS();
const SendMessageRequest: AWS.SQS.SendMessageRequest = {
  MessageBody: JSON.stringify({ foo, bar }),
  QueueUrl: queueName,
};

try {
  const request = sqs.sendMessage(SendMessageRequest, function (err, data) {
    if (err) {
      console.log('Error', err);
    } 
  });

  const smgResponse: SendMessageResult = await request.promise();

} catch (err) {
  console.log(err);
  expect(err).toBeUndefined();
}

在运行时，

SendMessageRequest

显示一个

$response

属性，但该属性在对象定义中不可见。运行时访问此属性的最佳方式是什么？

使用：

用运行时的任何类型的

$response

替换

unknown

如果要执行大量断言，可以为此创建一个新类型：

interface SendMessageResultWithResponse extends {
  $response: unknown
}

// alternatively type SendMessageResultWithResponse = SendMessageResult & {$response: unknown}

const smgResponse = await request.promise() as SendMessageResultWithResponse

interface SendMessageResultWithResponse extends {
  $response: unknown
}

// alternatively type SendMessageResultWithResponse = SendMessageResult & {$response: unknown}

const smgResponse = await request.promise() as SendMessageResultWithResponse
