У меня есть приложение aws без сервера в nodejs. Я создал s3 bucket, vp c и конечную точку s3, как показано ниже в serverless.yml

, которую я разработал для генерации предварительно назначенного URL-адреса s3 с помощью приведенного ниже кода. 

import AWS from 'aws-sdk';

const s3 = new AWS.S3({ signatureVersion: 'v4' });
const bucket = process.env.S3_BUCKET;

const signedUrl = async fileName => {
  const params = {
    Bucket: bucket,
    Key: `uploads/${fileName}`,
    Expires: 3600
  };
  const s3signedUrl = await new Promise((resolve, reject) => {
    s3.getSignedUrl('putObject', params, (err, url) => {
      if (err) reject(err);
      resolve(url);
    });
  });
  return s3signedUrl;
};

export default signedUrl;

VP C создается, а также конечная точка s3 и политика сегмента в сегменте s3. что я не понимаю, так это то, как я могу получить предварительно назначенный URL через конечную точку s3. Я получаю предварительно назначенный URL-адрес, как показано ниже: https://resourcesbucket-reports-shamila.s3.eu-west-2.amazonaws.com/uploads/test1.png?X-Amz-Algorithm=AWS4-FxBTrgAZ4lO4PUA2n7MxyhRUEgZOnZyGnvXRPqMiiWEoayD5%2 ...

Загрузка файлов успешно осуществляется через этот предварительно назначенный URL-адрес. Как получить предопределенный URL-адрес через созданную конечную точку vp c s3?
