AWS SDK를 사용하여 Amazon S3 버킷 및 객체 시작하기

다음 코드 예제는 다음과 같은 작업을 수행하는 방법을 보여줍니다.

• 버킷을 만들고 버킷에 파일을 업로드합니다.

• 버킷에서 객체를 다운로드합니다.

• 버킷의 하위 폴더에 객체를 복사합니다.

• 버킷의 객체를 나열합니다.

• 버킷 객체와 버킷을 삭제합니다.

GitHub에 더 많은 내용이 있습니다. AWS 코드 예제 리포지토리에서 전체 예제를 찾고 설정 및 실행하는 방법을 배워보세요.

먼저 필요한 모듈을 모두 가져옵니다.

// Used to check if currently running file is this file.
import { fileURLToPath } from "url";
import { readdirSync, readFileSync, writeFileSync } from "fs";

// Local helper utils.
import { dirnameFromMetaUrl } from "@aws-doc-sdk-examples/lib/utils/util-fs.js";
import { Prompter } from "@aws-doc-sdk-examples/lib/prompter.js";
import { wrapText } from "@aws-doc-sdk-examples/lib/utils/util-string.js";

import {
  S3Client,
  CreateBucketCommand,
  PutObjectCommand,
  ListObjectsCommand,
  CopyObjectCommand,
  GetObjectCommand,
  DeleteObjectsCommand,
  DeleteBucketCommand,
} from "@aws-sdk/client-s3";

이전 가져오기는 일부 도우미 유틸리티를 참조합니다. 이러한 유틸리티는 이 섹션의 시작 부분에 연결된 GitHub 리포지토리에 로컬로 제공됩니다. 참조를 위해 해당 유틸리티의 다음 구현을 참조하십시오.

export const dirnameFromMetaUrl = (metaUrl) =>
  fileURLToPath(new URL(".", metaUrl));

import { select, input, confirm, checkbox } from "@inquirer/prompts";

export class Prompter {
  /**
   * @param {{ message: string, choices: { name: string, value: string }[]}} options
   */
  select(options) {
    return select(options);
  }

  /**
   * @param {{ message: string }} options
   */
  input(options) {
    return input(options);
  }

  /**
   * @param {string} prompt
   */
  checkContinue = async (prompt = "") => {
    const prefix = prompt && prompt + " ";
    let ok = await this.confirm({
      message: `${prefix}Continue?`,
    });
    if (!ok) throw new Error("Exiting...");
  };

  /**
   * @param {{ message: string }} options
   */
  confirm(options) {
    return confirm(options);
  }

  /**
   * @param {{ message: string, choices: { name: string, value: string }[]}} options
   */
  checkbox(options) {
    return checkbox(options);
  }
}

export const wrapText = (text, char = "=") => {
  const rule = char.repeat(80);
  return `${rule}\n    ${text}\n${rule}\n`;
};

S3의 객체는 '버킷'에 저장됩니다. 새 버킷을 만들기 위한 함수를 정의해 보겠습니다.

export const createBucket = async () => {
  const bucketName = await prompter.input({
    message: "Enter a bucket name. Bucket names must be globally unique:",
  });
  const command = new CreateBucketCommand({ Bucket: bucketName });
  await s3Client.send(command);
  console.log("Bucket created successfully.\n");
  return bucketName;
};

버킷에는 '객체'가 포함됩니다. 이 함수는 디렉터리의 콘텐츠를 버킷에 객체로 업로드합니다.

export const uploadFilesToBucket = async ({ bucketName, folderPath }) => {
  console.log(`Uploading files from ${folderPath}\n`);
  const keys = readdirSync(folderPath);
  const files = keys.map((key) => {
    const filePath = `${folderPath}/${key}`;
    const fileContent = readFileSync(filePath);
    return {
      Key: key,
      Body: fileContent,
    };
  });

  for (let file of files) {
    await s3Client.send(
      new PutObjectCommand({
        Bucket: bucketName,
        Body: file.Body,
        Key: file.Key,
      }),
    );
    console.log(`${file.Key} uploaded successfully.`);
  }
};

객체를 업로드한 후 객체가 올바르게 업로드되었는지 확인하십시오. 이를 위해 ListObjects를 사용할 수 있습니다. 'Key' 속성을 사용하겠지만 응답에는 다른 유용한 속성도 있습니다.

export const listFilesInBucket = async ({ bucketName }) => {
  const command = new ListObjectsCommand({ Bucket: bucketName });
  const { Contents } = await s3Client.send(command);
  const contentsList = Contents.map((c) => ` • ${c.Key}`).join("\n");
  console.log("\nHere's a list of files in the bucket:");
  console.log(contentsList + "\n");
};

때로는 한 버킷에서 다른 버킷으로 객체를 복사하고 싶을 수도 있습니다. 이를 위해서는 CopyObject 명령을 사용하십시오.

export const copyFileFromBucket = async ({ destinationBucket }) => {
  const proceed = await prompter.confirm({
    message: "Would you like to copy an object from another bucket?",
  });

  if (!proceed) {
    return;
  } else {
    const copy = async () => {
      try {
        const sourceBucket = await prompter.input({
          message: "Enter source bucket name:",
        });
        const sourceKey = await prompter.input({
          message: "Enter source key:",
        });
        const destinationKey = await prompter.input({
          message: "Enter destination key:",
        });

        const command = new CopyObjectCommand({
          Bucket: destinationBucket,
          CopySource: `${sourceBucket}/${sourceKey}`,
          Key: destinationKey,
        });
        await s3Client.send(command);
        await copyFileFromBucket({ destinationBucket });
      } catch (err) {
        console.error(`Copy error.`);
        console.error(err);
        const retryAnswer = await prompter.confirm({ message: "Try again?" });
        if (retryAnswer) {
          await copy();
        }
      }
    };
    await copy();
  }
};

버킷에서 여러 객체를 가져오는 SDK 메서드는 없습니다. 대신, 다운로드 및 반복할 객체 목록을 생성하겠습니다.

export const downloadFilesFromBucket = async ({ bucketName }) => {
  const { Contents } = await s3Client.send(
    new ListObjectsCommand({ Bucket: bucketName }),
  );
  const path = await prompter.input({
    message: "Enter destination path for files:",
  });

  for (let content of Contents) {
    const obj = await s3Client.send(
      new GetObjectCommand({ Bucket: bucketName, Key: content.Key }),
    );
    writeFileSync(
      `${path}/${content.Key}`,
      await obj.Body.transformToByteArray(),
    );
  }
  console.log("Files downloaded successfully.\n");
};

이제 리소스를 정리할 차례입니다. 삭제하려면 버킷이 비어 있어야 합니다. 이 두 함수는 버킷을 비우고 삭제합니다.

export const emptyBucket = async ({ bucketName }) => {
  const listObjectsCommand = new ListObjectsCommand({ Bucket: bucketName });
  const { Contents } = await s3Client.send(listObjectsCommand);
  const keys = Contents.map((c) => c.Key);

  const deleteObjectsCommand = new DeleteObjectsCommand({
    Bucket: bucketName,
    Delete: { Objects: keys.map((key) => ({ Key: key })) },
  });
  await s3Client.send(deleteObjectsCommand);
  console.log(`${bucketName} emptied successfully.\n`);
};

export const deleteBucket = async ({ bucketName }) => {
  const command = new DeleteBucketCommand({ Bucket: bucketName });
  await s3Client.send(command);
  console.log(`${bucketName} deleted successfully.\n`);
};

'main' 함수는 모든 것을 한데 가져옵니다. 이 파일을 직접 실행하면 main 함수가 호출됩니다.

const main = async () => {
