#### [ JavaScript ]

**SDK for JavaScript (v3)**  
 查看 GitHub，了解更多信息。在 [Amazon 代码示例存储库](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javascriptv3/example_code/s3#code-examples)中查找完整示例，了解如何进行设置和运行。
删除给定 Amazon S3 存储桶的所有对象。  

```
import {
  DeleteObjectsCommand,
  paginateListObjectsV2,
  S3Client,
} from "@aws-sdk/client-s3";

/**
 *
 * @param {{ bucketName: string }} config
 */
export const main = async ({ bucketName }) => {
  const client = new S3Client({});
  try {
    console.log(`Deleting all objects in bucket: ${bucketName}`);

    const paginator = paginateListObjectsV2(
      { client },
      {
        Bucket: bucketName,
      },
    );

    const objectKeys = [];
    for await (const { Contents } of paginator) {
      objectKeys.push(...Contents.map((obj) => ({ Key: obj.Key })));
    }

    const deleteCommand = new DeleteObjectsCommand({
      Bucket: bucketName,
      Delete: { Objects: objectKeys },
    });

    await client.send(deleteCommand);

    console.log(`All objects deleted from bucket: ${bucketName}`);
  } catch (caught) {
    if (caught instanceof Error) {
      console.error(
        `Failed to empty ${bucketName}. ${caught.name}: ${caught.message}`,
      );
    }
  }
};

// Call function if run directly.
import { fileURLToPath } from "node:url";
import { parseArgs } from "node:util";
if (process.argv[1] === fileURLToPath(import.meta.url)) {
  const options = {
    bucketName: {
      type: "string",
    },
  };

  const { values } = parseArgs({ options });
  main(values);
}
