如何使用CodePipeline删除S3中的文件

const AWS = require('aws-sdk');
const s3 = new AWS.S3();

exports.handler = async (event) => {
  const bucketName = 'your-bucket-name';
  const fileName = 'file-to-delete.txt';

  const params = {
    Bucket: bucketName,
    Key: fileName
  };

  try {
    await s3.deleteObject(params).promise();
    console.log(`File ${fileName} deleted successfully from S3 bucket ${bucketName}`);
    return {
      statusCode: 200,
      body: 'File deleted successfully'
    };
  } catch (error) {
    console.error(`Error deleting file ${fileName} from S3 bucket ${bucketName}: ${error}`);
    return {
      statusCode: 500,
      body: 'Error deleting file'
    };
  }
};
