구현

1. Lamnda 구현

const AWS = require('aws-sdk');

exports.handler = async (event) => {
    AWS.config.region = 'ap-northeast-1';
    const s3 = new AWS.S3();
    try {
        let data = await s3.getObject({
            Bucket: 'bucket_name',
            Key: 'path/to/file.html'
        }).promise();

        return {
            statusCode: 200,
            headers: {"Content-Type": "text/html"},
            body: data.Body.toString(),
        };
    } catch (e) {
        return {
            statusCode: 500,
            body: JSON.stringify(e.message),
        };
    }
};
