Question

我有一个s3桶，如aruba-get-rds-backups.getaws.arubanetworks.com/sp/，其中aruba-get-rds-backups.getaws.arubanetworks.com是桶名，/sp是一种子文件夹如何访问桶内/sp文件夹中的文件使用nodejs的aws-sdk的getObject方法

Answer 1

async function getS3Obj(bucketName, bucketKey) {
let AWS = require("aws-sdk");
let s3 = new AWS.S3({ apiVersion: "2006-03-01" }); // provide credentials, if needed
const params = {
Bucket: bucketName,
Key: bucketKey,
};
let content = await s3.getObject(params).promise();
// assuming here you're downloading ascii file
return content.Body!==undefined ? content.Body.toString() : null;
}
( async () =>{
try {

// your call will likely to be something...
const content = await getS3Obj("bucketName", "sp/file.txt");
console.log(content);
} catch (error) {
console.log(error);
}
})();
