节点 js aws-sdk 连接

Question

我有一个像 aruba-get-rds-backups.getaws.arubanetworks.com/sp/ 这样的 s3 存储桶，其中 aruba-get-rds-backups.getaws.arubanetworks.com 是存储桶名称，/sp 是一种子文件夹 如何使用 nodejs 中 aws-sdk 的 getObject 方法访问存储桶中 /sp 文件夹内的文件

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);
    }
})();
