S3.getObject NodeJS Contoh
const { GetObjectCommand, S3Client } = require('@aws-sdk/client-s3')
const client = new S3Client() // Pass in opts to S3 if necessary
function getObject (Bucket, Key) {
return new Promise(async (resolve, reject) => {
const getObjectCommand = new GetObjectCommand({ Bucket, Key })
try {
const response = await client.send(getObjectCommand)
// Store all of data chunks returned from the response data stream
// into an array then use Array#join() to use the returned contents as a String
let responseDataChunks = []
// Handle an error while streaming the response body
response.Body.once('error', err => reject(err))
// Attach a 'data' listener to add the chunks of data to our array
// Each chunk is a Buffer instance
response.Body.on('data', chunk => responseDataChunks.push(chunk))
// Once the stream has no more data, join the chunks into a string and return the string
response.Body.once('end', () => resolve(responseDataChunks.join('')))
} catch (err) {
// Handle the error or throw
return reject(err)
}
})
