Je télécharge actuellement des objets simples vers S3 en utilisant comme suit:
var options = {
Bucket: bucket,
Key: s3Path,
Body: body,
ACL: s3FilePermissions
};
S3.putObject(options,
function (err, data) {
//console.log(data);
});
Mais lorsque j'ai un grand dossier de ressources, par exemple, j'utilise l'outil AWS CLI .
Je me demandais, existe-t-il un moyen natif de faire la même chose avec le sdk d’aws (télécharger des dossiers entiers sur s3)?
Vieille école de manière récursive, j'ai fouetté très vite. N'utilise que des modules de nœud principaux et AWS sdk standard.
var AWS = require('aws-sdk');
var path = require("path");
var fs = require('fs');
const uploadDir = function(s3Path, bucketName) {
let s3 = new AWS.S3();
function walkSync(currentDirPath, callback) {
fs.readdirSync(currentDirPath).forEach(function (name) {
var filePath = path.join(currentDirPath, name);
var stat = fs.statSync(filePath);
if (stat.isFile()) {
callback(filePath, stat);
} else if (stat.isDirectory()) {
walkSync(filePath, callback);
}
});
}
walkSync(s3Path, function(filePath, stat) {
let bucketPath = filePath.substring(s3Path.length+1);
let params = {Bucket: bucketName, Key: bucketPath, Body: fs.readFileSync(filePath) };
s3.putObject(params, function(err, data) {
if (err) {
console.log(err)
} else {
console.log('Successfully uploaded '+ bucketPath +' to ' + bucketName);
}
});
});
};
uploadDir("path to your folder", "your bucket name");
Un merci spécial à ALi de ce post pour avoir aidé à obtenir les noms de fichiers
Je contemplais ce problème l'autre jour et je pensais à quelque chose comme ceci:
...
var async = require('async'),
fs = require('fs'),
path = require("path");
var directoryName = './test',
directoryPath = path.resolve(directoryName);
var files = fs.readdirSync(directoryPath);
async.map(files, function (f, cb) {
var filePath = path.join(directoryPath, f);
var options = {
Bucket: bucket,
Key: s3Path,
Body: fs.readFileSync(filePath),
ACL: s3FilePermissions
};
S3.putObject(options, cb);
}, function (err, results) {
if (err) console.error(err);
console.log(results);
});
Vous pouvez essayer le node-s3-client .
UPDATE: Disponible sur npm ici
À partir de la synchronisation d’un répertoire vers s3 docs :
UPDATE: Ajout du code d'inialisation du client.
var client = s3.createClient({
maxAsyncS3: 20, // this is the default
s3RetryCount: 3, // this is the default
s3RetryDelay: 1000, // this is the default
multipartUploadThreshold: 20971520, // this is the default (20 MB)
multipartUploadSize: 15728640, // this is the default (15 MB)
s3Options: {
accessKeyId: "YOUR ACCESS KEY",
secretAccessKey: "YOUR SECRET ACCESS KEY"
}
});
var params = {
localDir: "some/local/dir",
deleteRemoved: true, // default false, whether to remove s3 objects
// that have no corresponding local file.
s3Params: {
Bucket: "s3 bucket name",
Prefix: "some/remote/dir/",
// other options supported by putObject, except Body and ContentLength.
// See: http://docs.aws.Amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html#putObject-property
},
};
var uploader = client.uploadDir(params);
uploader.on('error', function(err) {
console.error("unable to sync:", err.stack);
});
uploader.on('progress', function() {
console.log("progress", uploader.progressAmount, uploader.progressTotal);
});
uploader.on('end', function() {
console.log("done uploading");
});
voici une version nettoyée/déboguée/fonctionnelle de la solution de @ Jim
function uploadArtifactsToS3() {
const artifactFolder = `logs/${config.log}/test-results`;
const testResultsPath = './test-results';
const walkSync = (currentDirPath, callback) => {
fs.readdirSync(currentDirPath).forEach((name) => {
const filePath = path.join(currentDirPath, name);
const stat = fs.statSync(filePath);
if (stat.isFile()) {
callback(filePath, stat);
} else if (stat.isDirectory()) {
walkSync(filePath, callback);
}
});
};
walkSync(testResultsPath, async (filePath) => {
let bucketPath = filePath.substring(testResultsPath.length - 1);
let params = {
Bucket: process.env.SOURCE_BUCKET,
Key: `${artifactFolder}/${bucketPath}`,
Body: fs.readFileSync(filePath)
};
try {
await s3.putObject(params).promise();
console.log(`Successfully uploaded ${bucketPath} to s3 bucket`);
} catch (error) {
console.error(`error in uploading ${bucketPath} to s3 bucket`);
throw new Error(`error in uploading ${bucketPath} to s3 bucket`);
}
});
}
