我目前使用如下方式将单个对象上传到 S3：
var options = {
Bucket: bucket,
Key: s3Path,
Body: body,
ACL: s3FilePermissions
};
S3.putObject(options,
function (err, data) {
//console.log(data);
});
但是，例如，当我有一个大型资源文件夹时，我会使用AWS CLI工具。
我想知道，有没有一种本地方法可以用 aws sdk 做同样的事情（将整个文件夹上传到 s3）？
老派的递归方式我匆匆忙忙起来。仅使用核心节点模块和标准 AWS sdk。
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");
特别感谢这篇文章中的 Ali帮助获取文件名
这是@Jim 解决方案的清理/调试/工作版本
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`);
}
});
}
如果您需要使用现代 JavaScript 语法并与 TypeScript 兼容的解决方案，我想出了以下代码。递归 getFiles 是从这个答案中借来的（经过这么多年，递归仍然让我头疼，哈哈）。
import { promises as fs, createReadStream } from 'fs';
import * as path from 'path';
import { S3 } from 'aws-sdk';
async function uploadDir(s3Path: string, bucketName: string) {
const s3 = new S3();
// Recursive getFiles from
// https://stackoverflow.com/a/45130990/831465
async function getFiles(dir: string): Promise<string | string[]> {
const dirents = await fs.readdir(dir, { withFileTypes: true });
const files = await Promise.all(
dirents.map((dirent) => {
const res = path.resolve(dir, dirent.name);
return dirent.isDirectory() ? getFiles(res) : res;
})
);
return Array.prototype.concat(...files);
}
const files = (await getFiles(s3Path)) as string[];
const uploads = files.map((filePath) =>
s3
.putObject({
Key: path.relative(s3Path, filePath),
Bucket: bucketName,
Body: createReadStream(filePath),
})
.promise()
);
return Promise.all(uploads);
}
await uploadDir(path.resolve('./my-path'), 'bucketname');
前几天我只是在考虑这个问题，并在想这样的事情：
...
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);
});
您可以尝试node-s3-client。
从同步目录到 s3文档：
更新：添加了客户端初始化代码。
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");
});
这是一个在上传方法上包含 Promise 的版本。此版本允许您在所有上传完成后执行操作Promise.all().then...
const path = require('path');
const fs = require('fs');
const AWS = require('aws-sdk');
const s3 = new AWS.S3();
const directoryToUpload = 'directory-name-here';
const bucketName = 'name-of-s3-bucket-here';
// get file paths
const filePaths = [];
const getFilePaths = (dir) => {
fs.readdirSync(dir).forEach(function (name) {
const filePath = path.join(dir, name);
const stat = fs.statSync(filePath);
if (stat.isFile()) {
filePaths.push(filePath);
} else if (stat.isDirectory()) {
getFilePaths(filePath);
}
});
};
getFilePaths(directoryToUpload);
// upload to S3
const uploadToS3 = (dir, path) => {
return new Promise((resolve, reject) => {
const key = path.split(`${dir}/`)[1];
const params = {
Bucket: bucketName,
Key: key,
Body: fs.readFileSync(path),
};
s3.putObject(params, (err) => {
if (err) {
reject(err);
} else {
console.log(`uploaded ${params.Key} to ${params.Bucket}`);
resolve(path);
}
});
});
};
const uploadPromises = filePaths.map((path) =>
uploadToS3(directoryToUpload, path)
);
Promise.all(uploadPromises)
.then((result) => {
console.log('uploads complete');
console.log(result);
})
.catch((err) => console.error(err));
这对我有用（你需要添加 walkSync 包）：
async function asyncForEach(array, callback) {
for (let index = 0; index < array.length; index++) {
await callback(array[index], index, array);
}
}
const syncS3Directory = async (s3Path, endpoint) => {
await asyncForEach(walkSync(s3Path, {directories: false}), async (file) => {
const filePath = Path.join(s3Path, file);
const fileContent = fs.readFileSync(filePath);
const params = {
Bucket: endpoint,
Key: file,
Body: fileContent,
ContentType: "text/html",
};
let s3Upload = await s3.upload(params).promise();
s3Upload ? undefined : Logger.error("Error synchronizing the bucket");
});
console.log("S3 bucket synchronized!");
};
const AWS = require("aws-sdk");
const fs = require("fs");
const path = require("path");
const async = require("async");
const readdir = require("recursive-readdir");
// AWS CRED
const ID = "<accessKeyId>";
const SECRET = "<secretAccessKey>";
const rootFolder = path.resolve(__dirname, "../");
const uploadFolder = "./sources";
// The name of the bucket that you have created
const BUCKET_NAME = "<Bucket_Name>";
const s3 = new AWS.S3({
accessKeyId: ID,
secretAccessKey: SECRET
});
function getFiles(dirPath) {
return fs.existsSync(dirPath) ? readdir(dirPath) : [];
}
async function uploadToS3(uploadPath) {
const filesToUpload = await getFiles(path.resolve(rootFolder, uploadPath));
console.log(filesToUpload);
return new Promise((resolve, reject) => {
async.eachOfLimit(
filesToUpload,
10,
async.asyncify(async file => {
const Key = file.replace(`${rootFolder}/`, "");
console.log(`uploading: [${Key}]`);
return new Promise((res, rej) => {
s3.upload(
{
Key,
Bucket: BUCKET_NAME,
Body: fs.readFileSync(file)
},
err => {
if (err) {
return rej(new Error(err));
}
res({ result: true });
}
);
});
}),
err => {
if (err) {
return reject(new Error(err));
}
resolve({ result: true });
}
);
});
}
uploadToS3(uploadFolder)
.then(() => {
console.log("upload complete!");
process.exit(0);
})
.catch(err => {
console.error(err.message);
process.exit(1);
});
