我目前正在尝试使用aws-sdk和gulp将网站的资产上传到amazon s3,但是现在我只是使用以下代码上传单个文件：

gulp.task('publish', function() {
    var AWS = require('aws-sdk'),
        fs = require('fs');

    AWS.config.accessKeyId = 'access_id';
    AWS.config.secretAccessKey = 'secret_key';
    AWS.config.region = 'eu-central-1';
    var fileStream = fs.createReadStream('folder/filename');
    fileStream.on('error', function (err) {
            if (err) { throw err; }
        });
    fileStream.on('open', function () {
    var s3 = new AWS.S3();
            s3.putObject({
                    Bucket: 'bucket_name',
                        Key: 'assets/filename',
                        Body: fileStream,
                        ACL:'public-read'
                        }, function (err) {
        if (err) { throw err; }
        else { console.log("Upload successfull"); }
                });
        });
});

由于我既不是node.js也不是JS dev,我不知道如何将所有资产上传到S3的文件夹资产中.

理想情况下,应用我用来上传一个文件的操作,但对于每个文件都会很整洁.这怎么可行？

解决方法:

找到解决我问题的方法.使用此代码,我最终设法使用正确的ACL将我的所有资产上传到我的存储桶.希望这可以帮助人们不要花太多时间在这样一个愚蠢的问题上.
