Javascript 使用Gulp将资产上载到s3

我目前正在尝试使用aws sdk和gulp将网站的资产上载到amazon s3，但目前我仅使用以下代码实现了上载单个文件：

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"); }
                });
        });
});

因为我既不是node.js也不是js开发人员，所以我不知道如何将我的所有资产上传到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，但是对于每个文件都是整洁的。这怎么可能呢？

找到了解决我问题的方法。有了这段代码，我最终成功地用正确的ACL将我的所有资产上传到我的bucket中。希望这能帮助人们不要像我一样花那么多时间在这样一个愚蠢的问题上

                };

            };
        });

此解决方案将资产放入一个未命名的子文件夹中，其中包含资产文件夹。
