我在尝试将文件上传到S3存储桶时遇到了问题.除了我的文件参数看起来不合适之外,一切都有效.我正在使用Amazon S3 sdk从nodejs上传到s3.

这些是我的路线设置:

var multiparty = require('connect-multiparty'),
    multipartyMiddleware = multiparty();
app.route('/api/items/upload').post(multipartyMiddleware, items.upload);

这是items.upload()函数:

exports.upload = function(req, res) {
    var file = req.files.file;
    var s3bucket = new AWS.S3({params: {Bucket: 'mybucketname'}});
    s3bucket.createBucket(function() {
        var params = {
            Key: file.name,
            Body: file
        };
        s3bucket.upload(params, function(err, data) {
            console.log("PRINT FILE:", file);
            if (err) {
                console.log('ERROR MSG: ', err);
            } else {
                console.log('Successfully uploaded data');
            }
        });
    });
};

将Bodyparam 设置为字符串就"hello"可以了.根据doc,Bodyparam必须采用 (Buffer,Typed Array,Blob,String,ReadableStream)对象数据.但是,上载文件对象失败,并显示以下错误消息:
