node.js - 带环回的 AWS 文件上传 : Failed to create a multipart upload on S3

Question

尝试使用 loopback-component-storage 将多个图像文件上传到 AWS

方法如下:

 Game.add = function(ctx,options,cb)
        {
               var status = ctx.req.query.status,
                defaultLangCode = ctx.req.query.defaultLangCode,
                nameEn = ctx.req.query.nameEn;

            var rec = new Object();
            rec.parentHouseId = houseId;
            rec.status = status;
            rec.defaultLangCode = defaultLangCode;
            rec.nameEn = nameEn;

            if(!options) options = {forceIframeTransport : true};
            ctx.req.params.container = 'common';
            Game.app.models.container.upload(ctx.req,ctx.result,options,function (err,fileObj) {
                if(err) {
                    cb(err);
                } else {
                    var fileInfo = fileObj.files.file[0];
                    console.log(fileInfo);
                }
            });
        };

和

Game.remoteMethod(
        'add',
        {
            http:{path: '/add', verb: 'post', status: 200, errorStatus: 400},
            accepts: [
                { arg: 'ctx', type: 'object', http: { source:'context' } },
                { arg: 'options', type: 'object', http:{ source: 'query'} }
            ],
            returns: {
                arg: 'fileObject', type: 'object', root: true
            }
        }
    );

我正在尝试在那里上传两个图像文件。发布数据/图像两次产生此错误:

第二个当然不同。

我尝试使用空的 options 对象，但没有成功。

欢迎任何类型的建议。提前致谢。

尝试使用不同的 key / key id，结果相同。以及如何获取上传文件的网址？那当然是在我可以成功上传图片之后 :p

Answer 1

尝试在 s3 存储桶(权限)策略 中为用户启用权限。您是否为运行代码的实例分配了角色？ (如果使用 EC2 作为您的工作站)

这应该是评论。但是，不幸的是我没有发表评论的特权。
