Question

制作了一个蚊帐(6.0)复印件,读出亚马孙S3 Bucket和Zp文档中的文档,然后通过ZipStream下载。

We have made use of the following method to zip files on fly. Reference : Blog

[HttpGet]
        public async Task ZipAFileS3()
        {
            var s3Keys = this.ListFiles();
            var bucketname = "myBucket";

            Response.ContentType = "application/octet-stream";
            Response.Headers.Add("Content-Disposition", "attachment; filename="files.zip"");

            using (var s3 = CreateS3Client())
            {
                using (var archive = new ZipArchive(Response.BodyWriter.AsStream(), ZipArchiveMode.Create))
                {
                    foreach (var s3Key in s3Keys)
                    {
                        var entry = archive.CreateEntry(Path.GetFileName(s3Key), CompressionLevel.NoCompression);
                        using (var entryStream = entry.Open())
                        {
                            var request = new GetObjectRequest { BucketName = bucketname, Key = s3Key };
                            using (var getObjectResponse = await s3.GetObjectAsync(request))
                            {
                                await getObjectResponse.ResponseStream.CopyToAsync(entryStream);
                            }
                        }
                    }
                }
            }
        }


    public static AmazonS3Client CreateS3Client()
        {
                var AWSAccessKeyId = "";
                var AWSSecretAccessKey = "";
                var Token = "";
                var awsCredentials = new SessionAWSCredentials(AWSAccessKeyId, AWSSecretAccessKey, Token);
                return new AmazonS3Client(awsCredentials, RegionEndpoint.EUWest1);
        }

该台在测试时,高效地在IIS和Nginx服务器上运行。当地和爱心的Beanstalk, 单一症状。

a在<> 甲壳体与Load Balancer相配。流落在Failed——网络错误的后面,同时正转交齐p文档。

我还检查了云层监测的标志,以核实这一错误是否来自申请方。我看到,即使在与客户的联系关闭之后,档案传送也在进行。

不能肯定的是,造成这一问题的原因是什么。

Proxy Server : Nginx

下面是Nginx配置,在出现新情况时加以修改。
