将文件上载到Amazon S3中的存储桶失败并显示“达到最大重试次数”

我一直在尝试使用他们的.net SDK创建存储桶并将文件上传到Amazon S3。 我能够创建存储桶并指定它们是在欧盟地区创建的。 用于创建存储桶的代码如下所示

PutBucketRequest request = new PutBucketRequest(); request.WithBucketName(bucketName) .WithBucketRegion(S3Region.EU); client.PutBucket(request); 

然后，我使用以下代码继续将文件上传到存储桶：

 PutObjectRequest request = new PutObjectRequest(); request.WithBucketName(bucketName) .WithCannedACL(S3CannedACL.PublicRead) .WithKey(remoteFileName) .WithInputStream(uploadFileStream); 

文件上载代码失败，并显示错误“达到最大重试次数”。

任何人都可以让我知道我需要做什么才能使上传工作？

谢谢。

编辑：尝试使用AWS管理控制台将文件上传到同一个存储桶工作正常。

我终于找到了这个问题。

在特定区域中定位存储区时，必须将Amazon S3客户端对象配置为使用特定端点。 配置端点的代码与构造函数中的一样，客户端的创建位于下面类的各个方法中：

 public class AmazonS3Service : IAmazonS3Service { private AmazonS3 client; private string accessKeyID; private string secretAccessKeyID; private AmazonS3Config config; public AmazonS3Service() { accessKeyID = ConfigurationManager.AppSettings["AWSAccessKey"]; secretAccessKeyID = ConfigurationManager.AppSettings["AWSSecretKey"]; config = new AmazonS3Config(); config.ServiceURL = ConfigurationManager.AppSettings["AWSEUEndPoint"]; } public void CreateBucket(string bucketName) { using (client = Amazon.AWSClientFactory.CreateAmazonS3Client(accessKeyID, secretAccessKeyID, config)) { try { PutBucketRequest request = new PutBucketRequest(); request.WithBucketName(bucketName) .WithBucketRegion(S3Region.EU); client.PutBucket(request); } catch (AmazonS3Exception amazonS3Exception) { if (amazonS3Exception.ErrorCode != null && (amazonS3Exception.ErrorCode.Equals("InvalidAccessKeyId") || amazonS3Exception.ErrorCode.Equals("InvalidSecurity"))) { //log exception - ("Please check the provided AWS Credentials."); } else { //log exception - ("An Error, number {0}, occurred when creating a bucket with the message '{1}", amazonS3Exception.ErrorCode, amazonS3Exception.Message); } } } } public void UploadFile(string bucketName, Stream uploadFileStream, string remoteFileName) { using (client = Amazon.AWSClientFactory.CreateAmazonS3Client(accessKeyID, secretAccessKeyID, config)) { try { PutObjectRequest request = new PutObjectRequest(); request.WithBucketName(bucketName) .WithCannedACL(S3CannedACL.PublicRead) .WithKey(remoteFileName) .WithInputStream(uploadFileStream); using (S3Response response = client.PutObject(request)) { WebHeaderCollection headers = response.Headers; foreach (string key in headers.Keys) { //log headers ("Response Header: {0}, Value: {1}", key, headers.Get(key)); } } } catch (AmazonS3Exception amazonS3Exception) { if (amazonS3Exception.ErrorCode != null && (amazonS3Exception.ErrorCode.Equals("InvalidAccessKeyId") || amazonS3Exception.ErrorCode.Equals("InvalidSecurity"))) { //log exception - ("Please check the provided AWS Credentials."); } else { //log exception -("An error occurred with the message '{0}' when writing an object", amazonS3Exception.Message); } } } } }
