亚马逊：Amazon.S3.AmazonS3Exception使用Xamarin上传图片

时间：2015-11-05 18:03:53

标签： c# amazon-s3 xamarin amazon

我们在我支持的项目（实验室版本）上使用旧版SDK for Amazon A3。现在我想更新来自亚马逊的所有SDK并使用Cognito进行身份验证，而不是像以前那样直接传递凭据。

我的应用程序在Xamarin android上运行，需要将照片上传到Amazon S3。

使用我从Xamarin Studio上的NuGet包库获得的AWSSDK，我的代码创建了AmazonS3Client：

var credentials = new CognitoAWSCredentials("my pool id", Amazon.RegionEndpoint.UEast1);

var config = new AmazonS3Config() { RegionEndpoint = Amazon.RegionEndpoint.USWest2, Timeout = TimeSpan.FromSeconds(30) };

this.s3Client = new AmazonS3Client(credentials, config);

使用S3客户端上传图片的代码：

var request = new PutObjectRequest();
request.AutoCloseStream = true;
request.BucketName = this.bucket;
request.FilePath = filePath;
request.Key = key;
request.ContentType = "image/jpg";

if (handler != null) 
{
    request.StreamTransferProgress += (object sender, Amazon.Runtime.StreamTransferProgressArgs e) =>
    {
        handler(e, pedidoLacre, key, fotoPlaca);
    };
}

var taskResponse = this.s3Client.PutObjectAsync(request);
Task.WaitAll(taskResponse);

if (taskResponse.Exception != null)
{
    throw taskResponse.Exception;
}

异常错误：

我们认为这里的重要细节是我们的S3桶位于US-WEST-2区域，而Cognito位于US-EAST-1。我们读到它并且它应该不是问题，但你永远不会知道。

修改 我们放弃了区域错误的可能性，因为我们在与S3客户端相同的区域上创建了一个新存储桶，并且Exception仍然存在。

答案 0 :(得分：0)

前一段时间，我找到了解决这个问题的方法。

我的解决方案是使用代码创建存储桶。

var response = this.s3Client.PutBucketAsync("example");

在Amazon S3中使用sdk for xamarin是一个问题。
