Upload photo to s3

drpatience

I am attempting to upload an image to AWS s3 using Xamarin and experiencing this error:

System.ObjectDisposedException: Cannot access a disposed object.

Object name: 'System.Net.Sockets.NetworkStream'.

I've implemented as follows:

    public TransferUtility s3transferUtility;
    public AmazonS3Client s3Client;

    public AWSObject()
    {
    }

    public void setupAWSCredentials(){

        CognitoAWSCredentials credentials = new CognitoAWSCredentials(
            "eu-west-1:**", 
            RegionEndpoint.EUWest1
        );

        var config = new AmazonS3Config() { RegionEndpoint = Amazon.RegionEndpoint.EUWest1, Timeout = TimeSpan.FromSeconds(30), UseHttp = true };

        AWSConfigsS3.UseSignatureVersion4 = true;

        s3Client = new AmazonS3Client(credentials, config);
        this.s3transferUtility = new TransferUtility(s3Client);

    }

    public async Task UploadPhoto(string filename){

        try {

            var documentsPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
            var filePath = Path.Combine(documentsPath, filename);

            TransferUtilityUploadRequest request = new TransferUtilityUploadRequest{BucketName = "xamarinbucket",FilePath = filePath,Key = "photoOne.png",ContentType = "image/png"};

            CancellationToken cancellationToken = new CancellationToken();

            await this.s3transferUtility.UploadAsync(request, cancellationToken);

        } catch (AmazonS3Exception s3Exception) {

            System.Console.WriteLine(s3Exception.StackTrace);
        }
    }

The functions are called as follows:

AWSObject awsObject = new AWSObject();
awsObject.setupAWSCredentials();
Task.Run(()=> awsObject.UploadPhoto("photoOne.png"));

Any suggestions ?

Same problem here

same problem

I have fixed it, the problem was here
var s3Client = new AmazonS3Client(creds, RegionEndpoint.EUWest1);

I was using EUWest1 then I changed to RegionEndpoint.USEast1 and I got another error:
System.IO.IOException: Error writing request ---> System.Net.Sockets.SocketException: The socket has been shut down

Then I changed to RegionEndpoint.USEast2 and the error was fixed

I realize that my correct region was USEast2 in the url of my buckets that looks like this:

https://s3.console.aws.amazon.com/s3/home?region=us-east-2

At the end of the link you can see the region.

my code is this:

private TransferUtility transferUtility;

private async void SetupAsync(){


    BasicAWSCredentials creds = new BasicAWSCredentials("MYACCESSKEY",
                                                                    "MYSECRETKEY");


                var config = new TransferUtilityConfig();
                config.ConcurrentServiceRequests = 10;
                config.MinSizeBeforePartUpload = 16 * 1024 * 1024;

                var s3Client = new AmazonS3Client(creds, RegionEndpoint.EUWest1);
                ListBucketsResponse response = await s3Client.ListBucketsAsync();
                Console.WriteLine("Buckets owner - {0}", response.Owner.DisplayName);
                foreach (S3Bucket bucket in response.Buckets)
                {
                    Console.WriteLine("Bucket {0}, Created on {1}", bucket.BucketName, bucket.CreationDate);
                }

                transferUtility = new TransferUtility(s3Client, config);
            }

            public async void UploadFileAsync(string filePath, string bucketName){

                try
                {


                    await transferUtility.UploadAsync(
                        filePath,
                        bucketName
                    );
                }
                catch(Exception e){
                    Debug.WriteLine("AWSS3 upload file exception = " + e);
                }


            }

call first setupAsyncMethod then UploadFileAsync

I am using AWSSDK.S3 nuget plugin
