StackSpot Bucket S3

Componente projetado para padronizar a comunicação com a Amazon Simple Storage Service (S3) para aplicações .NET Core.

Versões suportadas

  • net5.0
  • net6.0

Uso

1. Adicione o pacote NuGet StackSpot.Bucket.S3 ao seu projeto.
dotnet add package StackSpot.Bucket.S3
2. Configure as variáveis.
  • RegionEndpoint - Endpoint regional que será utilizado para requisitar o S3 - Campo Obrigatório.

Você pode sobrescrever a configuração padrão adicionando a seção S3 em seu appsettings.json.

  "S3": {
      "RegionEndpoint": "sa-east-1"
  }
3. Adicione ao seu IServiceCollection via services.AddBucketS3() no Startup da aplicação ou Program tendo como parametro de entrada IConfiguration e IWebHostEnvironment.
services.AddBucketS3(Configuration);

Implementação

  • DeleteAsync - Remove a versão nula(se houver) de um objeto e insere um marcador de exclusão, tornando a versão mais recente do objeto. Em caso de não haver uma versão nula, nenum objeto é removido.
public class Service
{
    private readonly IBucketS3 _bucketS3;

    public Service(IBucketS3 bucketS3)
    {
        _bucketS3 = bucketS3;
    }
    
    public async Task DeleteAsync()
    {
        var bucket = new Common.Bucket()
        {
            BucketName = "bucket-test",
            Key = "bucket-key"
        };
        await _bucketS3.DeleteAsync(bucket);
    }
}
  • GetStreamAsync - Recupera um objeto.
public class Service
{
    private readonly IBucketS3 _bucketS3;

    public Service(IBucketS3 bucketS3)
    {
        _bucketS3 = bucketS3;
    }
    
    public async Task GetStreamAsync()
    {
        var bucket = new Common.Bucket()
        {
            BucketName = "bucket-test",
            Key = "bucket-key"
        };
        var stream = await _bucketS3.GetStreamAsync(bucket);
    }

    public async Task GetGenericStreamAsync()
    {
        var bucket = new Common.Bucket()
        {
            BucketName = "bucket-test",
            Key = "bucket-key"
        };
        Example example = await _bucketS3.GetStreamAsync<Example>(bucket, ContentType.Json);
    }
}
  • UploadAsync - Adiciona um objeto ao bucket.
public class Service
{
    private readonly IBucketS3 _bucketS3;

    public Service(IBucketS3 bucketS3)
    {
        _bucketS3 = bucketS3;
    }
    
    public async Task UploadAsync(Example example)
    {
        var bucket = new Common.Bucket()
        {
            BucketName = "bucket-test",
            Key = "bucket-key"
        };

        var str = JsonConvert.SerializeObject(example);
        byte[] byteArray = Encoding.UTF8.GetBytes(str);

        await _bucketS3.UploadAsync(bucket, byteArray, ContentType.Json);
    }

    public async Task UploadAsync(Example example)
    {
        var bucket = new Common.Bucket()
        {
            BucketName = "bucket-test",
            Key = "bucket-key"
        };

        var str = JsonConvert.SerializeObject(example);

        await _bucketS3.UploadAsync(bucket, str, ContentType.Json);
    }
}
4. Ambiente local
  • Esta etapa não é obrigatória.
  • Recomendamos, para o desenvolvimento local, a criação de um contâiner com a imagem do Localstack.
  • Para o funcionamento local você deve preencher a variável de ambiente LOCALSTACK_CUSTOM_SERVICE_URL com o valor da url do serviço. O valor padrão do localstack é http://localhost:4566.
  • Abaixo um exemplo de arquivo docker-compose com a criação do contâiner:
version: '2.1'

services:
  localstack:
    image: localstack/localstack
    ports:
      - "4566:4566"
    environment:
      - SERVICES=s3
      - AWS_DEFAULT_OUTPUT=json
      - DEFAULT_REGION=us-east-1

Após a criação do contâiner, crie um bucket para realizar os testes com o componente. Recomendamos que você tenha instalado em sua estação o AWS CLI. Abaixo um exemplo de comando para criação de um bucket:

aws --endpoint-url=http://localhost:4566  --region=sa-east-1 s3 mb s3://[NOME DO BUCKET]
