Question

我正在尝试使AWS Rekognition与通过Active Storage存储在S3中的照片一起用于Rails 6 rc3。

Aws.config.update({
      region: 'us-west-2',
      credentials: Aws::Credentials.new(Rails.application.credentials.aws[:access_key], Rails.application.credentials.aws[:secret_access_key])
    })

    rekognition = Aws::Rekognition::Client.new(region: Aws.config[:region], credentials: Aws.config[:credentials])
    @uri = @user.avatar.service_url
    @dir = @uri.split("/").fourth
    @key = @dir.split("?").first

    response = rekognition.detect_labels(
      {image:
        {s3_object:
          {bucket: 'bucket',
            name: @key,
          },
        },
        max_labels: 5,
        min_confidence: 70
      }
    )
    puts response
    @user.update(notes: response)

但是响应中的标签显示为“已过滤”

{:labels=>[{:name=>"[FILTERED]", :confidence=>99.28252410888672, :instances=>[], :parents=>[{:name=>"[FILTERED]"}

在aws-cli上执行相同的操作会显示标签。为什么它显示“已过滤”，我如何显示标签？

Answer 1

如果要查看未过滤的标签，请遍历response对象并打印标签字段：

response.labels.each { |label| puts(label.name) }

Rails Active Storage + AWS Rekognition detect_labels：过滤后的标签
