      Overview

      This document describes how to use the content moderation feature provided by Cloud Infinite (CI). CI fully integrates the processing capabilities with the COS SDK.
      Note:
      To use the content moderation service, you need to have the permission to use CI:
      For root accounts, click here for role authorization.
      For sub-accounts, see Authorizing Sub-Accounts to Access CI Services.
      This document provides an overview of APIs and SDK code samples for image moderation.
      API
      Description
      Leverages CI's content moderation API to scan existing data stored in COS for porn, illegal, and advertising images.

      Single image moderation

      Feature description

      The existing data scan feature of image moderation leverages CI's persistent processing API to scan existing data stored in COS for porn, illegal, and advertising images. Image moderation requests are GET requests.

      Method prototype

      // Basic operations
      func (s *CIService) ImageRecognition(ctx context.Context, name string, DetectType string) (*ImageRecognitionResult, *Response, error)
      // You can specify more parameters.
      func (s *CIService) ImageAuditing(ctx context.Context, name string, opt *ImageRecognitionOptions) (*ImageRecognitionResult, *Response, error)

      Sample request

      DetectType := "porn,ads"
      name := "test.jpg"
      res, _, err := c.CI.ImageRecognition(context.Background(), name, DetectType)
      
      
      opt := &cos.ImageRecognitionOptions{
          CIProcess: "sensitive-content-recognition",
          DetectType: "porn,ads",
          DetectUrl:   "http://www.example.com/test.jpg",
          BizType:     "ce25f391a72e11eb99f********",
      }
      res, _, err := c.CI.ImageAuditing(context.Background(), "", opt)

      Parameter description

      type ImageRecognitionOptions struct {
          CIProcess        string
          DetectType       string
          DetectUrl        string
          Interval         int
          MaxFrames        int
          BizType          string
          LargeImageDetect int
          DataId           string
          Async            int
          Callback         string
      }
      Parameter
      Description
      Type
      Required
      name
      Name of the image file in the COS bucket. The COS bucket is specified by Host. For example, if the file is img.jpg in the test directory in the examplebucket-1250000000 bucket in Beijing, then Host is examplebucket-1250000000.cos.ap-beijing.myqcloud.com, and ObjectKey is test/img.jpg. If the ImageAuditing API is used to moderate an image URL, pass in an empty string.
      String
      Yes
      CIProcess
      This field identifies the data processing feature, which is sensitive-content-recognition for content moderation.
      String
      Yes
      BizType
      Moderation policy. If this parameter is not specified, the default policy will be used. The policy can be configured in the console. For more information, see Setting Moderation Policy.
      String
      No
      DetectType
      Moderation type, such as porn (pornography) and ads (advertising). You can select multiple types; for example, detect-type=porn,ads indicates to moderate the image for porn and advertising information. If you need to moderate more scenes, use the BizType parameter.
      String
      No
      DetectUrl
      You can enter a detect-url value to moderate an image accessible over the public network. If detect-url is not specified, the backend will moderate by ObjectKey by default. If detect-url is specified, the backend will moderate by detect-url, and there will be no need to enter ObjectKey. Sample detect-url: http://www.example.com/abc.jpg.
      String
      No
      Interval
      For GIF image moderation, you can use this parameter to configure the frame capturing interval. The default value is 5, indicating to capture a frame every five frames starting from the first frame (included).
      Integer
      No
      MaxFrames
      The maximum number of frames to be captured for GIF image moderation, which must be greater than 0. The default value is 5, indicating to capture five frames at most.
      Integer
      No
      LargeImageDetect
      Whether to compress the image that exceeds the size limit before moderation. Valid values: 0 (no), 1 (yes). Default value: 0. Note: Images up to 32 MB in size can be compressed, and image compression fees will be charged. For large animated images such as GIF, the compression time is long, which may cause the moderation to fail due to timeout.
      Integer
      No
      DataId
      Image ID. This field will return the original content in the result, which can contain up to 512 bytes.
      String
      No
      Async
      Whether to moderate asynchronously. Valid values: 0 (returns the result synchronously); 1 (moderates asynchronously). Default value: 0.
      String
      No
      Callback
      The moderation result (in Detail mode) can be sent to your callback address in the form of a callback. This parameter takes effect for async moderation. Addresses starting with http:// or https:// are supported, such as http://www.callback.com.
      String
      No

      Response description

      Calling the ImageRecognition or ImageAuditing function will parse the XML content returned by the API into the ImageRecognitionResult structure. For specific response parameters, see Single Image Moderation.

      Batch image moderation

      Feature description

      The batch image moderation API adopts a sync POST request method. You can use this API to perform content moderation on multiple image files.

      // For CI jobs, you need to provide the CIURL.
      bu, _ := url.Parse("https://examplebucket-1250000000.cos.COS_REGION.myqcloud.com")
      cu, _ := url.Parse("https://examplebucket-1250000000.ci.COS_REGION.myqcloud.com")
      b := &cos.BaseURL{BucketURL: bu, CIURL: cu}
      c := cos.NewClient(b, &http.Client{
