    This document provides an overview of APIs and SDK code samples for image moderation.
    API
    Description
    Scans existing data stored in COS for porn, illegal, and advertising images.
    Moderates multiple images in batches.
    Queries the result of specified image moderation job.

    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.

    Method prototype

    CosResult GetImageAuditing(const GetImageAuditingReq& req, GetImageAuditingResp* resp);

    Sample request

    qcloud_cos::CosConfig config("./config.json");
    qcloud_cos::CosAPI cos(config);
    std::string bucket_name = "examplebucket-1250000000";
    std::string object_name = "test.jpg";
    
    GetImageAuditingReq req(bucket_name);
    GetImageAuditingResp resp;
    
    // Add request parameters as detailed in the API documentation
    req.SetObjectKey(object_name);
    req.SetBizType("b81d45f94b91a683255e9a9506f45a11");
    // req.SetDetectType("Porn,Ads");
    
    // Call the API to get the job response object
    CosResult result = cos.GetImageAuditing(req, &resp);
    if (result.IsSucc()) {
    // If the moderation job is created successfully, you can call the member functions of `GetImageAuditingResp`.
    } else {
    // If the moderation job failed to be created, you can call the member functions of `CosResult` to output the error message.
    }

    void SetDetectType(const std::string& detect_type);
    // URL of the image to be moderated, which can be a URL of any image accessible over the public network.
    // If `detect-url` is set, moderation will be conducted by `detect-url` by default, and there will be no need to enter `ObjectKey`.
    // If `detect-url` is not set, moderation will be conducted by `ObjectKey` by default.

    // Get the job details returned by the API request
    ImageAuditingJobsDetail GetJobsDetail();
    // Get the `RequestId` returned by the API
    std::string GetRequestId();

    Response description

    Success: The moderation job result in the XML content returned by the API will be parsed into the ImageAuditingJobsDetail structure. For specific response parameters, see Single Image Moderation.
    Failure: If an error (for example, the bucket does not exist) occurs, the error message will be parsed into the CosResult structure. For more information, see Troubleshooting.

    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.

    Method prototype

    std::string object_name_b = "test2.jpg";
    
    BatchImageAuditingReq req(bucket_name);
    BatchImageAuditingResp resp;
    
    // input 1
    AuditingInput input_a = AuditingInput();
    input_a.SetObject(object_name_a);
    req.AddInput(input_a);
    
    // input2
    AuditingInput input_b = AuditingInput();
    input_a.SetObject(object_name_b);
    req.AddInput(input_b);
    
    // Moderation configuration
    req.SetBizType("b81d45f94b91a683255e9a9506f45a11");
    // req.SetDetectType("Porn,Ads");
    
    // Call the API to get the job response object
    CosResult result = cos.BatchImageAuditing(req, &resp);
    if (result.IsSucc()) {
    // If the moderation job is created successfully, you can call the member functions of `BatchImageAuditingResp`.
    } else {
    // If the moderation job failed to be created, you can call the member functions of `CosResult` to output the error message.
