Demo Project of Image Tagging

This section describes how to use the Image Tagging SDK by AK/SK authentication.

  • Replace the AK/SK in the sample code with the actual AK/SK. You can use either the url or image parameter in the initialized ImageTaggingReq to configure image information. This section uses url as an example.
  • endpoint indicates the regions and endpoints for HUAWEI CLOUD services. For details, see Regions and Endpoints.
  1. The sample code for calling Image Tagging is as follows:

    response, err := client.RunImageTagging(request)
    if err == nil {
        fmt.Printf("%+v\n", response)
    } else {

    }}
  2. If the recognition result is displayed on the console, the execution is successful. For details about related parameters, see Image Tagging APIs.
