This section describes how to query an image using AK/SK authentication.

Replace the AK/SK in the sample code with the actual AK/SK. Set the Path parameter in the initialized DeletePictureRequestReq command to specify the URL of the image you want to query. After the configuration is complete, run the code.

The sample code for querying an image is as follows:

package main
 
import (
    "fmt"
    "github.com/huaweicloud/huaweicloud-sdk-go-v3/core/auth/basic"
    imagesearch "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/imagesearch/v1"
    "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/imagesearch/v1/model"
    region "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/imagesearch/v1/region"
)
 
func main() {
// Set the obtained AK and SK.
    ak := "<YOUR AK>"
    sk := "<YOUR SK>"
 
    auth := basic.NewCredentialsBuilder().
        WithAk(ak).
        WithSk(sk).
        Build()
    // Set the request client. In this example, CN North-Beijing4 is used.
    client := imagesearch.NewImageSearchClient(
        imagesearch.ImagesearchClientBuilder().
            WithRegion(region.ValueOf("cn-north-4")).
            WithCredential(auth).
            Build())
    // Set the instance name.
    request := &model.RunCheckPictureRequest{
        InstanceName: "instance-name",
    }
    //Set the image URL.
    path := "https://bucketname.obs.cn-north-4.myhuaweicloud.com/imagesearch/test.jpg"
    request.Body = &model.DeletePictureReq{
        Path: &path,
    }
    response, err := client.RunCheckPicture(request)
    if err == nil {
        fmt.Printf("%+v\n", response)
    } else {
        fmt.Println(err)
    }
}

Execute the sample code. If the image query result is displayed on the console, the code is successfully executed. For details, see Querying an Image.
