Querying an Image

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 DeletePictureReq class to specify the URL of the image you want to query. After the configuration is complete, run the code.

  1. The sample code for querying an image is as follows:
    using System; 
    using System;
    using System.Collections.Generic;
    using HuaweiCloud.SDK.Core;
    using HuaweiCloud.SDK.Core.Auth;
    using HuaweiCloud.SDK.ImageSearch;
    using HuaweiCloud.SDK.ImageSearch.V1;
    using HuaweiCloud.SDK.ImageSearch.V1.Model;
    using Newtonsoft.Json;
     
    namespace RunCheckPictureSolution
    {
        class Program
        {
            static void Main(string[] args)
            {
                const string ak = "<YOUR AK>";
                const string sk = "<YOUR SK>";
     
                var config = HttpConfig.GetDefaultConfig();
                config.IgnoreSslVerification = true;
                var auth = new BasicCredentials(ak, sk);
     
                var client = ImageSearchClient.NewBuilder()
                        .WithCredential(auth)
                        .WithRegion(ImageSearchRegion.ValueOf("cn-north-4"))
                        .WithHttpConfig(config)
                        .Build();
     
                var req = new RunCheckPictureRequest
                {
                    InstanceName = "instance-name"
                };
                req.Body = new DeletePictureReq()
                {
                    Path = "https://bucketname.obs.cn-north-4.myhuaweicloud.com/imagesearch/test.jpg"
                };
     
                try
                {
                    var resp = client.RunCheckPicture(req);
                    var respStatusCode = resp.HttpStatusCode;
                    Console.WriteLine(respStatusCode);
                    Console.WriteLine(JsonConvert.DeserializeObject(resp.HttpBody));
                }
                catch (RequestTimeoutException requestTimeoutException)
                {
                    Console.WriteLine(requestTimeoutException.ErrorMessage);
                }
                catch (ServiceResponseException clientRequestException)
                {
                    Console.WriteLine(clientRequestException.HttpStatusCode);
                    Console.WriteLine(clientRequestException.ErrorCode);
                    Console.WriteLine(clientRequestException.ErrorMsg);
                }
                catch (ConnectionException connectionException)
                {
                    Console.WriteLine(connectionException.ErrorMessage);
                }
            }
        }
    }
  2. 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.
