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:

   using System;
   using System.Collections.Generic;
   using HuaweiCloud.SDK.Core;
   using HuaweiCloud.SDK.Core.Auth;
   using HuaweiCloud.SDK.Image;
   using HuaweiCloud.SDK.Image.V2;
   using HuaweiCloud.SDK.Image.V2.Model;
   using Newtonsoft.Json;
   
   namespace RunImageTaggingSolution
   {
       class Program
       {
           static void Main(string[] args) {
          //Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK and store them in the configuration file or environment variables.
         //In this example, the AK and SK are stored in environment variables for identity authentication. Before running this example, configure environment variables HUAWEICLOUD_SDK_AK and HUAWEICLOUD_SDK_SK.
           string accessKey= Environment.GetEnvironmentVariable("HUAWEICLOUD_SDK_AK", EnvironmentVariableTarget.Machine);
           string secretKey= Environment.GetEnvironmentVariable("HUAWEICLOUD_SDK_SK", EnvironmentVariableTarget.Machine);
   
               var config = HttpConfig.GetDefaultConfig();
               config.IgnoreSslVerification = true;
               var auth = new BasicCredentials(ak, sk);
   
               var client = ImageClient.NewBuilder()
                       .WithCredential(auth)
                       .WithRegion(ImageRegion.ValueOf("cn-north-1"))  //Replace cn-north-1 with the region where you enable the service. For details, see Regions and Endpoints.
                       .WithHttpConfig(config)
                       .Build();
   
               var req = new RunImageTaggingRequest
               {
               };
               req.Body = new ImageTaggingReq()
               {
                   Limit = 50,
                   Threshold = 95,
                   Language = "zh",
                   Url = "https://XXX.jpg"    //Replace it with an image URL that can be accessed from the Internet.
               };
   
               try
               {
                   var resp = client.RunImageTagging(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 200 is displayed on the console, the code is successfully executed. For details about related parameters, see Image Tagging APIs.
