本章节对图像标签AK/SK方式使用SDK进行示例说明。

图像标签示例代码只需将AK/SK信息替换为实际AK/SK，代码中可以使用初始化ImageTaggingReq中的url或image配置图像信息（image和url参数二选一），示例中以url为例，配置完成后运行即可。

1. 图像标签调用示例代码如下：

   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)
           {
               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 = ImageClient.NewBuilder()
                       .WithCredential(auth)
                       .WithRegion(ImageRegion.ValueOf("cn-north-1"))
                       .WithHttpConfig(config)
                       .Build();
   
               var req = new RunImageTaggingRequest
               {
               };
               req.Body = new ImageTaggingReq()
               {
                   Limit = 50,
                   Threshold = 95,
                   Language = "zh",
                   Url = "https://sdk-obs-source-save.obs.cn-north-4.myhuaweicloud.com/tagging-normal.jpg"
               };
   
               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. 执行示例代码，控制台返回200即表示程序执行成功。图像标签识别结果输出到控制台。

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

   200 { "result": { "tags": [ { "confidence": "98.01", "type": "树", "tag": "树", "i18n_tag": { "zh": "树", "en": "Tree" }, "i18n_type": { "zh": "树", "en": "Tree" }, "instances": [ ] } ] } }
