# 媒资图像标签示例
本章节对媒资图像标签AK/SK方式使用SDK进行示例说明。
- 媒资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ImageMediaTaggingReq中的url或image方法配置图像信息（image和url参数二选一），示例中以url为例，配置完成后运行即可。
- endpoint是华为云各服务应用区域和各服务的终端节点，详情请查看 [地区和终端节点](https://developer.huaweicloud.com/endpoint?Image)。
1. 媒资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;
   namespace RunImageMediaTaggingSolution
   {
       class Program
       {
           static void Main(string[] args)
           {
          //认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险，建议在配置文件或者环境变量中密文存放，使用时解密，确保安全
         //本示例以ak和sk保存在环境变量中来实现身份验证为例，运行本示例前请先在本地环境中设置环境变量HUAWEICLOUD_SDK_AK和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-4")) //此处替换为您开通服务的区域，详情请查看地区和终端节点.
                       .WithHttpConfig(config)
                       .Build();
               var req = new RunImageMediaTaggingRequest
               {
               };
               req.Body = new ImageMediaTaggingReq()
               {
                   Threshold = 10,
                   Language = "zh",
                   Url = "https://XXX.jpg" //此处替换为公网可以访问的图片地址
               };
               try
               {
                   var resp = client.RunImageMediaTagging(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. 执行示例代码文件，控制台输出媒资图像标签结果即表示程序执行成功。相关参数说明请参考[媒资图像标签API](https://support.huaweicloud.com/api-image/image_03_0048.html#section5)。
