图像标签示例

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。

                     },

                 }  
             ]
