查询图片示例

本章节对查询图片AK/SK方式使用SDK进行示例说明。

查询图片示例代码只需将AK/SK信息替换为实际AK/SK，代码中可以使用DeletePictureReq类的Path配置图片的URL，配置完成后运行即可。

1. 查询图片调用示例代码如下：

   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)
           {
           //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 = 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. 执行示例代码文件，控制台输出查询图片结果即表示程序执行成功。查询图片结果输出到控制台。
