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。
