翻拍识别示例

本章节对翻拍识别AK/SK方式使用SDK进行示例说明。

  • 翻拍识别示例代码只需将AK/SK信息替换为实际AK/SK,代码中可以使用RunRecaptureDetectReq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
  1. 翻拍识别调用示例代码如下:
    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 RunRecaptureDetectSolution
    {
        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
                        .WithHttpConfig(config)
                        .Build();
     
                var req = new RunRecaptureDetectRequest
                {
                };
                req.Body = new RecaptureDetectReq()
                {
                    Threshold = 0,
                    Url = "https://bucketname.obs.cn-north-4.myhuaweicloud.com/image/test1.jpg"//替换为公网可以访问的图片地址
                };
     
                try
                {
                    var resp = client.RunRecaptureDetect(req);
                    var respStatusCode = resp.HttpStatusCode;
                    Console.WriteLine(respStatusCode); 
                      Console.WriteLine(resp.HttpBody);
                }
                catch (RequestTimeoutException requestTimeoutException)
                {
                    Console.WriteLine(requestTimeoutException.ErrorMessage);
                }
                catch (ServiceResponseException clientRequestException)
                {
                    Console.WriteLine(clientRequestException.HttpStatusCode);
                    Console.WriteLine(clientRequestException.RequestId);
                    Console.WriteLine(clientRequestException.ErrorCode);
                    Console.WriteLine(clientRequestException.ErrorMsg);
                }
                catch (ConnectionException connectionException)
                {
                    Console.WriteLine(connectionException.ErrorMessage);
                }
            }
        }
    }
  2. 执行示例代码文件,控制台输出翻拍识别结果即表示程序执行成功。
