图像识别 IMAGE-主体识别示例

主体识别示例本章节对主体识别AK/SK方式使用SDK进行示例说明。主体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ImageMainObjectDetectionReq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。主体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 RunImageMainObjectDetectionSolution { 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 RunImageMainObjectDetectionRequest { }; req.Body = new ImageMainObjectDetectionReq() { Threshold = 30, Url = "https://XXX.jpg" //替换为公网可以访问的图片地址 }; try { var resp = client.RunImageMainObjectDetection(req); var respStatusCode = resp.HttpStatusCode; Console.WriteLine(respStatusCode); } 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); } } } } 执行示例代码文件，控制台输出主体识别结果即表示程序执行成功。相关参数说明请参考主体识别API。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 { "result": [{ "confidence": "95.73", "label": "bounding_box", "location": { "height": 327.77, "top_left_x": 3.7, "top_left_y": 1.72, "width": 463.03}}, { "confidence": "88.35", "label": "main_object_box", "location": { "height": 328.35, "top_left_x": 3.22, "top_left_y": 1.5, "width": 456.63} }] } 父主题：使用SDK（.NET）

图像搜索 IMAGESEARCH-检查数据示例

检查数据示例本章节对检查数据AK/SK方式使用SDK进行示例说明。检查数据示例代码只需将AK/SK信息替换为实际AK/SK，代码中可以使用CheckParam中的ItemId参数配置数据的服务实例级唯一标识，配置完成后运行即可。更新数据调用示例代码如下： using System; using System.Collections.Generic; using HuaweiCloud.SDK.Core; using HuaweiCloud.SDK.Core.Auth; using HuaweiCloud.SDK.ImageSearch; using HuaweiCloud.SDK.ImageSearch.V2; using HuaweiCloud.SDK.ImageSearch.V2.Model; namespace RunCheckDataSolution { 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); const string iamEndpoint = "https://iam.cn-north-4.myhuaweicloud.com"; const string endpoint = "https://mms.cn-north-4.myhuaweicloud.com"; const string projectId = "project_id"; var config = HttpConfig.GetDefaultConfig(); config.IgnoreSslVerification = true; var auth = new BasicCredentials(ak, sk, projectId).WithIamEndpoint(iamEndpoint); // 初始化客户端 var client = ImageSearchClient.NewBuilder() .WithCredential(auth) // 设置region, 示例中为北京四 .WithRegion(new Region("cn-north-4", endpoint)) .WithHttpConfig(config) .Build(); var req = new RunCheckDataRequest { ServiceName = "service_name" }; req.Body = new CheckParam() { ItemId = "item_id" }; try { var resp = client.RunCheckData(req); var respStatusCode = resp.HttpStatusCode; Console.WriteLine(respStatusCode); } 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); } } } } 执行示例代码文件，控制台输出检查数据结果即表示程序执行成功。 200 { "result": "success", "data": { "existed": true, "item_info": { "custom_tags": { "key": "value" }, "custom_num_tags": { "key": value } } } } 父主题：使用SDK（.NET）
