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。
- 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 。
- 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) { //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-1")) //此处替换为您开通服务的区域 .WithHttpConfig(config) .Build(); var req = new RunImageTaggingRequest { }; req.Body = new ImageTaggingReq() { Limit = 50, Threshold = 95, Language = "zh", Url = "https://XXX.jpg" //此处替换为公网可以访问的图片地址 }; 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); } } } }
- 执行示例代码,控制台返回200即表示程序执行成功。相关参数说明请参考图像标签API。
