创建实例示例

本章节对创建实例AK/SK方式使用SDK进行示例说明。

创建实例示例代码只需将AK/SK信息替换为实际AK/SK，代码中可以使用初始化CreateInstanceReq中的Name和Model配置实例的名称和模型，配置完成后运行即可。

1. 创建实例调用示例代码如下：

   using System; 
   using System.Collections.Generic; 
   using HuaweiCloud.SDK.Core;
   using HuaweiCloud.SDK.Core.Auth;
   using HuaweiCloud.SDK.ImageSearch;
   using HuaweiCloud.SDK.ImageSearch.V1;
   using HuaweiCloud.SDK.ImageSearch.V1.Model;
   using Newtonsoft.Json;
    
   namespace RunCreateInstanceSolution
   {
       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 RunCreateInstanceRequest
               {
               };
             req.Body = new CreateInstanceReq()
             {
                Name = "instance-name",
                Model = "common-search",
                Tags = new List<string>{"animal", "plant"}
             };
    
               try
               {
                   var resp = client.RunCreateInstance(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，控制台返回200即表示程序执行成功。创建实例结果输出到控制台。

   200 
   {
     "instanceName": "instance-name",
     "level": 30000000,
     "expiredDate": -1,
     "domain": "通用图片搜索",
     "desc": "",
     "registerDate": 1638939677331,
     "tags"[
       "animal",
       "plant"
     ],
     "status": "NORMAL"
   }
