创建用户

您可以使用 CreateUser 操作使用您提供的唯一用户 ID 在集合中创建新用户。然后，您可以将多张人脸与新创建的用户相关联。

创建用户 (SDK)

1. 如果您尚未执行以下操作，请：

   1. 使用 AmazonRekognitionFullAccess 权限创建或更新 IAM 用户。有关更多信息，请参阅 步骤 1：设置 AWS 账户并创建用户。

   2. 安装并配置 AWS CLI 和 AWS SDK。有关更多信息，请参阅 步骤 2：设置 AWS CLI 和 AWS SDK。

2. 使用以下示例调用 CreateUser 操作。

   Java

   此 Java 代码示例创建了一名用户。

   import com.amazonaws.services.rekognition.AmazonRekognition;
   import com.amazonaws.services.rekognition.AmazonRekognitionClientBuilder;
   import com.amazonaws.services.rekognition.model.CreateUserRequest;
   import com.amazonaws.services.rekognition.model.CreateUserResult;
   
   
   public class CreateUser {
   
       public static void main(String[] args) throws Exception {
   
   
           AmazonRekognition rekognitionClient = AmazonRekognitionClientBuilder.defaultClient();
   
           //Replace collectionId and userId with the name of the user that you want to create in that target collection.
   
           String collectionId = "MyCollection";
           String userId = "demoUser";
           System.out.println("Creating new user: " +
                   userId);
   
           CreateUserRequest request = new CreateUserRequest()
                   .withCollectionId(collectionId)
                   .withUserId(userId);
   
           rekognitionClient.createUser(request);
       }
   
   }

   AWS CLI

   AWS CLI 命令使用 create-user CLI 操作创建了一名用户。

   aws rekognition create-user --user-id user-id --collection-id collection-name --region region-name
   --client-request-token request-token

   Python

   此 Python 代码示例创建了一名用户。

       try:

           client.create_user(

       create_user(collection_id, user_id)

   Go

   此 Go 代码示例使用 AWS Go SDK V2 创建了一名用户。

   
   package main
   
   import (
   	"context"
   	"fmt"
   	"log"
   
   	"github.com/aws/aws-sdk-go-v2/aws"
   	"github.com/aws/aws-sdk-go-v2/config"
   	"github.com/aws/aws-sdk-go-v2/service/rekognition"
   )
   
   func main() {
   	// Load the AWS SDK configuration
   	cfg, err := config.LoadDefaultConfig(context.TODO(), config.WithRegion("us-west-2"))
   	if err != nil {
   		log.Fatalf("Failed to load configuration: %v", err)
   	}
   
   	// Create a Rekognition client
   	client := rekognition.NewFromConfig(cfg)
   
   	// Set up the input parameters
   	input := &rekognition.CreateUserInput{
   		CollectionId: aws.String("my-new-collection"), // Replace with your collection ID
   		UserId:       aws.String("user12345678910"),   // Replace with desired user ID
   	}
   
   	// Call the CreateUser operation
   	result, err := client.CreateUser(context.TODO(), input)
   	if err != nil {
   		log.Fatalf("Failed to create user: %v", err)
   	}
   
   	// Print out the results
   	fmt.Printf("User created successfully:\n")
   
   }
