如何在给定主键列表的情况下使用boto3对DynamoDB运行批处理查询

import boto3
from boto3.dynamodb.conditions import Key

dynamodb = boto3.client('dynamodb')

table_name = 'your_table_name'

primary_keys = ['key1', 'key2', 'key3']

keys_to_get = []
for key in primary_keys:
    keys_to_get.append({'your_primary_key_name': {'S': key}})

batch_get_request = {
    'RequestItems': {
        table_name: {
            'Keys': keys_to_get
        }
    }
}

response = dynamodb.batch_get_item(**batch_get_request)

if 'Responses' in response:
    items = response['Responses'][table_name]
    for item in items:
        # 处理每个查询结果
        print(item)
else:
    print('未找到匹配的项')
