查找Python示例以搜索Cognito标识并更新属性

import boto3

# 创建Cognito身份验证客户端
client = boto3.client('cognito-idp', region_name='your_region')

# 搜索Cognito标识
def search_cognito_identity(email):
    # 根据邮箱地址查找用户
    response = client.list_users(
        UserPoolId='your_user_pool_id',
        AttributesToGet=['sub'],  # 获取用户的Cognito标识
        Filter='email = "{}"'.format(email)
    )
    
    # 检查是否找到匹配的用户
    if response['Users']:
        return response['Users'][0]['Username']  # 返回用户的Cognito标识
    else:
        return None

# 更新Cognito标识的属性
def update_cognito_attribute(identity, attribute_name, attribute_value):
    response = client.admin_update_user_attributes(
        UserPoolId='your_user_pool_id',

                'Value': attribute_value
            },
        ]
    )
    
    # 检查更新是否成功
    if response['ResponseMetadata']['HTTPStatusCode'] == 200:
        return True
    else:
        return False

# 使用示例
