如何通过node sdk的唯一密钥策略在CosmosDB上强制使用唯一密钥？

const { CosmosClient } = require('@azure/cosmos');

// 连接配置
const endpoint = 'https://your-cosmos-db-endpoint.documents.azure.com:443/';
const key = 'your-primary-key';
const client = new CosmosClient({ endpoint, key });

// 数据库和集合信息
const databaseName = 'your-database-name';
const containerName = 'your-container-name';

async function createUniqueKey() {
  const database = client.database(databaseName);
  const container = database.container(containerName);

  // 定义唯一键
  const uniqueKeyPolicy = {
    uniqueKeys: [
      { paths: ['/email'] } // 单字段唯一键
      // 或者复合唯一键
      // { paths: ['/firstName', '/lastName'] }
    ]
  };

  try {
    // 创建或更新容器时应用唯一键策略
    await container.replace({
      id: containerName,
      uniqueKeyPolicy: uniqueKeyPolicy
    });
    console.log('Unique key policy created successfully.');
  } catch (error) {
    console.error('Error creating unique key policy:', error);
  }
}

createUniqueKey().catch(console.error);
