为集合中的每个文档生成新的Mongo对象id？

const { MongoClient, ObjectId } = require('mongodb');

async function main() {
  const uri = 'your_mongodb_connection_string';
  const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });

  try {
    await client.connect();
    const database = client.db('your_database_name');
    const collection = database.collection('your_collection_name');

    // 假设我们有一个文档数组
    const documents = [
      { name: 'Alice', age: 25 },
      { name: 'Bob', age: 30 }
    ];

    // 为每个文档生成新的 ObjectId
    const documentsWithIds = documents.map(doc => ({
      _id: new ObjectId(),
      ...doc
    }));

    // 插入文档到集合中
    const result = await collection.insertMany(documentsWithIds);
    console.log('Inserted documents:', result.insertedIds);
  } finally {
    await client.close();
  }
}

main().catch(console.error);
