如何在nodejs中将mongo字符串解析为object？

npm install mongodb

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

const uri = 'mongodb://localhost:27017'; // MongoDB连接URI
const dbName = 'mydatabase'; // 数据库名称
const collectionName = 'mycollection'; // 集合名称

async function parseMongoString(mongoString) {
  const client = new MongoClient(uri);
  await client.connect();

  const db = client.db(dbName);
  const collection = db.collection(collectionName);

  // 解析Mongo字符串为对象
  const parsedObject = await collection.findOne({ _id: mongoString });

  await client.close();

  return parsedObject;
}

const mongoString = '5f7a7e4b9d3b0a001f6b5e4c';
parseMongoString(mongoString)
  .then(parsedObject => {
    console.log(parsedObject);
  })
  .catch(error => {
    console.error(error);
  });
