如何获取集合中所有文档的ID并将其存储在字符串数组中？

const MongoClient = require('mongodb').MongoClient;
const uri = 'mongodb+srv://<username>:<password>@<cluster-url>/<database>?retryWrites=true&w=majority';

async function getAllDocumentIds() {
  const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });
  try {
    await client.connect();
    const collection = client.db('<database>').collection('<collection>');
    const documents = await collection.find({}).toArray();
    const documentIds = documents.map(doc => doc._id.toString());
    return documentIds;
  } finally {
    await client.close();
  }
}

getAllDocumentIds()
  .then(ids => console.log(ids))
  .catch(err => console.error(err));
