如何更新mongoose中的特定字段

const mongoose = require('mongoose');

const Schema = mongoose.Schema;

const yourSchema = new Schema({
  field1: String,
  field2: Number,
  field3: Boolean
});

const YourModel = mongoose.model('YourModel', yourSchema);

YourModel.findOneAndUpdate(
  { _id: 'yourDocumentId' }, // 查询条件，可以根据需要修改
  { $set: { field1: 'newValue' } }, // 更新的字段和值
  { new: true } // 选项，返回更新后的文档
)
  .then(updatedDocument => {
    console.log(updatedDocument);
  })
  .catch(error => {
    console.log(error);
  });
