通过单击按钮通过Mongoose和Express删除文档

// 导入所需模块
const express = require('express');
const mongoose = require('mongoose');

// 建立与数据库的连接
mongoose.connect('mongodb://localhost/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => console.log('Connected to MongoDB'))
  .catch(err => console.error('Failed to connect to MongoDB', err));

// 定义文档模型
const Document = mongoose.model('Document', yourSchema);

// 创建Express应用
const app = express();

// 处理删除文档的请求
app.delete('/documents/:id', (req, res) => {
  const documentId = req.params.id;

  // 使用Mongoose删除文档
  Document.findOneAndDelete({ _id: documentId }, (err, result) => {
    if (err) {
      console.error('Failed to delete document', err);
      res.status(500).send('Failed to delete document');
    } else {
      console.log('Document deleted successfully');
      res.status(200).send('Document deleted successfully');
    }
  });
});

// 启动服务器
app.listen(3000, () => console.log('Server started on port 3000'));
