如何在带有feathersjs的服务类中使用查询mongoose

npm install @feathersjs/feathers mongoose

const mongoose = require('mongoose');
const { Schema } = mongoose;

const myModelSchema = new Schema({
  // 定义模型的字段
  // ...
});

const myModel = mongoose.model('myModel', myModelSchema);

module.exports = function (app) {
  // ...
};

module.exports = function (app) {
  class MyService {
    async find(params) {
      try {
        // 使用Mongoose进行查询
        const result = await myModel.find().exec();

        return result;
      } catch (error) {
        throw new Error('查询失败');
      }
    }

    // 其他服务方法...
  }

  app.use('/my-service', new MyService());
};

const feathers = require('@feathersjs/feathers');
const mongoose = require('mongoose');

mongoose.connect('mongodb://localhost:27017/my-database', {
  useNewUrlParser: true,
  useUnifiedTopology: true,
})
  .then(() => console.log('已连接到数据库'))
  .catch(err => console.error('数据库连接失败', err));

const app = feathers();

// 注册服务类和其他配置...

app.listen(3000);
