如何查询服务器以检索ember.js中的单个记录/数据？

ember generate model post

import Model, { attr, belongsTo, hasMany } from '@ember-data/model';

export default class PostModel extends Model {
  @attr('string') title;
  @attr('string') content;
  @belongsTo('author') author;
  @hasMany('comment') comments;
}

ember generate adapter post

import JSONAPIAdapter from '@ember-data/adapter/json-api';

export default class PostAdapter extends JSONAPIAdapter {
  // 重写适配器的findRecord方法
  async findRecord(store, type, id, snapshot) {
    const url = `https://example.com/posts/${id}`;
    const response = await fetch(url);
    const data = await response.json();
    return data;
  }
}

import Controller from '@ember/controller';
import { inject as service } from '@ember/service';

export default class MyController extends Controller {
  @service store;

  async fetchPost() {
    const post = await this.store.findRecord('post', 1);
    console.log(post);
  }
}
