NodeJS：属性从响应中消失？

Question

在我的控制台中：

[ CampaignStrategy {
    id: 248,
    id_mm: 828419,
    strategy_name: "Norhart_Encore_AUD",
    impressions: 7623,
    clicks: 13,
    TEST_PROPERTY: '222222',
    ordered_impressions:
     Orderedimpression { ordered_impressions: '123', id: 7, strategy_id: 248 }
    },
  ...
]

浏览器中收到的响应对象 (XHR)：

[
  {
    "id": 248,
    "id_mm": 828419,
    "strategy_name": "Norhart_Encore_AUD",
    "impressions": 7623,
    "clicks": 13,
},
...
]

请注意 TEST_PROPERTY 和 ordered_impressions 如何不存在于后者中。我究竟做错了什么？这是我的控制器逻辑：

@get('/campaignStrategies/{id}')
  async findStrategies(
    @param.path.number('id') id: number,
  ): Promise<any> {
    const campaignStrats = await this.campaignStrategyRepository.find({
      where: {
        campaignId: id
      }
    });

    const campaignStratsIds = campaignStrats.map(strat => {
      return { strategy_id: strat.id }
    });

    const campaignSettings = await this.orderedimpressionRepository.find({
      where: {
        or: campaignStratsIds
      }
    });

    const settingsTable = await campaignSettings.reduce((acc: any, setting: any) => {
      acc[setting.strategy_id] = setting;
      return acc;
    }, {});

    const fullData = campaignStrats.map((strat: any) => {
      strat['TEST_PROPERTY'] = '222222'
      strat['ordered_impressions'] = settingsTable[`${strat.id}`];
      return strat;
    });

    console.log(fullData);

    return fullData;
  }

Answer 1

你应该试试：

const fullData = campaignStrats
    .map((strat: any) => { 
        return {...strat, TEST_PROPERTY: 2222 /* and so on /* } 
    }

通过这种方式，您 return 一个与 campaignStrats 列表中的对象不同的对象。

PS：我不确定，为什么 console.log 向我们展示了错误的反应想法，也许有人会在这里发表评论或编辑。
