遍历对象数组以过滤特定数据

Question

我正在尝试通过API调用过滤特定的数据。对象不是可迭代的，我尝试了百万种不同的方式来获取所需的特定数据。

所以...我需要过滤掉tip_money并仅返回该数据而不是完整响应。

这里是电话

router.get('/', auth, (req, res) => {
    try {
        apiInstance.listPayments(opts).then(function (payments) {
            res.send(payments)
        })
    } catch (error) {
        console.error(error)
    }
});

这是响应（部分）：

看看类似的东西是否对您有用

router.get('/tips', auth, (req, res) => {
    try {
        apiInstance.listPayments(opts).then(function (payments) {
            const tips = payments.map(payment => payment.tip_money).filter(tip => tip != undefined);
            res.send(tips);
        })
    } catch (error) {
        console.error(error)
    }
});

如果您还希望端点返回未定义的提示，请在最后删除.filter，因为似乎所有的付款都没有提示。
