如何在没有此错误的情况下将 unix 日期传递给时刻 js："Deprecation warning: value provided is not in a recognized RFC2822 or

Question

我通读了所有其他类似的问题，但仍然找不到解决问题的方法。

我在节点中有一个应用程序.js它使用时刻.js。

(1st( 应用程序通过对 API 的 HTTP 请求getUNIX 日期，然后 (2nd( 将其传递给 moment.js

如下所示

const contractEndDate = 1619740800000;
const readablecontractEndDate = moment(`${contractEndDate}`, "x").format("dddd, MMMM Do YYYY, h:mm:ss a");
const preparationPeriod = 90;
const taskDate = moment.utc(contractEndDate).subtract(preparationPeriod, 'days').valueOf();
const readableTaskDate = moment(taskDate).format("dddd, MMMM Do YYYY, h:mm:ss a");
console.log(`contract end date is ${readablecontractEndDate} and task date is ${taskDate} or ${readableTaskDate}`)
/*Output: Deprecation warning: value provided is not in a recognized RFC2822 or ISO format. moment construction falls back to js Date(), which is not reliable across all browsers and versions. Non RFC2822/ISO date formats are discouraged and will be removed in an upcoming major release. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.

它在此代码笔中工作正常：

但是我不明白为什么当我运行我的应用程序时它不起作用。

Answer 1

我真的不明白为什么，但是在相同的代码工作没有任何错误的第二天

const contractEndDate = 1619740800000;
const readablecontractEndDate = moment(`${contractEndDate}`, "x").format("dddd, MMMM Do YYYY, h:mm:ss a");
const preparationPeriod = 90;
const taskDate = moment.utc(contractEndDate).subtract(preparationPeriod, 'days').valueOf();
const readableTaskDate = moment(taskDate).format("dddd, MMMM Do YYYY, h:mm:ss a");
console.log(`contract end date is ${readablecontractEndDate} and task date is ${taskDate} or ${readableTaskDate}`)
