如何使用NodeJS将UTC日期格式化为“YYYY-MM-DD hh:mm:ss”字符串?

问题描述:

使用NodeJS,我想将 Date 格式化为以下字符串格式:

Using NodeJS, I want to format a Date into the following string format:

var ts_hms = new Date(UTC);
ts_hms.format("%Y-%m-%d %H:%M:%S");

我该怎么做?

如果您正在使用Node.js,那么您肯定要使用EcmaScript 5,因此Date具有 toISOString 方法。您要求稍微修改ISO8601:

If you're using Node.js, you're sure to have EcmaScript 5, and so Date has a toISOString method. You're asking for a slight modification of ISO8601:

new Date().toISOString()
> '2012-11-04T14:51:06.157Z'

所以只需剪掉一些东西,你设置好了:

So just cut a few things out, and you're set:

new Date().toISOString().
  replace(/T/, ' ').      // replace T with a space
  replace(/\..+/, '')     // delete the dot and everything after
> '2012-11-04 14:55:45'

或者,在一行中: new Date()。toISOString()。replace(/ T /,'')。renplace(/ \ .. + /,'')

ISO8601必然是UTC(也由第一个结果的尾随Z表示),所以你默认得到UTC(总是好事)。

ISO8601 is necessarily UTC (also indicated by the trailing Z on the first result), so you get UTC by default (always a good thing).
