Firebase Cloud功能中的本地化错误 [英] Wrong localisation in Firebase Cloud Function

问题描述

在firebase云功能中执行时，以下命令将返回美国格式，而不是本地化格式. 但是，它在浏览器中效果很好.

When executed in firebase cloud functions, the following command returns the American format instead of the localised one. However, it works well in browsers.

price.toLocaleString("pt-BR", {
  maximumFractionDigits: 2
});

toLocaleString()在Firebase云函数中是否可以正常工作?

Is there any way toLocaleString() works properly in firebase cloud functions ?

更新:

let price = 1456.21
let formattedPrice = price.toLocaleString("pt-BR", {maximumFractionDigits: 2});

//Value of formattedPrice expected: 1.456,21 (it works in browsers).
//Value of formattedPrice returned in Firebase Cloud Functions: 1,456.21

也许与Node的默认ICU(--with-intl = small-icu)有关.为了支持国际化，似乎该值应为--with-intl = full-icu.

Maybe it something related to the default ICU of Node (--with-intl=small-icu) . To support internationalization, it seems the value should be --with-intl=full-icu .

推荐答案

您不应依赖特殊标志来构建Cloud Functions中使用的节点版本.相反，您可以做的是引入处理格式化语言环境字符串的模块.例如，您可以使用 intl 模块:

You shouldn't depend on special flags for building the version of node used in Cloud Functions. What you can do instead is pull in a module that deals with formatting locale strings. For example, you can use the intl module:

npm install intl

使用此:

const intl = require('intl')
const format = intl.NumberFormat("pt-BR", {maximumFractionDigits: 2})
console.log(format.format(price))
