获取 Ionic 应用程序的当前语言

Question

I am developing an Ionic 3 App based on WooCommerce database using rest API.

I use Polylang Plugin to translate my WorrdPress website, and because this plugin does not support rest API, I decided to use "include" parameter when I query categories, in order to get them in one language.

Ex:

this.http.get(this.config.setUrl('GET', '/wp-json/wc/v2/products/categories?', {
  per_page: 120, include: '151,152,929'
})

Is there a way to check the current language of the app, and based on that to query certain categories?

Something like:

if ( currentLang = 'en' ){
this.http.get(this.config.setUrl('GET', '/wp-json/wc/v2/products/categories?', {
per_page: 120, include: '151,152,929'
}else ... 

Thank you in advance!

Answer 1

You have to use Ionic native Globalization plugin for get current language,

import { Globalization } from '@ionic-native/globalization';

this.globalization.getPreferredLanguage()
  .then(res => console.log(res))
  .catch(e => console.log(e));

Thank you.

You can do that using ngx-translate

import { TranslateService } from '@ngx-translate/core';

constructor(private translate: TranslateService) {
  console.log(this.translate.getBrowserLang());
}

Hint:
Ionic native Globalization plugin is deprecated
