如何在Angular8.0下使用ngx-translate进行国际化配置

一. 将ngx-translate添加到angular应用程序中

npm install @ngx-translate/core @ngx-translate/http-loader rxjs --save

二.在app.module.ts中初始化翻译translatemodule

import { browsermodule } from '@angular/platform-browser';
import { ngmodule } from '@angular/core';

import { appcomponent } from './app.component';

// import ngx-translate and the http loader
import {translateloader, translatemodule} from '@ngx-translate/core';
import {translatehttploader} from '@ngx-translate/http-loader';
import {httpclient, httpclientmodule} from '@angular/common/http';

@ngmodule({
  declarations: [
    appcomponent
  ],
  imports: [
    browsermodule,

    // ngx-translate and the loader module
    httpclientmodule,
    translatemodule.forroot({
      loader: {
        provide: translateloader,
        usefactory: httploaderfactory,
        deps: [httpclient]
      }
    })
  ],
  providers: [],
  bootstrap: [appcomponent]
})
export class appmodule { }

// required for aot compilation
export function httploaderfactory(http: httpclient) {
  return new translatehttploader(http);
}

三.在app.component.ts中设置初始值

import {component} from '@angular/core';
import {translateservice} from '@ngx-translate/core';

@component({
  selector: 'app-root',
  templateurl: './app.component.html',
  styleurls: ['./app.component.scss']
})
export class appcomponent {
  constructor(private translate: translateservice) {
    translate.setdefaultlang('en');
  }
}

四.在assets/i18n文件下创建让我们为英文翻译创建相关语言json文件，如en.json文件

{
 "demo.title": "translation demo",
 "demo.text": "this is a simple demonstration app for ngx-translate"
}

五.在app.component.html中使用

<div>
  <!-- translation: translation pipe -->
  <h1>{{ 'demo.title' | translate }}</h1>

  <!-- translation: directive (key as attribute)-->
  <p [translate]="'demo.text'"></p>

  <!-- translation: directive (key as content of element) -->
  <p translate>demo.text</p>
</div>
