如何在Angular中为开发版和生产版应用程序设置不同的i18n资源路径

"assets": [
  {
    "glob": "**/*",
    "input": "src/assets",
    "output": "/assets"
  },
  {
    "glob": "**/*.json",
    "input": "src/i18n-dev",
    "output": "/i18n"
  }
]

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})
export class I18nService {
  private i18nPath: string;

  constructor(private http: HttpClient) {
    this.i18nPath = '/i18n'; // 默认为开发版的i18n资源路径
  }

  setProductionMode() {
    this.i18nPath = '/assets/i18n-prod'; // 切换为生产版的i18n资源路径
  }

  getTranslation(lang: string) {
    const url = `${this.i18nPath}/${lang}.json`;
    return this.http.get(url);
  }
}

import { Component, OnInit } from '@angular/core';
import { I18nService } from './i18n.service';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent implements OnInit {
  translation: any;

  constructor(private i18nService: I18nService) { }

  ngOnInit() {
    this.i18nService.getTranslation('en').subscribe((data: any) => {
      this.translation = data;
    });
  }
}
