如何使用i18n在angular中翻译自定义管道？

{
  "customPipe": {
    "hello": "Hello",
    "world": "World"
  }
}

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule, HttpClient } from '@angular/common/http';
import { TranslateModule, TranslateLoader } from '@ngx-translate/core';
import { TranslateHttpLoader } from '@ngx-translate/http-loader';

export function HttpLoaderFactory(http: HttpClient) {
  return new TranslateHttpLoader(http, './assets/translations/', '.json');
}

@NgModule({
  imports: [
    BrowserModule,
    HttpClientModule,
    TranslateModule.forRoot({
      loader: {
        provide: TranslateLoader,
        useFactory: HttpLoaderFactory,
        deps: [HttpClient]
      }
    })
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

import { Pipe, PipeTransform } from '@angular/core';
import { TranslateService } from '@ngx-translate/core';

@Pipe({
  name: 'customPipe'
})
export class CustomPipe implements PipeTransform {
  constructor(private translate: TranslateService) { }

  transform(value: any): any {
    // 使用translate.instant方法来获取翻译文本
    const translatedValue = this.translate.instant(`customPipe.${value}`);
    return translatedValue || value;
  }
}

<p>{{ 'hello' | customPipe }}</p>
<p>{{ 'world' | customPipe }}</p>
