NestJS로 텔레그램 봇용 팩트 생성기 만들기

Google로 이동하여 무료 농담 생성기가 있는 사이트를 찾아야 합니다. 사이트는 SPA가 아니어야 합니다.

나는 두 번째를 선택했다.

libs/facts-generator/server/src/lib/facts-generator-services/facts-generator.service.ts 파일 생성

import { ScraperService } from '@kaufman-bot/html-scraper/server';
import { Injectable } from '@nestjs/common';

@Injectable()
export class FactsGeneratorService {
  constructor(private readonly scraperService: ScraperService) {}

  async onMessage(msg) {
    let result = await this.scraperService.onMessage(msg);
    if (result !== null) {
      result = result.replace('\n\nTweet [http://twitter.com/share]', '');
    }
    return result;
  }
}

libs/facts-generator/server/src/lib/facts-generator.module.ts 파일 생성

import { ScraperModule } from '@kaufman-bot/html-scraper/server';
import { DynamicModule, Module } from '@nestjs/common';
import { getText } from 'class-validator-multi-lang';
import { FactsGeneratorService } from './facts-generator-services/facts-generator.service';

@Module({})
export class FactsGeneratorModule {
  static forRoot(): DynamicModule {
    return {
      module: FactsGeneratorModule,
      imports: [
        ScraperModule.forRoot({
          contentSelector: '#z',
          help: getText('Random facts generator'),
          spyWords: [getText('facts')],
          removeWords: [getText('get'), getText('please')],
          uri: 'http://randomfactgenerator.net/',
        }),
      ],
      providers: [FactsGeneratorService],
      exports: [ScraperModule, FactsGeneratorService],
    };
  }
