如何在NestJS中使用文本类型作为服务构造函数参数

$ npm i -g @nestjs/cli
$ nest new project-name

$ nest generate service text-service

import { Injectable } from '@nestjs/common';

@Injectable()
export class TextService {
  constructor(private readonly message: string) {}

  // 添加其他方法和逻辑
}

import { Module } from '@nestjs/common';
import { TextService } from './text.service';

@Module({
  providers: [TextService],
})
export class AppModule {
  constructor(private readonly textService: TextService) {}
}

import { Injectable } from '@nestjs/common';

@Injectable()
export class TextService {
  constructor(private readonly message: string) {}

  printMessage() {
    console.log(this.message);
  }
}

import { Controller, Get } from '@nestjs/common';
import { TextService } from './text.service';

@Controller()
export class AppController {
  constructor(private readonly textService: TextService) {}

  @Get()
  getHello(): string {
    this.textService.printMessage();
    return 'Hello World!';
  }
}
