如何在NestJS中使用fastify设置自定义内容类型？

npm install --save @nestjs/core @nestjs/common fastify

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import * as fastify from 'fastify';

async function bootstrap() {
  const app = await NestFactory.create(AppModule, new fastify.FastifyAdapter());
  // 其他配置和中间件
  await app.listen(3000);
}
bootstrap();

import { Controller, Get, Res } from '@nestjs/common';
import { Response } from 'fastify';

@Controller('example')
export class ExampleController {
  @Get()
  async getExample(@Res() res: Response) {
    res.header('Content-Type', 'application/custom-type');
    return 'Custom content type';
  }
}
