NestJS应用程序如何侦听与连接的微服务相同的端口？

npm install --save @nestjs/microservices

import { Module } from '@nestjs/common';
import { MicroserviceModule } from '@nestjs/microservices';

@Module({
  imports: [MicroserviceModule],
})
export class AppModule {}

import { Module } from '@nestjs/common';
import { MicroserviceModule } from '@nestjs/microservices';

@Module({
  imports: [MicroserviceModule.register({
    transport: Transport.TCP,
    options: {
      port: 3001, // 与连接的微服务相同的端口
    },
  })],
})
export class AppModule {}

import { Controller } from '@nestjs/common';
import { Client, ClientProxy, Transport } from '@nestjs/microservices';

@Controller()
export class AppController {
  @Client({ transport: Transport.TCP })
  client: ClientProxy;
}
