【问题描述】：

我有以下 IP 和端口，但我想将其与环境变量一起携带，以便可以从那里进行编辑

import  ClientsModuleOptions, Transport  from "@nestjs/microservices"

export const GatewayOptions: ClientsModuleOptions = [
    
        name: 'MICRO-ADMIN',
        transport: Transport.TCP,
        options: 
            host: '127.20.20.2',
            port: 4000,
        ,
    ,
    
        name: 'MICRO-DEV',
        transport: Transport.TCP,
        options: 
            host: '127.30.30.3',
            port: 5000,
        ,
    ,
];

我将此配置导入模块。

import  Module  from '@nestjs/common';
import  ClientsModule  from '@nestjs/microservices';
import  GatewayOptions  from 'src/utils/gateway/gateway';
import  AuthModule  from './../auth/auth.module';
import  CategoryModule  from './../category/category.module';
import  GameController  from './game.controller';
import  GameService  from './game.service';

@Module(
  imports: [
    AuthModule,
    CategoryModule,
    ClientsModule.register(GatewayOptions)
   ],
  controllers: [GameController],
  providers: [GameService],
  exports: [GameService],
)
export class GameModule 

【参考方案1】：

你需要使用 register async 才能使用ConfigService

关注文档：https://docs.nestjs.com/microservices/basics#client

@Module(
  providers: [
    
      provide: 'MATH_SERVICE',
      useFactory: (configService: ConfigService) => 
        const mathSvcOptions = configService.getMathSvcOptions();
        return ClientProxyFactory.create(mathSvcOptions);
      ,
      inject: [ConfigService],
    
  ]
  ...
)

以下是配置ConfigService的方法：https://docs.nestjs.com/techniques/configuration#configuration
