NestJS 网关依赖注入

Question

我有一个名为“PlayerService”的服务，网关称为“Player Gateway”，PlayersGateway 依赖于 PlayerService，但我无法在网关内注入服务。

玩家网关

@UseInterceptors(RedisPropagatorInterceptor)
@WebSocketGateway()
@Injectable()
export class PlayerGateway
  extends BaseGateway
  implements OnGatewayConnection, OnGatewayInit, OnGatewayDisconnect {

constructor(private playerService: PlayerService) {
    super();
  }

播放器服务

@Injectable()
export class PlayerService extends BaseService<Player> {
  protected fieldsSearchable: FieldsSearchable = {};

  private logger = new Logger('PlayerService');

  constructor(
    @InjectRepository(PlayerRepository)
    repository: PlayerRepository,
    @Inject(REQUEST) protected request: Request,
    private redisService: RedisService,
  ) {
    super();
    this.setRepository(repository);
  }

播放器模块

@Module({
  imports: [
    TypeOrmModule.forFeature([Player, PlayerRepository]),
    RedisModule,
    SocketModule,
    RedisPropagatorModule,
  ],
  controllers: [PlayerController],
  exports: [TypeOrmModule, PlayerService],
  providers: [PlayerService, PlayerGateway],
})
export class PlayerModule {}

Modules.ts

@Module({
  imports: [
    RedisModule,
    SocketModule,
    RedisPropagatorModule,
    SessionModule,
    PlayerModule,
  ],
  exports: [RedisModule, SocketModule],
  controllers: [],
  providers: [ServerGateway, NetworkGateway],
})

我想知道的是如何将服务注入网关或制作类似这样的 rsrs

您的 PlayerService 正在尝试注入请求：

@Inject(REQUEST) protected request: Request

这对于构建网关实例没有意义，因为它应该独立于任何单独的 HTTP 请求。您真的需要访问 PlayerService 中的请求吗？如果是这样，您必须将其拆分为单独的服务
