使用nestjs框架和cash manager来连接redis缓存。我可以连接redis，但是当我使用set/get等方法时，会显示set不是函数的错误。添加了app module、service和package json以供参考

应用程序模块.ts

import { Module, CacheModule } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
const config = require('./config');
import { Logger } from './logger';
import * as redisStore from 'cache-manager-redis-store';
import type { RedisClientOptions } from "redis"

@Module({
  imports: [
    CacheModule.register({
      // @ts-ignore
      store: async () => await redisStore({
        // Store-specific configuration:
        socket: {
          host: '******',
          port: 6380,
          password: '*****'
        }
      })
    }),
    HttpModule
  ],
  controllers: [AppController],
  providers: [AppService, Logger],
  exports: [Logger],
})
export class AppModule {}

应用程序.服务.ts

import { Cache } from 'cache-manager';
import {
  HttpException,
  HttpStatus,
  Injectable,
  OnApplicationBootstrap,
  OnApplicationShutdown,
  CACHE_MANAGER,
  Inject
} from '@nestjs/common';

@Injectable()
export class DeviceOnboardService
  implements OnApplicationBootstrap, OnApplicationShutdown
{

  constructor(
    @Inject(CACHE_MANAGER) private cacheManager: Cache,
    private logger: Logger
  ) {}
  
  async getData(){
    await this.cacheManager.set('test', 'XYZ', 600);
  }

}

异步配置需要使用useFactory进行配置，它允许您使用async await，如果需要动态配置，还可以注入服务
当您使用useFactory时，您可以接着使用imports数组和inject。如下列范例所示，如果需要，您可以在'imports'数组中汇入configModule，并在inject数组中汇入configService。

CacheModule.registerAsync<RedisClientOptions>({
  imports: [ConfigModule],
  useFactory: async (configService: ConfigService) => {
    const store = await redisStore({
      socket: {
        host: configService.get('REDIS_HOST'),
        port: configService.get('REDIS_PORT'),
      },
    });

    return {
      store: {
        create: () => store,
      },
    };
  },
  inject: [ConfigService],
})

你需要返回store引用到create方法，如下面的链接所示，这里有两种类型的store，那么它应该可以工作
