如何从NestJS CacheManager模块获取redis io客户端

npm install cache-manager redis

import { Module } from '@nestjs/common';
import { CacheModule } from '@nestjs/common';
import { RedisCacheModule } from '@nestjs/common';

@Module({
  imports: [
    CacheModule.register(),
    RedisCacheModule.register({
      host: 'localhost', // Redis服务器主机名
      port: 6379, // Redis服务器端口号
    }),
  ],
})
export class AppModule {}

import { Injectable, Inject } from '@nestjs/common';
import { CacheManager } from '@nestjs/common';

@Injectable()
export class MyService {
  constructor(
    @Inject(CacheManager) private readonly cacheManager: CacheManager,
  ) {}

  async getRedisClient() {
    const redisClient = this.cacheManager.store.getClient();
    return redisClient;
  }
}
