如何获得额外的客户端连接(nestjs-ioredis)

npm install --save nestjs-ioredis ioredis

import { Module } from '@nestjs/common';
import { IoredisModule } from 'nestjs-ioredis';

@Module({
  imports: [
    IoredisModule.forRoot({
      name: 'redisConnection', // 连接名
      host: 'localhost', // Redis服务器主机名
      port: 6379, // Redis服务器端口号
    }),
  ],
})
export class AppModule {}

import { Controller, Get } from '@nestjs/common';
import { InjectRedis } from 'nestjs-ioredis';
import { Redis } from 'ioredis';

@Controller('example')
export class ExampleController {
  constructor(@InjectRedis('redisConnection') private readonly redis: Redis) {}

  @Get()
  async getData(): Promise<string> {
    const data = await this.redis.get('key');
    return data;
  }
}
