NestJS + express-session + redis-connect 实现问题

Question

我正在尝试在我的 NestJS 后端中实现

express-session

包以及

connect-redis

来进行会话存储，但是我收到了如下错误。我什至将商店内的客户端更改为

RedisClient

，这是在提供程序文件中声明的注入令牌，但仍然没有运气，我到底错在哪里？实现此类功能的最佳实践是什么，以便我可以使用 redis 作为会话存储，无论是使用

connect-redis

还是其他东西......提前非常感谢，任何帮助表示赞赏

redis.provider.ts

import { FactoryProvider } from '@nestjs/common';
import { Redis } from 'ioredis';
import { ConfigService } from '@nestjs/config';

export const redisClientFactory: FactoryProvider<Redis> = {
  provide: 'RedisClient',
  inject: [ConfigService],
  useFactory: (configService: ConfigService) => {
    const redisInstance = new Redis({
      host: configService.get('REDIS_HOST'),
      port: configService.get('REDIS_PORT'),
      password: configService.get('REDIS_PASSWORD'),
    });

    redisInstance.on('error', (error) => {
      console.error('Redis error', error);
    });

    return redisInstance;
  },
};

甚至将商店内的客户端更改为RedisClient，这是在提供程序文件中声明的注入令牌

不熟悉这个库，但这对我来说看起来像是一个普通的 TypeScript 错误。

RedisStore

类是一个类，需要

new

运算符来实例化它。然而，它就像括号内的函数一样被调用。

new (RedisStore(session))

我会尝试移动

new

并查看错误是否发生变化：

(new RedisStore(session))

希望这有帮助。
