1. 安装依赖

npm i @tirke/node-cache-manager-ioredis cache-manager

2. 创建redis 模块和服务

1. 生成并编辑module

生成module

nest g mo redis

编辑模块

// redis.module.ts
import { Module } from '@nestjs/common';
// import { redisClient } from './redis.client';
import { ioRedisStore, RedisCache } from '@tirke/node-cache-manager-ioredis';
import { caching } from 'cache-manager';
@Module({providers: [{provide: 'REDIS_CLIENT',useValue: async () => {const redisCache: RedisCache = await caching(ioRedisStore, {host: '192.168.50.3', // default valueport: 6379, // default valuepassword: '',ttl: 600,});// listen for redis connection error eventconst cache = redisCache.store;cache.client.on('error', (error: unknown) => {console.error('Redis error:', error);});},},],exports: ['REDIS_CLIENT'],
})
export class RedisModule {}

2.生成并编辑redis service

生成service

nest g s redis

编辑service

// redis.service.ts
import { Injectable } from '@nestjs/common';
import { Inject } from '@nestjs/common';
import { Redis } from 'ioredis';@Injectable()
export class RedisService {constructor(@Inject('REDIS_CLIENT') private readonly client: Redis) {}async set(key: string, value: any): Promise<void> {await this.client.set(key, value);}async get(key: string): Promise<string | null> {return this.client.get(key);}async del(key: string): Promise<number> {return this.client.del(key);}
}

note: 记得删除app.mudule.ts 中的引用

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { MongooseModule } from '@nestjs/mongoose';import { ConfigModule } from '@nestjs/config';
// import { RedisModule } from './redis/redis.module';刪除@Module({imports: [ConfigModule.forRoot({isGlobal: true,envFilePath: ['.env.development.local', '.env.development', '.env'],//If a variable is found in multiple files, the first one takes precedence.}),MongooseModule.forRoot(process.env.MONGO_URI),UserModule,AuthModule,MemberModule,//  RedisModule,刪除],controllers: [AppController],providers: [AppService,RedisService],
})
export class AppModule {}

3. 调用服务

1.使用的模块导入RedisService和模块RedisModule

...
import { RedisService } from 'src/redis/redis.service';
import { RedisModule } from 'src/redis/redis.module';@Module({imports: [RedisModule,....],providers: [...RedisService],exports: [AuthService],controllers: [AuthController],
})
export class AuthModule {}

2. 调用

import { Injectable } from '@nestjs/common';
import { RedisService } from 'src/redis/redis.service';
@Injectable()
export class AuthService {constructor(private readonly redisService: RedisService,) {}async login(member: MemberLoginDto) {...await this.redisService.set(`token:${accessToken}`, memberInfo);}
}
