1、下载

npm install --save @nestjs-modules/ioredis ioredis

2、全局模块中引用

RedisModule.forRootAsync({useFactory: (configService: ConfigService) => {return {type:"single",url: configService.get('redis.url')  };},inject: [ConfigService],
}),

整体如下：

import { Global, Module } from '@nestjs/common';
import { ConfigModule, ConfigService } from '@nestjs/config';
import { TypeOrmModule, TypeOrmModuleOptions } from '@nestjs/typeorm';
import configuration from '../../config/index';
import { JwtModule } from '@nestjs/jwt';
import { APP_FILTER, APP_GUARD, APP_INTERCEPTOR } from '@nestjs/core';
import { JwtGuard } from 'src/utils/jwt/jwt-guard';
import { JwtStrategy } from 'src/utils/jwt/jwt-strategy';
import { WinstonService } from 'src/utils/logger/winston-service';
import { CatchLoggerFilter } from 'src/utils/logger/catch-logger-filter';
import { ResponseLoggerInterceptor } from 'src/utils/logger/response-logger-interceptor';
import { RedisModule } from '@nestjs-modules/ioredis';
import { RequirePermissionGuard } from 'src/utils/premission/require-premission.guard';@Global()
@Module({imports: [ConfigModule.forRoot({isGlobal: true,load: [configuration],}),TypeOrmModule.forRootAsync({inject: [ConfigService],useFactory: (configService: ConfigService) => {return {type: 'mysql',...configService.get('db.mysql'),timezone: '+08:00',// logger: 'advanced-console',entities: [__dirname + '/../**/*.entity.{js,ts}'],} as TypeOrmModuleOptions;},}),RedisModule.forRootAsync({inject: [ConfigService],useFactory: (configService: ConfigService) => {return {type:"single",url: configService.get('redis.url'),};},}),JwtModule.registerAsync({inject: [ConfigService],global: true,useFactory: (configService: ConfigService) => {return {secret: configService.get('jwt.secretkey'),// signOptions: { expiresIn: configService.get('jwt.expiresin') },};},})],providers: [JwtStrategy,{provide: APP_GUARD,useFactory: (configService: ConfigService) => {return new JwtGuard(configService);},inject: [ConfigService],},{provide: APP_GUARD,useClass: RequirePermissionGuard},{provide: WinstonService,inject: [ConfigService],useFactory: (configService: ConfigService) => {return new WinstonService(configService);}},{provide: APP_FILTER,useClass: CatchLoggerFilter},{provide: APP_INTERCEPTOR,useClass: ResponseLoggerInterceptor}],exports: [WinstonService],
})
export class ShareModule { }

3、使用

// 引入
import { InjectRedis } from '@nestjs-modules/ioredis';
import Redis from 'ioredis';

// 注入
constructor(@InjectRedis() private readonly redis: Redis
) { }

// 使用
this.redis.set(CacheEnum.LOGIN_TOKEN_KEY + data.userId, access_token, 'EX', 60 * 60 * 2);this.redis.del(CacheEnum.LOGIN_TOKEN_KEY + userId);this.redis.get(base_enum_1.CacheEnum.LOGIN_TOKEN_KEY + payload.userId)
