nestjs 连接redis

1、下载

TypeScript 复制代码

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

2、全局模块中引用

TypeScript 复制代码

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

整体如下：

TypeScript 复制代码

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

TypeScript 复制代码

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

TypeScript 复制代码

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

TypeScript 复制代码

// 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)
