Redis 笔记1
Redis缓存基础
redis引用如下:
Nuget CSRedisCore
需要redis代替系统cache,需要引用:
Nuget Microsoft.Extensions.Caching.Redis
1、首先建的全局静态类
public class RedisConfig { public static CSRedisClient Database0 { get; set; } }
2、在startup.cs配置
使用Redis代替系统缓存
//使用Redis代替系统缓存 services.AddDistributedRedisCache(option => { option.Configuration = string.Format("{0}:{1},allowAdmin=true,password={2},defaultdatabase={3}", "IP地址", "端号", "密码", 15);//最后一个表 option.InstanceName = "RedisCache:GatewayOcelotAPI:Name"; });
使用第三方Redis工具
//使用第三方Redis工具 string config0 = string.Format("{0}:{1},allowAdmin=true,password={2},defaultdatabase={3}", "IP地址", "端口号", "密码", 0); //实例化一个单例 RedisConfig.Database0 = new CSRedis.CSRedisClient(config0);
3、使用
private IDistributedCache _cache; public ValuesController(IDistributedCache cache) { _cache = cache; } //使用第三方redis工具直接访问Redis服务 [HttpGet("Redis")] public string GetValueByRedis() { //初始化 RedisHelper.Initialization(RedisConfig.Database0); string RedisName = "MyName"; //最简单的使用 if (RedisHelper.Exists(RedisName)) { return RedisHelper.Get(RedisName); } else { var RedisValues = "this is Value by Redis"; if (!string.IsNullOrEmpty(RedisValues)) { RedisHelper.Set(RedisName, RedisValues, 3600); } return RedisValues; } } //使用系统自带cache [HttpGet("Cache")] public string GetValueByCache() { var CacheName = "MyCacheName"; var CacheValue = "This is Value by Cache"; //配置选项 DistributedCacheEntryOptions options = new DistributedCacheEntryOptions(); options.SetAbsoluteExpiration(TimeSpan.FromSeconds(60));//设置绝对过期时间 var result = _cache.GetString(CacheName); if (result == null) { result = CacheValue; _cache.Set(CacheName, Encoding.UTF8.GetBytes(CacheValue), options); } return result; }
基本操作完成!
