驻马店重点项目建设网站,收录平台,长春优化,移动端前端开发需要学什么1、这两天研究Redis搞分布式session问题#xff0c;网上找的资料都是用ServiceStack.Redis来实现的#xff0c;但是在做性能测试的时候发现最新的v4版本有限制每小时候最多请求6000次#xff0c;因为官网开始商业化要收费了#xff0c;好坑爹的说#xff0c;还好我前期弄了…1、这两天研究Redis搞分布式session问题网上找的资料都是用ServiceStack.Redis来实现的但是在做性能测试的时候发现最新的v4版本有限制每小时候最多请求6000次因为官网开始商业化要收费了好坑爹的说还好我前期弄了个性能测试列子不然上线以后出问题那就麻烦了。后面找了个NServiceKit.Redis好像就是ServiceStack.Redis的v3版本来替代v4的收费版。 2、解决方案是 Rediscookie方式实现记录用户登录状态 cookie存放用户的ID这个ID是经过加密的并且后台可以通过密钥解密。 Rediskey/value 方式存储key存放比如user_1。 value存放用户实体对象。 3、先安装一个Rediswindows的版本在本地进行测试后期上线更换linux系统的Redis替换一下ip就可以了。 4、添加一个Session管理类 public class SessionHelper{private const int secondsTimeOut 60 * 20; //默认过期时间20分钟 单位秒public RedisHelper Redis new RedisHelper(false);public LoginUserInfo this[string key]{get{string webCookie WebHelper.GetCookie(key);if (webCookie ){return null;}key key _ SecureHelper.AESDecrypt(webCookie);//距离过期时间还有多少秒long l Redis.TTL(key);if (l 0){Redis.Expire(key, secondsTimeOut);}return Redis.GetLoginUserInfo(key);}set{SetSession(key, value);}}public void SetSession(string key, LoginUserInfo value){if (string.IsNullOrWhiteSpace(key)){throw new Exception(Key is Null or Epmty);}WebHelper.SetCookie(key, SecureHelper.AESEncrypt(value.ID.ToString()));key key _ value.ID;Redis.SetLoginUserInfo(key, value, secondsTimeOut);}/// summary/// 移除Session/// /summary/// param namekey/param/// returns/returnspublic bool Remove(string key){var rs Redis.Remove(key _ SecureHelper.AESDecrypt(WebHelper.GetCookie(key)));WebHelper.DeleteCookie(key);return rs;}} 5、Redis操作类 public class RedisHelper : IDisposable{private RedisClient Redis new RedisClient(127.0.0.1, 6379);//缓存池PooledRedisClientManager prcm new PooledRedisClientManager();//默认缓存过期时间单位秒public int secondsTimeOut 20 * 60;/// summary/// 缓冲池/// /summary/// param namereadWriteHosts/param/// param namereadOnlyHosts/param/// returns/returnspublic static PooledRedisClientManager CreateManager(string[] readWriteHosts, string[] readOnlyHosts){return new PooledRedisClientManager(readWriteHosts, readOnlyHosts,new RedisClientManagerConfig{MaxWritePoolSize readWriteHosts.Length * 5,MaxReadPoolSize readOnlyHosts.Length * 5,AutoStart true,}); }/// summary/// 构造函数/// /summary/// param nameOpenPooledRedis是否开启缓冲池/parampublic RedisHelper(bool OpenPooledRedis false){if (OpenPooledRedis){prcm CreateManager(new string[] { 127.0.0.1:6379 }, new string[] { 127.0.0.1:6379 });Redis prcm.GetClient() as RedisClient;}}/// summary/// 距离过期时间还有多少秒/// /summary/// param namekey/param/// returns/returnspublic long TTL(string key){return Redis.Ttl(key);}/// summary/// 设置过期时间/// /summary/// param namekey/param/// param nametimeout/parampublic void Expire(string key,int timeout 0){if (timeout 0){if (timeout 0){secondsTimeOut timeout;}Redis.Expire(key, secondsTimeOut);}}#region Key/Value存储/// summary/// 设置缓存/// /summary/// typeparam nameT/typeparam/// param namekey缓存建/param/// param namet缓存值/param/// param nametimeout过期时间单位秒,-1不过期0默认过期时间/param/// returns/returnspublic bool SetT(string key, T t, int timeout 0){Redis.SetT(key, t);if (timeout 0){if (timeout 0){secondsTimeOut timeout;}Redis.Expire(key, secondsTimeOut);}return true;}/// summary/// 获取/// /summary/// typeparam nameT/typeparam/// param namekey/param/// returns/returnspublic T GetT(string key){return Redis.GetT(key);}/// summary/// 删除/// /summary/// param namekey/param/// returns/returnspublic bool Remove(string key){return Redis.Remove(key);}#endregion//释放资源public void Dispose(){if (Redis ! null){Redis.Dispose();Redis null;}GC.Collect();}} 转载于:https://www.cnblogs.com/valen/p/4655427.html
