Use Redis to implement the Session Function

RedisIt is an open-source log-type and Key-Value database written in ansi c language that supports the network and can be persistent based on memory. It also provides APIs in multiple languages.

--- Wikipedia

InProc mode is easy to lose and causes concurrency problems. If SQLServer or SQLServer mode is used, performance is consumed.

Redis uses this solution to solve several problems,

1. Fast Redis access.

2. User data is not easy to lose.

3. clusters are easily supported when there are many users.

4. view online users.

5. One user can log on at a time. (Implemented through code and will be introduced later)

6. Support persistence. (Of course it may be useless)

Program needsWhen the user status is obtained, the sessionid is used as the key to search in Redis.

Automatically intercept requests to call this method(Demo has examples)

 

 

Initialize Configuration

 sessionRedis= ConfigurationManager.AppSettings[ timeOut = ConfigurationManager.AppSettings[ (  Exception( (.IsNullOrEmpty(timeOut)=== host = sessionRedis.Split(.Parse( writeHost =  [] { host[ readHosts = host.Skip(=  PooledRedisClientManager(writeHost, readHosts, = writeReadCount,                MaxReadPoolSize = writeReadCount,                AutoStart = 

 

A delegate is written for control convenience.

                                               F TryRedisWrite<F>(Func<IRedisClient, F>= =  (client =  Exception( + client.Host +  + (client != 

For more information about one call example, see the source code.

Methods for accessing users

                                              Get<T>()  T:,  RedisClient<T>                              RedisClient<>                                      Login<T>(T obj)  T : , RedisClient<T>().KSet(SessionId, obj,  TimeSpan(, Managers.TimeOut, 

 

 

 

                                              KSetEntryIn(<IRedisClient, > fun = (IRedisClient client) => 

After Encapsulation

    RedisClient<>().KSetEntryIn(SessionId,  TimeSpan(, Managers.TimeOut, 

 

Here, I use ActionFilter in MVC3 to intercept all user requests.

SessionManager can be used to retrieve the number of users in the user list, deregister a user, and obtain user information, online user object list, and online user SessionId list based on the user ID.

One user login function will be implemented in the future
