This article mainly explains "what is the principle and mechanism of redis cache storage Session". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is the principle and mechanism of redis cache storage Session".

Storing Session based on Redis

If we want to save session data to redis, we just need to change the storage engine of session to redis.

An example of using redis as a storage engine:

First install the package go get github.com/gin-contrib/sessions/redis// of the redis storage engine to initialize the redis-based storage engine / / Parameter description: / / 1st parameter-redis maximum number of idle connections / / 2nd parameter-numerical communication protocol tcp or udp / / 3rd parameter-redis address, format Host:port / / 4th parameter-redis password / / 5th parameter-session encryption key store, _: = redis.NewStore (10, "tcp", "localhost:6379", "", [] byte ("secret")) r.Use (sessions.Sessions ("mysession") Store)) set session expiration time / / configure the expiration time of session session.Options (sessions.Options {MaxAge:3600*6}) / / 6 hours = 60 / 60 / 6 distributed acquisition Session: (redis)

After the study of this article, I believe you have a deeper understanding of what the principle mechanism of redis cache storage Session is, and the specific use needs to be verified in practice.
