cache is a golang cache manager. It can use cache for many adapters. The repo is inspired by `database/sql` . cache is a Go cache manager. It can use many cache adapters. The repo is inspired by `database/sql` .
##How to install
## How to install?
go get github.com/astaxie/beego/cache go get github.com/astaxie/beego/cache
##how many adapter support
Now this cache support memory/redis/memcache ## What adapters are supported?
## how to use it
first you must import it
As of now this cache support memory, Memcache and Redis.
## How to use it?
First you must import it
import ( import (
"github.com/astaxie/beego/cache" "github.com/astaxie/beego/cache"
) )
then init an Cache(memory adapter) Then init a Cache (example with memory adapter)
bm, err := NewCache("memory", `{"interval":60}`) bm, err := NewCache("memory", `{"interval":60}`)
use it like this: Use it like this:
bm.Put("astaxie", 1, 10) bm.Put("astaxie", 1, 10)
bm.Get("astaxie") bm.Get("astaxie")
bm.IsExist("astaxie") bm.IsExist("astaxie")
bm.Delete("astaxie") bm.Delete("astaxie")
## memory adapter
memory adapter config like this: ## Memory adapter
Configure memory adapter like this:
{"interval":60} {"interval":60}
interval means the gc time. The cache will every interval time to check wheather have item expired. interval means the gc time. The cache will check at each time interval, whether item has expired.
## memcache adapter
memory adapter use the vitess's [memcache](code.google.com/p/vitess/go/memcache) client.
the config like this: ## Memcache adapter
memory adapter use the vitess's [Memcache](http://code.google.com/p/vitess/go/memcache) client.
Configure like this:
{"conn":"127.0.0.1:11211"} {"conn":"127.0.0.1:11211"}
## redis adapter ## Redis adapter
redis adapter use the [redigo](github.com/garyburd/redigo/redis) client.
the config like this: Redis adapter use the [redigo](http://github.com/garyburd/redigo/redis) client.
{"conn":":6039"} Configure like this:
{"conn":":6039"}

##How to write own provider ## How to write own provider?
When we develop a web app, maybe you want to write a provider because you must meet the requirements.
Write a provider is so easy. You only define two struct type(Session and Provider),which satisfy the interface definition.Maybe The memory provider is a good example for you. When you develop a web app, maybe you want to write own provider because you must meet the requirements.
