go使用memcache

使用文档：https://godoc.org/github.com/bradfitz/gomemcache/memcache#Client

import (
    "fmt"
    "github.com/bradfitz/gomemcache/memcache"
)

var Client *memcache.Client

const (
    MEMCACHE_HOST = ""
    MEMCACHE_PORT = ""
)

var CacheErr error

func Cache() {
    dsn := fmt.Sprintf("%s:%s", MEMCACHE_HOST, MEMCACHE_PORT)
    Client = memcache.New(dsn)
    // 添加一个key,过期时间为100s
    Client.Add(&memcache.Item{
        Key:        "golang",
        Value:      []byte("test golang memcache"),
        Flags:      0,
        Expiration: 100,
    })
    // 获取一个key
    item1, CacheErr := Client.Get("golang")
    if CacheErr != nil {
        fmt.Println(CacheErr.Error())
    } else {
        fmt.Println(string(item1.Value), item1.Key)
    }
    // 替换一个key，替换掉上面添加的key
    Client.Replace(&memcache.Item{
        Key:        "golang",
        Value:      []byte("replace golang memcache"),
        Flags:      0,
        Expiration: 100,
    })
    // 获取一个key
    item2, CacheErr := Client.Get("golang")
    if CacheErr != nil {
        fmt.Println(CacheErr.Error())
    } else {
        fmt.Println(string(item2.Value), item2.Key)
    }
    // 删除一个key
    CacheErr = Client.Delete("golang")
    if CacheErr != nil {
        fmt.Println(CacheErr.Error())
    } else {
        fmt.Println("删除成功！")
    }
    // 删除全部
    CacheErr = Client.DeleteAll()
    if CacheErr != nil {
        fmt.Println(CacheErr.Error())
    } else {
        fmt.Println("全部删除成功！")
    }

}
