golang操作memcached 转自https://blog.csdn.net/weixin_37696997/article/details/78760397

go使用memcached需要第三方的驱动库，这里有一个库是memcached作者亲自实现的，代码质量效率肯定会有保障
1：安装

go get github.com/bradfitz/gomemcache/memcache
1
2：使用

import "github.com/bradfitz/gomemcache/memcache"
1
3：一个栗子

package main

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

var (
server = "127.0.0.1:11211"
)

func main() {
//create a handle
mc := memcache.New(server)
if mc == nil {
fmt.Println("memcache New failed")
}

//set key-value
mc.Set(&memcache.Item{Key: "foo", Value: []byte("my value")})

//get key's value
it, _ := mc.Get("foo")
if string(it.Key) == "foo" {
fmt.Println("value is ", string(it.Value))
} else {
fmt.Println("Get failed")
}
///Add a new key-value
mc.Add(&memcache.Item{Key: "foo", Value: []byte("bluegogo")})
it, err := mc.Get("foo")
if err != nil {
fmt.Println("Add failed")
} else {
if string(it.Key) == "foo" {
fmt.Println("Add value is ", string(it.Value))
} else {
fmt.Println("Get failed")
}
}
//replace a key's value
mc.Replace(&memcache.Item{Key: "foo", Value: []byte("mobike")})
it, err = mc.Get("foo")
if err != nil {
fmt.Println("Replace failed")
} else {
if string(it.Key) == "foo" {
fmt.Println("Replace value is ", string(it.Value))
} else {
fmt.Println("Replace failed")
}
}
//delete an exist key
err = mc.Delete("foo")
if err != nil {
fmt.Println("Delete failed:", err.Error())
}
//incrby
err = mc.Set(&memcache.Item{Key: "aaa", Value: []byte("1")})
if err != nil {
fmt.Println("Set failed :", err.Error())
}
it, err = mc.Get("foo")
if err != nil {
fmt.Println("Get failed ", err.Error())
} else {
fmt.Println("src value is:", it.Value)
}
value, err := mc.Increment("aaa", 7)
if err != nil {
fmt.Println("Increment failed")
} else {
fmt.Println("after increment the value is :", value)
}
//decrby
value, err = mc.Decrement("aaa", 4)
if err != nil {
fmt.Println("Decrement failed", err.Error())
} else {
fmt.Println("after decrement the value is ", value)
}
}
