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 ~~~ 2：使用 ~~~ import "github.com/bradfitz/gomemcache/memcache" ~~~ 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) } } ~~~
