简单的例子来测试下基本的操作: ~~~ package main /** 客户端doc地址:github.com/samuel/go-zookeeper/zk **/ import ( "fmt" "time" zk "github.com/samuel/go-zookeeper/zk" ) /** * 获取一个zk连接 * @return {[type]} */ func getConnect(zkList []string) (conn *zk.Conn) { conn, _, err := zk.Connect(zkList, 10*time.Second) if err != nil { fmt.Println(err) } return } /** * 测试连接 * @return */ func test1() { zkList := []string{"localhost:2181"} conn := getConnect(zkList) defer conn.Close() var flags int32 = 0 //flags有4种取值: //0:永久,除非手动删除 //zk.FlagEphemeral = 1:短暂,session断开则改节点也被删除 //zk.FlagSequence = 2:会自动在节点后面添加序号 //3:Ephemeral和Sequence,即,短暂且自动添加序号 conn.Create("/go_servers", nil, flags, zk.WorldACL(zk.PermAll)) // zk.WorldACL(zk.PermAll)控制访问权限模式 time.Sleep(20 * time.Second) } /* 删改与增不同在于其函数中的version参数,其中version是用于 CAS支持 func (c *Conn) Set(path string, data []byte, version int32) (*Stat, error) func (c *Conn) Delete(path string, version int32) error demo: if err = conn.Delete(migrateLockPath, -1); err != nil { log.Error("conn.Delete(\"%s\") error(%v)", migrateLockPath, err) } */ /** * 测试临时节点 * @return {[type]} */ func test2() { zkList := []string{"localhost:2181"} conn := getConnect(zkList) defer conn.Close() conn.Create("/testadaadsasdsaw", nil, zk.FlagEphemeral, zk.WorldACL(zk.PermAll)) time.Sleep(20 * time.Second) } /** * 获取所有节点 */ func test3() { zkList := []string{"localhost:2181"} conn := getConnect(zkList) defer conn.Close() children, _, err := conn.Children("/go_servers") if err != nil { fmt.Println(err) } fmt.Printf("%v \n", children) } func main() { test3() } ~~~
