getcds 是一个把etcd中的directory直接映射到struct的工具
1、getcds 只实现了 unmarshal，未实现marshal(struct->etcd directory) 2、struct中只允许使用int、int64、string、struct
安装getcds
go get github.com/coreos/go-etcd/etcd
go get github.com/jinuljt/getcds
使用getcds
// 定义struct
var S struct {
I32 int `etcd:"i32"`
I64 int `etcd:"i64"`
Str string `etcd:"str"`
S struct {
I32 int `etcd:"i32"`
I64 int `etcd:"i64"`
Str string `etcd:"str"`
} `etcd:"s"`
}
machines := []string{"http://192.168.1.58:2379"}
client := NewClient(machines)
defer client.Close()
if err := client.Unmarshal("/test", &S); err != nil {
fmt.Println("getcd unmarshal error due to", err)
}
