k2hdkc_go's Introduction

k2hdkc_go

Overview

k2hdkc_go implements a k2hdkc client in golang.

Install

Firstly you must install the k2hdkc shared library.

$ curl -o- https://raw.github.com/yahoojapan/k2hdkc_go/master/cluster/start_server.sh | bash

You can install k2hdkc library step by step from source code. See Build for details.

After you make sure you set the GOPATH environment, download the k2hdkc_go package.

$ go get -u github.com/yahoojapan/k2hdkc_go

Usage

Here is a simple example of k2hdkc_go which save a key and get it.

package main

import (
	"fmt"
	"os"

	"github.com/yahoojapan/k2hdkc_go/k2hdkc"
)

func setAndGet() {
	c := k2hdkc.NewClient("../../cluster/slave.yaml", 8031)
	defer c.Close()
	// save a hello key.
	if r, err := c.Set("hello", "world"); r == nil || err != nil {
		fmt.Fprintf(os.Stderr, "client.Set(key, value) returned r %v err %v\n", r, err)
		return
	}
	// get the key.
	r, err := c.Get("hello")
	if r == nil || err != nil {
		fmt.Fprintf(os.Stderr, "client.Get(key) returned r %v err %v\n", r, err)
		return
	}
	fmt.Println(r.String())
}

func main() {
	setAndGet()
}
