七牛云存储list列出文件简单demo(php版本和golang演示)

看到了七牛官网上很多问list这个API如何用?或者说人们看不懂,我用简单的例子或者demo来简单的给大家看看
这个如何用!一个php版本一个golang的简单demo!

golang版本

package main
import (
 "crypto/hmac"
 "crypto/sha1"
 "encoding/base64"
 "fmt"
 "io/ioutil"
 "net/http"
 "strings"
)
const (
 SK = "D-K57TE5hPe3krexftxLWFKmL2xbQEKA-mtkrUfB"
 AK = "KUN6xYZlOAtid2MjHm90-6VFY2M7HC90ijDH4uOR"
 HOST = "rsf.qbox.me"
)
func main() {
 mac := hmac.New(sha1.New, []byte(SK))
 mac.Write([]byte("/list?bucket=gitwiduu&limit=20\n"))
 a := mac.Sum(nil)
 client := &http.Client{}
 u := base64.StdEncoding.EncodeToString([]byte(a))
 u = strings.Replace(u, "+", "-", -1)
 u = strings.Replace(u, "/", "_", -1)
 request, _ := http.NewRequest("POST", "http://rsf.qbox.me/list?bucket=gitwiduu&limit=20", nil)
 request.Header.Set("Content-Type", "application/x-www-form-urlencoded; param=value")
 request.Header.Set("Host", HOST)
 request.Header.Set("Connection", "keep-alive")
 request.Header.Set("Authorization", "QBox "+AK+":"+u)
 response, _ := client.Do(request)
 if response.StatusCode == 200 {
 data, _ := ioutil.ReadAll(response.Body)
 fmt.Println(string(data))
 }
 fmt.Println("ok")
}

php 版本
