阿里云存储OSS golang语言上传文件示例。

由于阿里那边没有提供golang示例只有自己写一个，如果发现问题希望给予纠正。

配置信息自己替换。

调用方法

Putobject("4.txt", []byte("123123fasdfasdfadfadfasfasdfsadf"))

package oss

import (
	"bytes"
	"crypto/hmac"
	"crypto/sha1"
	"encoding/base64"
	"fmt"
	"io/ioutil"
	"mime"
	"net/http"
	"path/filepath"
	"time"
)


func authorization(accesskeysecret, method, filemd5, filetype, date, CanonicalizedOSSHeaders, CanonicalizedResource string) string {

	h := hmac.New(sha1.New, []byte(accesskeysecret))
	s := fmt.Sprintf("%v\n%v\n%v\n%v\n%v%v", method, filemd5, filetype, date, CanonicalizedOSSHeaders, CanonicalizedResource)
	h.Write([]byte(s))
	return base64.StdEncoding.EncodeToString(h.Sum(nil))
}

var client = &http.Client{Timeout: 20 * time.Second}

func Putobject(key string, b []byte) bool {

	url := fmt.Sprintf("http://%v.%v/%v", config.Cfg.Oss.Bucket, config.Cfg.Oss.Server, key)

	dt := time.Now().UTC().Format("Mon, 02 Jan 2006 15:04:05 GMT")
	ct := mime.TypeByExtension(filepath.Ext(key))

	req.Header.Add("Content-Length", string(len(b)))
