如何使用Go語言高效處理大量圖片的上傳和替換任務(wù)？

content="@@##@@</img>@@##@@</img>"

func upload(url string) string {     // 創(chuàng)建ossclient實例。     client, err := oss.new(endpoint, key, Accesskeysecret)     if err != nil {         fmt.println("error:", err)         os.exit(-1)     }     t1 := time.now().unix()     if ti1 != t1 { //如果時間戳不一樣,那么歸零         long = 0     }     ti1 = t1     long++     obj := fmt.sprintf("article/%d%d.png", t1, long)     // 獲取存儲空間。     bucket, err := client.bucket(bucketname)     if err != nil {         fmt.println("error:", err)         os.exit(-1)     }      // 上傳byte數(shù)組。     err = bucket.putobject(obj, bytes.newreader(readimgdata(url)))     if err != nil {         fmt.println("error:", err)         os.exit(-1)     }     return "https://" + bucketname + "." + endpoint + "/" + obj }  func repimages(htmls string) string {     var imgre = regexp.mustcompile(`@@##@@</img>]+bsrc=["']([^"']+)["']`)     imgs := imgre.findallstringsubmatch(htmls, -1)     out := make([]string, len(imgs))     myimage := ""     reshtml := htmls     for i := range out {         if ! strings.hasprefix(imgs[i][1], "https://static.images.net") {             myimage = upload(imgs[i][1])             reshtml = strings.replace(reshtml, imgs[i][1], myimage, -1)             out[i] = imgs[i][1]             fmt.println(strconv.itoa(i), out[i])         }     }     fmt.println(reshtml)     return reshtml }  func main() {     content := "@@##@@</img>@@##@@</img>"     repimages(content) }
