GoFrame框架garray并发安全数组使用开箱体验

func commonSendMessage(goodsIds *garray.IntArray, messageType int) {

   for _, chunkedGoodsIds := range goodsIdsChunk {

      message.SendMessage(chunkedGoodsIds, messageType, 0) //商品变动appid为0
   }
}

   // 添加数据项
   for i := 0; i < 10; i++ {

   // 获取当前数组长度

   // 获取当前数据项列表
   fmt.Println(a.Slice())
   // 获取指定索引项
