golang 切片批量删除元素

func replaceImage(images []*pb.IMAGES, req *pb.QueryCardImgPcdRequest) {

   for k, v := range images {
      v.Http = strings.ReplaceAll(v.Http, "\u0026", "&")
      if req.CameraOrientation != "" && v.ImageOrientation != req.CameraOrientation {
         images = append(images[:k], images[k+1:]...)
      }
   }
}

报错：runtime error: slice bounds out of range [6:4]

原因：删除多个元素的时候会报错

改为
 

func replaceImage(images []*pb.IMAGES, req *pb.QueryCardImgPcdRequest) {
   kk := 0
   for _, v := range images {
      v.Http = strings.ReplaceAll(v.Http, "\u0026", "&")
      if req.CameraOrientation != "" && v.ImageOrientation != req.CameraOrientation {
         //images = append(images[:k], images[k+1:]...)
         images[kk] = v
         kk++
      }
   }
   images = images[:kk]
}
