   我是 windows系统，可以选择非 accept 文件，此时 beforeUpload 还是没有触发的。
   https://github.com/react-component/upload/pull/329/files 看起来没有解决这个问题

   +1 当用户拖入非 accept 的文件，目前是没有任何反应的。我想要弹出message（例如”该类型文件不支持“），好像没法实现。只有onDrop会触发，但onDrop里只有DragEvent，没有file的信息。

   可以在 DragEvent 中拿到 file

   function handleDrop(event: DragEvent) {
     const files = event.dataTransfer?.files;
     if (files) {
       const filesArr = Array.from(files);
       filesArr.forEach((file) => {
         // 校验
       });
     }
   }
