ProFormUploadButton Upload.LIST_IGNORE 不生效？

Question

 const beforeUpload = (file: RcFile, _: RcFile[]) => {
   const isSizeValid = file.size / 1024 / 1024 < 1;

   if (!isSizeValid) {
     formRef.current?.setFieldsValue({
       descImgUrl: [],
     });
     message.error('只允许上传大小为1MB以内的图片');
   }

   return isSizeValid || Upload.LIST_IGNORE;
 };

还是会有图片显示，怎么能不显示fileList 呀啊！

Answer 1

const beforeUpload = (file: RcFile, _: RcFile[]) => {
  return new Promise((resolve, reject) => {
    const isSizeValid = file.size / 1024 / 1024 < 1;

    if (!isSizeValid) {
      message.error('只允许上传大小为1MB以内的图片');
      reject(new Error('文件太大'));
    } else {
      resolve(file);
    }
  });
};
