antd's Upload component, I want to not upload the file immediately after selecting it, but upload it together after I press the save button. How to do this?

Answer 1

• Use beforeUpload to store the things to be uploaded in the store (state can also be used), and finally return false to prevent uploading.

    <Dragger
        name="ver_file"
        action="version_add"
        showUploadList
        disabled={activeRow.id !== 0}
        fileList={fileList}
        onRemove={() => {
          // 清空文件列表
          dispatch({
            type: 'SystemSettings/Version/changeFileList',
            payload: {
              file: {},
              fileList: [],
            },
          });
        }}
        beforeUpload={(curFile, curFileList) => {
          // 将上传的东西存到store里，返回false阻止上传
          dispatch({
            type: 'SystemSettings/Version/changeFileList',
            payload: {
              file: curFile,
              fileList: curFileList,
            },
          });
          return false;
        }}

• When submitting, append file to FormData

    const data = new FormData();
    // 循环把字段全部加进去
    Object.entries(values).forEach((item) => {
      data.append(item[0], item[1] || '');
    });
    data.append('ver_file', file);
    dispatch({
      type: 'SystemSettings/Version/submitData',
      payload: data,
    });

After you select the file, base64 will be displayed. Just save it together when you click Save
