    uploading: false,
  };

  handleUpload = () => {
    const { fileList } = this.state;
    const formData = new FormData();
    fileList.forEach(file => {
      formData.append('files[]', file);
    });

    this.setState({
      uploading: true,
    });

    // You can use any AJAX library you like
    reqwest({
