ant.design上传问题：Upload file.status is always being uploading

file状态一直未uploading
对于受控模式，你应该在 onChange 中始终 setState fileList，保证所有状态同步到 Upload 内。类似这里的写法：比如

// good

onFileChange(fileList) {
  if ( ... ) {
    ...
  } else {
    ...
  }
  // always setState
  this.setState({ fileList: [...fileList] });
}
