perl – 如何使用Mojolicious上传文件？

请指导我有什么问题.此外,如果文件被上传,那么它在应用程序的公用文件夹或其他地方.

提前致谢.

sub posted {
 my $self = shift;
 my $logger = $self->app->log;

 my $filetype = $self->req->param('filetype');
 my $fileuploaded = $self->req->upload('upload');

 $logger->debug("filetype: $filetype");
 $logger->debug("upload: $fileuploaded");

 return $self->render(message => 'File is not available.')
  unless ($fileuploaded);

 return $self->render(message => 'File is too big.',status => 200)
   if $self->req->is_limit_exceeded;

 # Render template "example/posted.html.ep" with message
 $self->render(message => 'Stuff Uploaded in this website.');
}
