How Upload file using Mojolicious?

Question

I have been trying out Mojolicious web framework based on perl. And I have try to develop a full application instead of the Lite. The problem I am facing is that I am trying to upload files to server, but the below code is not working.

Please guide me what is wrong with it. Also, if the file gets uploaded then is it in public folder of the application or some place else.

Thanks in advance.

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.');
}

I do see that in the Mojolicious::Lite documentation the call to `$self->req->upload()` is wrapped in an `if()`, which means its return value is being checked before assuming there was an upload. Doing so is the equivalent of checking the return value of open, I suppose. — DavidO, Apr 14 '12 at 15:10

(First, you need some HTML form with method="post" and enctype="multipart/form-data", and a input type="file" with name="upload". Just to be sure.)

If there were no errors, $fileuploaded would be a Mojo::Upload. Then you could check its size, its headers, you could slurp it or move it, with $fileuploaded->move_to('path/file.ext').

Taken from a strange example.

Thanks menozero, the HTML part is same as you have mentioned. And I have gone through the link provided, but it is developing based on the Mojolicious::Lite and full application. And in my case `$fileuploaded` is having empty value, so I am not very sure what is currently going wrong. – Kunal Jha Apr 16 '12 at 06:50
Works perfectly fine for me. Thanks a lot menozero! This should be accepted as the solution by Kunal Jha. The problem from him is somewhere else... – Boris Däppen Nov 08 '12 at 14:10
Which library should I look at for serving files to be downloaded? – user1876508 Feb 15 '13 at 02:03

To process uploading files you should use $c->req->uploads

post '/' => sub {
   my $c = shift;
   my @files;
   for my $file (@{$c->req->uploads('files')}) {
     my $size = $file->size;
     my $name = $file->filename;

     push @files, "$name ($size)";
     $file->move_to("C:\\Program Files\\Apache Software Foundation\\Apache24\\htdocs\\ProcessingFolder\\".$name);
   }
   $c->render(text => "@files");
} => 'save';

According to the documentation you linked, RenderFile is for streaming downloads, not uploads. – Esoteric Screen Name Apr 25 '13 at 15:09
