Hi,

I think I found out what the problem was (PUT vs POST error). This is the new (working) code:

post '/upload/:file' => sub {

my $upload_dir = "MyApp/UPLOADS";
my $filename = params->{file};

my $uploadedFile = upload('file_input_foo');
$uploadedFile->copy_to("$upload_dir/$filename");
};

Thank you all for your time and responses!

Regards,

Fotis

Dear all,

I am quite new to Dancer but I am really amazed on how few lines of code
I have to write for the same functionality (still exploring though).

However, I have hit the following issue: I am trying to upload a file
using the following code:

put '/upload/:file' =>  sub {
      my $upload_dir = "MyApp/UPLOADS";
      my $filename = params->{file};
      my $uploadedFile = request->upload($filename);

Are you sure you don't mean

       my ($uploadedFile) = request->upload('file');

(because the uploads are keyed by the parameter name, not the filename -
but I could be wrong, I'm not very familiar with Dancer, myself.)

      debug "My Log 1: " . params->{file};
      debug "My Log 2: " . ref($uploadedFile);

      open ( UPLOADFILE, "$upload_dir/$filename" ) or die "$!";

      while ( <UPLOADFILE> )
      {
          print UPLOADFILE;
      }

      close UPLOADFILE;

      return "DONE";
};

The PUT command is done via cURL as follows:

curl --upload-file test http://localhost:3000/upload/test
DONE

The output that I see in the "development dance floor" is the following:

[9072]  core @0.000341> request: PUT /upload/test from 127.0.0.1 in

[9072]  core @0.015854> [hit #1]response: 200 in
/Perl/site/lib/Dancer/Handler.pm l. 179

The problem is that the file is created with the correct name in the
correct folder (MyApp/UPLOADS/test) but it is always empty (0 size). No
other warnings or errors, but I do see an issue in the output (marked in
bold - 2nd custom debug line). Any ideas?

Thank you in advance for your time!

Regards,

Fotis
