Why don't you use the functions of the upload object to store the uploaded file?
I have tried the following code:
put '/upload/:file' => sub {
my $upload_dir =
"c:/Fotis/INA-CERTH/Microme/PathTrace/WebApp/PathTraceWS/UPLOADS";
my $filename = params->{file};
my $uploadedFile = request->upload($filename);
$uploadedFile->copy_to('$upload_dir');
debug "My Log 1: " . params->{file};
debug "My Log 2: " . ref($uploadedFile);
return "DONE";
};
However, the problem is probably the same as before:
/
//request to PUT /upload/test crashed: Can't call method "copy_to" on an
undefined value/
What I really cannot understand is why the second debug line returns empty
(...ref($uploadedFile)...).
Also you open the file for reading, not for writing.
Well that's embarrassing... However, I corrected it and the problem remains
(for some reason, it doesn't get the file).
Thank you very much for your time!
Regards,
Fotis
