HTTP multipart response using Perl


Is it possible to provide HTTP multipart response just like multipart request? The scenario is like, I would like to provide a URL which takes a parameter for EmployeeID, and in return the response should consist of employee's photo, latest payslip and information like name, age and address. The receiving end is not a browser, but it will be a program which gets this response and process them later. Any idea on how to do this?

To give more information on my above question, I have to provide a URL to my friend who will programmatically receive the response. For e.g.:

$response = $ua->request($my_url)

My application is supposed to respond with not just data, but also with files! I was being asked to make it to return multipart response.


Solution

  • I'm posing my original https://gist.github.com/1391017 as response.

    #!/usr/bin/perl
    use strict;
    use warnings;
    
    use HTTP::Response;
    
    my $response = HTTP::Response->new(
        200, 'OK', [ 'Content-Type' => 'multipart/form-data' ]
    );
    
    $response->protocol('HTTP/1.1');
    $response->date(time);
    $response->server('Foo/1.0');
    
    my $name = HTTP::Message->new([
        'Content-Type'        => 'text/plain; charset=UTF-8',
        'Content-Disposition' => 'form-data; name="name"',
    ], 'John Doe');
    
    $response->add_part($name);
    
    my $note = HTTP::Message->new([
        'Content-Type'        => 'text/plain; charset=UTF-8',
        'Content-Disposition' => 'form-data; name="note"',
    ], <<'NOTE');

      o http://tools.ietf.org/html/rfc2388
      o http://tools.ietf.org/html/rfc2616
    NOTE
    
    $response->add_part($note);
    
    my $blob = HTTP::Message->new([
        'Content-Type'        => 'application/octet-stream',
        'Content-Disposition' => 'form-data; name="blob"; filename="blob.bin"',
    ]);
    $blob->add_content('a chunk');
    $blob->add_content(' of data');
    
    $response->add_part($blob);
    
    print $response->as_string;
    

    Output:

    HTTP/1.1 200 OK
