How to convert curl authentication method to perl

newperldeveloper has asked for the wisdom of the Perl Monks concerning the following question:

I have a curl command curl --cert ~/Desktop/file.pfx:secret_key --cert-type P12 The above will return a a json object. How would I go about achieving the same results in perls. I've tried using
use LWP::UserAgent qw(); require LWP::Protocol::https; my $ua = LWP::UserAgent->new; $ua->ssl_opts( SSL_ca_file => '/Downloads/file.pfx', ); my $test = $ua->post('');
This returns a 500 error.

    SSL_ca_file is for specifying the CA cert file. You want instead to specify your Client cert file and key. Take a look at the SSL_cert_file section of for some examples and try taking it from there.

      Here is what I have so far and the error I have encountered.
      my $client = IO::Socket::SSL->new( # where to connect PeerHost => "example/gettoken", PeerPort => "https" SSL_cert_file => $cert_file, # typical CA file on BSD SSL_passwd_cb => sub {"secret_key"}, ) or die "failed connect or ssl handshake: $!,$SSL_ERROR"; # send and receive over SSL connection print $client "GET / HTTP/1.0\r\n\r\n"; print <$client>;
      The above code give an error failed connect or ssl handshake: Invalid argument,IO::Socket::IP configuration failed When I comment out peerhost and port I nothing happens. Not sure what to do next. When I print dumper is outputs $VAR1 = bless( \*Symbol::GEN0, 'IO::Socket::SSL' ); Any help is greatly appreciated.
        PeerHost => "example/gettoken"

        This does not look right. PeerHost should be a hostname, not some URL or whatever you think example/gettoken is.

    If the code you show is supposed to be what the Curl command does, you have an inconsistency there. You are trying two different files:


    is very different from


    If the :secret_key in your Curl command means that the file is password protected, you will have to look at how IO::Socket::SSL or Net::SSLeay handle this, depending on which backend your code uses. For IO::Socket::SSL, see the SSL_passwd_cb callback.

      Fixed that error after uploading. Still get same results. I will check out IO::Socket and NET::SSLeay. Thanks
