| Subject: | Troubles sending binary data via LWP::UserAgent::post |
Hello.
I have following code:
use strict;
use warnings;
use LWP::UserAgent ();
use URI ();
use URI::Escape ();
use Storable ();
use Data::Dumper 'Dumper';
my $value = [ "hi" ];
my $initial_s = URI::Escape::uri_escape( Storable::freeze( $value ) );
print $initial_s . "\n";
my $u = URI -> new( 'http://somedomain/rpc/set?key=123&value=' . $initial_s . '&xt=60' );
my %args = $u -> query_form( undef );
$u = $u -> as_string();
print URI::Escape::uri_escape( $args{ 'value' } ) . "\n";
LWP::UserAgent -> new() -> post( $u, Content_Type => 'application/x-www-form-urlencoded', Content => [ %args ] );
my $s = LWP::UserAgent -> new() -> get( 'http://somedomain/123' ) -> content();
print URI::Escape::uri_escape( $s ) . "\n";
print Dumper( Storable::thaw( $s ) );
exit 0;
which POSTs some binary data to our Kyoto Tycoon server and then retrives it.
In LWP::UserAgent 5.835 this code works well: I am able to POST data, then GET it back, and it is still the same data I've sent initially. But in LWP::UserAgent 6.05 when I'm GETting my data back - it differs from the initial value.
There is no troubles with Kyoto Tycoon as there is no problems LWP::UserAgent::get as I can see, but it seems that there is some trouble with LWP::UserAgent::post because following code works well:
use strict;
use warnings;
use LWP::UserAgent ();
use URI::Escape ();
use Storable ();
use Data::Dumper 'Dumper';
my $value = [ "hi" ];
my $initial_s = URI::Escape::uri_escape( Storable::freeze( $value ) );
print $initial_s . "\n";
my $cmd = 'curl -X POST -s "http://somedomain/rpc/set?key=123&value=' . $initial_s . '&xt=60"';
system( $cmd );
my $s = LWP::UserAgent -> new() -> get( 'http://somedomain/123' ) -> content();
print URI::Escape::uri_escape( $s ) . "\n";
print Dumper( Storable::thaw( $s ) );
exit 0;
And, of course, as well as the code above, following code also work:
use strict;
use warnings;
use LWP::UserAgent ();
use URI::Escape ();
use Storable ();
use Data::Dumper 'Dumper';
my $value = [ "hi" ];
my $initial_s = URI::Escape::uri_escape( Storable::freeze( $value ) );
print $initial_s . "\n";
my $cmd = 'curl -X POST -s "http://somedomain/rpc/set?key=123&value=' . $initial_s . '&xt=60"';
system( $cmd );
my $s = `curl -s -o - http://somedomain/123`;
print URI::Escape::uri_escape( $s ) . "\n";
print Dumper( Storable::thaw( $s ) );
exit 0;
There is a note that initial code failures depend on $initial_s contents. I.e. it fails with serialized [ "hi" ], but works well with [ 1, 2, 3 ].
Could that be fixed somehow, or should I change my code?
