AnyEvent::HTTP not sending ContentLength ?

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

This is how it's supposed to work, isn't it ?

my %headerArray = (
"Content-Length"=>2345
);
http_request "PUT" => $url,
              headers=>%headerArray,
              body=>$content,
              sub {do stuff here};
[download]

The problem I'm having is that the request goes through and the other side says "411. The request must be chunked or have a content length." The content size definitley matches the size of the body being sent.

I can't see a simple way to turn on tracing in AnyEvent::HTTP either, which isn't helping my debugging.

The docs for AnyEvent::HTTP (which I haven't used) show the headers being passed in to `http_request()` as a reference to a hash, not the hash itself. Try: `my $headers = { Content-Length => 2345, }; http_request 'PUT' => $url, 'headers' => $headers, ...` [download] I can't see a simple way to turn on tracing in AnyEvent::HTTP either, which isn't helping my debugging. Maybe setting `$ENV{ PERL_ANYEVENT_VERBOSE }` see http://search.cpan.org/~mlehmann/AnyEvent-7.12/lib/AnyEvent.pm#ENVIRONMENT_VARIABLES The way forward always starts with a minimal test.

my $headers={} did the trick. Thanks ! Also thanks to the debug pointer.	[reply]

%headerArray gets expanded out in this list context, resulting in: `http_request "PUT" => $url, headers=> "Content-Length"=>2345, body=>$content, sub {do stuff here};` [download] which is bad syntax. Don't have time to research the right syntax now... This is not an optical illusion, it just looks like one.	[reply] [d/l]

`%headerArray`, as you use it, is a flat list. What you want to pass is a hash reference, thus: `http_request "PUT" => $url, headers=>\%headerArray, body=>$content, sub {do stuff here};` [download] Note the backslash before the percent sign.	[reply] [d/l] [select]
