Hi Daniel,
Thanks for your reply. I am doing nothing myself with the content
length, indeed I am using HTTP::Request::Common to handle everything.
Here's the test script inline:
#!/usr/bin/env perl
package MyApp;
use strict;
use warnings;
use Dancer2;
use Data::Dumper;
set serializer => 'JSON';
any '/ok' => sub {
return {};
};
any '/nok' => sub {
my $a = request->content;
#print STDERR Dumper $a;
#print STDERR Dumper { params('body') };
return {};
};
# dance();
package main;
use strict;
use warnings;
use Test::More;
use Plack::Test;
use HTTP::Request::Common;
use JSON;
my $app = MyApp->to_app;
isa_ok( $app, 'CODE' );
test_psgi $app, sub {
my $cb = shift;
my $res = $cb->( GET '/ok' );
ok($res->code == 200, "GET route without request->content call");
$res = $cb->( GET '/nok' );
ok($res->code == 200, "GET route with request->content call");
my $json_data = { foo => 'bar' };
$res = $cb->(
POST '/ok',
'Content-Type' => 'application/json',
Content => JSON::to_json($json_data),
);
ok($res->code == 200, "JSON POST to route without request->content
call");
$res = $cb->(
POST '/nok',
'Content-Type' => 'application/json',
Content => JSON::to_json($json_data),
);
# this test fails.
ok($res->code == 200, "JSON POST to route with request->content call");
};
done_testing;
1;

I'm afraid I didn't get the attachment, so apologies if this guess is out, but
are you setting the content-length on your HTTP::Request? If not, have a look
at how HTTP::Request::Common does it -
https://metacpan.org/source/ETHER/HTTP-Message-6.11/lib/HTTP/Request/Common.pm#L97
- (or indeed just use HTTP::Request::Common itself).

Subject: [dancer-users] "Route exception: Bad Content-Length: maybe client
disconnect?" with JSON POST and request->content
Hi all,
I'm running into an issue that looks like a bug, but I'm unsure where it comes
from. Could be in Dancer2, but maybe in Plack::Request, or even in Plack::Test,
HTTP::Request, or somewhere else. I'm kinda lost in the woods. I was hoping
that a mind greater than mine can shed some light on this.
I get an error "Route exception: Bad Content-Length: maybe client disconnect? (xx
bytes remaining)" where xx is the total content length of the request body.
But only under the following conditions:
- (valid) JSON POST to a Dancer2 app
- the app is configured with serializer = JSON
- in the route there's a call to: request->content
- using Plack::Test and HTTP::Request
Attached is a minimal test to demonstrate the issue. Test no 5 fails.
I cannot reproduce this issue when using f.e. curl, this call works without
errors:
curl --data-binary '{ "foo": "123" }' --header 'Content-type:
application/json' http://localhost:3000/nok
I am using the latest version of Dancer (0.200003) and also latest CPAN
versions of Plack and HTTP::Request.
Any insights?
Thanks,
Lennart
