我昨天在Perl Monks上发布了这个问题,但它适用于所有尝试它的人(见
http://www.perlmonks.org/?node_id=909968).但是,我使用的是不同的URL,希望能够简化问题.
我正在尝试通过HTTPS连接到api.betfair.com,他们有一个我在浏览器中验证过的有效证书.我正在运行ubuntu并有2个版本的Perl.一个5.10.0工作的系统和通过perlbrew安装的5.14.0失败.代码是：
use LWP::UserAgent;
use strict;
use warnings;
#$ENV{HTTPS_CA_FILE} = "/usr/share/ca-certificates/cacert.org/cacert.org.crt";
my $ua = LWP::UserAgent->new;
my $req = HTTP::Request->new(GET => 'https://api.betfair.com');
my $res = $ua->request($req);
print $res->headers_as_string;
print $res->content;
在系统Perl 5.10.0下运行它可以正常工作,我得到：

在Perl 5.14.0下运行我得到：
Content-Type：text / plain
客户日期：2011年6月17日星期五08:34:30 GMT
客户警告：内部响应
无法连接到api.betfair.com:443
如果我取消注释HTTPS_CA_FILE的设置并在5.14.0中重新运行,我会得到：
Content-Type: text/plain Client-Date: Fri,17 Jun 2011 08:35:09 GMT Client-Warning: Internal response Can't connect to api.betfair.com:443 (certificate verify Failed) LWP::Protocol::https::Socket: SSL connect attempt Failed with unknown errorerror:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify Failed at /home/martin/perl5/perlbrew/perls/perl-5.14.0/lib/site_perl/5.14.0/LWP/Protocol/http.pm line 51.
我在版本20110409安装了Mozilla :: CA.Mozilla :: CA :: SSL_ca_file()返回“/home/martin/perl5/perlbrew/perls/perl-5.14.0/lib/site_perl/5.14.0/Mozilla/CA /cacert.pem“它存在并且可以被我读取.我在Perl 5.14.0中使用LWP 6.02,在Perl 5.10.0中使用5.836.我读取设置HTTPS_DEBUG = 1应输出一些调试信息,但它只在使用Perl 5.10.0而不是5.14.0时这样做(对我而言).
我不是一个SSL大师,但我尝试了一些我发现的东西,它们让我更加困惑：

DONE
更新：我认为这是因为我设置了PERL_UNICODE = SAL但是未设置这不能解决问题.
更新：版本：
Linux ubuntu 10.10代号为maverick
openssl 0.9.80(我相信最新的ubuntu发行版
解决方法
$openssl s_client -connect api.betfair.com:443 < /dev/null > api.betfair.com.pem $openssl x509 -in api.betfair.com.pem -issuer_hash eb99629b
好吧,whaddayasay,这是同样愚蠢的中间证书0xeb99629b我以前见过与其他人失踪,详见comment above以及如何获得它.
出于好奇,您运行的是什么版本的OpenSSL和ca-certificate？你的系统版本/供应商是什么？
