perl – LWP HTTPS GET上的连接失败或“证书验证失败”

2019年8月3日 229次阅读

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：

Client-Warning: Internal response

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

最佳答案

$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？
