Question

我发现很多问题与我的问题非常相似，但他们并没有解决，所以我在这里寻求你的帮助。

我正在尝试使用https从Perl LWP网页获取数据。我可以从几乎我尝试过的每个网站获取数据，除了我真正需要使用的网站。我在Windows x64下使用Perl版本v5.18.2。这是我的基本虚拟示例：

use strict;
use LWP::UserAgent;
use HTTP::Request;
use IO::Socket::SSL qw(debug3);
my $ua = LWP::UserAgent->new;
my $url = 'https://www.domainx.com:443';
my $req = HTTP::Request->new( GET => $url);
my $response = $ua->request($req);
print $response->status_line . "\n";

响应结果 - ＆gt; status_line： 500 Can't connect to www.domainx.com:443

调试SSL：

DEBUG: .../IO/Socket/SSL.pm:393: socket not yet connected
DEBUG: .../IO/Socket/SSL.pm:395: socket connected

DEBUG: .../IO/Socket/SSL.pm:1932: OK free ctx 48125200

通过查看以前的帖子，我尝试申请：ssl_opts =＆gt; {verify_hostname =＆gt; 0}，但这没有帮助。如果我尝试使用浏览器（IE或Chrome）连接到同一个站点，它可以正常工作。

这是基于证书的错误还是这里出了什么问题？

实际网站是www.firstcard.fi

服务器严重破坏，从report by SSLLabs也可以看到。要获得与服务器的连接，只需使用服务器提供的单个良好密码即可解决这些问题：

my $ua = LWP::UserAgent->new;
$ua->ssl_opts(SSL_cipher_list => 'DES-CBC3-SHA');

有趣的是，这个密码包含在IO :: Socket :: SSL中默认使用的密码列表中，但服务器太破碎而无法正确处理正确的ClientHello。

LWP / IO :: Socket :: SSL因SSL3_GET_SERVER_HELLO而失败：返回了错误的密码
