我使用LWP::UserAgent version 6.03获取网站的地位。错误：500无法连接到foo.com:443（未知errorerror：140773F2：SSL例程：SSL23_GET_SERVER_HELLO：SSLv3）和
my $ua = LWP::UserAgent->new(ssl_opts => {verify_hostname => 0},);
$ua->cookie_jar({});
$ua->agent('Mozilla/5.0');
push @{$ua->requests_redirectable}, 'POST';
push @{$ua->requests_redirectable}, 'GET';
my $url = 'https://foo.com'
$page = $ua->get($url);
print "Error ".$page->status_line."\n";
当我在unix机器上运行此代码时，它给出了LWP模块的以下状态和错误消息。
#status
500 Can't connect to foo.com:443
#error
LWP::Protocol::https::Socket: SSL connect attempt failed with unknown

我试图使用回答given to similar question，但它没有解决。需要你的宝贵意见。

请提供您正在使用的依赖模块（可能是IO :: Socket :: SSL）的URL和版本，并且最好使用openssl的版本。你需要一个代理吗？ –
IO :: Socket :: SSL-> VERSION： 'Version1.54' –
请使用'perl -MIO :: Socket :: SSL = debug4 app.pl'运行你的代码来启用调试。为了更好地帮助提供OpenSSL版本（'perl -MIO :: Socket :: SSL -e'printf'％x \ n“，Net :: SSLeay :: OPENSSL_VERSION_NUMBER（）''。除非它失败了所有的URL如果你希望得到帮助，也可以更好地提供目标主机。现在猜测是它与SNI有关，它只能在1.56之后才可用。 –
