Perl – LWP :: UserAgent第2部分出现500错误

我一直在通过LWP :: UserAgent研究HTTPS 500错误的问题.我在 500 error with LWP:UserAgent尝试了一切都无济于事.

我在同一台服务器上有两个Perl库(系统和我自己的).我自己的图书馆是最新的,但不起作用.

Perl v 5.10.1
IO::Socket::SSL v 2.022
LWP::UserAgent v 6.15
LWP::Protocol::https v 6.06

所有都大于参考文章中推荐的内容.

当我带着跟踪运行时,我得到:

我使用了数据包捕获并发现它使用安全套接字层 – > SSL记录层.较旧的系统库使用安全套接字层 – > TLSv1记录层.失败的包是> 254字节,但我使用更新的Perl代码.

我已经尝试了verify_hostname 0和1没有任何变化.
我试过SSL_Version => TLSv1没有变化.

这是代码:

#!/usr/bin/perl

use strict;
use warnings;

use lib '/opt/mylib/lib/perl5';

use Data::Dumper;
use LWP::UserAgent;
use HTTP::Request;
use JSON;

use Net::SSLeay;
$Net::SSLeay::trace = 2;
$Net::SSLeay::ssl_version = 10;  #-- force TLSv1

use IO::Socket::SSL;
$IO::Socket::SSL::DEBUG = 3;

use constant {
    TOKEN              => 'xxxx-yyyy-aaaa',GET_URI   => 'https://support.myvendor.com',};

my $useragent = LWP::UserAgent->new( ssl_opts => { verify_hostname => 0 },cookie_jar => {} );
$useragent->proxy ('https','https://my.proxy.com:443');
$useragent->ssl_opts( SSL_version => 'TLSv1');

sendRequest ('MyData');

exit 1;

sub sendRequest {
    my ($data) = @_;
    my $request = HTTP::Request->new('POST',GET_URI);
    $request->header('Content-Type' => 'application/json');
    my $json = encode_json {
        'Token' => TOKEN,'Data' => $data
    };
    $request->content($json);
    my $response = $useragent->request($request);
    if (!$response->is_success) {
        print Data::Dumper->Dump([$response],[qw($response)]);
        return;
    }

    eval { $json = decode_json $response->content; 1 } or do {
        print Data::Dumper->Dump([$response],[qw($response)]);
        return;
    };

    print Data::Dumper->Dump([$json],[qw($json)]);
    return;
}

我无法弄清楚这一点.请帮忙

如果我设置SSL_hostname =“”,这就是我得到的:

如果我没有设置SSL_hostname,这就是我得到的.请注意,SNI主机名是
我的代理人 – 是吗?它不应该是最终主机吗?

经过更多的研究,我发现我有verify_hostname => 1当我设置SSL_hostname =”时.我尝试使用verify = 0并稍微进一步.我想这意味着我能够通过我的代理并与终端服务器通信?它仍然不像旧库那样工作.

','_rc' => 500,

解决方法

没有解决方案,但也许是一种解决方法:尝试使用curl而不是libwww,例如 WWW::CurlLWP::Curl(看起来它与LWP :: UserAgent具有相同的界面)

很赞哦! ()
