Perl LWP :: UserAgent，https到特定https网站的代理，未知协议错误

时间：2015-01-09 00:31:26

标签： perl proxy

阅读我能找到的有关主题的所有内容......无法确定如何使其成功。

我使用新更新的（2015年1月9日）Active State Perl和标准方法

my $ua=LWP::UserAgent->new();  
$ua->agent('Mozilla/5.0 (Windows NT 6.1; WOW64; rv:34.0) Gecko/20100101 Firefox/33.0');
$ua->timeout(120);
$ua->cookie_jar( {} );
$ua->proxy(['https'],'https://199.200.120.140:8089') #taken from http://proxylist.hidemyass.com/search-1308872#listable
my $response = $ua->get('https://www.comparis.ch');   #this web site I struggle with, I can connect to https://github.com for example... But I also can connect to comparis.ch through same proxy using urllib3 on Python3.4...

如果有人可以解释如何从网站获得200？

的输出

响应返回Timeout（如果我使用http代理或

） 
LWP::Protocol::https::Socket: SSL connect attempt failed error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol at E:/Perl64/lib/LWP/Protocol/http.pm line 49."

如果我尝试

LWP::UserAgent->new(ssl_opts => { verify_hostname => 0, SSL_version => 'SSLv3' });

然后我

LWP::Protocol::https::Socket: SSL connect attempt failed error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number at E:/Perl64/lib/LWP/Protocol/http.pm line 49.

我认为该网站会在某些地区超时连接，因此必须使用来自美国或西欧的代理服务器。

根据要求我添加了调试输出（对于简单的UserAgent-＆gt; new（） - 无选项），它从http://proxylist.hidemyass.com/search-1305502#listable尝试两个代理192.3.121.204:3128和64.31.22.131:7808。第一个似乎只是超时（很可能被阻止），但第二个表现出不同的行为。

在Stefan建议之后我使用http：//代理地址（而不是https），这产生了一些更好的结果如下，同样，它在Ubuntu下完全有效，但在Windows中却没有...

我想它现在有点不同了，但是我搜索了网页，却找不到任何答案。

答案 0 :(得分：5)

我想我知道你的问题是什么。 当您执行https代理请求时，您没有使用HTTP协议连接到代理，而是使用HTTP协议，然后发出CONNECT请求来构建隧道。因此，代理的网址只能是http://，而不是https://：

$ua->proxy(['https'],'http://199.200.120.140:8089');
                      ^^^^ http:// instead of https://

除此之外，请确保LWP :: UserAgent和LWP :: Protocol :: https至少是版本6.06，因为这些添加了对代理HTTPS流量的适当支持。但我认为这些版本在你的情况下应该是新的。

编辑：由于您在Windows上使用最新版本的IO :: Socket :: SSL运行代码，因此您触发了与Windows中新增添加的对非阻塞SSL套接字的支持相关的错误， ＆＃34;状态读取失败：无法立即完成非阻塞套接字操作＆＃34;。有关详细信息和修复，请参阅https://github.com/libwww-perl/net-http/pull/11。

感谢Steffen，解决方案是https://github.com/libwww-perl/net-http/pull/11 我试过了，它在我的情况下正常工作。
