使用NTLM身份验证在Pe​​rl中使用.NET Web服务

Question

我试图从Perl脚本调用.NET SOAP Web服务，如下所示。

#!/usr/bin/perl -w
use strict;
use SOAP::Lite 'trace', 'debug';
use Authen::NTLM;
use Data::Dumper;

my $user = '\\username';
my $pass = 'password';
my $host = 'host.example.com:80';

# enable NTLMv2 in Authen::NTLM
ntlmv2(1);


my $soap = SOAP::Lite
    -> uri('http://application.dept.example.com')
    -> proxy('http://host.example.com/app/services/request.asmx', keep_alive => 1, credentials => [$host, '', $user, $pass])
    -> on_action(sub { join '/', 'http://application.dept.example.com', $_[1] })# needed for .NET
    -> readable(1)
    ;

my $som = $soap->GetData(
    SOAP::Data->name(ID => 1234)
);
die $som->faultstring() if defined $som->fault();
my @result = $som->dataof('//GetResponse/GetResult');

foreach my $data (@result) {
    my $item = $data->attr;
    print Dumper($item);
}

然而，当我执行这个脚本时，我得到了这个输出。你会发现我没有结果。

$VAR1 = {};

我已经确认这项服务确实有效 - 所以问题出在我的脚本上。我对使用网络服务非常陌生，所以任何指导都会受到赞赏。

如果查看返回的数据，//GetResponse/GetResult引用的节点是空元素

<GetResponse xmlns="http://application.dept.example.com/">
  <GetResult />
</GetResponse>

所以你的程序正确地找到元素并且什么都不显示
