Perl SOAP :: LITE服務生成存根方法內的方法

Question

我有一個SOAP :: Lite客戶端使用服務方法來抓取wsdl。這需要使用不帶參數的單個操作和方法來調用Web服務。這導致了提供者告訴我的嵌套方法調用是錯誤的。而且我不太瞭解SOAP :: Lite或webservices。建議感激！

my $lookup = SOAP::Lite->service('http://hostname.com/path/SpringVerifierWebServicePort?wsdl') 
    -> proxy("$theURL") ; 
$response = $lookup->verifySpring(''); 

這就是在通話中產生這個存根。

<?xml version="1.0" encoding="UTF-8"?> 
    <soap:Envelope soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="http://webservice.springverifier.toolslang.fedins.com" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soap:Body> 
     <tns:verifySpring> 
     <verifySpring xsi:nil="true" xsi:type="tns:verifySpring" /> 
     </tns:verifySpring> </soap:Body></soap:Envelope> 

SOAP::Transport::HTTP::Client::send_receive: HTTP::Response=HASH(0x167bee8) 
SOAP::Transport::HTTP::Client::send_receive: HTTP/1.1 500 Internal Server Error 

該webservice的提供者告訴我500錯誤是由於調用中的嵌套verifySpring。我是否需要以不同於我的方式調用它，還是WSDL無效並搞砸了SOAP :: Lite？我不太瞭解SOAP和Web服務，以說明問題是否是WSDL，或者是否需要在SOAP :: LITE中以不同的方式調用它。有誰能給我一些方向嗎？

提供商WSDL是這樣的：

'' 是一個實際值（空字符串），使用verifySpring();和不verifySpring(''); 例

#!/usr/bin/perl -- 
use strict; 
use warnings; 
use SOAP::Lite; 
my $soap = SOAP::Lite 
    -> uri('http://127.0.0.1/MyModule') 
    -> proxy('http://127.0.0.1:1203') 
;;;;;;;;; 
$soap->readable(1); 
$soap->transport->add_handler("request_send", sub { print $_[0]->as_string,"\n"; return }); 
eval { $soap->verifySpring(''); 1 } or print "$@\n"; 
eval { $soap->verifySpring(); 1 } or print "$@\n"; 
__END__
