我有一个使用服务方法获取 wsdl 的 SOAP::Lite 客户端。这需要调用一个没有参数的单一操作和方法的 web 服务。这导致提供者告诉我的嵌套方法调用是错误的。而且我对 SOAP::Lite 或 Web 服务不是很了解。建议赞赏！

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

这就是在通话中生成这个存根。

<?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

该网络服务的提供者告诉我 500 错误是由于调用中嵌套的 verifySpring 造成的。我是否需要以不同的方式调用它，或者 WSDL 是否无效并且搞砸了 SOAP::Lite？我对 SOAP 和 web 服务了解得不够多，无法说明问题是否出在 WSDL，或者我是否需要在 SOAP::LITE 中以不同的方式调用它。任何人都可以给我一些方向吗？

提供者 WSDL 是这样的：

'' 是一个实际值（空字符串），使用verifySpring();而不是verifySpring(''); 示例

#!/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__
