SOAP :: Lite发送错误的Envelope命名空间？

Question

我试图向SOAP服务发送消息并收到错误：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><soap:Fault><faultcode>soap:VersionMismatch</faultcode><faultstring>"http://schemas.xmlsoap.org/wsdl/soap/", the namespace on the "Envelope" element, is not a valid SOAP version.</faultstring></soap:Fault></soap:Body></soap:Envelope>

我的代码：

use 5.014;
use warnings 'FATAL' => 'all';

use SOAP::Lite +trace => 'all';

my %data = (
    ...
);

my $service = SOAP::Lite->service('file:wsdl.txt'); 
$service->...(
    SOAP::Data->name('userId')->value('...'),
    SOAP::Data->name('password')->value('...'),
    map( SOAP::Data->name($_)->value($data{$_})->type('string'), sort keys %data )
);

SOAP :: Lite版本是1.09。
