SOAP::Lite的Lite是說其好用，其實它的實現并不“輕量”，功能也非常強大，所以我們要用好它。
在調用服務時，有時遇到有復雜結構或者數組時，還是有點小麻煩，下面以調用以下三個函數為例分別寫出SOAP::Lite如何組合它們的參數，其它情況也應該能迎刃而解。
public class DeviceValue 
{
private String devName;
private String devIp;
public String getDevIp() {
return devIp;
}
public void setDevIp(String devIp) {
this.devIp = devIp;
}
public String getDevName() {
return devName;
}
public void setDevName(String devName) {
this.devName = devName;
}
}public interface NotifyService {
public int sendAlarm (DeviceValue alarm);
public String sendAlarmString (String stralarm);
public List<DeviceValue> sendAlarmArr (List<DeviceValue> arr);
}
SOAP::Lite調用及處理返回參數的代碼如下，對照相應函數及PERL中的處理來看：
use SOAP::Lite ( +trace => all, maptype => {} );
my $soap = SOAP::Lite
-> uri('http://magic.nms.exchangebit.com/')
-> on_action( sub{ join '/', 'http://www.alfredbr.com', $_[1] })
-> proxy('http://127.0.0.1:8080/ebnms/NotifyService');
my $header = SOAP::Header->name(MyHeader => {
MyName => "Alfred"
})->uri('http://www.alfredbr.com/')->prefix('');
{# call send alarm
my @params = (
# $header,
SOAP::Data->name(x1 => goodhehe)
);
my $method = SOAP::Data->name('sendAlarmString');
# ->attr({xmlns => 'http://www.alfredbr.com/'});
my $result = $soap->call($method => @params);
print "\nsend string alarm result:\n";
if ($result->fault)
{
print $result->faultstring;
}
else
{
print $result->result;
}
print "\nn";
}
{# call send dev alarm
my @params = (
SOAP::Data->name(x1 => {devName=>"hehe", devIp=>"ip1"})
);
my $method = SOAP::Data->name('sendAlarm');
my $result = $soap->call($method => @params);
print "\nsend string alarm result:\n";
if ($result->fault)
{
print $result->faultstring;
}
else
{
print $result->result;
}
print "\n\n";
}
{# call send arr alarm
my @params = (
SOAP::Data->name(x1 => [
{devName=>"hehe1", devIp=>"ip1"},
{devName=>"hehe2", devIp=>"ip2"}])
);
my $method = SOAP::Data->name('sendAlarmArr');
my $result = $soap->call($method => @params);
print "\nsend string alarm result:\n";
if ($result->fault)
{
print $result->faultstring;
}
else
{
my @a = @{$result->result->{item}};
foreach $i (@a) {
print "ele: $i->{devName}, $i->{devIp}\n";
}
}
print "\n\n";
}
其中，尤其PERL會將HASHMAP“翻譯”成結構，其中的KEY和VALUE就是結構的成員及值；另外，處理參數為結構數組及返回值也是數組的情況。組裝時要用“[]”括起來，返回值要轉換成數組指針再處理，下面是打印出來的請求、回應及函數輸出：

How to Call a .NET-based Web Service Using the SOAP::Lite Perl Library
補充于2007.10.15：
另一法：
A little more difficult now, how to parse arrays returned by web service with SOAP::Lite. We will have to use a technique similar to XPath to read the value returned in the SOAP message. The remote procedure consumed here are collInt() (returning an array of int) and collPos() (returning an array of PosCol object). The PosCol class contain just two simple int variable XPos and YPos. Let's see how to handle these cases:
# Again, no param here so we make the call
my $resultci = $client->collInt();
my $resultcp = $client->collPos();
print "<p><b>Method collInt():</b> return an array of int<br>";
# To understand this code we have to know the structure of
# the SOAP message (the response) returned by the web service
# If you take a look at the wsdl, you will find for the operation
# collInt the complex type collIntResponse, composed with an array
# of result (int) element.
# Another way is to build a classic client with your preferred language
# and catch the SOAP message returned by the web service, see
# TcpTunnelGui tool. So you know
# exactly the structure of the values.
my @intarr = $resultci->valueof('//collIntResponse/result');
# A simple foreach read the array
foreach my $intval (@intarr) {
print "elem: $intval<br>";
}
# Use the same method to parse the array of PosCol object
print "<p><b>Method collPos():</b> return an array of object <u>PosCol</u><table>";
my @poscolarr = $resultcp->valueof('//collPosResponse/result');
foreach my $pcval (@poscolarr) {
print "<tr><td>object -> </td>";
# Here, for each object you can list the key/value elements
# using usual Perl code
foreach my $keyval (keys %{$pcval}) {
print "<td>$keyval: </td><td>" . $pcval->{$keyval} . " </td>";
}
print "</tr>";
}
print "</table>";
