Question

我试图通过Perl使用SOAP访问Web服务，并且在调用需要参数的服务函数时遇到问题。决定SOAP调用的XSD说，

<xs:complexType name="getVersion"> 
<xs:sequence/> 
</xs:complexType> 
<xs:complexType name="getVersionResponse"> 
<xs:sequence> 
<xs:element minOccurs="0" name="return" type="xs:string"/> 
</xs:sequence> 
</xs:complexType>
...
<xs:complexType name="enumerateEntities"> 
<xs:sequence> 
<xs:element name="entityId" type="xs:int"/> 
<xs:element minOccurs="0" name="entityType" type="tns:entityType"/> 
</xs:sequence> 
</xs:complexType> 
<xs:complexType name="enumerateEntitiesResponse"> 
<xs:sequence> 
<xs:element maxOccurs="unbounded" minOccurs="0" name="return" nillable="true" type="xs:int"/> 
</xs:sequence> 
</xs:complexType>

根据服务的文档，这两个函数的签名是：

String getVersion ()
int[] enumerateEntities (int entityId, EntityType entityType)

我能够使用：

调用第一个函数，该函数不需要输入参数

#!/usr/bin/perl

use SOAP::Lite;
my $uri = 'http://wsdl.mydomain.com/';
my $service = SOAP::Lite
 -> uri($uri)
 -> on_action(sub { sprintf '"Call by on_action: %s"',shift})
 -> proxy('http://192.168.1.100:8688/MyService/services/MyService.MyServicePort/');

$method = SOAP::Data->name("MyService")->attr({xmlns => $uri});
$getVersion = SOAP::Data->name("getVersion")->attr({xmlns=>$uri});#line 11
my $theResult = $service->getVersion;

unless ($theResult->fault){ print "Version: "; print $theResult->result;}
else {print $theResult->faultstring;}

...但是我通过更改第11行来调用带参数的函数的尝试（下面）是徒劳的。

...
@entityId = SOAP::Data->type('int')->name('entityId')->value(0);
@entityType = SOAP::Data->type('EntityType')->name('entityType')->value(NODE);
$enumerateEntities = SOAP::Data->name("enumerateEntities",@entityId,@entityType)->attr({xmlns=>$uri});
my $result2 = $service->enumerateEntities;
print $result2->result;

我做错了什么阻止我用参数调用服务的功能？

修改这是使用SOAP :: WSDL

的更新示例代码

#!/usr/bin/perl

use SOAP::WSDL;
use Data::Dumper;

my $service = SOAP::WSDL->new(
   wsdl => 'http://192.168.1.100:8688/MyService/services/MyService.MyServicePort?wsdl',
   outputhash => 1
);

使用SOAP::WSDL来使用服务wsdl，它也可以为您提供和（可选）到普通perl数据结构的编组。强烈推荐的模块。

如下所示：

use SOAP::WSDL;
use Data::Dumper;

my $soap = SOAP::WSDL->new(
  wsdl => 'http://server/pathtoservice?WSDL',
  outputhash => 1
);
my $res = $soap->call('method', { foo => 1, bar =>2 });
die $res->faultstring if $res->fault;
print Dumper($res->result);

您可以使用wsdl2perl.pl从wsdl生成客户端存根代码。这让事情变得非常简单。 wsdl2perl.pl是SOAP :: WSDL的一部分。以下是生成客户端存根之后的示例代码。

use MyInterfaces::SoapImplService::SoapPort;

my $soap = MyInterfaces::SoapImplService::SoapPort->new();
#calling method createRecipient which takes 2 parameterss:
#1. Complex type : recipient
#2. Complex type : authentication

my $response=$soap->createRecipient( { # MyTypes::createRecipient
    recipient =>  { # MyTypes::Recipient
      address =>  "test701\@test.com", # string
      externalID =>  "test701\@test.com", # string
      sourceDescription =>  "testing perl", # string
      demographics =>  { # MyTypes::StringCollection
        },
    },
  },,
 { # MyTypes::authentication
   username=>'testuser' , password=>'pass'
  },,
 );

#you can find example code of calling every function in your "MyInterfaces\SoapImplService\SoapPort.pm" file.

如果您遇到WSDL问题，可以尝试使用SOAP :: Lite：

记住，你总是可以使用：

use SOAP::Lite qw(trace);

查看您发送的确切XML，以了解您的距离。

我没有时间对此进行测试，但这是我最好的猜测：

my $soap = SOAP::Lite
 -> uri($uri)
 -> on_action(sub { sprintf '"Call by on_action: %s"',shift})
 -> proxy('http://192.168.1.100:8688/MyService/services/MyService.MyServicePort/');

my $id = SOAP::Data->type('int')->name('entityId')->value(0);
my $type= SOAP::Data->type('EntityType')->name('entityType')->value(NODE);
$soap->enumerateEntities($id, $param);

使用带Perl的SOAP调用带参数的函数
