使用Perl的Soap :: Lite调用简单的Soap API

标签: perl soap soaplite

我正在尝试使用SOAP :: Lite模块进行简单的API调用(至少这是我刚开始时的想法)。我正在使用一种公共可用的SOAP API here来添加两个数字。我收到以下错误消息:

  

服务器无法识别HTTP标头SOAPAction的值:   http://tempuri.org/#Add

我在SOAP :: Lite中启用了调试,看来我的请求格式不正确。我怀疑intA和intB中指定的类型(xsi:type =“ xsd:int”)引起了问题。

来自调试的请求:

<?xml version="1.0" encoding="UTF-8"?> <soap:Envelope
    soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">   
  <soap:Body>
    <Add xmlns="http://tempuri.org/">
      <intA xsi:type="xsd:int">5</intA>
      <intB xsi:type="xsd:int">10</intB>
    </Add>   
 </soap:Body> </soap:Envelope>

这是我的Perl代码:

#!/usr/bin/env perl

use strict;
use warnings;
use SOAP::Lite;
#use SOAP::Lite +trace => 'all';    

    SOAP::Lite->import(trace => 'debug');

    #my $uri = 'http://tempuri.org/';
    my $proxy = 'http://www.dneonline.com/calculator.asmx';
    my $ns = 'http://tempuri.org/'; 

    my $client = SOAP::Lite
            ->readable(1)
            ->uri($ns)
            ->proxy($proxy);

    my $param1 = SOAP::Data->name("intA" => $x);
    my $param2 = SOAP::Data->name("intB" => $y);

    my $response = $client->Add($param1,$param2);

    print "Result is $response \n";

注意:我尝试在SOAPUI工具中加载WSDL,并且该API在该处工作正常。

更新

按照@simbabque的建议,我尝试使用LWP :: ConsoleLogger调试

标题看起来像这样:

我不知道#的来源。也许我会尝试SOAP :: Simple,看看是否有帮助。

URI和方法名(Add)连接在一起以构建http标头 名为SOAPAction。

URI必须以“ /”结尾。 SOAP :: Lite将它们与“#”合并。

很久以前,我遇到了同样的问题。发现基于.NET的Web服务令人失望,无法看到“#”并通过on_action处理程序(仅将URI和方法名称连接在一起)从手册页中了解了该解决方案。 所有这些都在man SOAP :: Lite

中有详细记录。
my $client = SOAP::Lite->new(
  readable => 1,
  # uri is the same as package/class name into cgi file; must end with "/"
  uri => $ns, 
  # on action corrects SOAPAction to make .NET happy. .NET dislike the '#' 
  # $_[1] will contain method name on $client->call('someMethName')
  on_action => sub { return '"'. $ns . $_[1] .'"'; },  
  # proxy is the full resource URL of aspx/php/cgi/pl wich implements method name 
  proxy => $proxy);
# rest of your code...
