Question

我之前从未使用过SOAP，而且我是Perl脚本的新手。

使用perl客户端调用SOAP wsdl服务（Strawberry Perl (64-bit) 5.18.2.2-64bit）以下是为“HelloWorld()”简单方法编写的perl脚本，用于调用

use SOAP::Lite +trace;

- 加载WSDL文档

my $client = SOAP::Lite->service(
      'http://myhost:8080/mySoapDemo/services/simpleSoapApi?wsdl');

- 调用RPC

$result = $client->HelloWorld();

- 显示结果

print "welcome message is: $result\n";

但未收到HelloWorld()方法的欢迎讯息。而不是像<faultcode>和<faultstring>

那样获取xml

以下是有助于问题域的命令行跟踪代码：

<?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/soap/envelope/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="http://soap.corporate.j2.com" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/X

请帮我解决脚本出了什么问题。在此先感谢！..

请找到WSDL：

看起来你的wsdl不正确。

请你试试这些：

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions name="simpleSoapDemo" targetNamespace="http://soap.exampleNameSpace.com" xmlns:tns="http://soap.exampleNameSpace.com" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
  <wsdl:types>

        <xs:schema  xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="unqualified"
            targetNamespace="http://soap.exampleNameSpace.com" version="1.0">
            <xs:element name="HelloWorld" type="tns:HelloWorld" />
            <xs:element name="HelloWorldResponse" type="tns:HelloWorldResponse" />
            <xs:complexType name="HelloWorldResponse">
                <xs:sequence>
                    <xs:element minOccurs="0" name="return" type="xs:string" />
                </xs:sequence>
            </xs:complexType>
        </xs:schema>
        </wsdl:types>
    <wsdl:message name="HelloWorldRequest">
    </wsdl:message>
    <wsdl:message name="HelloWorldResponse">
        <wsdl:part element="tns:HelloWorldResponse" name="parameters">
        </wsdl:part>
    </wsdl:message>
    <wsdl:portType name="SimpleSoapApiServiceWsdlEndpoint">
        <wsdl:operation name="HelloWorld">
            <wsdl:input message="tns:HelloWorldRequest" name="HelloWorld">
            </wsdl:input>
            <wsdl:output message="tns:HelloWorldResponse" name="HelloWorldResponse">
            </wsdl:output>
        </wsdl:operation>
    </wsdl:portType>
    <wsdl:binding name="simpleSoapDemoSoapBinding" type="tns:SimpleSoapApiServiceWsdlEndpoint">

            </wsdl:input>
            <wsdl:output name="HelloWorldResponse">
                <soap:body use="literal" />
            </wsdl:output>
