节点肥皂中未触发SOAP服务处理程序

Question

这是我在Node.js中的服务器代码：

var soap = require('soap')
var http = require('http')
let url = 'https://test.developer.intuit.com/QBWC/TroubleshootWebServiceFS/Service.asmx?wsdl'
var express = require('express')
var bodyParser = require('body-parser')
var logger = require('morgan')

var myService = {
  Hello_Service: {
      Hello_Binding: {
          sayHello: function(args) {
            console.log(args)

              return {
                // I expect to see 'greeting Nick' somewhere in the response, but there is nothing
                  greeting: ' greeting Nick... ' //args.name
              };
          }
      }
  }
};

var xml = require('fs').readFileSync('./test_minimum.wsdl', 'utf8')


var app = express();
app.use(logger('dev'));
app.get('//', (req, res) => res.send('Hello world'))
//body parser middleware are supported (optional)
app.use(bodyParser.raw({type: function(){return true;}, limit: '5mb'}));
app.listen(8001, function(){
    //Note: /wsdl route will be handled by soap module
    //and all other routes & middleware will continue to work
    soap.listen(app, {path: '/wsdl', 
      services: myService, xml: xml,
      attributesKey: 'theAttrs',
      valueKey: 'theVal',
      xmlKey: 'theXml'});

    console.log('express is listening port 8001...')
});

这是我的WSDL文件：

<definitions name = "HelloService"
   targetNamespace = "http://www.examples.com/wsdl/HelloService.wsdl"
   xmlns = "http://schemas.xmlsoap.org/wsdl/"
   xmlns:soap = "http://schemas.xmlsoap.org/wsdl/soap/"
   xmlns:tns = "http://www.examples.com/wsdl/HelloService.wsdl"
   xmlns:xsd = "http://www.w3.org/2001/XMLSchema">

   <message name = "SayHelloRequest">
      <part name = "firstName" type = "xsd:string"/>
   </message>

   <message name = "SayHelloResponse">
      <part name = "greeting" type = "xsd:string"/>
   </message>

   <portType name = "Hello_PortType">
      <operation name = "sayHello">
         <input message = "tns:SayHelloRequest"/>
         <output message = "tns:SayHelloResponse"/>
      </operation>
   </portType>

   <binding name = "Hello_Binding" type = "tns:Hello_PortType">
      <soap:binding style = "rpc"
         transport = "http://schemas.xmlsoap.org/soap/http"/>
      <operation name = "sayHello">
         <soap:operation soapAction = "sayHello"/>
         <input>
            <soap:body
               encodingStyle = "http://schemas.xmlsoap.org/soap/encoding/"
               namespace = "urn:examples:helloservice"
               use = "encoded"/>
         </input>

         <output>
            <soap:body
               encodingStyle = "http://schemas.xmlsoap.org/soap/encoding/"
               namespace = "urn:examples:helloservice"
               use = "encoded"/>
         </output>
      </operation>
   </binding>

   <service name = "Hello_Service">
      <documentation>WSDL File for HelloService</documentation>
      <port binding = "tns:Hello_Binding" name = "Hello_Port">
         <soap:address
            location = "http://www.examples.com/SayHello/" />
      </port>
   </service>
</definitions>

它们的服务器正常工作，并将以下请求无错误地发送到http://localhost:8001/wsdl/：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"  xmlns:tns="http://www.examples.com/wsdl/HelloService.wsdl">
    <soap:Body/>
</soap:Envelope>

但是我没有回应“问候尼克”。没有SOAP处理程序被触发。什么地方做错了？
