肥皂要求不好，为什么？

Question

这是我的请求xml代码：

<SOAP-ENV:Envelope
   xmlns:SOAP-ENV = "http://www.w3.org/2001/12/soap-envelope"
   SOAP-ENV:encodingStyle = "http://www.w3.org/2001/12/soap-encoding">

   <SOAP-ENV:Body xmlns:m = "http://example.org/quotations">
      <m:GetQuotation>
         <m:QuotationsName>MiscroSoft</m:QuotationsName>
      </m:GetQuotation>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我从w3c school复制了此内容。

当我使用工具（如邮递员之类的回旋镖）将此请求发送到本地服务器时，收到以下错误消息：

我的问题是怎么回事？我不知道发生了什么。

这是我的wsdl文件：

这是我的服务器代码：

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 = {
  MyService: {
      MyPort: {
          MyFunction: function(args) {
              return {
                  name: args.name
              };
          },

          // This is how to define an asynchronous function.
          MyAsyncFunction: function(args, callback) {
              // do some work
              callback({
                  name: args.name
              });
          },

          // This is how to receive incoming headers
          HeadersAwareFunction: function(args, cb, headers) {
              return {
                  name: headers.Token
              };
          },

          // You can also inspect the original `req`
          reallyDetailedFunction: function(args, cb, headers, req) {
              console.log('SOAP `reallyDetailedFunction` request from ' + req.connection.remoteAddress);
              return {
                  name: headers.Token
              };
          }
      }
  }
};

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, '/wsdl', myService, xml);

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