无法阅读属性＆＃39; setSecurity＆＃39; undefined - Node JS，Strong-Soap

Question

我尝试在＆＃34; IIS 8＆＃34;中部署我的节点应用程序。我安装了iisnode。

基本应用程序运行正常。

但是我选择SOAP，我遇到了错误。

Application has thrown an uncaught exception and is terminated:
TypeError: Cannot read property 'setSecurity' of undefined
    at C:\inetpub\iisnode\www\salesorder\so.js:32:11
    at C:\inetpub\iisnode\www\salesorder\node_modules\strong-soap\src\soap.js:48:5
    at C:\inetpub\iisnode\www\salesorder\node_modules\strong-soap\src\soap.js:30:16
    at ReadFileContext.callback (C:\inetpub\iisnode\www\salesorder\node_modules\strong-soap\src\parser\wsdl.js:370:11)
    at FSReqWrap.readFileAfterOpen [as oncomplete] (fs.js:336:13)

代码：

var express = require('express');
var app = express();

app.get('/node/salesorder/myapp/salesorderquery', function(req, res){
    var json = req.query;
  var soap = require('strong-soap').soap;
  var url = '../wsdl/SalesOrderQuery.wsdl';
  var requestArgs = {
    SalesOrderByElementsQuery_sync : {
      ProcessingConditions : {
        QueryHitsMaximumNumberValue : 2 , //json.QueryHitsMaximumNumberValue,
        QueryHitsUnlimitedIndicator : false,
        LastReturnedObjectID : "0000000000011ED18B8B8EA6C678AAE6"
      }
    }
  };
  var options = {
    attributesKey: '$attributes'
  };

  soap.createClient(url, options, function(err, client) {
    client.setSecurity(new soap.BasicAuthSecurity("**APP","******"));
     client.FindByElements(requestArgs, function(err, result, envelope) {
      res.send(JSON.stringify(result));
    });
  });
})

app.listen(process.env.PORT);

请帮我解决这个问题。
