如何通过节点js使用wsdl webservice

Question

我正在使用强soap节点模块，我想调用webservice，我有wsdl文件。

var soap = require('strong-soap').soap;
var WSDL = soap.WSDL;
var path = require('path');
var options = {};
WSDL.open('./wsdls/RateService_v22.wsdl',options,
  function(err, wsdl) {
    // You should be able to get to any information of this WSDL from this object. Traverse
    // the WSDL tree to get  bindings, operations, services, portTypes, messages,
    // parts, and XSD elements/Attributes.

    var service = wsdl.definitions.services['RateService'];
    //console.log(service.Definitions.call());
    //how to Call rateService ??
});

Answer 1

我不确定strong-soap是如何工作的。但是，我有一些使用node-soap的SOAP实现

基本上，node-soap包使用Promises来保持请求的并发性。

var soap = require('soap');
  var url = 'http://www.webservicex.net/whois.asmx?WSDL';
  var args = {name: 'value'};
  soap.createClient(url, function(err, client) {
      client.GetWhoIS(args, function(err, result) {
          console.log(result);
      });
  });

Answer 2

让我们使用下面的sample SOAP service

按主机名/域名(WhoIS)获取域名注册记录

从您的代码判断，您希望使用本地可用的.wsdl文件，因此保存它：

mkdir wsdl && curl 'http://www.webservicex.net/whois.asmx?WSDL' > wsdl/whois.wsdl

现在，让我们使用以下代码来查询它：

'use strict';

var soap = require('strong-soap').soap;
var url = './wsdl/whois.wsdl';

var requestArgs = {
    HostName: 'webservicex.net'
};

var options = {};
soap.createClient(url, options, function(err, client) {
  var method = client['GetWhoIS'];
  method(requestArgs, function(err, result, envelope, soapHeader) {
    //response envelope
    console.log('Response Envelope: \n' + envelope);
    //'result' is the response body
    console.log('Result: \n' + JSON.stringify(result));
  });
});

它将产生一些有意义的结果。您尝试使用的WSDL.open是使用WSDL结构的meant for。

将WSDL加载到树形结构中。遍历WSDL树以获取绑定、服务、端口、操作等。

您不一定需要它来调用服务
