node.js 调用天气webservice接口

首先安装soap模块

npm install soap

  var soap = require('soap');
  var url = 'http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl';
  var args = {	byProvinceName: '江苏'};
  exports.soaptest = function(){soap.createClient(url, function(err, client) {
		  client.setSOAPAction("http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity");
		  client.getSupportCity(args, function(err, result) {
			  console.log(result);
		  });
	  });
  }

在模块lib中找到client.js

修改：

soapAction = this.SOAPAction ? this.SOAPAction(ns, name) : (method.soapAction || (((ns.lastIndexOf("/") != ns.length - 1) ? ns + "/" : ns) + name)),

为：

soapAction = method.soapAction || (((ns.lastIndexOf("/") != ns.length - 1) ? ns + "/" : ns) + name),

调用返回数据：
