wsdl soap请求中有多个元素的问题

我在使用wsdl soap请求中的多个元素时遇到问题。当我直接在webservicex网站上尝试以下转换时,我获得当前的货币转换。当我尝试在app脚本中执行相同的操作时,它总是返回“0”的速率。我在这里缺少什么?

function getCurrencyConversion2(){
  var fromCurr = "USD";
  var toCurr = "AUD";
  var wsdl = SoapService.wsdl("http://www.webservicex.net/CurrencyConvertor.asmx?WSDL");
  Logger.log(wsdl.getServiceNames());
  var currencyService = wsdl.getService("CurrencyConvertor");
  Logger.log(currencyService.getOperationNames());
  //var convertOp = currencyService.getOperation("ConversionRate");
  var param = Xml.element("ConversionRate", [
                                  Xml.attribute("xmlns", "http://www.webservicex.net/"),
                                  Xml.element("FromCurrency", [fromCurr]),
                                  Xml.element("ToCurrency", [toCurr])
             ]);
  var result = currencyService.invokeOperation("ConversionRate", [param]);

  return;
}

你会喜欢这个。我也困扰了一段时间。

问题是xmlns的属性区分大小写。当正确的版本为http://www.webservicex.net/时,您将其添加为http://www.webserviceX.NET/。请注意最后的X.NET

以下调整版本应该可以正常工作(以0.9602作为汇率记录XML)。

function getCurrencyConversion2(){
  var fromCurr = "USD";
  var toCurr = "AUD";
  var wsdl = SoapService.wsdl("http://www.webservicex.net/CurrencyConvertor.asmx?WSDL");
  var currencyService = wsdl.getService("CurrencyConvertor");
  var param = Xml.element("ConversionRate", [
                                  Xml.attribute("xmlns", "http://www.webserviceX.NET/"),
                                  Xml.element("FromCurrency", [fromCurr]),
                                  Xml.element("ToCurrency", [toCurr])
             ]);
  var result = currencyService.invokeOperation("ConversionRate", [param]);
  Logger.log(result.toXmlString());
  return;
}

由于SOAP的复杂性以及此服务未返回有价值的错误消息,这很痛苦。
