如何將已過時SoapService調用轉換爲新的UrlFetchApp

Question

我發現瞭如何調用web服務與谷歌在此驅動腳本的例子：https://developers.google.com/apps-script/articles/soap_geoip_example

function determineCountryFromIP(ipAddress) { 
    var wsdl = SoapService.wsdl("http://www.webservicex.net/geoipservice.asmx?wsdl"); 
    var geoService = wsdl.getGeoIPService(); 

    var param = Xml.element("GetGeoIP", [ 
       Xml.attribute("xmlns", "http://www.webservicex.net/"), 
       Xml.element("IPAddress", [ 
       ipAddress 
       ]) 
      ]); 

    var result = geoService.GetGeoIP(param); 
    return result.Envelope.Body.GetGeoIPResponse.GetGeoIPResult.CountryCode.Text; 
} 

然而，這使用SoapService至極已經過時了。該文檔說我應該使用UrlFetchApp 轉換輸入xml很容易。但誰能告訴我如何使用UrlFetchApp調用Web服務？

它原來是多了很多的工作，但谷歌搜索，並試圖一整天后，我得到它與UrlFetchApp

function UrlFetchAppDetermineCountryFromIP_(ipAddress) { 
    var xml =   
    "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" 
    +"<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">" 
     +"<SOAP-ENV:Body>" 
     +"<GetGeoIP xmlns=\"http://www.webservicex.net/\">" 
      +"<IPAddress>"+ ipAddress +"</IPAddress>" 
     +"</GetGeoIP>" 
     +"</SOAP-ENV:Body>" 
    +"</SOAP-ENV:Envelope>" 

    var options = 
    { 
    "method" : "post", 
    "contentType" : "text/xml", 
    "payload" : xml 
    }; 

    var result = UrlFetchApp.fetch("http://www.webservicex.net/geoipservice.asmx?wsdl", options); 

    var xmlResult = XmlService.parse(result).getRootElement(); 
    var soapNamespace = xmlResult.getNamespace("soap"); 
    var getGeoIPResponse = xmlResult.getChild("Body", soapNamespace).getChildren()[0]; 
    var getGeoIPResponseNamespace = getGeoIPResponse.getNamespace(); 

    return getGeoIPResponse 
    .getChild("GetGeoIPResult", getGeoIPResponseNamespace) 
    .getChild("CountryCode", getGeoIPResponseNamespace) 
    .getText(); 
} 

工作應該probely是塑形與XmlService建立有效載荷的xml ，但是我嘗試了幾個小時，並且無法在Evnelope元素上放置4個xmlns屬性，導致web服務請求失敗
