如何将弃用的SoapService调用转换为新的UrlFetchApp [英] How to convert an deprecated SoapService call to the new UrlFetchApp

问题描述

我在这里找到了一个关于如何使用谷歌驱动器脚本调用web服务的示例： https://developers.google .com / apps-script / articles / soap_geoip_example

 函数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）; 
返回result.Envelope.Body.GetGeoIPResponse.GetGeoIPResult.CountryCode.Text; 
} 
  

但是，这会使用不推荐使用的SoapService。该文档说我应该使用 UrlFetchApp
转换输入XML很容易。但是谁能告诉我如何使用UrlFetchApp调用webservice？

经过一天的谷歌搜索和尝试，我得到它与 UrlFetchApp

 函数UrlFetchAppDetermineCountryFromIP_（ipAddress）{
 var xml = 
<？xml version = \\ \\1.0 \编码= \\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（）; 
 $ b返回getGeoIPResponse 
 .getChild（GetGeoIPResult，getGeoIPResponseNamespace）
 .getChild（CountryCode，getGeoIPResponseNamespace）
 .getText（）; 
 
 
 
 $ b 
使用 XmlService ，但是我尝试了几个小时，无法在Evnelope元素上放置4个xmlns属性，导致web服务请求失败
 
I found an example on how to call a webservice with google drive scripts here: 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;
}
However this uses the SoapService wich is deprecated. the documentation says i should use UrlFetchApp
Converting the input xml is easy. But can anyone tell me how to call a webservice with the UrlFetchApp?
解决方案
It turns out to be a lot more work, but after a day of googling and trying i got it to work with the 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();
}
It should probely be posable to build the payload xml with the XmlService, however i tryed that for a few hours and was unable to put the 4 xmlns attributes on the Evnelope element, wich caused the webservice request to fail
