IBM Worklight HTTP-адаптер SOAP-ответ: неудачное преобразование XSL

Question

Я построил HTTP-адаптер, который вызывает мыльную веб-службу ==> он отлично работает. Но когда я добавить файл преобразования XSL и запустить процедуру адаптера с

 transformation : { 
      type : 'xslFile', 
      xslFile : 'filtered.xsl' 
     } 

и пустой XSL файл

<xsl:stylesheet version="1.0" 
      xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
      xmlns:h="http://www.w3.org/1999/xhtml"> 
<xsl:output method="text"/> 

<xsl:template match="/"> 
</xsl:template> 

я получил следующее сообщение об ошибке:

"Ecma Error: TypeError: Cannot read property \"Body\" from undefined 

xml, возвращаемый веб-службой, в порядке (отмечен с помощью WireShark).

Вот код адаптера:

function getLiveSessionsCountFiltered() { 
var request = 
<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:met="http://metricsdata.webservicesimpl.server.introscope.wily.com"> 
    <soapenv:Header/> 
    <soapenv:Body> 
     <met:getLiveMetricData soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> 
     <agentRegex xsi:type="xsd:string">myHost\|websphere\|myAgent</agentRegex> 
     <metricPrefix xsi:type="xsd:string">WebSpherePMI\|servletSessionsModule:LiveCount</metricPrefix> 
     </met:getLiveMetricData> 
    </soapenv:Body> 
</soapenv:Envelope>; 

var input = { 
     method : 'post', 
     returnedContentType : 'xml', 
     path : '/introscope-web-services/services/MetricsDataService', 
     headers: {'SOAPAction':""}, 
     body : { 
      content: request.toString(), 
      contentType: 'text/xml; charset=utf-8' 
     }, 
     transformation : { 
      type : 'xslFile', 
      xslFile : 'filtered.xsl' 
     } 
    }; 

    var result = WL.Server.invokeHttp(input); 
    return result.Envelope.Body; 
} 

И XML вернулся мой SOAP WebService:

Answer 1

адаптер делает именно то, что вы говорите это сделать. В XSL преобразования, вы опуская ответ от сервера (не возвращая ничего), а затем вы ждете результата Envelope.Body присутствовать после преобразования

return result.Envelope.Body; 

Конверт неопределенные на выходе из вашего XSL , поэтому сообщение об ошибке:

"Ecma Error: TypeError: Cannot read property \"Body\" from undefined 

имеет прекрасный смысл. Вам нужно положить что-то на преобразование, чтобы создать конверт и тело:

<xsl:template match="/"> 
    {"Envelope": {"Body": {"content": "This is the content"}}} 
</xsl:template> 

Или вы можете просто оставить конверт/Body из вашего XSL и просто вернуть JSON содержания.

Но если вы развернете тело в XSL, вы не сможете сделать это снова в операторе возврата своей функции.
