Groovy的鑄造XML NodeChildren爲byte []

我試圖用如下Groovy的鑄造XML NodeChildren爲byte []

<?xml version="1.0" encoding="utf-8"?> 
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> 
    <soap:Body> 
    <SignResult xmlns="http://www.tw.com/tsswitch"> 
     <Result> 
     <Code>string</Code> 
     <Desc>string</Desc> 
     </Result> 
     <SignedDocument>base64Binary</SignedDocument> 
     <Archive>base64Binary</Archive> 
     <Details>string</Details> 
    </SignResult> 
    </soap:Body> 
</soap:Envelope>

下面來解析來自SOAP Web服務的XML響應我的Groovy代碼到XML響應轉換成所需的變量

def responseXML = EntityUtils.toString(httpResponse.getEntity()); 

def signResponse = new XmlSlurper().parseText(responseXML) 
def signedDocument = new XmlSlurper().parseText(responseXML).Body.SignResult.SignedDocument 
def resultCode = new XmlSlurper().parseText(responseXML).Body.SignResult.Result.Code 
def resultDesc = new XmlSlurper().parseText(responseXML).Body.SignResult.Result.Desc 
def archive = new XmlSlurper().parseText(responseXML).Body.SignResult.Archive 
def details = new XmlSlurper().parseText(responseXML).Body.SignResult.Details

我想給signedDocument轉換爲byte[]如下

def document = signedDocument as byte[]

但我得到以下異常

org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object with class 'groovy.util.slurpersupport.NodeChildren' to class 'byte'

有人可以幫助這個mw嗎？

你想幹什麼？該字符串表示該XML的字節[]？ –

@tim_yates是的，然後將其轉換爲文本文件 – RanPaul

所以到節點轉換回字符串，然後得到的字符串的字節數，你可以這樣做：

import groovy.xml.* 

// Ignore namespaces, as otherwise we'll get tag0 namespaces added when we serialise 
def signedDocument = new XmlSlurper(false, false).parseText(responseXML).'soap:Body'.SignResult.SignedDocument 

// Convert to a string, then get the bytes in UTF-8 
byte[] signedDocumentBytes = new StreamingMarkupBuilder() 
    .bindNode(signedDocument) 
    .toString() 
    .getBytes('UTF-8')

當我做'println'簽署的字符串=「+新字符串（signedDocumentBytes，'UTF-8'）'看到' TUlNRS1WZXJzaW9uOiAxLjANCkRhdGU6IE1v'怎麼做我擺脫了''節點，並獲取節點內的文本？ – RanPaul

Errr'signedDocument.text（）' –
