从 SOAP 响应中的 CDATA 中提取 JSON 内容

Question

我正在处理 SoapUI，我有一个 Soap 请求，它接受 Json 字符串格式的输入，处理后我得到一个 XML 格式的 Soap 响应，JSON 格式包含在 CDATA 中。

我正在尝试使用以下代码从 Soap Response 中提取数据，但出现错误“Prolog 中不允许内容”

import com.eviware.soapui.support.XmlHolder
import net.sf.json.groovy.JsonSlurper
import groovy.xml.Namespace

respXmlHolder = new XmlHolder(messageExchange.getResponseContentAsXml())
respXmlHolder.declareNamespace("ns1","http://tempuri.org/")
CDATAXml = respXmlHolder.getNodeValue("//ns1:ReportResult")
log.info(CDATAXml)


def data = new XmlParser().parseText(CDATAXml).Rpt
log info "data.findAll{it.'Name'}.size()"

Soap 响应如下所示：

<ReportResponse xmlns="http://tempuri.org/">
     <ReportResult><![CDATA[{
  "Report": [
    {
      "Name": "ABC",
      "Number": "123",
      "Type": "XYZ",
      "Desc": "EFGH",
      "Group Name": "Name123",
      "Group Number": "123",
      "End Date": "12/30/2014",
      "Due Date": "04/15/2015",
      "Completion Date": null,
      "Status": "Status1",
      "Received Date": "",
      "Delivery Date": "",
      "Location": "",
      "Role": "",
     },
     {
      "Name": "EFG",
       "Number": "123",
      "Type": "XYZ",
      "Desc": "EFGH",
      "Group Name": "Name123",
      "Group Number": "123",
      "End Date": "12/30/2014",
      "Due Date": "04/15/2015",
      "Completion Date": null,
      "Status": "Status1",
      "Received Date": "",
      "Delivery Date": "",
      "Location": "",
      "Role": "Manager",
     }
    ]
} ]]></ReportResult>
  </ReportResponse>
   </s:Body>
</s:Envelope>

请在这方面帮助我。

正如 cmets 中的 @Rao 注释，您将 //ns1:Result 用作 XPath 但是此节点在您的响应中不存在。无论如何，作为替代而不是使用和XmlHolder，我打算首先使用XmlSlurper 解析SOAP 并获​​取CDATA 节点，然后使用JSonSlurper 解析包含在CDATA 并获得所需的值（在您的情况下，您似乎正在寻找 Name 值属性），请参见以下示例：

import groovy.json.JsonSlurper

def soapResponse = '''<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
   <s:Body>
<ReportResponse xmlns="http://tempuri.org/">
     <ReportResult><![CDATA[{
  "Report": [
    {
      "Name": "ABC",
      "Number": "123",
      "Type": "XYZ",
      "Desc": "EFGH",
      "Group Name": "Name123",
      "Group Number": "123",
      "End Date": "12/30/2014",
      "Due Date": "04/15/2015",
      "Completion Date": null,
      "Status": "Status1",
      "Received Date": "",
      "Delivery Date": "",
      "Location": "",
      "Role": "",
     },
     {
      "Name": "EFG",
       "Number": "123",
      "Type": "XYZ",
      "Desc": "EFGH",
      "Group Name": "Name123",
      "Group Number": "123",
      "End Date": "12/30/2014",
      "Due Date": "04/15/2015",
      "Completion Date": null,
      "Status": "Status1",
      "Received Date": "",
      "Delivery Date": "",
      "Location": "",
      "Role": "Manager",
     }
    ]
} ]]></ReportResult>
  </ReportResponse>
   </s:Body>
</s:Envelope>'''

// parse the soap
def xml = new XmlSlurper().parseText(soapResponse)
// get cdata node
def reportCDATA = xml.'**'.findAll{ it.name() == 'ReportResult' }
def jsonTxt = reportCDATA.pop().toString()
// parse CDATA value as JSON
def json = new JsonSlurper().parseText(jsonTxt)
// get the Name attribute values
def names = json.Report.collect { it.Name }
names.each { log.info it }

如果您在评论时想要获得"Completion Date" 而不是 JSON 的 "Name" 值，您可以这样做：

def completionDates = json.Report.collect { it."Completion Date"}

或者如果看起来更清晰：

def completionDates = json.Report.collect { it[Completion Date] }

请注意，在您的示例中，Report 数组包含两个对象，它们都将null 作为"Completion Date" 的值。因此，使用您的 JSON 示例 def completionDates 将是 [null, null]。

希望对你有帮助，
