提取json的Groovy类返回null

Question

我正在向库中添加可重用功能。我添加了一个类来从SOAP响应中提取JSON，但我得到一个NULL作为回报。下面的脚本运行正常，问题是我将它添加到类中。

import com.eviware.soapui.support.types.StringToStringMap
import groovy.json.JsonSlurper
import groovy.json.*
responseContent = testRunner.testCase.getTestStepByName("TestStepName").getPropertyValue("response");
slurperresponse = new JsonSlurper().parseText(responseContent);
log.info (slurperresponse.items[0].id);
//Write response to property
def addResponseID = slurperresponse.items[0].id
testRunner.testCase.testSuite.setPropertyValue("ScheduleId", addResponseID)

班级：

import com.eviware.soapui.support.types.StringToStringMap;
import groovy.json.JsonSlurper;
import groovy.json.*;
class GetXmlNode
{
def log
def context
def testRunner
def responseSOAXmlStep
def resultValue
def responseNodePath
def responseContent = "mycontent"
def slurperresponse = "myresponse"
def storeProperty = "id"
// Class constructor with same case as Class name
def GetXmlNode(logIn,contextIn,testRunnerIn)
    {
    this.log = logIn
    this.context = contextIn
    this.responseSOAXmlStep = responseSOAXmlStep
    this.responseNodePath = responseNodePath
    this.testRunner = testRunnerIn
    this.storeProperty = storeProperty
    }

    def execute(responseSOAXmlStep,responseNodePath,storeProperty)
{
    responseContent = testRunner.testCase.getTestStepByName(responseSOAXmlStep).getPropertyValue("response");
        slurperresponse = new JsonSlurper().parseText(responseContent);
    resultValue = (slurperresponse.responseNodePath);
    log.info("Node value: " +  resultValue );
    testRunner.testCase.testSuite.project.setPropertyValue(storeProperty, resultValue );

        return responseSOAXmlStep
}

}
 context.setProperty( "GetXmlNode", new GetXmlNode( log, context, testRunner) )

致电脚本：

// get a reference to the library TestSuite
library = testRunner.getTestCase().getTestSuite().getProject().getWorkspace().getProjectByName("Library")
library = library.getTestSuiteByName("Library");

// find the module within the library 
module = library.testCases["Library"].testSteps["GetXMLNodeValueByJSON"]

// initialise the library; which places an instance of Example in the context
module.run(testRunner, context)

// get the instance of example from the context.
def GetXmlNode = context.GetXmlNode

// run the method, with parameter
 log.info "GetXmlNode.execute(responseSOAXmlStep,responseNodePath,storeProperty) = " +  GetXmlNode.execute("TestStepName","items[0].id","JsonId")

更新代码：

import com.eviware.soapui.support.types.StringToStringMap;
import groovy.json.JsonSlurper;
import groovy.json.*;
class GetXmlNode
{
def log
def context
def testRunner
def responseSOAXmlStep
def resultValue
def responseNodePath = "items[0].id"
def responseContent = ""
def slurperresponse = ""
def storeProperty = ""
// Class constructor with same case as Class name
def GetXmlNode(logIn,contextIn,testRunnerIn)
    {
    this.log = logIn
    this.context = contextIn
    this.responseSOAXmlStep = responseSOAXmlStep
    this.responseNodePath = responseNodePath
    this.testRunner = testRunnerIn
    this.storeProperty = storeProperty
    }

    def execute(responseSOAXmlStep,responseNodePath,storeProperty)
{
    def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context );
    responseContent =     testRunner.testCase.getTestStepByName(responseSOAXmlStep).getProperty("Response").getValue();
        def jsonSlurper = new JsonSlurper().parseText(responseContent);
//          log.info (slurperresponse.responseNodePath);
//      def holder = groovyUtils.getXmlHolder( responseSOAXmlStep+"#ResponseAsXml" );
    resultValue = "resultValue " + jsonSlurper[responseNodePath];
    log.info("Node value: " +  resultValue );
    log.info("Response Node Path: " +responseNodePath)
    testRunner.testCase.testSuite.project.setPropertyValue(storeProperty, resultValue );


        return responseSOAXmlStep
}

}
context.setProperty( "GetXmlNode", new GetXmlNode( log, context, testRunner) )
