Replace one part in a request with the value from an variable

[amirse]

Hi,

Is there a way to replace the "XXXX" in the method below with the value of the variable replaceToken?

def replaceToken = "username"

parsedJson.secrets.XXXX.toString()

I.e., I would like to achieve following automatically 

parsedJson.secrets.username.toString()

Seems like an easy thing when working with strings but when I want to have it in a call then it always interprets the replaceToken as "replaceToken" and not "username"

Hi,

Have a look at http://blog.gtiwari333.com/2012/08/groovy-grails-dynamic-method-n-variable.html

You can call methods using variables and array elements.

I've created a small Groovy script as a demo.  See below.

def myObj = new MyClass();

// Call in the usual way.
log.info("Call in the usual way.");
log.info(myObj.methodOne());
log.info(myObj.methodTwo());
log.info(myObj.methodThree());
log.info("-------------------------------------------");

// Call using a variable.
log.info("Call using a variable");

def methodToCall = "methodOne";
log.info(myObj."$methodToCall"());

methodToCall = "methodTwo";
log.info(myObj."$methodToCall"());

methodToCall = "methodThree";
log.info(myObj."$methodToCall"());

log.info("-------------------------------------------");

log.info("Call with method name in an array");
def myArray = ["methodOne", "methodTwo", "methodThree"];
log.info(myObj.(myArray[0])());
log.info(myObj.(myArray[1])());
log.info(myObj.(myArray[2])());

log.info("-------------------------------------------");

class MyClass {

	MyClass(){
		// empty constructor
	}

	def methodOne(){
		return "I am method one";
	}

	def methodTwo(){
		return "I am method two";
	}

	def methodThree(){
		return "I am method three";
	}
}

Chris, 

You are a true hero.. Thank you so much. It worked perfectly. Now I am able to read a .json file and set my project properties to the values from the secrets file. Without this I would have to declare every property manually which is not efficient at all. Great!!

//get secret file for the active environment
					secretsJsonFile = projectpath + "ReadyApi_Secrets\\secrets_" + activeEnv + ".json"		//get secrets file for the active environment
					log.info("secretsJsonFile = " + secretsJsonFile)
				
					// Read jsonfile and return text content
					def secretsFile = new File(secretsJsonFile);
					def parsedJson = new JsonSlurper().parseText(secretsFile.text)
					def oneItem, oneItemValue
					
					for(i = 0; i < numberOfProjectProperties; i++)
					{
						oneItem =  projectPropertiesList[i]	//get one item in the projectPropertiesList
						oneItemValue = parsedJson.secrets."$oneItem".toString()	//get the value of the item from the secrets file
						log.info("oneItem = " + oneItem)
						log.info("oneItemValue = " + oneItemValue)

						//set global property value with value from secrets file
						testRunner.testCase.testSuite.project.setPropertyValue( projectPropertiesList[i], oneItemValue)
