How to replace Graphql value stored in graphql file and use that in Rest assured

Question

I am working on Graphql API automation, and have been able to automate the flow successfully. The query is being read from .graphql file, and the response is being validated. But the challenge I am facing right now is to provide the data in query at runtime and use that value for POST request in Rest Assured. Following is the sample code:

public void VerifyGraphqlQuery() {

RestAssured.baseURI = "SOME URL";

File file = new File("./resources/Query.graphql"); //The path of .graphql file

String query = GraphqlTemplate.parseGraphql(file, null);

given().log().all().contentType("application/json")

.body(query)

.when().log().all()

.post("SOME URL")

.then().log().all()

.assertThat().statusCode(200);

}

And the .graphql file is:

query getData {
   {
    getData(
input:{
             name: "Harry"
})}}

Now, I want to parameterize the value of name like we can do for the json file using JSONObject. But can't come up with a solution.
