JsonPath js_prescrition = newJsonPath(response_prescription);
Object prescription = js_prescrition.get("prescription");
JsonPath js_prescrition1 = new JsonPath("prescription");
String medicine = js_prescrition.get("Medicine");
System.out.println(medicine);

CodePudding user response：

This code would help you

String data = given()...asString();
String prescription = JsonPath.from(data).getString("[0].prescription").replaceAll("\\\\", "");
List<Map<String, ?>> nested = JsonPath.from(prescription).get("prescription");
String medicine = (String) nested.get(0).get("Medicine");
System.out.println(medicine);
//Hair Ras
