Pass a JSON Array for POST request using Rest Assured based on the following JSON - rest-assured

Question

I am new to Rest Assured, Please can someone help me to create the body request from the following output:
{
"CustomerID": "539177",
"ReminderTitle": "Demo Reminder Tds",
"ReminderDescription": "xyz Reminder",
"ReminderLocation": "New Delhi",
"ReminderDate": "2020-03-27",
"ReminderTime": "15:33",
"attendees": [{
"CustomerContactID": "122"
}]
}
Example :
Map <String, String> body = new HashMap <String, String> ();
body.put("CustomerID", CustomerID);
body.put("ReminderTitle", "Demo Reminder Tds");
body.put("ReminderDescription", "xyz Reminder");
body.put("ReminderLocation", "New Delhi");
body.put("ReminderDate", "2020-03-27");
body.put("ReminderTime", "15:33");

Answer 1

Map<String, Object> map = new LinkedHashMap<>();
map.put("CustomerID", "539177");
map.put("ReminderTitle", "Demo Reminder Tds");
map.put("ReminderDescription", "xyz Reminder");
map.put("ReminderLocation", "New Delhi");
map.put("ReminderDate", "2020-03-27");
map.put("ReminderTime", "15:33");
map.put("attendees", Arrays.asList(new LinkedHashMap<String, Object>() {
{
put("CustomerContactID", "122");
}
}));
Use the below to just print out the output ( you don't have to necessarily )
String abc = new ObjectMapper().writerWithDefaultPrettyPrinter().writeValueAsString(map);
System.out.println(abc);
And to use it with Rest Assured
given().body(map).when().post()

Answer 2

Rest Assured accepts String objects in .body(String body) method. But for POST and PUT methods only. Check the documentation
Therefore you can just pass the output you received.
String requestBody = "{ \"CustomerID\" : \"539177\", " +
"\"ReminderTitle\" : \"Demo Reminder Tds\", " +
"\"ReminderDescription\" : \"xyz Reminder\", " +
"\"ReminderLocation\" : \"New Delhi\", " +
"\"ReminderDate\" : \"2020-03-27\", " +
"\"ReminderTime\" : \"15:33\", " +
"\"attendees\" : [{\"CustomerContactID\" : \"122\"}] }";
BUT you have to use escape characters in the output String.
Then just pass the requestBody;
given()
.body(requestBody)
.when()
.post(URL);
