Accessing specific JSON values in a deluge script - json

Question

I have a JSON API response that contains multiple entries, with different types of subscriptions and multiple users.
I need to search the list for a "user_name" AND a "subscription", then return any matching "duration". In some cases, there will be more than one "duration" for a user and subscription. I would need the total (sum) of the duration when there is more than one.
For example, here is a part of an example Json I am working with:
[
{
"id": 139387026,
"user_name": "John Smith",
"note": "",
"last_modify": "2022-03-28 14:16:35",
"date": "2022-03-28",
"locked": "0",
"addons_external_id": "",
"description": "",
"info": [
{
"subscription": "basic",
"duration": "22016",
}
]
},
{
"id": 139387027,
"user_name": "John Smith",
"note": "",
"last_modify": "2022-03-28 14:16:35",
"date": "2022-03-28",
"locked": "0",
"addons_external_id": "",
"description": "",
"info": [
{
"subscription": "advanced",
"duration": "10537",
}
]
},
{
"id": 139387028,
"user_name": "Martin Lock",
"note": "",
"last_modify": "2022-03-28 14:16:35",
"date": "2022-03-28",
"locked": "0",
"addons_external_id": "",
"description": "",
"info": [
{
"subscription": "basic",
"duration": "908",
}
]
},
]
So for example, for user_name: "John Smith" and subscription: "advanced", I need to return duration: "10537".
I've used toJsonlist(); to convert it, then used the code below, but it returns all values in the list. I can't figure out how to search for the specific values or add matching entries together.
rows = subscriptions.toJsonlist();
for each row in rows
{
info row;
user_name = row.getJson("user_name");
info "username: " + user_name;
subscription = row.getJson("subscription");
info "subscription: " + subscription;
subscriptionId = row.getJson("subscriptionId");
info "subscription Id: " + subscriptionId;
}
I'm fairly new to programming. Any help is appreciated!

According to your needs , you want to filter your JSON data and get the corresponding value from your filter in user_name and subcription.
Here is the Deluge Script for that. I use clear variable name so that it will not confused you.
//Your Entry Change this based on your filter
input_user_name = "John Smith";
input_subscription = "advanced";
//Your JSON data
json_string_data = '[ { "id": 139387026, "user_name": "John Smith", "note": "", "last_modify": "2022-03-28 14:16:35", "date": "2022-03-28", "locked": "0", "addons_external_id": "", "description": "", "info": [ { "subscription": "basic", "duration": "22016", } ] }, { "id": 139387027, "user_name": "John Smith", "note": "", "last_modify": "2022-03-28 14:16:35", "date": "2022-03-28", "locked": "0", "addons_external_id": "", "description": "", "info": [ { "subscription": "advanced", "duration": "10537", } ] }, { "id": 139387028, "user_name": "Martin Lock", "note": "", "last_modify": "2022-03-28 14:16:35", "date": "2022-03-28", "locked": "0", "addons_external_id": "", "description": "", "info": [ { "subscription": "basic", "duration": "908", } ] } ]';
//Declare the data as JSON
processed_json_data = json_string_data.toJsonlist();
initial_total_duration = 0;//Donot change this
list_of_duration = List();
total_duration_per_username_per_subscription = Map();
for each row in processed_json_data
{
if (row.get("user_name") == input_user_name )
{
info_list = row.get("info").toJSONList();
for each info_row in info_list
{
if (info_row.get("subscription") == input_subscription)
{
info_row_duration = info_row.get("duration").toLong(); // make it integer
list_of_duration.add(info_row_duration);
}
}
}
}
result_map = Map();
//Sum of list_of_duration
for each duration in list_of_duration
{
initial_total_duration = initial_total_duration + duration;
}
result_map.put("user_name",input_user_name);
result_map.put("subscription",input_subscription);
result_map.put("no_of_subscription",list_of_duration.size());
result_map.put("total_duration",initial_total_duration);
info result_map;
And the result should be
{"user_name":"John Smith","subscription":"advanced","no_of_subscription":1,"total_duration":10537}
