Retrieve lane data from webhook lane event

Question

When implementing stripe webhook in java, I can get the event object in JSON format. The problem is that I cannot get the details, such as quantity, subscription_id, attributes, which are in the nested JSON. Retrieving these values ​​from a class object is also not available. Could you tell me how to extract these values.

public void handle(HttpServletRequest request) {

    Stripe.apiKey = sk_test_XXXXXXXXXXXXXXXXXXXX;

    String rawJson = "";

    try {
            rawJson = IOUtils.toString(request.getInputStream());
        } 
        catch (IOException ex) {
            System.out.println("Error extracting json value : " + ex.getMessage());
         }
    Event event = APIResource.GSON.fromJson(rawJson, Event.class);
    System.out.println("Webhook event : " + event);

}

And I get the following answer: -

Webhook event : <com.stripe.model.Event@1462134034 id=evt_18qdEBElSMaq70BZlEwdDJG3> JSON: {

I want to get values ​​like customer_id, subscription_idetc. But when I try to get data using an event object, I could not just do it like event.get..... How to extract data.

Thank you in advance

Answer 1

, . , object id, invoiceid (in_18qcFkElSMaq70BZy1US7o3g). id . , payment successful, object id charge id. event map, . , .

public void handle(HttpServletRequest request) {   

    Stripe.apiKey = sk_test_XXXXXXXXXXXXXXXXXXXX;

    String rawJson = "";

    try {
         rawJson = IOUtils.toString(request.getInputStream());
    } 
    catch (IOException ex) {
       System.out.println("Error extracting json value : " + ex.getMessage());
    }

    Event event = APIResource.GSON.fromJson(rawJson, Event.class);
    System.out.println("Webhook event : " + event);

    // Converting event object to map
    ObjectMapper m = new ObjectMapper();
    @SuppressWarnings("unchecked")
    Map<String, Object> props = m.convertValue(event.getData(), Map.class);

    // Getting required data
    Object dataMap = props.get("object");

    @SuppressWarnings("unchecked")
    Map<String, String> objectMapper = m.convertValue(dataMap, Map.class);

    String invoiceId = objectMapper.get("id");

    System.out.println("invoideId : " + invoiceId);
}

Answer 2

Stripe webhook. data.object. : charge.* , invoice.* ..

Stripe Java bindings :

StripeObject stripeObject = event.getData().getObject();

stripeObject .

:

if (event.getType().equals("invoice.payment_failed")) {
    Invoice invoice = event.getData().getObject();
