问题描述
好吧，我已经解决了这个问题。真正的问题是，我没能以检索的object
id，在我的情况下invoiceid（in_18qcFkElSMaq70BZy1US7o3g）。此ID是发生事件的ID。表示如果是payment
successful事件，object id则将为charge
id。我不得不转换event对象，map然后获得所需的属性。以下是我为解决该问题所做的完整代码段。
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);
}
解决方法
在Java中实现条纹Webhook时，我成功获取了JSON格式的事件对象。问题是我无法获取嵌套JSON中的详细信息，例如数量，subscription_id，属性。从类对象获取这些值也不可用。你能告诉我如何提取这些值吗
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);
}
我得到以下回应：
Webhook event : <com.stripe.model.Event@1462134034 id=evt_18qdEBElSMaq70BZlEwdDJG3> JSON: {

我想要得到的值一样customer_id，subscription_id等等。但是，当我试图让使用事件对象中的数据，我不能简单地做的event.get....。我将如何提取数据。
