如何从Java中的Stripe接收Webhook

Question

我正在尝试通过Stripe Payments的帖子请求接收webhook.处理它的java方法如下所示:

@ResponseBody
@RequestMapping(    consumes="application/json",
                    produces="application/json",
                    method=RequestMethod.POST,
                    value="stripeWebhookEndpoint")
public String stripeWebhookEndpoint(Event event){

    logger.info("\n\n" + event.toString());

    logger.info("\n\n" + event.getId());

    return null;
}

但Stripe事件总是返回所有空值:

<com.stripe.model.Event@315899720 id=null> JSON: {
  "id": null,
  "type": null,
  "user_id": null,
  "livemode": null,
  "created": null,
  "data": null,
  "pending_webhooks": null
}

如果方法接收到String,并使用@RequestBody:

@ResponseBody
@RequestMapping(    consumes="application/json",
                    produces="application/json",
                    method=RequestMethod.POST,
                    value="stripeWebhookEndpoint")
public String stripeWebhookEndpoint(@RequestBody String json){

    logger.info(json);

    return null;
}

在这里,它打印没有空值的json.这是打印请求的一部分:

{
  "created": 1326853478,
  "livemode": false,
  "id": "evt_00000000000000",
  "type": "charge.succeeded",
  "object": "event",
  "request": null,
  "data": {
    "object": {
      "id": "ch_00000000000000",
      "object": "charge",
      "created": 1389985862,
      "livemode": false,
      "paid": true,
      "amount": 2995,
      "currency": "usd",
...
}

但是使用带有Stripe Event参数的@RequestBody 会产生400:错误的语法.

那么为什么我不能接受正确的类型,条纹事件,作为参数？

Answer 1

public String stripeWebhookEndpoint(@RequestBody String json, HttpServletRequest request) {         
        String header = request.getHeader("Stripe-Signature");      
        String endpointSecret = "your stripe webhook secret";
        try {
            event = Webhook.constructEvent(json, header, endpointSecret);
            System.err.println(event);
        } catch (SignatureVerificationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
         //
         enter code here
      return "";

}

这是我做的:

Java方法仍然将事件作为json String接收.然后我使用了Stripe的自定义gson适配器并获得了以下事件:

Event event = Event.gson.fromJson(stripeJsonEvent, Event.class);

其中stripeJsonEvent是webhook端点接收的json字符串.

我一直在寻找相同的答案,所以在看了他们自己的代码后,他们实际上是这样做的:

String rawJson = IOUtils.toString(request.getInputStream());
Event event = APIResource.GSON.fromJson(rawJson, Event.class);

APIResource来自他们的图书馆(我使用的是1.6.5)
