我试图将Google的Firebase消息平台与我的应用程序联系起来，并尝试使用Spring内置的REST模板REST抽象来简化它

我目前正在尝试：

RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new GsonHttpMessageConverter());

MultiValueMap<String, String> headers = new LinkedMultiValueMap<>();
headers.add("Authorization", "key=" + Constants.FIREBASE_SERVER_KEY);
headers.add("Content-Type", "application/json");

HttpEntity<FireBasePost> entity = new HttpEntity<>(fbp, headers);
URI uri;
uri = new URI(firebaseApi);

FireBaseResponse fbr = restTemplate.postForObject(uri, entity, FireBaseResponse.class);

我很难理解为什么这个电话永远不会结束。我希望能够将响应直接输入到对象中。

尝试如下：

        //---- use this one ----
        public boolean is_success() {
            if (getSuccess() == 1) {
                return true;
            } else {

我认为

FireBaseResponse

属性名称没有遵循正确的惯例。尝试使用驼峰大小写名称（

multicastId

，

canonicalid

，等等：）。你能发布你的Firebase回复吗？你能处理客户端收到的这些通知吗？例如，在

func应用程序（application:UIApplication，DidReceiveMemoteNotification用户信息：[AnyHashable:Any]，fetchCompletionHandler completionHandler:@escaping（UIBackgroundFetchResult）->（））
