我没有收到来自 Google Play 商店的实时开发者通知。我已按照以下步骤操作:
设置消息侦听器。消息接收者代码
public List<ReceivedMessage> recieveAndroidNotification() throws IOException { String subscriptionId = "my-project-id"; String projectId = "my-subscription-id"; SubscriberStubSettings subscriberStubSettings = SubscriberStubSettings.newBuilder().build(); try (SubscriberStub subscriber = GrpcSubscriberStub.create(subscriberStubSettings)) { // String projectId = "my-project-id"; // String subscriptionId = "my-subscription-id"; int numOfMessages = 10; // max number of messages to be pulled String subscriptionName = ProjectSubscriptionName.format(projectId, subscriptionId); PullRequest pullRequest = PullRequest.newBuilder().setMaxMessages(numOfMessages).setReturnImmediately(false) // return immediately if messages are not available .setSubscription(subscriptionName).build(); // use pullCallable().futureCall to asynchronously perform this operation PullResponse pullResponse = subscriber.pullCallable().call(pullRequest); List<String> ackIds = new ArrayList<>(); for (ReceivedMessage message : pullResponse.getReceivedMessagesList()) { // handle received message // ... System.out.println("Message Recived"); ackIds.add(message.getAckId()); } // acknowledge received messages AcknowledgeRequest acknowledgeRequest = AcknowledgeRequest.newBuilder().setSubscription(subscriptionName).addAllAckIds(ackIds) .build(); // use acknowledgeCallable().futureCall to asynchronously perform this operation subscriber.acknowledgeCallable().call(acknowledgeRequest); return pullResponse.getReceivedMessagesList(); } }
向 Cloud Pub/Sub 主题发布测试通知,从而在收到实时通知之前验证该主题的设置和配置。(未收到通知)
手动运行代码然后发送错误:
WARN [2018-06-06 06:37:02,479] com.google.auth.oauth2.ComputeEngineCredentials:无法检测我们是否在 Google Compute Engine 上运行。
我错过了什么吗?
