java - 如何使用 Java SDK 在 AWS SNS 中发送应用程序特定的负载？

Question

基于Creating the Remote Notification Payload可以将应用程序特定数据发送到 SNS，例如 acme2 中的

{
    "aps" : { "alert" : "Message received from Bob" },
    "acme2" : [ "bang",  "whiz" ]
}

如何使用 AmazonSNS 在 Java 中设置该数据

final PublishRequest publishRequest = new PublishRequest();
publishRequest
    .withTargetArn(getDeviceEndpoint())
    .withMessage(notification.getMessage())
    .withSubject(notification.getTitle());

return snsClient.publish(publishRequest).getMessageId();

Answer 1

原来我需要将消息类型设置为 json

 publishRequest
                .withTargetArn(userByUsername.get().getDeviceEndpoint())
                .withMessage("{... json here ... }")
                .withSubject(enclosedNotificiation.getTitle())
                .withMessageStructure("json")
