如何使用Java SDK在AWS SNS中发送app特定的有效载荷？

Question

基于创建远程通知有效负载，可以将应用程序特定的数据发送到 SNS，例如 acme2 在

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

如何使用AmazonSNS在Java中设置数据

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

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

Answer 1

事实证明，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")
