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

基于Creating the Remote Notification Payload，可以将App特定数据发送到SNS，例如，

{
    "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();

最佳答案

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")
