Question

我正在尝试使用Amazon SNS控制台中的发布终点从我的应用服务器向Android设备发送推送通知（PN），此消息和消息结构为json，它正常工作。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

    <div class="pc-row sortable">

</div>

但是当我尝试在Java中实现它时，设备不会收到通知。

{
"GCM": "{ \"notification\": { \"text\": \"test message\" } }"
}

控制台上的响应

Publist请求：{TargetArn： ARN：AWS：SNS：AP-南-1：818862955266：端点/ GCM / TestApp / a1ec8114-58c9-371b-bb76-d8d16e674e52，消息： { “默认”： “测试”， “GCM”：{ “通知”：{ “文”： “你好”}}}，MessageStructure： json，MessageAttributes：{}} {MessageId： 7dfb613c-06d0-5fe6-8766-3068c9438614} {AWS_REQUEST_ID = 3d0e13f4-b2be-5c95-ad43-42a07d2d5567}

可能是什么问题？

另外，我遵循SO回答here中建议的模式。

这终于奏效了。我用过jackson解析器。

public class PushRequest {

    @JsonProperty("default")
    private String def;
    @JsonProperty("GCM")
    private GCM gcm;
    public String getDef() {
        return def;
    }
    public void setDef(String def) {
        this.def = def;
    }
    public GCM getGcm() {
        return gcm;
    }
    public void setGcm(GCM gcm) {
        this.gcm = gcm;
    }



}

public class GCM {
    private Notification notification;

    @JsonProperty("notification")
    public Notification getNotification() {
        return notification;
    }

    public void setNotification(Notification notification) {
        this.notification = notification;
    }


}
public class Notification {
    private String text;

    @JsonProperty("text")
    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }

}


PublishRequest publishRequest = new PublishRequest();
            publishRequest.setTargetArn("arn:aws:sns:ap-south-1:818862955266:endpoint/GCM/TestApp/ac338195-1b87-3521-bd98-b7867a83ff27");

//          String message = "{\"GCM\": \"{ \"notification\": { \"text\": \"test message\" } }\"}";

            ObjectMapper mapper = new ObjectMapper();
            PushRequest pushRequest = new PushRequest();
            pushRequest.setDef("Testing out FB messages");

            GCM gcm = new GCM();
            Notification notification = new Notification();
            notification.setText("hello");
            gcm.setNotification(notification);
            pushRequest.setGcm(gcm);

            String jsonInString = mapper.writeValueAsString(pushRequest);
            publishRequest.setMessage(jsonInString);
            publishRequest.setMessageStructure("json");
            System.out.println("Publist request:"+publishRequest.toString());
            PublishResult publishResult = amazonSNSTemplate.getAmazonSNSClient().publish(publishRequest);
            System.out.println(publishResult.toString());
            System.out.println(publishResult.getSdkResponseMetadata().toString());
