java - APNs 推送通知发送的 Iphone 表情符号 Unicode 解码问题

Question

我的网络服务向 APNs 发布推送通知，APNs 发送到目标 IOS 设备。 当 apns 在警报正文推送通知上包含 Unicode 表情符号并且 Iphone 操作系统无法解码我的 Unicode 表情符号“\uD83D\uDE0A”应用程序已经终止。

推送通知显示相同的“\uD83D\uDE0A”，顶部的横幅通知栏上没有显示表情符号。

Android 应用程序通过 GCM 发送推送通知正常工作，但 IOS 不支持。 Iphone-Ios 只支持这种格式 '\ue415'

这里是从 ActiveMQ 订阅聊天有效负载进入网络服务的代码

            public void onPublish(UTF8Buffer topic, Buffer msg, Runnable ack) {
            try {

                String body = msg.utf8().toString();
                if (logger.isInfoEnabled()) {
                    logger.info("MQTT connection.listener.onPublish(), msg Received ["
                            + body + "]");
                }
                if (body.contains("\"cmd\":\"chat\"")
                        && body.contains("\"is_sender_msg\":true")) { 
                    QueueMgr.addToChatQueue(body); //Changed true to false
                }
                else if(body.contains("\"cmd\":\"msg_seen\"")){
                    QueueMgr.addToChatReadSeenQueue(body);
                }
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                ack.run();
            }
        }

我在 java 上创建推送通知的代码

public static JSONObject constructePushJson(JSONObject jsonObject,String[] cloudkeyWithDevice) throws JSONException {
    if(cloudkeyWithDevice[0] != null){
        JSONObject pnAPIdata = new JSONObject();
            if(cloudkeyWithDevice[1].equals("a") || cloudkeyWithDevice[1].equals("d")){
                pnAPIdata.put(com.anyorg.constants.AppConstants.FLD_CMD, com.anyorg.constants.AppConstants.CMD_ANDROID_PUSH);
            }
            else{
                pnAPIdata.put(com.anyorg.constants.AppConstants.FLD_CMD, com.anyorg.constants.AppConstants.CMD_IOS_PUSH);
            }
            pnAPIdata.put(com.anyorg.constants.AppConstants.FLD_APP_TOKEN, com.anyorg.constants.AppConstants.DEFAULT_APP_TOKEN);
            pnAPIdata.put(com.anyorg.constants.AppConstants.FLD_DEVICE_TOKEN, cloudkeyWithDevice[0]);
            pnAPIdata.put(com.anyorg.constants.AppConstants.FLD_USER_ID, jsonObject.getInt(com.anyorg.constants.AppConstants.FLD_TO_USER_ID));
            pnAPIdata.put(com.anyorg.constants.AppConstants.FLD_DEVICE_ID, 0);
            String alertMsg=StringEscapeUtils.unescapeJava(jsonObject.getString(com.anyorg.constants.AppConstants.FLD_BODY));
            jsonObject.put(com.anyorg.constants.AppConstants.FLD_BODY,alertMsg);
            pnAPIdata.put(com.anyorg.constants.AppConstants.FLD_ALERT_MSG, "AryaConnect: "+alertMsg);//(jsonObject.isNull("body")) ? jsonObject.getString("from_user_name")+": Sent a file" : jsonObject.getString("from_user_name")+": "+jsonObject.getString("body")
            pnAPIdata.put(com.anyorg.constants.AppConstants.FLD_MSG, jsonObject);//jsonObject.getString(com.anyorg.constants.AppConstants.FLD_BODY)
            pnAPIdata.put(com.anyorg.constants.AppConstants.FLD_CALLBACK_URL, callbackUrl);
            pnAPIdata.put(com.anyorg.constants.AppConstants.MAC_ADDRESS_ID, jsonObject.getString("mobile_rec_id"));
            return pnAPIdata;
    }
    else{
        return null;
    }

}

由 Ios 操作系统管理的 Ios 推送通知

我的 Apache Catalina 日志 我是一名 Web 服务云开发人员，最近一天只针对 Ios 应用程序面临这个问题。所以请，如果有人有知识或以前做过。请告诉我一些想法。 我的推送通知链接中的表情符号。 https://mixpanel.com/help/questions/articles/how-do-i-send-custom-parameters-like-emoji-in-my-push-notifications 谢谢

Answer 1

最后，APNs issue resolve in (Ios app) on java web service code by this Unicode encode and decode process. (unescapeJava 和 escapeJava)来自 lib commons-lang-2.6.jar 和类 org.apache.commons.lang.StringEscapeUtils

emojiBytes = alertMsg.getBytes("UTF-8");
text = new String(emojiBytes, "UTF-8");

private static PushNotificationPayload createPayload(JSONObject jsonObject)
        throws JSONException {

    String alertMsg = Common.getStringUnicodeAsNull1(jsonObject,
            AppConstants.FLD_ALERT_MSG);
    byte[] emojiBytes=null;
    String text=null;
    try {
        emojiBytes = alertMsg.getBytes("UTF-8");
        text = new String(emojiBytes, "UTF-8");
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    //String emojiAsString = new String(emojiBytes, Charset.forName("UTF-8"));
    //System.out.println("@@@@@alertMsg: "+text);
    Integer badgeCnt;
    if (jsonObject.has(AppConstants.FLD_BADGE_CNT)){
        badgeCnt = Common.getIntegerAsNull(jsonObject,
                AppConstants.FLD_BADGE_CNT);
    }else{
        badgeCnt = AppConstants.VAL_ZERO;
    }
    PushNotificationPayload payload = createPayload(badgeCnt, text);
    return payload;
}

String alertMsg = Common.getStringUnicodeAsNull1(jsonObject, AppConstants.FLD_ALERT_MSG);

public static String getStringUnicodeAsNull1(JSONObject jsonObject,
        String key) {
    try {
        if(jsonObject.isNull(key))
            return null;
        else
        return StringEscapeUtils.unescapeJava(jsonObject.getString(key));
    } catch (JSONException je) {
        return null;
    }
}

尊敬的先生女士，如果IOS Push Notification上有java APNs emoji Unicode的其他解决方案。

那请给我一些提示。
谢谢
