Iphone APNs 推送通知调度的表情符号 Unicode 解码问题

Question

我的网络服务向 APNs 发布推送通知并将 APNs 发送到目标 IOS 设备。当 apns 在警报正文推送通知中包含 Unicode 表情符号并且 Iphone os 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是 IOS 不支持。 Iphone-Ios只支持这种格式'\ue415'

这里是从 ActiveMQ 订阅聊天负载进入 web 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;
    }

}

发布到 APNs 代码

管理的推送通知

我的 Apache Catalina 日志我是一名 Web 服务云开发人员，前几天仅针对 Ios 应用程序面临此问题。所以请，如果有人有知识或以前做过。请告诉我一些想法。我的推送通知中的表情符号 link。 https://mixpanel.com/help/questions/articles/how-do-i-send-custom-parameters-like-emoji-in-my-push-notifications 谢谢

Answer 1

你不需要搞乱 html 解码。正如您所说，笑脸的代码点是 \u263A。在 PHP 中，您可以在 UTF8 编码的字符串中将其表示为“\xE2\x98\xBA”

闪电（实际上'high voltage sign'）是UTF-8中的\u26A1或“\xE2\x9A\xA1”。

这两个字符都作为常规 Unicode 符号出现在某些非表情符号字体中。你可以看到：

<?php
header('Content-type: text/html; charset=utf-8');
echo "\xE2\x9A\xA1";
echo "\xE2\x98\xBA";

或其他事情...

对于 google 员工。 json_encode() 添加双 \

$message = "\ue04a";
$body['aps'] = array(
                   'alert' => $message,
                   'sound' => 'default',
                   'type'  => $type,
                   'param' => $param
               );

$payload = json_encode($body);
$payload = str_replace("\", "\", $payload);

请用这两种方式检查...我认为这对您有帮助。

最后，通过此 Unicode 编码和解码过程，APNs 问题在 java Web 服务代码上的（Ios 应用程序）中得以解决。 (unescapeJava 和 escapeJava) 来自 lib commons-lang-2.6.jar 和 class 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;
    }
}

尊敬的先生和女士，如果 IOS 推送通知上的 java APNs 表情符号 Unicode 有任何其他解决方案。

那请给我一些提示。
