GCM在登录后未将推送通知发送给离线用户……不知道我缺少了什么吗？

Question

当用户离线并上线时，我尝试从其接收推送通知的电话未收到它，regId和结果返回，因此不确定是什么在阻止它，也未收到错误...

编辑：我有一个用户脱机，然后他将联机，并且仅当用户在推送时处于联机状态时，消息才会被推送给他...

这是服务器端的代码：

// //BELOW FOR GCM
function notifyDetails(to, from, msg, itemId,  itemName, fromName, type) {

User.findOne({_id: to}, function(err, results) {
        if(err) {
            throw err; 
        } else {
                callNotify();
            function callNotify() {
                console.log("the from is " + results.reg_id);
                if(results != null) {
                    request(
                { method: 'POST',
                uri: 'https://android.googleapis.com/gcm/send',
                headers: {
                    'Content-Type': 'application/json',
                    'Authorization': GOOGLE API KEY
                },

                    "registration_ids": [results.reg_id],
                    "data": {
                        "notifyFromUserId": from,
                        "notifyMsg": msg,
                        "notifyItemId": itemId,
                        "notifyItemName": itemName,
                        "notifyFromName": fromName,
                        "notifyType": type


                    },
                 //default 4 weeks (this is in seconds)
                    //"time_to_live": 20000
                })
            }, function (error, response, body) {
                if(error) {
                    throw error;
                } else {

                    }

                });
                }

        }
            }


    });



}

1. 尝试发送推送消息时，您从GCM服务器收到什么响应？ 请在此处发布回复。 您也可以通过我的测试推送服务器帮助来诊断问题所在。

2. 在MSGReceveier.onReceve中，重新包装意图时您不需要做任何工作。 只需为现有意图设置组件并将其传递给您的服务即可：

    onReceive(Context context, Intent intent) { intent.setComponent(new ComponentName(context.getPackageName(), MSGService.class.getName()); startWakefulService(context,msgrcv); setResultCode(Activity.RESULT_OK); }
