Question

This is what my log looks like when my push notification gets called on

我目前正致力于为用户创建针对iPhone用户设置的推送通知设置。我目前正在使用Firebase，因此我自然而然地转向使用Firebase云消息传递来完成此操作。这是我在部署到Firebase的功能中的设置。我在这里做错了会导致通知没有被发送到设备吗？我感谢任何帮助，如果有任何需要的信息，我很乐意提供。

const functions = require('firebase-functions');

const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

// Listens for new messages added to messages/:pushId
exports.pushNotification =     functions.database.ref('/messages/{pushId}').onWrite( event => {

console.log('Push notification event triggered');

//  Grab the current value of what was written to the Realtime Database.
var valueObject = event.data.val();
console.log(valueObject)

if(valueObject.photoUrl != null) {
  valueObject.photoUrl= "Sent you a photo!";
}

 // Create a notification
const payload = {
    notification: {
        title:valueObject.toId, 
        body: valueObject.text || valueObject.photoUrl,
        sound: "default"
    },
};

//Create an options object that contains the time to live for the notification and the priority
const options = {
    priority: "high",
    timeToLive: 60 * 60 * 24
};
return admin.messaging().sendToTopic("pushNotifications", payload, options);
 if(!data.changed()){

});

exports.pushNotification = functions.database.ref('/messages/{pushId}').onWrite( event => {
const data = event.data;
console.log('Push notification event triggered');
return;
}



});

我注意到你暴露了两次相同的功能。这也是一个问题。另外，我建议你宣传admin.messaging，这样你就可以处理并检查错误。

let topic = "pushNotifications";
admin.messaging().sendToTopic(topic, payload, options)
        .then(function(response) {

            console.log("Successfully sent message:", response);
            console.log("Topic: " + topic);
            res.status(200).send("success");
        })
        .catch(function(error) {
            console.log("Error sending message:", error);
            res.status(500).send("failure");
        });

在registration_ids字段中的post参数上发送此jsone，您必须发布要发送推送通知的所有设备令牌的数组这是请求后方法主体

{ "registration_ids" : [Send Array of Device Token], 
  "data" :
    {
    "image_url" : "send your image here"
    "message" : "Send your message here" },
 "notification" : 
   {
    "title" : "APP Name",
    "sound" : "default",
    "priority" : "high"
   }
}

并在请求HttpHeader字段

中发送key="Your Authorization key"

此处参考云消息传递的基本设置表单

Firebase云消息传递推送通知未发送到设备
