Firebase云消息传递sendToDevice可以正常工作，但对于相同的令牌列表，sendMulticast失败 [英] Firebase cloud messaging sendToDevice works properly but sendMulticast fails for the same list of tokens
问题描述
对于某些类型的消息，我想通过FIRTokens vs主题来定位用户，这些信息存储在我的实时数据库中.我使用 async/await 加载了这些令牌，然后决定是否要将通知发送到某个主题，而不是较小的用户列表.数据加载代码按预期工作.但是奇怪的是，如果我使用 .sendMulticast(payload)，则列表中所有令牌的通知都会失败.另一方面，如果我使用 .sendToDevice(adminFIRTokens，有效负载)，则通知将成功发送给我的所有用户.现在，我的列表有2个令牌，使用 sendMulticast 我有2个失败，使用 sendToDevice 我有2个成功.我是否错过了 sendMulticast 应该做什么的要点?根据文档:将消息发送至多个设备:
For certain types of messages, I want to target users by FIRTokens vs topic, which are stored in my real-time database. I load these tokens with async/await and then decide if I want to send notifications to a topic vs a smaller list of users. The data loading code works as expected. But what's odd is that if I use .sendMulticast(payload), the notifications fail for all tokens in the list. On the other hand if I use .sendToDevice(adminFIRTokens, payload) the notification goes successfully to all my users. Right now my list has 2 tokens and with sendMulticast I have 2 failures and with sendToDevice I have 2 successes. Am I missing the point of what sendMulticast is supposed to do? According to the docs: Send messages to multiple devices:
REST API和Admin FCM API允许您将消息多播到设备注册令牌列表.每次调用最多可以指定500个设备注册令牌.
The REST API and the Admin FCM APIs allow you to multicast a message to a list of device registration tokens. You can specify up to 500 device registration tokens per invocation.
因此两者在逻辑上都应该起作用.那为什么一个失败而另一个起作用呢?实际上，通过 sendToDevice 我在响应中得到了 multicastId ！
So both should logically work. Then why does one fail and the other work? In fact with sendToDevice I get a multicastId in the response!
以下是一些控制台输出:
Here are some console outputs:
- sendToDevice:
Sent filtered message notification successfully:
{
results:
[
{ messageId: '0:1...45' },
{ messageId: '16...55' }
],
canonicalRegistrationTokenCount: 0,
failureCount: 0,
successCount: 2,
multicastId: 3008...7000
}
- sendMulticast:
List of tokens that caused failures: dJP03n-RC_Y:...MvPkTbuV,fDo1S8jPbCM:...2YETyXef

}

推荐答案
我认为这是使用其他有效负载结构的问题.
I think it's an issue of using a different payload structure.
这是旧版本(没有iOS特定信息):
This is the old one (without iOS specific info):
var payload = {
notification: {
title: title,
body: messageText,
sound: "default",
},
data: {
messageID: messageID,
messageTimestamp: messageTimestamp,
},
};
这是新版本(apns具有iOS特定信息)
Whereas this is the new version (apns has iOS specific info)
var payload = {
notification: {
title: title,
body: messageText,
},
data: {
messageID: messageID,
messageTimestamp: messageTimestamp,
},
apns: {
payload: {
aps: {
sound: "default",
},
},
},
};
使用新结构， send 和 sendMulticast 都可以正常工作.有效负载中不支持发送失败或出现诸如apns密钥之类的错误.
With the new structure, both send and sendMulticast are working properly. Which would fail to send or give errors like apns key is not supported in payload.
新功能:
functions.database
.ref("/discussionMessages/{autoId}/")
.onCreate(async (snapshot, context) => {
// console.log("Snapshot: ", snapshot);
try {
const groupsRef = admin.database().ref("people/groups");
const adminUsersRef = groupsRef.child("admin");
const filteredUsersRef = groupsRef.child("filtered");
const filteredUsersSnapshot = await filteredUsersRef.once("value");
const adminUsersSnapshot = await adminUsersRef.once("value");
var adminUsersFIRTokens = {};
var filteredUsersFIRTokens = {};
if (filteredUsersSnapshot.exists()) {
filteredUsersFIRTokens = filteredUsersSnapshot.val();
}
if (adminUsersSnapshot.exists()) {
adminUsersFIRTokens = adminUsersSnapshot.val();
}
// console.log(
// "Admin and Filtered Users: ",
// adminUsersFIRTokens,
// " ",
// filteredUsersFIRTokens
// );
const topicName = "SpeechDrillDiscussions";
const message = snapshot.val();
// console.log("Received new message: ", message);
const senderName = message.userName;
const senderCountry = message.userCountryEmoji;
const title = senderName + " " + senderCountry;
const messageText = message.message;
const messageTimestamp = message.messageTimestamp.toString();
const messageID = message.hasOwnProperty("messageID")

const isSenderFiltered = filteredUsersFIRTokens.hasOwnProperty(

messageID
);
var payload = {
notification: {

console.log("Sending filtered notification with sendMulticast()");
payload.tokens = adminFIRTokens; //Needed for sendMulticast

.messaging()
.sendMulticast(payload)
.then((response) => {
console.log(
"Sent filtered message (using sendMulticast) notification: ",
JSON.stringify(response)

if (response.failureCount > 0) {
const failedTokens = [];
response.responses.forEach((resp, idx) => {
if (!resp.success) {
