使用 node.js 通过条件向多个主题发送 FCM 通知的正确语法是什么？

Question

我正在尝试将 fcm 通知从我的 node.js 服务器发送到 android 设备。它适用于单个主题，但在有多个主题时会失败。

注意：使用单个主题，例如，

var topic = 'MaleFemale'; // here i have only one topic 
                var message = {
                    android: {
                        ttl: 5*60*1000, // 5 min in milliseconds
                        priority: 'normal',
                        notification: {
                        title: 'Someone want to chat',
                        body: 'Tap to join chat',
                        icon: 'stock_ticker_update',
                        color: '#2C5AE1'
                        }
                    },
                    topic: topic
                };

                send.admin.messaging().send(message)
                .then((response) => {
                // Response is a message ID string.
                console.log('Successfully sent message:', response);
                })
                .catch((error) => {
                console.log('Error sending message:', error);
                });

注意：在多个主题中失败，例如，

var topic = "'FemaleAny' in topics || 'MaleAny' in topics";//here i have multiple topic 
                var message = {
                    android: {
                        ttl: 5*60*1000, // 5 min in milliseconds
                        priority: 'normal',
                        notification: {
                        title: 'Someone want to chat',
                        body: 'Tap to join chat',
                        icon: 'stock_ticker_update',
                        color: '#2C5AE1'
                        }
                    },
                    condition: topic
                };

                send.admin.messaging().sendToCondition(message)
                .then((response) => {
                // Response is a message ID string.
                console.log('Successfully sent message:', response);
                })
                .catch((error) => {
                console.log('Error sending message:', error);
                });

错误：

throw new error_1.FirebaseMessagingError(error_1.MessagingClientErrorCode.INVALID_RECIPIENT, 'Condition provided to sendToCondition() must be a non-empty string.');
            ^

我试过了，但没有为我工作：-

1) https://firebase.google.com/docs/cloud-messaging/admin/send-messages?authuser=0

2) What is the correct syntax to send Firebase Cloud Messaging (FCM) to multiple topics via condition

这有点奇怪，我正在回答我的问题，无论如何 我通过将方法 sendToCondition() 更改为 send() 解决了问题。

var condition = "'FemaleAny' in topics || 'MaleAny' in topics";
                var message = {
                    android: {
                        ttl: 30*1000, //  30sec in milliseconds
                        priority: 'normal',
                        notification: {
                        title: 'Someone want to chat',
                        body: 'Tap to join chat',
                        icon: 'stock_ticker_update',
                        color: '#2C5AE1',
                        tag: '4'
                        }
                    },
                    condition: condition
                };

                send.admin.messaging().send(message)
                .then((response) => {
                // Response is a message ID string.
                console.log('Successfully sent message:', response);
                })
                .catch((error) => {
                console.log('Error sending message:', error);
                });
