注意:处理单个主题,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,但没有成功:-

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

有点奇怪,反正我是在回答我的问题我通过改变方法解决了问题 sendToCondition() send() .

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);
                });
