我正在修复出现的错误消息，但它以前也可以工作。我正在使用多个 token 发送 FCM 通知，但收到以下错误

产生错误的代码:
async sendToMany(users: User[], notification: VSendNotification, title = 'Title', lowPriority = false) {
// We split emails into arrays of max. 100 size because of the limitation with FCM
const userChunks = _.chunk(users, 100);
const promises = [];
userChunks.forEach(userChunk => {
const msg: admin.messaging.MulticastMessage = {
notification: {
title,
body: notification.body
},
tokens: userChunk.map(user => user.firebaseToken),
android: {
priority: lowPriority ? 'normal' : 'high'
}
};
promises.push(this.app.messaging().sendMulticast(msg));
});
const result = await Promise.all(promises);
let accepted = 0;
let rejected = 0;
result.forEach(response => {
accepted += response.successCount;
rejected += response.failureCount;
});
return { accepted, rejected, notification };
}
}
思考一下可能出了什么问题？
最佳答案
解决方案 - 避免向 Firebase 发送空的 fcm token 。
我找到了解决方案。我列出了所有的 firebase token ，并且我的数据库中有一些空 token ，这是主要问题。
当我们发送空的 fcm token 时，Firebase 会给出以下错误
Exactly one of topic, token or condition is required
关于javascript - Firebase 管理 SDK FCM 错误 需要主题、 token 或条件之一，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60170040/
