[英]How to configure Firebase Messaging with latest version in Flutter?
[英]Firebase messaging : how to configure serverless function
我正在尝试设置一个 vercel 函数来处理(取消)订阅 firebase 消息。 服务器端的文档很少,所以我很挣扎。
我相信我在admin.json
上有正确的服务工作人员帐户 json 但此代码失败并出现错误FirebaseError: Firebase: Need to provide options, when not being deployed to hosting via source.
import admin from 'firebase-admin';
import { initializeApp } from 'firebase-admin/app';
import serviceAccount from './admin.json' assert { type: 'json' };
import { getMessaging } from 'firebase/messaging';
export default function messaging(request, response) {
// Q1 should this be inside the function or outside?
const app = initializeApp({
credential: admin.credential.cert(serviceAccount)
});
// body is a string
let body = JSON.parse(request.body);
if (body.action === 'subscribe') {
// this is where the error is coming in
return getMessaging()
.subscribeToTopic(body.token, 'mol23-general')
.then((res) => {
response.status(200).json({ result: res });
})
.catch((error) => {
console.log('Error subscribing to topic:', error);
response.status(500).json({ error });
});
啊。 使用了错误版本的 getMessaging
import { getMessaging } from 'firebase-admin/messaging';
