向Firebase Cloud Functions传递参数

Question

我正在尝试编写一个Firebase Cloud函数来向用户显示推送通知。首先，我在Firebase数据库中创建通知，然后调用Firebase Cloud Function向用户发送推送通知。问题是我真的不知道如何将参数传递给云函数

我这样调用函数:

import { sendNotificationToUser, sendNotificationToNonUser } from '../../api/PushNotification';
export function createNotification(values, callback) {
return async dispatch => {
try {
...
const newNotificationRef = firestore().collection('notifications').doc(notId);
const newNotification = await firestore().runTransaction(async transaction => {
const snapshot = await transaction.get(newNotificationRef);
const data = snapshot.data();
return transaction.set(newNotificationRef, {
...data,
...values,
id: notId,
viewed: false
});
});
if (newNotification) {
if (values.reciever === null) {
sendNotificationToNonUser(values.title, values.message);
...
} else {
sendNotificationToUser(values.title, values.message, values.reciever);
...
}
} else {
...
}
} catch (e) {
...
}
};
}

然后，在PushNotification文档中，我有这个:

import axios from 'axios';
const URL_BASE = 'https://<<MyProjectName>>.cloudfunctions.net';
const Api = axios.create({
baseURL: URL_BASE
});
export function sendNotificationToNonUser(title, body) {
Api.get('sendNotificationToNonUser', {
params: { title, body }
}).catch(error => { console.log(error.response); });
}
export function sendNotificationToUser(title, body, user) {
Api.get('sendNotificationToUser', {
params: { title, body, user }
}).catch(error => { console.log(error.response); });
}

And on my Cloud Functionsindex.js

exports.sendNotificationToUser = functions.https.onRequest((data, response) => {
console.log('Params:');
});

我如何将我从PushNotifications文件发送到相应的云函数的参数?我自己对函数还是个新手

Answer 1

request, response参数(在您的示例中是data和response)本质上是Express Request和response对象。您可以使用请求的query属性来获取这些查询参数，如所示。

exports.sendNotificationToUser = functions.https.onRequest((request, response) => {
console.log('Query Params:', request.query);
// This will log the params objects passed from frontend
});

您也可以在请求正文中传递信息，然后通过云函数中的request.body访问它，但随后您必须使用POST请求。
