我有一个专门为前端构建的角度应用程序，其中Akveo / ngx-admin用作构建前端的模板。现在，我有一个包含多个字段和复选框的表单，我想将该表单数据发送到Firestore云中，但后端是使用nodejs云函数创建的。所以我想用表单数据作为参数调用nodejs内部的函数，并将该数据添加到firestore中。我是Firebase云功能的初学者，所以我真的很喜欢一个解释或一点点代码帮助

nodejs应用中的index.js文件
var admin = require("firebase-admin");
const functions = require('firebase-functions');
var fetch = require("node-fetch");
var serviceAccount = require("../xxxxxxxxxxxxxxxxxxxxxxxxxxxx.json");
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "https://xxxxxxxxxxxxxx.firebaseio.com"
});
const db = admin.firestore();
我还没有在nodejs中编写post数据函数，但我想事先知道如何从angular调用该函数
