httpsCallable 在調用 Firebase function 時不是 function

Question

我正在嘗試使用 Firebase auth 和 Firebase 函數實現基於角色的身份驗證。 現在我有一個按預期工作的注冊表單，現在我正在嘗試添加一個表單，您提交一個 email 調用 Firebase function 用戶將附加自定義聲明。 I already added my function to Firebase via the terminal and I'm calling functions on my project but whenever I submit the form with the email I get a httpsCallable is not a function error.

這是我的文件：

函數文件夾中的index.js

const functions = require("firebase-functions");
const admin = require("firebase-admin");
admin.initializeApp();

exports.addAdminRole = functions.https.onCall((data, context) => {
  //get user and add custom claim (admin)
  return admin
    .auth()
    .getUserByEmail(data.email)
    .then(user => {
      return admin.auth().setCustomUserClaims(user.uid, {
        admin: true
      });
    })
    .then(() => {
      return {
        message: `Success! ${data.email} has been made admin`
      };
    })
    .catch(err => {
      return err;
    });
});

我的firebaseInit.js配置文件，我在其中調用與 firebase 相關的所有內容

import firebase from "firebase/app";
import "firebase/firestore";
import "@firebase/functions";
import firebaseConfig from "./firebaseConfig";
const firebaseApp = firebase.initializeApp(firebaseConfig);

export const fc = firebase.functions();
export const db = firebase.firestore();
export const fv = firebase.firestore.FieldValue;

export default firebaseApp.firestore();

還有表單所在的Vue組件

<template>
  <div class="home">
    <h3>Welcome to Site</h3>

    <h3>Add user to admin</h3>
    <div class="row">
      <form @submit.prevent="addAdmin()" class="col s12">
        <div class="row">
          <div class="input-field col s12">
            <input id="email" type="email" class="validate" v-model="email" />
            <label for="email">Email</label>
          </div>
        </div>
        <button type="submit" class="btn">Submit</button>
        <router-link to="/members" class="btn grey">Cancel</router-link>
      </form>
    </div>
  </div>
</template>

<script>
import firebase from "firebase/app";
import fc from "../data/firebaseInit";
export default {
  name: "home",
  data() {
    return {
      email: ""
    };
  },
  methods: {
    addAdmin() {
      const addAdminRole = fc.httpsCallable("addAdminRole");
      addAdminRole(this.email).then(result => {
        console.log(result);
      });
    }
  }
};
</script>

有人可以解釋為什么我會收到這個錯誤嗎？ 我是否忘記導入與 firebase 相關的內容？

Answer 1

你的問題來自這樣一個事實

export const fc = firebase.functions();
export const db = firebase.firestore();
export const fv = firebase.firestore.FieldValue;

export default firebaseApp.firestore();

在您的firebaseInit.js文件中，您沒有導出fc （順便說一下fv ）

以下應該工作

import firebase from "firebase/app";
import "firebase/firestore";
import "firebase/functions";   // <-- Note that the @ was removed
import firebaseConfig from "./firebaseConfig";
const firebaseApp = firebase.initializeApp(firebaseConfig);

const fc = firebase.functions();
const db = firebase.firestore();
const fv = firebase.firestore.FieldValue;

export { fc, db, fv };

然后，在您的組件中執行以下操作：

import {fc, db, fv} from "../data/firebaseInit";

//....

或者下面你只需要fc和db ，例如：

import {fc, db} from "../data/firebaseInit";

//....

我可以用不同的方式解決這個問題。 我正在使用 Vue 2.6。 在我的組件中，我只需要：

import firebase from "firebase/app";
const functions = firebase.functions();
var addMessage = functions.httpsCallable("addMessage");

在我的 main.js 文件中，我有：

import Vue from "vue";
import App from "./App.vue";
import vuetify from "./plugins/vuetify";
import router from "./router";
import firebase from "firebase/app";
import "firebase/functions";
import store from "./store";

Vue.config.productionTip = false;
Vue.config.devtools = true;

Vue.prototype.$firebase = firebase;

// Your web app's Firebase configuration
const firebaseConfig = {

};
// Initialize Firebase
firebase.initializeApp(firebaseConfig);

let app;

firebase.auth().onAuthStateChanged(user => {
  if (!app) {
    app = new Vue({
    router,
    store,
    render: h => h(App)
  }).$mount("#app");
}

在依賴項中：

"dependencies": {
   "core-js": "^3.6.5",
    "firebase": "^8.0.2",
    "firebase-functions": "^3.13.2",
    ...
 }

這基本上是適用於 Vue.js 的文檔https://firebase.google.com/docs/functions/callable的說明

我認為問題來自於你這樣做的事實

import firebase from "firebase/app";
import "firebase/firestore";
import "@firebase/functions";

而你應該這樣做：

import firebase from "firebase/app";
import "firebase/firestore";
import "firebase/functions";    //<-- Change here
