调用Firebase函数时,httpsCallable不是函数

我正在尝试使用firebase auth和firebase函数实现基于角色的身份验证。现在,我有一个按预期方式工作的注册表格,现在我正尝试添加一个表格,以便您提交一封电子邮件,该电子邮件调用firebase函数,该函数将向用户附加自定义声明。我已经通过终端将函数添加到了Firebase中,并且正在项目中调用函数,但是每当我通过电子邮件提交表单时,都可以使用httpscallable并不是函数错误。

这是我的文件

函数文件夹中的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,在其中我将所有与Firebase相关的内容称为

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();

表单所在的Vue组件

<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>

有人可以阐明为什么我会收到此错误吗?我忘了导入与Firebase相关的东西吗?

您的问题来自这样的事实

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,您没有导出fc(顺便说一下,也没有导出fv

以下应该可以工作

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,在您的组件中执行以下操作:

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

//....

或者下面的内容,您仅需要fcdb,例如:

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

//....

我可以用不同的方式解决这个问题。我正在使用 Vue 2.6。在我的组件中,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");
}

在依赖项中:

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

这基本上就是应用于 Vue.js 的文档 https://firebase.google.com/docs/functions/callable 的说明
