在app.js中导入firebase后,我进行了初始化,但在控制器firebase.auth.createUserWithEmailAndPassword中则不是函数

问题描述

这是在我的app.js中,我在其中导入Firebase并将其初始化

    const firebase = require('firebase');

    firebase.initializeApp({
      apiKey: ************,authDomain: ****************,databaseURL: **********",projectId: ********,storageBucket: ***********,messagingSenderId: **********,appId: *********,measurementId: *********
    });

    app.use( (req,res,next) => {
      firebase.auth().onAuthStateChanged(function(user) {
        if (user) {
            req.session.isLoggedIn = true;
        } else {
            req.session.isLoggedIn = false;
        }
      });
      res.locals.isAuthed = req.session.isLoggedIn;
      res.locals.csrftoken = req.csrftoken();
      next();
    });

但是在导入Firebase之后的auth.js控制器中,它将无法正常工作

    const firebase = require('firebase');

    exports.postSignup = (req,next) => {
     const name = req.body.name;
     const email = req.body.email;
     const password = req.body.password;
     const confirmPassword = req.body.password;

     if(password === confirmPassword){
        
        firebase.auth().createuserWithEmailAndPassword(email,password)
        .then(function(firebaseUser) {
            const user = new User({
                name: name,email: email,cart: {items: []}
            });
            return user.save();
        })
        .then(result => {
            res.redirect('/login');
        })
        .catch(error => {
            if (error.code == 'auth/email-already-in-use') {
                //'auth/wrong-password'
                req.flash('error','Already Registered');
                return res.redirect('/signup');
            }
        });  
    }

发生此错误 TypeError:firebase.auth.createuserWithEmailAndPassword不是一个函数 在exports.postSignup(/ media / rishav / Project Space / Projects / Web Development / Node Express / Controllers / auth.js:95:23)

    const firebase = require('firebase-admin');

    // Fetch the service account key JSON file contents
    const serviceAccount = require("../Data/firebase-service-account.json");

    // Initialize the app with a service account,granting admin privileges
    firebase.initializeApp({
      credential: firebase.credential.cert(serviceAccount),databaseURL: "****",databaseAuthVariableOverride: null
    });

解决方法

您可能想说:

firebase.auth().createUserWithEmailAndPassword(...)

在“ auth”之后注意括号。

但是更大的问题是,您不应该在nodejs应用程序中使用Firebase Web客户端库。相反,您应该使用Firebase Admin SDK,这是一个完全不同的模块,并以服务帐户初始化的管理员权限运行。您可以在后端代码中将其用于create user accounts
