Cloud Functions with Firebase: signInWithEmailAndPassword is not a function

Question

I'm beginning writing code with Cloud Functions with Firebase . Of the functions below, testCreateUserAccount succeeds. testLogin fails with a Type Error at runtime, stating " signInWithEmailAndPassword is not a function "

From what I have seen in the documentation, createUser is under the same class as signInWithEmailAndPassword , so its not clear to me why attempting to call signInWithEmailAndPassword would fail. Any ideas? Thanks!

"use strict"; 

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

admin.initializeApp(functions.config().firebase);   

exports.testCreateUserAccount = functions.https.onRequest ((req, res) => {
    var email = "joe@example.com";
    var password = "joejoe";

    admin.auth().createUser({
      email: email,
      password: password,
      disabled: false
    });
} );


exports.testLogin = functions.https.onRequest ((req, res) => {
    var email = "joe@example.com";
    var password = "joejoe";

    admin.auth().signInWithEmailAndPassword(email, password);
} );

Answer 1

您在服务器端使用了admin.auth().signInWithEmailAndPassword(email, password) ，您必须在客户端使用它。

Answer 2

Now you could use the identitytoolkit's rest endpoint:

https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=[API_KEY]

Here you have the documentation:

https://firebase.google.com/docs/reference/rest/auth/

Answer 3

You can use Identity toolkit REST API like this then response with idToken. IdToken can be use to verify an account using admin.auth().verifyIdToken(idToken) in Cloud Function.
