Firebase 未与反应应用程序连接

Question

import React, { useRef, useState } from "react"
import { Form, Button, Card, Alert } from "react-bootstrap"
import { useAuth } from "../contexts/AuthContext"
import { Link, useNavigate} from "react-router-dom"

export default function Signup() {
  const emailRef = useRef()
  const passwordRef = useRef()
  const passwordConfirmRef = useRef()
  const { signup } = useAuth()
  const [error, setError] = useState("")
  const [loading, setLoading] = useState(false)
  const history = useNavigate()

  async function handleSubmit(e) {
    e.preventDefault()

    if (passwordRef.current.value !== passwordConfirmRef.current.value) {
      return setError("Passwords do not match")
    }

    try {
      setError("")
      setLoading(true)
      await signup(emailRef.current.value, passwordRef.current.value)
      history.push("/")
    } catch {
      setError("Failed to create an account")
    }

    setLoading(false)
  }

  return (
    <>
      <Card>
        <Card.Body>
          <h2 className="text-center mb-4">Sign Up</h2>
          {error && <Alert variant="danger">{error}</Alert>}
          <Form onSubmit={handleSubmit}>
            <Form.Group id="email">
              <Form.Label>Email</Form.Label>
              <Form.Control type="email" ref={emailRef} required />
            </Form.Group>
            <Form.Group id="password">
              <Form.Label>Password</Form.Label>
              <Form.Control type="password" ref={passwordRef} required />
            </Form.Group>
            <Form.Group id="password-confirm">
              <Form.Label>Password Confirmation</Form.Label>
              <Form.Control type="password" ref={passwordConfirmRef} required />
            </Form.Group>
            <Button disabled={loading} className="w-100" type="submit">
              Sign Up
            </Button>
          </Form>
        </Card.Body>
      </Card>
      <div className="w-100 text-center mt-2">
        Already have an account? <Link to="/login">Log In</Link>
      </div>
    </>
  )
}

我正在尝试创建一个与我的 firebase.js 文件连接的注册页面，但每当我尝试创建用户时，它总是会抛出错误“无法创建帐户”。

我尝试的是：

• 更改了授权密钥
• 在 firebase 用户中再次删除或添加本地主机
• 问题依然存在

import React, { useContext, useState, useEffect } from "react"
import { auth } from "../firebase"

const AuthContext = React.createContext()

export function useAuth() {
    return useContext(AuthContext)
  }

export function AuthProvider({ children }) { 
    const [currentUser, setCurrentUser] = useState()
    const [loading, setLoading] = useState(true)


    function signup(email, password) {
        return auth.createUserWithEmailAndPassword(email, password)
    }


    useEffect(() => {
        const unsubscribe = auth.onAuthStateChanged(user => {
            setCurrentUser(user)
            setLoading(false)
        })

        return unsubscribe
    }, [])

    const value = {
        currentUser,
        // login,
        signup,
        // logout,
        // resetPassword,
        // updateEmail,
        // updatePassword
      }
    

    return (
        <AuthContext.Provider value={value}>
            {!loading && children}
        </AuthContext.Provider>
    )

}

这是我的 AuthContext.js 文件，但仍然不确定。

下面是我的 firebase.js 文件。

import "firebase/auth"
import { initializeApp } from "firebase/app";

import { getAuth } from "firebase/auth";


const app = initializeApp({
    apiKey: 
    authDomain: ,
    projectId: ,
    storageBucket: ,
    messagingSenderId:,
    appId: 
})


export const auth = getAuth(app);
export default app

我已经删除了信用信息，所以我仍然不确定问题所在

这是一个使用 firebase 注册新用户的工作函数。 （我将其放在一个自定义挂钩中，我在注册页面上调用该挂钩）。

    const signUpWithEmailAndPassword = (formData) => {
    const { email, password, displayName } = formData;
    createUserWithEmailAndPassword(auth, email, password, displayName)
        .then((userCredential) => {
            // Signed in
            const user = userCredential?.user;
            const uid = userCredential?.user?.uid;
                loginService(uid, user); //this is where you would dispatch your login service which can be reused with your other sign-in options (Google/Facebook/etc)
        })
        .catch((error) => {
            alert(error.message);
            console.log(
                'Error Signing Up with Email & Password. Error Message: ',
                error.message
            );
        });
};

我也同意德鲁的观点，虽然提供的信息不足以调试您的代码，但问题似乎出在您的上下文中。我建议您尝试使用上述功能创建一个新用户并记录结果，如果有效，那么您可以开始调试您的上下文。

祝你好运！
