发送电子邮件验证 link 在 firebase auth expo 中不起作用

Question

我正在尝试创建一个只能使用现有电子邮件的注册系统。我正在尝试在他们按下按钮后向电子邮件发送电子邮件验证 link，如果通过验证，则会创建用户。这是我的功能：

userSignUp = (emailID,password,confirmPassword) => {
    if(password !== confirmPassword) {
        return alert("Password does not match. \n Check your password.")
    }  
    else if(this.state.firstName !== '' &&
            this.state.lastName !== ''  &&
            this.state.emailID !== '' &&
            this.state.password !== ''){
        
        alert('A mail has been sent to your email account. Verify it and you will be able to login.');

        return firebase.auth().currentUser.sendEmailVerification()
        .then(() => {
            if(authUser.user.emailVerified){ //This will return true or false
                firebase.auth().createUserWithEmailAndPassword(emailID, password)
                .then(()=>{
                    //console.log(this.state)
                  db.collection("Users").add({
                      'firstName': this.state.firstName,
                      'lastName': this.state.lastName,
                      'contact': this.state.contact,
                      'emailID': this.state.emailID,
                      'password': this.state.password,
                      'points': 0,
                      'description': ''
                  })
                  return alert('Account has been created. You can now login.');
                })
                .catch((error) => {
                  // Handle Errors here.
                  var errorCode = error.code;
                  var errorMessage = error.message;
                  return alert(errorMessage);
                });
            } else {
                 return alert('Verification failed. Failed to create account.')
            }
        });
      
    }
    else if(this.state.firstName === ''){
        return alert("Please enter your first name.");
    }
    else if(this.state.lastName === ''){
        return alert("Please enter your last name.");
    }
    else if(this.state.emailID === ''){
        return alert("Please enter your email address.");
    }
    else if(this.state.password === ''){
        return alert("Please enter your password.");
    }
  }

顺便说一句，我也遇到了这个错误

TypeError: null 不是对象（正在计算 'firebase.default.auth().currentUser.sendEmailVerification'）

有没有其他方法可以验证电子邮件是否存在。我正在 javascript 使用 expo 客户端。谁能帮帮我吗？谢谢

用户必须登录才能请求验证电子邮件。看来您正在尝试在登录用户之前验证用户的电子邮件，甚至首先创建他们的帐户，这目前是不可能的。所以流程应该是：

// 1. Create user account / log user in
firebase.auth().createUserWithEmailAndPassword(emailID, password).then(async ({user}) => {
  // 2. Send verification email
  await user.sendEmailVerification()
  console.log("Verification email sent!")  
})

您可以在应用程序中使用 emailVerified 属性来提醒用户是否尚未验证电子邮件并使用安全规则限制他们的访问。也结账：
