未发送Firebase WEB电子邮件验证。代码出了什么问题

Question

嗯，我已经尝试了多种方法来触发sendeMailVerification()函数。但没有一个成功。医生也帮不上忙。

下面是我将要使用的部分源代码。请让我知道我可以如何纠正这一点。

在我的控制台上,我得到以下错误：

TypeError：无法读取Object.Firebase.auth.OnauthStateChanged.FirebaseUser[as next]中为null的属性“email verified”

        btnSignUpWithGoogle.addEventListener('click', e => {
            var provider = new firebase.auth.GoogleAuthProvider();

            firebase.auth().signInWithPopup(provider).then(function(result) {
            var token = result.credential.accessToken;
            var user = result.user;
          }).catch(function(error) {
            var errorCode = error.code;
            var errorMessage = error.message;
            var email = error.email;
            var credential = error.credential;
            console.log(errorCode);
          });
    });

    btnLogin.addEventListener('click', e => {
      const email = txtEmail.value;
      const pass = txtPassword.value;
      const auth = firebase.auth();

      const promise = auth.signInWithEmailAndPassword(email, pass);
      promise.catch(e => console.log(e.message));

      txtEmail.value = "";
      txtPassword.value = "";
    });

    btnSignUp.addEventListener('click', e => {
      const email = txtEmail.value;
      const pass = txtPassword.value;
      const auth = firebase.auth();

      const promise = auth.createUserWithEmailAndPassword(email, pass);
      promise.catch(e => console.log(e.message));

      txtEmail.value = "";
      txtPassword.value = "";

      const emailVerified = firebaseUser.emailVerified;

      if (!emailVerified){
        firebase.auth().firebaseUser.sendEmailVerification().then(function(){
          alert('Please check your email to verify your Account.');
        });
      } else {
        alert('Your Email has been verified!');
      }

    });

    firebase.auth().onAuthStateChanged(firebaseUser => {
      if (firebaseUser) {
        console.log(firebaseUser);
        console.log('Logged IN!');
        btnLogout.style.visibility = 'visible';
    }
      if (firebaseUser.emailVerified) {
        console.log('Email is verified');
      }
      else {
        console.log('Email is not verified');
        firebaseUser.sendEmailVerification();
      }

    });

Answer 1

sendEmailVerification（）仅在您已经将电子邮件地址加载到FireBase中时才起作用。

查看下面的代码：https://github.com/aqeelsmith/angularjsdata/blob/master/builds/angulardata/js/services/authentication.js-行82

Answer 2

我们能看看所有的代码吗？您确定您的firebase.auth（）声明正确吗？

您的身份验证应该如下所示：

const firebaseApp = firebase.initializeApp(firebaseConfig, 'Client');
const firebaseAuth = firebaseApp.auth();

firebaseUser应该有emailVerified将if else语句移动到if firebaseUser内部，如下所示：

firebase.auth().onAuthStateChanged(firebaseUser => {
  if (firebaseUser) {
    console.log(firebaseUser);
    console.log('Logged IN!');
    btnLogout.style.visibility = 'visible';

    if (firebaseUser.emailVerified) {
      console.log('Email is verified');
    }
    else {
      console.log('Email is not verified');
      firebaseUser.sendEmailVerification();
    }

  }

});

console.log(firebaseUser)，是怎么说的？
