firebase：在注册期间发送 email 验证

Question

I tested that user is added to database but she never receive any email: what's wrong below (took it from doc https://firebase.google.com/docs/auth/web/manage-users but something missing )

function SignUp() {
    let promise = auth.createUserWithEmailAndPassword(email.value, password.value); 
    promise.catch(
        e => alert(e.message)
    );

    var user = firebase.auth().currentUser;

    user.sendEmailVerification().then(function() {
      // Email sent.
    }).catch(function(error) {
      // An error happened.
    });
}

Answer 1

You're not waiting until the sign-up is complete. To do that you can use the then part of the promise returned by createUserWithEmailAndPassword .

So:

let promise = auth.createUserWithEmailAndPassword(email.value, password.value); 
promise.then(
   userCredential => userCredential.user.sendEmailVerification()
}).catch(
    e => alert(e.message)
);
