我正在使用Firebase的电子邮件和密码方法注册我的用户。像这样：
mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
FirebaseUser signed = task.getResult().getUser();
writeNewUser(signed.getUid());
new android.os.Handler().postDelayed(
new Runnable() {
public void run() {
updateUser(b);
}
}, 3000);
} else {
new android.os.Handler().postDelayed(
new Runnable() {
public void run() {
onSignupFailed();
}
}, 3000);
}
}
});
用户的电子邮件注册成功后，我希望Firebase发送验证邮件。我知道这可以使用Firebase的sendEmailVerification。除了发送此电子邮件之外，我希望在验证电子邮件之前禁用该用户的帐户。这还需要使用Firebase的isEmailVerified功能。但是，我没有成功让Firebase发送验证电子邮件，我无法弄清楚是否要禁用并启用发送验证电子邮件的帐户以及验证后的电子邮件。

此问题是关于如何使用Firebase发送验证邮件。 OP无法弄清楚如何禁用和启用发送验证电子邮件的帐户以及验证后的电子邮件。
此外，firebase文档中没有正确记录这一点。所以我正在编写一个有步骤的程序，如果他/她面临问题，可能会有人跟进。
1）用户可以使用createUserWithEmailAndPassword方法。
示例：
mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
Log.d("TAG", "createUserWithEmail:onComplete:" + task.isSuccessful());
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
// Show the message task.getException()
}
else
{
// successfully account created
// now the AuthStateListener runs the onAuthStateChanged callback
}
// ...
}
});
如果创建了新帐户，则用户也会登录，并且AuthStateListener会运行onAuthStateChanged回调。在回调中，您可以管理向用户发送验证电子邮件的工作。
示例：
onCreate(...//
mAuthListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
// User is signed in
// NOTE: this Activity should get onpen only when the user is not signed in, otherwise
// the user will receive another verification email.
sendVerificationEmail();
} else {
// User is signed out
}
// ...
}
};
现在发送验证邮件可以写成：
private void sendVerificationEmail()
{
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
user.sendEmailVerification()
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
// email sent
// after email is sent just logout the user and finish this activity
FirebaseAuth.getInstance().signOut();
startActivity(new Intent(SignupActivity.this, LoginActivity.class));
finish();
}
else
{
// email not sent, so display message and restart the activity or do whatever you wish to do
//restart this activity
overridePendingTransition(0, 0);
finish();
overridePendingTransition(0, 0);
startActivity(getIntent());
}
}
});
}
现在登陆LoginActivity：
如果用户成功登录，那么我们只需调用一个方法来编写逻辑，以检查电子邮件是否已经过验证。
示例：
mAuth.signInWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
//Log.d("TAG", "signInWithEmail:onComplete:" + task.isSuccessful());
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
//Log.w("TAG", "signInWithEmail:failed", task.getException());
} else {
checkIfEmailVerified();
}
// ...
}
});
现在考虑checkIfEmailVerified方法：
private void checkIfEmailVerified()
{
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if (user.isEmailVerified())
{
// user is verified, so you can finish this activity or send user to activity which you want.
finish();
Toast.makeText(LoginActivity.this, "Successfully logged in", Toast.LENGTH_SHORT).show();
}
else
{
// email is not verified, so just prompt the message to the user and restart this activity.
// NOTE: don't forget to log out the user.
FirebaseAuth.getInstance().signOut();
//restart this activity
}
}
所以我在这里检查电子邮件是否已经过验证。如果没有，请注销用户。
所以这是我正确跟踪事情的方法。
答案 1 :(得分：4)
使用FirebaseAuth.getInstance().getCurrentUser().sendEmailVerification()和FirebaseAuth.getInstance().getCurrentUser().isEmailVerified()
无法通过Firebase SDK停用该帐户。您可以使用包含Firebase身份验证令牌的GetTokenResult并根据您的自定义后端对其进行验证，或者为该用户对应的Firebase数据库设置一个标志。就个人而言，我会使用Firebase数据库中的标志
答案 2 :(得分：3)
将验证发送到用户的电子邮件
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
user.sendEmailVerification();
检查用户是否已经过验证
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
boolean emailVerified = user.isEmailVerified();
答案 3 :(得分：1)
要首先使用Firebase发送电子邮件链接，您需要获取FirebaseAuth实例 使用我们通过以下方式在Firebase上创建用户的实例：
firebaseauth.createUserWithEmailAndPassword(email,pass);
方法成功返回后，我们将使用Firebase用户实例向用户发送验证链接：
final FirebaseUser user = mAuth.getCurrentUser();
user.sendEmailVerification()
答案 4 :(得分：0)
mAuth.createUserWithEmailAndPassword(email,password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if(task.isSuccessful()){
mAuth.getCurrentUser().sendEmailVerification().addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Toast.makeText(this, "please check email for verification.", Toast.LENGTH_SHORT).show();
loadingBar.dismiss();
}else{
Toast.makeText(this, task.getException().getMessage() , Toast.LENGTH_SHORT).show();
}
}
});

对于 Kotlin
val user: FirebaseUser? = firebaseAuth.currentUser
user?.sendEmailVerification()
