【中文标题】为啥即使电子邮件经过验证，电子邮件验证仍然存在？【英文标题】：Why email verification still present even the email is verified?为什么即使电子邮件经过验证，电子邮件验证仍然存在？ 【发布时间】：2021-10-04 17:07:26 【问题描述】：我目前正在开发一个移动应用程序作为我最后一个学期的项目。在我的移动应用程序中，我使用 firebase 身份验证进行此电子邮件验证。这是我执行此功能的教程（如果您有兴趣）。
Firebase Login & Register App With Email | Part - 8 | Verify Email Address
我的问题是当我在我的移动应用程序中添加重置密码功能（教程的下一部分）时，即使电子邮件已验证，电子邮件验证警报仍然存在。

这是设置中的图片
我这里用来登录的邮箱在添加重置密码功能之前已经过验证。
如您所见，存在电子邮件验证警报。
【问题讨论】：
【参考方案1】：用户对象被缓存，这包括验证信息。因此，您需要将更改通知客户端，使用 java，这是通过任务完成的
带有一个 sendEmailVerification() 方法，它作为 Task 返回，用于异步发送电子邮件，并报告状态。
例如：
final FirebaseUser user = mAuth.getCurrentUser();
user.sendEmailVerification()
.addOnCompleteListener(this, new OnCompleteListener()
@Override
public void onComplete(@NonNull Task task)
// Re-enable button
findViewById(R.id.verify_email_button).setEnabled(true);
if (task.isSuccessful())
Toast.makeText(EmailPasswordActivity.this,
"Verification email sent to " + user.getEmail(),
Toast.LENGTH_SHORT).show();
else
Log.e(TAG, "sendEmailVerification", task.getException());
Toast.makeText(EmailPasswordActivity.this,
"Failed to send verification email.",
Toast.LENGTH_SHORT).show();
);
从mAuth.getCurrentUser()中获取用户，调用sendEmailVerification()方法。
