<form action="register.php" method="post">
  <label for="email">请填写您的邮箱:</label>
  <input type="email" name="email" id="email">
  <input type="submit" value="注册">
</form>
  1. Write an email sending method

In the background code, you need to write A method for sending verification emails. You can use a third-party email sending library such as PHPMailer, or you can use PHP's built-in email sending function mail(). The email content should contain a verification link for users to click to jump to the verification page to verify the user's email address.

public function sendVerifyEmail($to, $token)
{
    $url = 'http://example.com/verify.php?token=' . $token;
    $body = <<<EOT
    尊敬的用户,您好!
    
    感谢您在我站注册了新账户。
    
    请点击此链接验证您的邮箱地址:
    
    {$url}
    
    若您没有进行过此操作,请忽略此邮件。
    
    – 您的好友
    EOT;
    
    $mail->addAddress($to);
    $mail->Subject = '请验证您的email';
    $mail->Body = $body;
    $mail->send();
}

Route::get('email-verification/:token', 'User/emailVerification');
  1. Write email verification method

In the background code, you need to write a method for email verification, which is used to verify the user's email address. After successful verification, the user's email verification status needs to be updated to the database so that other pages can determine whether the user has passed email verification.

public function emailVerification($token)
{
    $user = User::where('email_token', $token)->first();
    if (!$user) {
        abort(404);
    }
    
    $user->email_verified = true;
    $user->email_token = null;
    $user->save();
    
    return redirect('/login')->with('success', '邮箱验证成功!请登录');
}
  1. Integrated email verification

When registering a user, the user's email address and a randomly generated verification token need to be stored in the database. Subsequently, call the send email method written above to send a verification email to the user's email address. When the user clicks the link in the verification email, the system will access the verification page and execute the email verification method.

public function register(Request $request)
{
    $this->validate($request, [
        'email' => 'required|email|unique:users,email',
        'password' => 'required|min:6'
    ]);
    
    $user = User::create([
        'email' => $request->email,
        'password' => bcrypt($request->password),
        'email_token' => str_random(32)
    ]);
    
    $this->sendVerifyEmail($user->email, $user->email_token);
    
    return redirect('/login')->with('success', '新用户注册成功!请前往您的邮箱验证。');
}
