[英]Allow login using username or email in Laravel 5.4
現在我已經按照 Laravel 文檔了解如何在身份驗證期間允許用戶名,但它取消了使用電子郵件的能力。 我想允許用戶使用他們的用戶名或電子郵件登錄。 我該怎么做?
我已經按照 Laravel 的文檔將此代碼添加到 LoginController 中,它只允許用戶名登錄。 我希望它接受用戶名或電子郵件進行登錄。
public function username () {
return 'username';
}
我認為更簡單的方法是覆蓋 LoginController 中的 username 方法:
public function username()
{
$login = request()->input('login');
$field = filter_var($login, FILTER_VALIDATE_EMAIL) ? 'email' : 'username';
request()->merge([$field => $login]);
return $field;
}
按照此鏈接的說明進行操作: https : //laravel.com/docs/5.4/authentication#authenticating-users
然后你可以像這樣檢查用戶輸入
$username = $request->username; //the input field has name='username' in form
if(filter_var($username, FILTER_VALIDATE_EMAIL)) {
//user sent their email
Auth::attempt(['email' => $username, 'password' => $password]);
} else {
//they sent their username instead
Auth::attempt(['username' => $username, 'password' => $password]);
}
//was any of those correct ?
if ( Auth::check() ) {
//send them where they are going
return redirect()->intended('dashboard');
}
//Nope, something wrong during authentication
return redirect()->back()->withErrors([
'credentials' => 'Please, check your credentials'
]);
這只是一個示例。 您可以采取無數種方法來完成相同的任務。
打開您的LoginController.php
文件。
添加此參考
use Illuminate\\Http\\Request;
並覆蓋憑據方法
protected function credentials(Request $request) { $field = filter_var($request->get($this->username()), FILTER_VALIDATE_EMAIL) ? 'email' : 'username'; return [ $field => $request->get($this->username()), 'password' => $request->password, ]; }
在Laravel 5.7.11 中測試成功
我認為它更簡單,只需覆蓋AuthenticatesUsers特征中的方法,您的 LoginController 中的憑據方法。 在這里,我已經實現了使用電子郵件或電話登錄。 您可以更改它以滿足您的需要。
登錄控制器.php
protected function credentials(Request $request)
{
if(is_numeric($request->get('email'))){
return ['phone'=>$request->get('email'),'password'=>$request->get('password')];
}
return $request->only($this->username(), 'password');
}
您需要從 LoginController 中的\\Illuminate\\Foundation\\Auth\\AuthenticatesUsers
Trait 覆蓋protected function attemptLogin(Request $request)
方法,即在我的 LoginController 類中
protected function attemptLogin(Request $request) {
$identity = $request->get("usernameOrEmail");
$password = $request->get("password");
return \Auth::attempt([
filter_var($identity, FILTER_VALIDATE_EMAIL) ? 'email' : 'username' => $identity,
'password' => $password
]);
}
您的 LoginController 類應該使用 Trait \\Illuminate\\Foundation\\Auth\\AuthenticatesUsers
來覆蓋attemptLogin
方法,即
class LoginController extends Controller {
use \Illuminate\Foundation\Auth\AuthenticatesUsers;
.......
.......
}
這是我這樣做的方式:
// get value of input from form (email or username in the same input)
$email_or_username = $request->input('email_or_username');
// check if $email_or_username is an email
if(filter_var($email_or_username, FILTER_VALIDATE_EMAIL)) { // user sent his email
// check if user email exists in database
$user_email = User::where('email', '=', $request->input('email_or_username'))->first();
if ($user_email) { // email exists in database
if (Auth::attempt(['email' => $email_or_username, 'password' => $request->input('password')])) {
// success
} else {
// error password
}
} else {
// error: user not found
}
} else { // user sent his username
// check if username exists in database
$username = User::where('name', '=', $request->input('email_or_username'))->first();
if ($username) { // username exists in database
if (Auth::attempt(['name' => $email_or_username, 'password' => $request->input('password')])) {
// success
} else {
// error password
}
} else {
// error: user not found
}
}
我相信有一種更短的方法可以做到這一點,但對我來說這是有效的並且很容易理解。
將此代碼添加到您的登錄控制器 - 希望它會起作用。 在一個字段中使用電子郵件或用戶名參考登錄
public function __construct()
{
$this->middleware('guest')->except('logout');
$this->username = $this->findUsername();
}
public function findUsername()
{
$login = request()->input('login');
$fieldType = filter_var($login, FILTER_VALIDATE_EMAIL) ? 'email' : 'username';
request()->merge([$fieldType => $login]);
return $fieldType;
}
public function username()
{
return $this->username;
}
public function username()
{
//return ‘identity’;
$login = request()->input('identity');
$field = filter_var($login, FILTER_VALIDATE_EMAIL) ? 'email' : 'phone';
request()->merge([$field => $login]);
return $field;
}
protected function validateLogin(Request $request)
{
$messages = [
'identity.required' => 'Email or username cannot be empty',
'email.exists' => 'Email or username already registered',
'phone.exists' => 'Phone No is already registered',
'password.required' => 'Password cannot be empty',
];
$request->validate([
'identity' => 'required|string',
'password' => 'required|string',
'email' => 'string|exists:users',
'phone' => 'numeric|exists:users',
], $messages);
}

This solution of "Rabah G" works for me in Laravel 5.2. I modified a litle but is the same
$loginType = request()->input('useroremail');
$this->username = filter_var($loginType, FILTER_VALIDATE_EMAIL) ? 'email' : 'username';
request()->merge([$this->username => $loginType]);
return property_exists($this, 'username') ? $this->username : 'email';
謝謝,這是我感謝您的解決方案。
protected function credentials(Request $request) {
$login = request()->input('email');
// Check whether username or email is being used
$field = filter_var($login, FILTER_VALIDATE_EMAIL) ? 'email' : 'user_name';
return [
$field => $request->get('email'),
'password' => $request->password,
'verified' => 1
];
}
