Laravel 4 Auth::attempt using either email or username and password
提问by Chinmoy
In laravel for login attempt I generally use something like this:
在 Laravel 中进行登录尝试，我通常使用这样的方法：
if (Auth::attempt(array('email' => $usernameinput, 'password' => $password), true))
{
// The user is being remembered...
}
Basically $usernameinputwill check with emailfrom my table.
基本上$usernameinput会email从我的桌子上检查。
I was thinking to do it in a different way, like there is email, usernameand passwordin my table. $usernameinputcan be either emailor usernamefield in my table.
我想以不同的方式来做，就像有email,username和password在我的桌子上。$usernameinput可以是我的表中的email或username字段。
How can I Auth::attemptwith a condition like:
我怎么能Auth::attempt有这样的条件：
(email==$usernameinput OR username==$usernameinput) AND password == $password

Well, you could simply check if $usernameinputmatches an email pattern and if it does, use the emailfield, else use the usernamefield. This sounds reasonable because, well, you really shouldn't have any e-mail in your database that doesn't match the pattern. Something like this:
好吧，您可以简单地检查是否$usernameinput与电子邮件模式匹配，如果匹配，则使用该email字段，否则使用该username字段。这听起来很合理，因为您的数据库中确实不应该有任何与模式不匹配的电子邮件。像这样的东西：
$field = filter_var($usernameinput, FILTER_VALIDATE_EMAIL) ? 'email' : 'username';
if (Auth::attempt([$field => $usernameinput, 'password' => $password], true)) {
// ...
}
The other option is to extend Illuminate\Auth\Guardadding the wanted functionality and setting it as the authcomponent, in a new service provider.
另一种选择是在新的服务提供者中扩展Illuminate\Auth\Guard添加所需的功能并将其设置为auth组件。

It can be done something like this
它可以做这样的事情
$field = Validator::make(array('email' => $usernameinput, array('email' => 'email'))->passes() ? 'email' : 'username';
if (Auth::attempt(array($field => $usernameinput, 'password' => $password), true)) {
return Redirect::intended('profile');
}

Users could use an email field as their username, and it might not match the email they used for the email field. Safer to attempt authentication twice:
用户可以使用电子邮件字段作为他们的用户名，但它可能与他们用于电子邮件字段的电子邮件不匹配。尝试两次身份验证更安全：
if (Auth::attempt(array(
'email' => Input::get('email_or_username'),
'password' => Input::get('password')
)) ||
Auth::attempt(array(
'username' => Input::get('email_or_username'),
'password' => Input::get('password')
))) {
// SUCCESS
} else {
// FAILURE
}

Here's the complete working solution: (Tested with Laravel 5.3)
这是完整的工作解决方案：（用 Laravel 5.3 测试）
Just add this method(or we can say override) into app\Http\Controllers\Auth\LoginController.php
只需将此方法（或者我们可以说是覆盖）添加到app\Http\Controllers\Auth\LoginController.php
public function login(Request $request)
{
$usernameinput = $request->input('email');
$password = $request->input('password');
$field = filter_var($usernameinput, FILTER_VALIDATE_EMAIL) ? 'email' : 'username';
if (Auth::attempt([$field => $usernameinput, 'password' => $password])) {
return redirect()->intended('/');
} else {
return $this->sendFailedLoginResponse($request);
}
}
