如何在laravel 5.2中向登录函数添加到期日条件

在Laravel5.2中，我想添加一个条件，以便只有到期日大于今天日期的用户才能登录

protected function getCredentials(Request $request)
{

return ['email' => $request->{$this->loginUsername()}, 'password' => $request->password];

}

代码不接受添加： “过期”=>gte（碳：：现在（）

---

非常感谢任何帮助

我认为这是不可能的，即使是在Laravel 5.5中。查看

light\Auth\EloquentUserProvider

中用于从数据库获取用户的

retrieveByCredentials

方法，可以看到查询将简单的键/值组合传递到

$query

对象上的

where

方法，该方法等同于

where key=value

。这是第5.5节：

public function retrieveByCredentials(array $credentials)
{
    if (empty($credentials) ||
       (count($credentials) === 1 &&
        array_key_exists('password', $credentials))) {
        return;
    }

    // First we will add each credential element to the query as a where clause.
    // Then we can execute the query and, if we found a user, return it in a
    // Eloquent User "model" that will be utilized by the Guard instances.
    $query = $this->createModel()->newQuery();

    foreach ($credentials as $key => $value) {
        if (! Str::contains($key, 'password')) {
            $query->where($key, $value);
        }
    }

    return $query->first();
}

为了实现您的目标，我建议在用户登录后进行此检查，例如在控制器中：

// Imagine this is the controller method where you're dealing with user logins
public function login(array $credentials)
{
    if (! auth()->attempt($credentials)) {
        // Handle what happens if the users credentials are incorrect.
    }

    $user = auth()->user();

    if (Carbon::now()->gte($user->expires)) {
        // User's account has expired, lets log them out.
        auth()->logout();

        // Return a redirect with a message or something...
    }

    // Handle a successful login.
}

我不确定5.2中是否提供了

auth（）

帮助程序，但您应该能够使用

auth

外观执行相同的操作，例如

auth:：trust（…）
