Question

在laravel 5.2中，我想添加条件，以便只有用户的有效期限大于今天的登录日期。

protected function getCredentials(Request $request)
{

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

}

代码不接受添加：＆＃39;到期＆＃39; =＆GT; GTE（碳::现在（））

感谢任何帮助

即使在Laravel 5.5中，我也不认为这是可能的。看一下retrieveByCredentials中用于从数据库中获取用户的Illuminate\Auth\EloquentUserProvider方法，您可以看到查询将简单的键/值组合传递给where方法$query对象，等同于where key = value。这是从5.5：

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，我建议您在用户登录之后检查，例如在您的控制器中：

// 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auth()帮助程序是否在5.2中可用，但您应该可以使用Auth外观来执行相同的操作，例如Auth::attempt(...)。
