如何检索Laravel护照访问令牌过期时间或日期时间？

Question

我用的是Laravel 5.4和Passport 4。我只想使用第一方应用程序。因此，正如这个答案所建议的，我不想把ClientID和ClientSecret放在应用程序中。我已经输入了AuthServiceProvider的boot（）方法：

Passport::routes();
Passport::tokensExpireIn(Carbon::now()->addDays(30));
Passport::refreshTokensExpireIn(Carbon::now()->addDays(60));

我在api中添加了自己的路由。php接受应用程序登录：

Route::post('login', 'Auth\LoginController@apiLogin');

这是我的行动：

public function apiLogin(Request $request)
{
    $credentials = $request->only('email', 'password');

    if (Auth::attempt($credentials)) {
        // Authentication passed...
        $user = Auth::user();
        $token = $user->createToken('API Access')->accessToken;

        return response()->json(["token_type" =>"Bearer","expires_in" => 2592000,"access_token" => $token]);
    }

    return response()->json(["error" => "invalid_credentials", "message" => "The user credentials were incorrect."], 401);
}

是否有任何方法可以检索在中过期的秒数（30天）=

<?php
//...
use Laravel\Passport\Bridge\PersonalAccessGrant;
use League\OAuth2\Server\AuthorizationServer;
//...

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     */
    public function boot()
    {
        // http://php.net/manual/zh/dateinterval.construct.php
        $lifetime = new \DateInterval('P1W');

        $this->app->get(AuthorizationServer::class)
              ->enableGrantType(
                 new PersonalAccessGrant(), 
                 $lifetime
              );
    }

    //...
}
//...

下面是我如何设法从对象中获得它：

正如蒂姆·刘易斯在评论中指出的，有一个$令牌属性，$user-

public function apiLogin(Request $request)
{
    $credentials = $request->only('email', 'password');

    if (Auth::attempt($credentials)) {
        // Authentication passed...

        Passport::tokensExpireIn(Carbon::now()->addDays(30));
        Passport::refreshTokensExpireIn(Carbon::now()->addDays(60));

        $user = Auth::user();
        $objToken = $user->createToken('API Access');
        $strToken = $objToken->accessToken;

        $expiration = $objToken->token->expires_at->diffInSeconds(Carbon::now());

        return response()->json(["token_type" => "Bearer", "expires_in" => $expiration, "access_token" => $strToken]);
    }

    return response()->json(["error" => "invalid_credentials", "message" => "The user credentials were incorrect."], 401);
}

但是，如果在AuthServiceProvider引导（）中使用这两行，请小心：

Passport::tokensExpireIn(Carbon::now()->addDays(30));
Passport::refreshTokensExpireIn(Carbon::now()->addDays(60));

因为根据这个Laravel护照问题，它不会在Laravel 5.4的密码授予类型中用个人访问令牌替换到期。
