如何检索 Laravel Passport 访问令牌有效期或日期时间？

How to retrieve Laravel Passport access token expiration duration or datetime?

提问by KeitelDOG

I'm using Laravel 5.4 and Passport 4. I want to use only First-Party-Apponly. So as suggested from this answer, I want to stay away from putting the ClientID and ClientSecret in the App. I have put in boot()method of AuthServiceProvider:

我正在使用 Laravel 5.4 和 Passport 4。我只想使用First-Party-App。所以正如这个答案所建议的那样，我想远离将 ClientID 和 ClientSecret 放在应用程序中。我已经采用了以下boot()方法AuthServiceProvider：

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

I added my own route in api.phpto accept login from App :

我添加了自己的路由api.php以接受来自 App 的登录：

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

This is my Action :

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);
}

Is there any method to retrieve the number of seconds for expires_in(30 days => 2592000s), or the datetime so I could make the calculation automatically?

是否有任何方法可以检索expires_in（30 天 => 2592000秒）的秒数或日期时间，以便我可以自动进行计算？

Here is how I managed to get it from the object:

这是我设法从对象中获取它的方法：

As Tim Lewis pointed me in the comments, there is a $token property, $user->createToken('API Access')is a Laravel\Passport\PersonalAccessTokenResultobject that contains 2 public properties : $accessToken (String)and $token (Laravel\Passport\Token). So I get the token with $objToken = $user->createToken('API Access');and calculate expiration time in seconds with $expiration = $objToken->token->expires_at->diffInSeconds(Carbon::now());. Here is the final code :

正如蒂姆刘易斯在评论中指出的那样，有一个 $token 属性，$user->createToken('API Access')是一个Laravel\Passport\PersonalAccessTokenResult包含 2 个公共属性的对象：$accessToken (String)和$token (Laravel\Passport\Token)。所以我得到了令牌$objToken = $user->createToken('API Access');并计算了以秒为单位的到期时间$expiration = $objToken->token->expires_at->diffInSeconds(Carbon::now());。这是最终的代码：

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);
}

But be careful if using these 2 lines in AuthServiceProvider boot() :

但是如果在 AuthServiceProvider boot() 中使用这两行要小心：

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

as it won't replace the expiration with Personal Access Token in Password Grant Type of Laravel 5.4 according to this Laravel Passport Issue.

因为它不会根据此Laravel Passport Issue 用Laravel 5.4 的密码授予类型中的个人访问令牌替换过期时间。
