JWT 错误Unresolvable dependency resolving

Question

调用代码
$token = JWTAuth::attempt($credentials)
会报错。

我的Lumen版本是5.5，报错的原因是cache和auth没有开启，在Lumen默认是关闭的。

打开bootstrap/app.php，在你的jwt配置下开启cache和auth，添加如下代码：

$app->alias('cache', 'Illuminate\Cache\CacheManager');
$app->singleton(Illuminate\Auth\AuthManager::class, function ($app) {
    return $app->make('auth');
});

这样就可以解决了，happy coding！！
