Laravel 5.8类Exception中的无法解析的依赖项解析[Parameter＃0 [<optional> $ message]]

时间：2019-09-22 04:35:59

标签： php exception laravel-5.8

我已经用CustomInvalidInputException创建了php artisan make:exception CustomInvalidInputException。

在我的CustomerRepository.php文件中，我正在举起新创建的CustomInvalidInputException。

但是我遇到了如下异常。任何帮助表示赞赏。

答案 0 :(得分：0)

我只是在尝试类似问题时遇到类似的问题：

return app(ArrayIterator::class, ['array' => $this->content]);

相同错误，可选参数上的BindingResolutionException。因此，我直接尝试了反射，只是为了进行实验：

$class = new \ReflectionClass(ArrayIterator::class);
$method = $class->getMethod('__construct');
$parameters = $method->getParameters();
/** @var \ReflectionParameter $parameter */
$parameter = $parameters[1];
dd($parameter->getDefaultValue());

由此导致的错误是Google能够提供更多线索的原因：

ReflectionException: Cannot determine default value for internal functions

它看起来像floorKey()。与Illuminate\Container\Container::resolvePrimitive()一样，该线程中的推荐解决方案是首先检查$parameter->isDefaultValueAvailable()。显然，对于默认值对于Reflection不可见的参数，它返回false，这不一定意味着它们不存在。

这意味着您和我将不得不new来建立内部类，或显式地重新声明默认值。所以...如果其他人可以进来证明我做错了，我会很高兴，因为这两种解决方案都不是最佳选择。
