如何在流明中使用辅助功能? [英] How do I use helper functions in Lumen?

问题描述

    $credentials = app_path();

结果:

[Symfony \ Component \ Debug \ Exception \ FatalThrowableError]调用 未定义函数App \ LtClasses \ app_path()

[Symfony\Component\Debug\Exception\FatalThrowableError] Call to undefined function App\LtClasses\app_path()

但是它在此处被列为帮助器: https://laravel.com /docs/5.3/helpers#method-app-path

But it's listed as a helper here: https://laravel.com/docs/5.3/helpers#method-app-path

推荐答案

这些是Laravel文档，您在Lumen上没有相同的帮助程序，可以通过以下链接查看Lumen框架随附的帮助程序.

Those are the Laravel docs, you don't have the same helpers available on Lumen, you can have a look at the helpers that the Lumen framework comes with at

/vendor/laravel/lumen-framework/src/helpers.php

在这里实现您所需的解决方法可能是

Workarounds to achive what you need here could be

app()->path();

app('path');

base_path('app');
