流明的file_get_contents [英] file_get_contents with Lumen

问题描述

我将此代码放入一个函数中(php类):

I have this code into a function (php class) :

$theFile = '/test/test.xml'; // these are in the public folder
dd(file_get_contents($theFile));

如果我去mydomain.local/test/test.xml，我会得到有效的xml代码.

If I go to mydomain.local/test/test.xml, I get the working xml code.

但是使用file_get_contents时，出现此错误:

But with file_get_contents, I get this error :

file_get_contents(/test/test.xml): failed to open stream: No such file or directory

如何解决这个问题?

推荐答案

在Laravel中，Lumen没有您可能不熟悉的public_path()来轻松获取公共文件的路径.

Lumen doesn't have the public_path() that you might be familiar with in Laravel to easily grab the path to a public file.

重新实现它的最简单方法是将一个名为 irazasyed/larasupport 的软件包添加到您的该项目将添加各种缺少的帮助程序(包括public_path())，并添加流明缺少的供应商发布命令.

The simplest method for re-implementing it would be to add a package called irazasyed/larasupport to your project which adds various missing helpers (including public_path()) as well as adding the vendor publish command that is missing from Lumen.

或者，如果您不想添加第三方程序包，只需在应用程序目录中创建一个名为helpers.php的文件，然后在您的composer.json文件中，在自动加载"部分中添加以下内容并运行composer dump-autoload即可刷新自动加载器缓存:

Alternatively if you do not wish to add a third party package simply create a file in your app directory called helpers.php and then within your composer.json file add the following within the "autoload" part and run composer dump-autoload to refresh the autoloader cache:

"files": [
    "app/helpers.php"
],

然后在helpers.php中添加以下内容:

Then within helpers.php add the following content:

<?php
if (!function_exists('public_path')) {
   /**
    * Get the path to the public folder.
    *
    * @param  string $path
    * @return string
    */
    function public_path($path = '')
    {
        return env('PUBLIC_PATH', base_path('public')) . ($path ? '/' . $path : $path);
    }
}
