如何在 Laravel 中访问公共目录?

要从公共目录中获取文件列表，您可以使用 File Facade 类。要使用它，您需要使用以下语句包含 File 类 -

use Illuminate\Support\Facades\File;

假设我们在公共文件夹中有以下文件 -

示例 1

以下程序尝试从 public_folder 中检索所有图像 -

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Support\Facades\Storage;
class UserController extends Controller {
   public function index() {
      $images = \File::allFiles(public_path('images'));
      print_r($images);
   }
}

输出

上面的输出如下 −

Array (
   [0] => Symfony\Component\Finder\SplFileInfo Object (
      [relativePath:Symfony\Component\Finder\SplFileInfo:private] =>
      [relativePathname:Symfony\Component\Finder\SplFileInfo:private] => flower.jpg
      [pathName:SplFileInfo:private] => C:\xampp\htdocs\laraveltest\public\images\flower.jpg
      [fileName:SplFileInfo:private] => flower.jpg
   )
)

示例 2

要从 public_folder 获取所有 CSS 文件，您只需将字符串"css"传递给 public_path() 方法。

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
class UserController extends Controller {
   public function index() {
      $css_files = \File::allFiles(public_path('css'));
      print_r($css_files);
   }
}

输出

上述代码的输出是 −

Array (
   [0] => Symfony\Component\Finder\SplFileInfo Object (
      [relativePath:Symfony\Component\Finder\SplFileInfo:private] =>
      [relativePathname:Symfony\Component\Finder\SplFileInfo:private] => test.css
      [pathName:SplFileInfo:private] => C:\xampp\htdocs\laraveltest\public\css\test.css
      [fileName:SplFileInfo:private] => test.css
   )
)

示例 3

要从公共文件夹中获取所有文件，代码如下 -

$path = public_path();
$files = File::allFiles($path);

$files 变量是一个数组，其中包含 public/ 文件夹中存在的所有文件的详细信息。

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\File;
class UserController extends Controller {
   public function index() {
      $path = public_path();
      $files = File::allFiles($path);
      print_r($files);
   }
}

输出

上述代码的输出是 −

Array(
   [0] => Symfony\Component\Finder\SplFileInfo Object(
      [relativePath:Symfony\Component\Finder\SplFileInfo:private] => css
      [relativePathname:Symfony\Component\Finder\SplFileInfo:private] => css\test.css
      [pathName:SplFileInfo:private] => C:\xampp\htdocs\laraveltest\public\css\test.css
      [fileName:SplFileInfo:private] => test.css
   )
   
   [1] => Symfony\Component\Finder\SplFileInfo Object(
      [relativePath:Symfony\Component\Finder\SplFileInfo:private] =>
      [relativePathname:Symfony\Component\Finder\SplFileInfo:private] => favicon.ico
      [pathName:SplFileInfo:private] => C:\xampp\htdocs\laraveltest\public\favicon.ico
      [fileName:SplFileInfo:private] => favicon.ico
   )
  
  [2] => Symfony\Component\Finder\SplFileInfo Object(
      [relativePath:Symfony\Component\Finder\SplFileInfo:private] => images
      [relativePathname:Symfony\Component\Finder\SplFileInfo:private] => images\flower.jpg
      [pathName:SplFileInfo:private] => C:\xampp\htdocs\laraveltest\public\images\flower.jpg
      [fileName:SplFileInfo:private] => flower.jpg
   )

   [3] => Symfony\Component\Finder\SplFileInfo Object(
      [relativePath:Symfony\Component\Finder\SplFileInfo:private] =>
      [relativePathname:Symfony\Component\Finder\SplFileInfo:private] => index.php
      [pathName:SplFileInfo:private] => C:\xampp\htdocs\laraveltest\public\index.php
      [fileName:SplFileInfo:private] => index.php
   )

   [4] => Symfony\Component\Finder\SplFileInfo Object(
      [relativePath:Symfony\Component\Finder\SplFileInfo:private] =>
      [relativePathname:Symfony\Component\Finder\SplFileInfo:private] => robots.txt
      [pathName:SplFileInfo:private] => C:\xampp\htdocs\laraveltest\public\robots.txt
      [fileName:SplFileInfo:private] => robots.txt
   )
)

示例 4

您可以使用 scandir() 获取 public/images 文件夹中的所有文件。具体操作如下 −

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class UserController extends Controller {
   public function index() {
      $path = public_path('images');
      $files = scandir($path);
      print_r($files);
   }
}

输出

上述代码的输出是 −

Array
(
   [0] => .
   [1] => ..
   [2] => flower.jpg
)
