Laravel Storage Quick Reference Guide

Laravel's Storage facade is a convenient file handling helper that abstracts filesystem operations across multiple disks.

The following code snippets demonstrate typical tasks such as writing files, specifying disks, retrieving files, checking existence, downloading, generating URLs, handling temporary URLs, obtaining file size and modification time, managing visibility, appending and prepending content, copying, moving, uploading with custom filenames, and performing directory operations.

// 写入文件
Storage::put('avatars/1', $fileContents);
// 指定磁盘
Storage::disk('local')->put('file.txt', 'Contents');
Storage::get('file.jpg');
Storage::exists('file.jpg');
Storage::download('file.jpg',  $name,  $headers);
Storage::url('file.jpg');
Storage::temporaryUrl('file.jpg', now()->addMinutes(5));
Storage::size('file.jpg');
Storage::lastModified('file.jpg');
// 自动为文件名生成唯一的ID...
Storage::putFile('photos',  new  File('/path/to/photo'));
// 手动指定文件名...
Storage::putFileAs('photos', new File('/path/to/photo'), 'photo.jpg');
Storage::prepend('file.log', 'Prepended Text');
Storage::append('file.log', 'Appended Text');
Storage::copy('old/file.jpg', 'new/file.jpg');
Storage::move('old/file.jpg', 'new/file.jpg');
Storage::putFileAs('avatars', $request->file('avatar'), Auth::id());
// 「可见性」是对多个平台的文件权限的抽象
Storage::getVisibility('file.jpg');
Storage::setVisibility('file.jpg',  'public');
Storage::delete('file.jpg');
Storage::delete(['file.jpg',  'file2.jpg']);
// 获取目录下的所有的文件
Storage::files($directory);
Storage::allFiles($directory);
// 获取目录下的所有目录
Storage::directories($directory);
Storage::allDirectories($directory);
// 创建目录
Storage::makeDirectory($directory);
// 删除目录
Storage::deleteDirectory($directory);
