# 文件系统
|
||
|
||
文件系统组件集成了 PHP 生态中大名鼎鼎的 League\Flysystem (这也是 Laravel 等诸多知名框架的底层库)。通过合理抽象，程序不必感知存储引擎究竟是本地硬盘还是云服务器，实现解耦。本组件对常用的云存储服务提供了协程化支持。
|
||
|
||
## 安装
|
||
|
||
```bash
|
||
# 首先执行
|
||
composer require hyperf/filesystem
|
||
# 使用阿里云 OSS 适配器时执行
|
||
composer require xxtime/flysystem-aliyun-oss
|
||
# 使用 S3 适配器时执行
|
||
composer require league/flysystem-aws-s3-v3
|
||
composer require hyperf/guzzle
|
||
# 使用七牛云（测试）适配器时执行
|
||
composer require overtrue/flysystem-qiniu
|
||
# 使用内存适配器时执行
|
||
composer require league/flysystem-memory
|
||
# 使用腾讯云 COS 适配器时执行
|
||
composer require overtrue/flysystem-cos
|
||
```
|
||
|
||
安装完成后，执行
|
||
|
||
```bash
|
||
php bin/hyperf.php vendor:publish hyperf/filesystem
|
||
```
|
||
|
||
就会生成 `config/autoload/file.php` 文件。在该文件中设置默认驱动，并配置对应驱动的 access key、access secret 等信息就可以使用了。
|
||
|
||
## 使用
|
||
|
||
通过 DI 注入 `League\Flysystem\Filesystem` 即可使用。
|
||
|
||
API 如下：
|
||
|
||
```php
|
||
<?php
|
||
|
||
declare(strict_types=1);
|
||
|
||
namespace App\Controller;
|
||
|
||
class IndexController extends AbstractController
|
||
{
|
||
public function example(\League\Flysystem\Filesystem $filesystem)
|
||
{
|
||
// Process Upload
|
||
$file = $this->request->file('upload');
|
||
$stream = fopen($file->getRealPath(), 'r+');
|
||
$filesystem->writeStream(
|
||
'uploads/'.$file->getClientFilename(),
|
||
$stream
|
||
);
|
||
fclose($stream);
|
||
|
||
// Write Files
|
||
$filesystem->write('path/to/file.txt', 'contents');
|
||
|
||
// Add local file
|
||
$stream = fopen('local/path/to/file.txt', 'r+');
|
||
$result = $filesystem->writeStream('path/to/file.txt', $stream);
|
||
if (is_resource($stream)) {
|
||
fclose($stream);
|
||
}
|
||
|
||
// Update Files
|
||
$filesystem->update('path/to/file.txt', 'new contents');
|
||
|
||
// Check if a file exists
|
||
$exists = $filesystem->has('path/to/file.txt');
|
||
|
||
// Read Files
|
||
$contents = $filesystem->read('path/to/file.txt');
|
||
|
||
// Delete Files
|
||
$filesystem->delete('path/to/file.txt');
|
||
|
||
// Rename Files
|
||
$filesystem->rename('filename.txt', 'newname.txt');
|
||
|
||
// Copy Files
|
||
$filesystem->copy('filename.txt', 'duplicate.txt');
|
||
|
||
// list the contents
|
||
$filesystem->listContents('path', false);
|
||
}
|
||
}
|
||
```
|
||
|
||
在某些时候，您会需要同时使用多种存储媒介。这时可以注入 `Hyperf\Filesystem\FilesystemFactory` 来动态选择使用哪种驱动。
|
||
|
||
```php
|
||
<?php
|
||
|
||
declare(strict_types=1);
|
||
|
||
namespace App\Controller;
|
||
|
||
class IndexController
|
||
{
|
||
public function example(\Hyperf\Filesystem\FilesystemFactory $factory)
|
||
{
|
||
$local = $factory->get('local');
|
||
// Write Files
|
||
$local->write('path/to/file.txt', 'contents');
|
||
|
||
$s3 = $factory->get('s3');
|
||
|
||
$s3->write('path/to/file.txt', 'contents');
|
||
}
|
||
}
|
||
```
|
||
|
||
### 配置静态资源
|
||
|
||
如果您希望通过 http 访问上传到本地的文件，请在 `config/autoload/server.php` 配置中增加以下配置。
|
||
|
||
```
|
||
return [
|
||
'settings' => [
|
||
...
|
||
// 将 public 替换为上传目录
|
||
'document_root' => BASE_PATH . '/public',
|
||
'enable_static_handler' => true,
|
||
],
|
||
];
|
||
|
||
```
|
||
|
||
## 注意事项
|
||
|
||
1. S3 存储请确认安装 `hyperf/guzzle` 组件以提供协程化支持。阿里云、七牛云、腾讯云云存储请[开启 Curl Hook](/zh-cn/coroutine?id=swoole-runtime-hook-level)来使用协程。因 Curl Hook 的参数支持性问题，请使用 Swoole 4.4.13 以上版本。
|
||
2. minIO, ceph radosgw 等私有对象存储方案均支持 S3 协议，可以使用 S3 适配器。
|
||
3. 使用 Local 驱动时，根目录是配置好的地址，而不是操作系统的根目录。例如，Local 驱动 `root` 设置为 `/var/www`, 则本地磁盘上的 `/var/www/public/file.txt` 通过 flysystem API 访问时应使用 `/public/file.txt` 或 `public/file.txt` 。
|
||
4. 以阿里云 OSS 为例，1 核 1 进程读操作性能对比：
|
||
|
||
```bash
|
||
ab -k -c 10 -n 1000 http://127.0.0.1:9501/
|
||
```
|
||
|
||
未开启 CURL HOOK：
|
||
|
||
```

||

||

|
||

|
||

|
||
```
|
||
|
||
开启 CURL HOOK 后：
|
||
|
||
