檔案系統

檔案系統元件集成了 PHP 生態中大名鼎鼎的 League\Flysystem (這也是 Laravel 等諸多知名框架的底層庫)。通過合理抽象，程式不必感知儲存引擎究竟是本地硬碟還是雲伺服器，實現解耦。本元件對常用的雲端儲存服務提供了協程化支援。

安裝

composer require hyperf/filesystem

League\Flysystem 元件 v1.0 和 v2.0 版本變動較大，所以需要根據不同的版本，安裝對應的介面卡

• 阿里與 OSS 介面卡

Flysystem v1.0 版本

composer require xxtime/flysystem-aliyun-oss

Flysystem v2.0 版本

composer require hyperf/flysystem-oss

• S3 介面卡

Flysystem v1.0 版本

composer require "league/flysystem-aws-s3-v3:^1.0"
composer require hyperf/guzzle

Flysystem v2.0 版本

composer require "league/flysystem-aws-s3-v3:^2.0"
composer require hyperf/guzzle

• 七牛介面卡

Flysystem v1.0 版本

composer require "overtrue/flysystem-qiniu:^1.0"

Flysystem v2.0 版本

composer require "overtrue/flysystem-qiniu:^2.0"

• 記憶體介面卡

Flysystem v1.0 版本

composer require "league/flysystem-memory:^1.0"

Flysystem v2.0 版本

composer require "league/flysystem-memory:^2.0"

• 騰訊雲 COS 介面卡

Flysystem v1.0 版本

flysystem-cos v2.0 版本已經不推薦使用了，請按照最新的文件修改為 3.0 版本

composer require "overtrue/flysystem-cos:^3.0"

Flysystem v2.0 版本

composer require "overtrue/flysystem-cos:^4.0"

安裝完成後，執行

php bin/hyperf.php vendor:publish hyperf/filesystem

就會生成 config/autoload/file.php 檔案。在該檔案中設定預設驅動，並配置對應驅動的 access key、access secret 等資訊就可以使用了。

使用

通過 DI 注入 League\Flysystem\Filesystem 即可使用。

API 如下：

以下示例為 Flysystem v1.0 版本，v2.0 版本請看官方文件

<?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);
    }
}

在某些時候，您會需要同時使用多種儲存媒介。這時可以注入 Hyperf\Filesystem\FilesystemFactory 來動態選擇使用哪種驅動。

<?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');
    }
}

配置靜態資源

如果您希望通過 http 訪問上傳到本地的檔案，請在 config/autoload/server.php 配置中增加以下配置。

return [
    'settings' => [
        ...
        // 將 public 替換為上傳目錄
        'document_root' => BASE_PATH . '/public',
        'enable_static_handler' => true,
    ],
];

注意事項

1. S3 儲存請確認安裝 hyperf/guzzle 元件以提供協程化支援。阿里雲、七牛雲、騰訊云云儲存請開啟 Curl Hook來使用協程。因 Curl Hook 的引數支援性問題，請使用 Swoole 4.4.13 以上版本。
2. minIO, ceph radosgw 等私有物件儲存方案均支援 S3 協議，可以使用 S3 介面卡。
3. 使用 Local 驅動時，根目錄是配置好的地址，而不是作業系統的根目錄。例如，Local 驅動 root 設定為 /var/www, 則本地磁碟上的 /var/www/public/file.txt 通過 flysystem API 訪問時應使用 /public/file.txt 或 public/file.txt 。
4. 以阿里雲 OSS 為例，1 核 1 程序讀操作效能對比：

ab -k -c 10 -n 1000 http://127.0.0.1:9501/

未開啟 CURL HOOK：

Concurrency Level:      10
Time taken for tests:   202.902 seconds
Complete requests:      1000
Failed requests:        0
Keep-Alive requests:    1000
Total transferred:      146000 bytes
HTML transferred:       5000 bytes
Requests per second:    4.93 [#/sec] (mean)
Time per request:       2029.016 [ms] (mean)
Time per request:       202.902 [ms] (mean, across all concurrent requests)
Transfer rate:          0.70 [Kbytes/sec] received

開啟 CURL HOOK 後：

Concurrency Level:      10
Time taken for tests:   9.252 seconds
Complete requests:      1000
Failed requests:        0
Keep-Alive requests:    1000

Time per request:       9.252 [ms] (mean, across all concurrent requests)
Transfer rate:          15.41 [Kbytes/sec] received
