扩展包要求

  • PHP >= 7.0

安装命令

$ composer require "iidestiny/flysystem-oss" -vvv

使用

use League\Flysystem\Filesystem;
use Iidestiny\Flysystem\Oss\OssAdapter;
use Iidestiny\Flysystem\Oss\Plugins\FileUrl;

$prefix = ''; // 前缀,非必填
$accessKeyId = 'xxxxxx';
$accessKeySecret = 'xxxxxx';
$endpoint= 'oss.iidestiny.com'; // ssl:https://iidestiny.com
$bucket = 'bucket';
$isCName = true; // 如果 isCname 为 false,endpoint 应配置 oss 提供的域名如:`oss-cn-beijing.aliyuncs.com`,cname 或 cdn 请自行到阿里 oss 后台配置并绑定 bucket

$adapter = new OssAdapter($accessKeyId, $accessKeySecret, $endpoint, $bucket, $isCName, $prefix);

$flysystem = new Filesystem($adapter);

常用方法

bool $flysystem->write('file.md', 'contents');

bool $flysystem->write('file.md', 'http://httpbin.org/robots.txt', ['options' => ['xxxxx' => 'application/redirect302']]);

bool $flysystem->writeStream('file.md', fopen('path/to/your/local/file.jpg', 'r'));

bool $flysystem->update('file.md', 'new contents');

bool $flysystem->updateStream('file.md', fopen('path/to/your/local/file.jpg', 'r'));

bool $flysystem->rename('foo.md', 'bar.md');

bool $flysystem->copy('foo.md', 'foo2.md');

bool $flysystem->delete('file.md');

bool $flysystem->has('file.md');

string|false $flysystem->read('file.md');

array $flysystem->listContents();

array $flysystem->getMetadata('file.md');

int $flysystem->getSize('file.md');

string $flysystem->getAdapter()->getUrl('file.md');

string $flysystem->getMimetype('file.md');

int $flysystem->getTimestamp('file.md');

插件扩展

use Iidestiny\Flysystem\Oss\Plugins\FileUrl;
use Iidestiny\Flysystem\Oss\Plugins\SignUrl;
use Iidestiny\Flysystem\Oss\Plugins\TemporaryUrl;
use Iidestiny\Flysystem\Oss\Plugins\SetBucket;

// 获取 oss 资源访问链接
$flysystem->addPlugin(new FileUrl());

string $flysystem->getUrl('file.md');

// url 访问有效期 & 图片处理「$timeout 为多少秒过期」
$flysystem->addPlugin(new SignUrl());

 string $flysystem->signUrl('file.md', $timeout, ['x-oss-process' => 'image/circle,r_100']);

 // url 访问有效期「$expiration 为未来时间 2019-05-05 17:50:32」
$flysystem->addPlugin(new TemporaryUrl());

string $flysystem->getTemporaryUrl('file.md', $expiration);

// 多个bucket切换
$flysystem->addPlugin(new SetBucket());
$flysystem->bucket('test')->has('file.md');

获取官方完整 OSS 处理能力

阿里官方 SDK 可能处理了更多的事情,如果你想获取完整的功能可通过此插件获取, 然后你将拥有完整的 oss 处理能力

use Iidestiny\Flysystem\Oss\Plugins\Kernel;

$flysystem->addPlugin(new Kernel());
$kernel = $flysystem->kernel();

// 例如:防盗链功能
$refererConfig = new RefererConfig();
// 设置允许空Referer。
$refererConfig->setAllowEmptyReferer(true);
// 添加Referer白名单。Referer参数支持通配符星号(*)和问号(?)。
$refererConfig->addReferer("www.aliiyun.com");
$refererConfig->addReferer("www.aliiyuncs.com");

$kernel->putBucketReferer($bucket, $refererConfig);

前端 web 直传配置

oss 直传有三种方式,当前扩展包使用的是最完整的 服务端签名直传并设置上传回调 方式,扩展包只生成前端页面上传所需的签名参数,前端上传实现可参考 官方文档中的实例 或自行搜索

use Iidestiny\Flysystem\Oss\Plugins\SignatureConfig;

$flysystem->addPlugin(new SignatureConfig());

/**
 * 1. 前缀如:'images/'
 * 2. 回调服务器 url
 * 3. 回调自定义参数,oss 回传应用服务器时会带上
 * 4. 当前直传配置链接有效期
 * 5. 文件大小限制
 * 6. 回调系统参数, 默认值: Iidestiny\Flysystem\Oss\OssAdapter::SYSTEM_FIELD
 */
object $flysystem->signatureConfig($prefix = '/', $callBackUrl = '', $customData = [], $expire = 30, $maxSize = 1024 * 1024 * 2, $systemData = ['etag' => '${etag}', 'filename' => '${object}']);

直传回调验签

当设置了直传回调后,可以通过验签插件,验证并获取 oss 传回的数据 文档

注意事项:

  • 如果没有 Authorization 头信息导致验签失败需要先在 apache 或者 nginx 中设置 rewrite
  • 以 apache 为例,修改 httpd.conf 在 DirectoryIndex index.php 这行下面增加「RewriteEngine On」「RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization},last]」
use Iidestiny\Flysystem\Oss\Plugins\Verify;

$flysystem->addPlugin(new Verify());

list($verify, $data) = $flysystem->verify();
// [$verify, $data] = $flysystem->verify(); // php 7.1 +

if (!$verify) {
    // 验证失败处理,此时 $data 为验签失败提示信息
}

// 注意一定要返回 json 格式的字符串,因为 oss 服务器只接收 json 格式,否则给前端报 CallbackFailed
header("Content-Type: application/json");
echo  json_encode($data);

直传回调验签后返回给前端的数据「包括自定义参数」,例如

{
    "bucket": "your-bucket",
    "etag": "D8E8FCA2DC0F896FD7CB4CB0031BA249",
    "filename": "user/15854050909488182.png",
    "size": "56039",
    "mimeType": "image/png",
    "height": "473",
    "width": "470",
    "format": "png",
    "custom_name": "zhangsan",
    "custom_age": "24"
}

这其实要看你回调通知方法具体怎么返回,如果直接按照文档给的方法返回是这个样子
