阿里云对象存储(OSS)基于flysystem Yii2 扩展
本扩展的文件管理系统,采用 Flysystem,通过 Yii2扩展creocoder/yii2-flysystem将其集成到Yii2框架中。
通过阿里云OSS的适配器OssAdapter,将两者结合在一起。
目的:标准化文件管理的接口,方便迁移到其他云平台。
The preferred way to install this extension is through composer.
执行安装命令
$ composer require bestyii/yii2-aliyun-oss
或添加以下
"bestyii/yii2-aliyun-oss": "*"
到 composer.json
文件的 require
部分.
配置Yii的 components
如下:
return [
//...
'components' => [
//...
'fs' => [
'class' => 'bestyii\aliyunoss\Filesystem',
'accessId' => OSS_ACCESS_ID,
'accessSecret' => OSS_ACCESS_SECRET,
'region' => OSS_REGION,
'bucket' => OSS_BUCKET,
'endpoint' => OSS_ENDPOINT,
// 'timeout' => 3600,
// 'connectTimeout' => 10,
// 'isCName' => false,
// 'token' => '',
],
],
];
To write file
Yii::$app->fs->write('filename.ext', 'contents');
To write file using stream contents
$stream = fopen('/path/to/somefile.ext', 'r+');
Yii::$app->fs->writeStream('filename.ext', $stream);
To update file
Yii::$app->fs->update('filename.ext', 'contents');
To update file using stream contents
$stream = fopen('/path/to/somefile.ext', 'r+');
Yii::$app->fs->updateStream('filename.ext', $stream);
To write or update file
Yii::$app->fs->put('filename.ext', 'contents');
To write or update file using stream contents
$stream = fopen('/path/to/somefile.ext', 'r+');
Yii::$app->fs->putStream('filename.ext', $stream);
To read file
$contents = Yii::$app->fs->read('filename.ext');
To retrieve a read-stream
$stream = Yii::$app->fs->readStream('filename.ext');
$contents = stream_get_contents($stream);
fclose($stream);
To check if a file exists
$exists = Yii::$app->fs->has('filename.ext');
To delete file
Yii::$app->fs->delete('filename.ext');
To read and delete file
$contents = Yii::$app->fs->readAndDelete('filename.ext');
To rename file
Yii::$app->fs->rename('filename.ext', 'newname.ext');
To get file mimetype
$mimetype = Yii::$app->fs->getMimetype('filename.ext');
To get file timestamp
$timestamp = Yii::$app->fs->getTimestamp('filename.ext');
To get file size
$timestamp = Yii::$app->fs->getSize('filename.ext');
To create directory
Yii::$app->fs->createDir('path/to/directory');
Directories are also made implicitly when writing to a deeper path
Yii::$app->fs->write('path/to/filename.ext');
To delete directory
Yii::$app->fs->deleteDir('path/to/filename.ext');
Visibility is the abstraction of file permissions across multiple platforms. Visibility can be either public or private.
use League\Flysystem\AdapterInterface;
Yii::$app->fs->write('filename.ext', 'contents', [
'visibility' => AdapterInterface::VISIBILITY_PRIVATE
]);
You can also change and check visibility of existing files
use League\Flysystem\AdapterInterface;
if (Yii::$app->fs->getVisibility('filename.ext') === AdapterInterface::VISIBILITY_PRIVATE) {
Yii::$app->fs->setVisibility('filename.ext', AdapterInterface::VISIBILITY_PUBLIC);
}
To list contents
$contents = Yii::$app->fs->listContents();
foreach ($contents as $object) {
echo $object['basename']
. ' is located at' . $object['path']
. ' and is a ' . $object['type'];
}
By default Flysystem lists the top directory non-recursively. You can supply a directory name and recursive boolean to get more precise results
$contents = Yii::$app->fs->listContents('path/to/directory', true);
To list paths
$paths = Yii::$app->fs->listPaths();
foreach ($paths as $path) {
echo $path;
}
To list with ensured presence of specific metadata
$listing = Yii::$app->fs->listWith(
['mimetype', 'size', 'timestamp'],
'optional/path/to/directory',
true
);
foreach ($listing as $object) {
echo $object['path'] . ' has mimetype: ' . $object['mimetype'];
}
To get file info with explicit metadata
$info = Yii::$app->fs->getWithMetadata('path/to/filename.ext', ['timestamp', 'mimetype']);
echo $info['mimetype'];
echo $info['timestamp'];
