1、配置文件：\common\config\params-local.php，自媒体为来源
// 自媒体
'spider' => [
'asset' => [ // 资源
'image' => [ // 图片
'hostInfo' => 'http://localhost/channel-pub-api/storage/spider', // HOME URL
'baseUrl' => '/images', // BASE URL
'basePath' => 'E:/wwwroot/channel-pub-api/storage/spider/images', // BASE PATH
],
'video' => [ // 视频
'hostInfo' => 'http://localhost/channel-pub-api/storage/spider', // HOME URL
'baseUrl' => '/videos', // BASE URL
'basePath' => 'E:/wwwroot/channel-pub-api/storage/spider/videos', // BASE PATH
],
],
],
// 渠道发布接口
'channelPubApi' => [
'asset' => [ // 资源
'image' => [ // 图片
'basePath' => 'E:/wwwroot/channel-pub-api/storage/channel-pub-api/images', // BASE PATH
],
'video' => [ // 视频
'basePath' => 'E:/wwwroot/channel-pub-api/storage/channel-pub-api/videos', // BASE PATH
],
],
],
2、新建服务类，\common\services\AssetService.php，实现静态方法：copyAssets
<?php

*/ public static function copyAssets($source, $assets)
{
// 不是以来源的 HOME URL + BASE URL 开头的来源的资源文件
$notAbsoluteUrlStartKeys = [];
// 不存在的来源的资源文件
$notExistsKeys = [];
// 渠道发布的资源文件的相对路径
$channelPubApiAssetAbsolutePaths = [];
foreach ($assets as $key => $asset) {
// 检查来源的资源文件的绝对URL是否以来源的 HOME URL + BASE URL 开头
if (!StringHelper::startsWith($asset['absolute_url'], Yii::$app->params[$source]['asset'][$asset['type']]['hostInfo'] . Yii::$app->params[$source]['asset'][$asset['type']]['baseUrl'])) {
$notAbsoluteUrlStartKeys[] = $key;
} else {
// 获取来源的资源文件的绝对路径
$sourceAssetAbsolutePath = Yii::$app->params[$source]['asset'][$asset['type']]['basePath'] . str_replace(Yii::$app->params[$source]['asset'][$asset['type']]['hostInfo'] . Yii::$app->params[$source]['asset'][$asset['type']]['baseUrl'], '', $asset['absolute_url']);
// 检查来源的资源文件是否存在
if (!file_exists($sourceAssetAbsolutePath)) {
$notExistsKeys[] = $key;
}
}
}
if (!empty($notAbsoluteUrlStartKeys)) {
$notAbsoluteUrlStartKeys = implode(",", $notAbsoluteUrlStartKeys);
throw new UnprocessableEntityHttpException(Yii::t('common/error', Yii::t('common/error', Yii::t('common/error', '35003'), ['not_absolute_url_start_keys' => $notAbsoluteUrlStartKeys])), 35003);
}
if (!empty($notExistsKeys)) {
$notExistsKeys = implode(",", $notExistsKeys);
throw new NotFoundHttpException(Yii::t('common/error', Yii::t('common/error', Yii::t('common/error', '35004'), ['not_exists_keys' => $notExistsKeys])), 35004);
}
foreach ($assets as $key => $asset) {
// 获取来源的资源文件的绝对路径
$sourceAssetAbsolutePath = Yii::$app->params[$source]['asset'][$asset['type']]['basePath'] . str_replace(Yii::$app->params[$source]['asset'][$asset['type']]['hostInfo'] . Yii::$app->params[$source]['asset'][$asset['type']]['baseUrl'], '', $asset['absolute_url']);
// 获取来源的资源文件的路径信息
$pathInfo = pathinfo($sourceAssetAbsolutePath);
// 渠道发布的资源文件的相对路径
$directory = date('Y/m/d');
$channelPubApiAssetRelativePath = '/' . $directory . '/' . microtime(true) . '.' . mt_rand() . '.' . $pathInfo['extension'];
// 渠道发布的资源文件的绝对路径
$channelPubApiAssetAbsolutePath = Yii::$app->params['channelPubApi']['asset'][$asset['type']]['basePath'] . $channelPubApiAssetRelativePath;
// 创建目录
if (!FileHelper::createDirectory(Yii::$app->params['channelPubApi']['asset'][$asset['type']]['basePath'] . '/' . $directory)) {
throw new ServerErrorHttpException(Yii::t('common/error', Yii::t('common/error', Yii::t('common/error', '35005'), ['directory' => Yii::$app->params['channelPubApi']['asset'][$asset['type']]['basePath'] . '/' . $directory])), 35005);
}
// 复制来源的资源文件至渠道发布的资源目录
if (!copy($sourceAssetAbsolutePath, $channelPubApiAssetAbsolutePath)) {
throw new ServerErrorHttpException(Yii::t('common/error', Yii::t('common/error', Yii::t('common/error', '35006'), ['source_asset_absolute_path' => $sourceAssetAbsolutePath])), 35006);
}
$channelPubApiAssetAbsolutePaths[$key] = [
'type' => $asset['type'],
'relative_path' => $channelPubApiAssetRelativePath,
];
}
return $channelPubApiAssetAbsolutePaths;
}
}
3、引用服务类，\common\services\AssetService.php，调用静态方法：copyAssets
$assets = [
[
'type' => 'image',
'absolute_url' => 'http://localhost/channel-pub-api/storage/spider/images/1.png',
],
[
'type' => 'video',
'absolute_url' => 'http://localhost/channel-pub-api/storage/spider/videos/7月份北上广深等十大城市租金环比上涨 看东方 20180820 高清_高清.mp4',
],
];
$assetServiceResult = AssetService::copyAssets('spider', $assets);
print_r($assetServiceResult);
exit;
4、运行方法之后，打印出 $assetServiceResult
Array
(
[0] => Array
(
[type] => image
[relative_path] => /2018/09/21/1537495742.6172.473015079.png
)
[1] => Array
(
[type] => video
[relative_path] => /2018/09/21/1537495742.6251.651458618.mp4
)
)
5、查看复制后的目录与文件，符合预期，如图1
6、升级至开发环境(CentOS)后，复制文件成功，如图2
