在 Yii 2.0 中实现：资源服务(复制来源的资源文件至渠道发布的存储目录，返回相对路径)
1、配置文件：\common\config\params-local.php，自媒体为来源
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | // 自媒体'spider' => [ 'asset' => [ // 资源 'image' => [ // 图片 'baseUrl' => '/images', // BASE URL 'basePath' => 'E:/wwwroot/channel-pub-api/storage/spider/images', // BASE PATH ], 'video' => [ // 视频 '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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 | <?php/** * Created by PhpStorm. * User: WangQiang * Date: 2018/09/20 * Time: 14:04 */namespace common\services;use Yii;use yii\base\Model;use common\logics\ChannelAppSource;use yii\db\ActiveRecordInterface;use yii\helpers\StringHelper;use yii\helpers\FileHelper;use yii\web\NotFoundHttpException;use yii\web\UnprocessableEntityHttpException;use yii\web\ServerErrorHttpException;use yii\web\HttpException;/** * 资源服务 * * @author Qiang Wang <shuijingwanwq@163.com> * @since 1.0 */class AssetService extends Service{ /** * 复制来源的资源文件至渠道发布的资源目录，返回相对路径 * @param string $source 来源 * 格式如下：spider * @param array $assets 来源的资源文件的绝对URL * 格式如下： * [ * [ * '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', * ], * ] * * @return array $channelPubApiAssetAbsolutePaths 渠道发布的资源文件的相对路径 * 格式如下： * [ * [ * 'type' => 'image', * 'relative_path' => '/2018/09/20/1537439889.2333.1441541478.png', * ], * [ * 'type' => 'video', * 'relative_path' => '/2018/09/20/1537439889.2403.62871268.mp4', * ], * ] * * @throws UnprocessableEntityHttpException 如果来源的资源文件不是以来源的 HOME URL + BASE URL 开头，将抛出 422 HTTP 异常 * @throws NotFoundHttpException 如果来源的资源文件不存在，将抛出 404 HTTP 异常 * @throws ServerErrorHttpException 如果创建目录失败，将抛出 500 HTTP 异常 * @throws ServerErrorHttpException 如果复制来源的资源文件至渠道发布的资源目录失败，将抛出 500 HTTP 异常 * @throws \yii\base\Exception if the directory could not be created (i.e. php error due to parallel changes) */ public static function copyAssets($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'], '', $asset['absolute_url']); // 检查来源的资源文件是否存在 if (!file_exists($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'] .

'/' . 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'] .

3、引用服务类，\common\services\AssetService.php，调用静态方法：copyAssets
1 2 3 4 5 6 7 8 9 10 11 12 13 | $assets = [ [ 'type' => 'image', ], [ 'type' => 'video', 'absolute_url' => 'http://localhost/channel-pub-api/storage/spider/videos/7月份北上广深等十大城市租金环比上涨 看东方 20180820 高清_高清.mp4', ],];$assetServiceResult = AssetService::copyAssets('spider', $assets);print_r($assetServiceResult);exit; |
4、运行方法之后，打印出 $assetServiceResult
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | 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
