向Google storage上传文件

   //　Bucketを取得
    private static function getStorageBucket() {

        if (!isset(self::$bucket)) {
            putenv(Config::get('gcs.access_key'));
            $storage = new StorageClient();
            self::$bucket = $storage->bucket(Config::get('gcs.bucket'));
        }
    }

    //ファイルをstorageにアップロード
    private static function uploadToStorage($fileName) {
        self::getStorageBucket();
        // Bucket確認
        if (self::$bucket->exists()) {
            $fromPath = self::$current_jobno_path.DS.$fileName;
            if (file_exists($fromPath)) {
                $targePpath = "document_search".DS.self::$current_jobno.DS.$fileName;
                $options = [
                    'name' => $targePpath
                ];
                
                $handle = fopen($fromPath, 'r');
                $object = self::$bucket->upload(
                    $handle,
                    $options
                );
            } else {
                Log::error("ファイル(".$fromPath.")が不存在です。");
            }
            
        } else {
            Log::error('GCS BUCKET NOT EXIST.');
        }

    }

从Google storage下载文件

    public function download($from_file_path, $to_file_path) : String {
        $url = '';
        
        // manualファイル取得
        $object = $this->bucket->object($from_file_path);
        // 署名付きURL取得
        //         if ($object->exists()) {
        $stream  = $object->downloadToFile($to_file_path);
        //         }
        
        return $stream;
    }

获取Google storage中文件URL

    public function getUrl($file_path) : String {
        $url = '';
        
        // manualファイル取得
        $object = $this->bucket->object($file_path);
        // 署名付きURL取得
//         if ($object->exists()) {
            $url = $object->signedUrl(new DateTime('+60 minute'));
//         }
        
        return $url;
    }
