php pdf转图片列表

使用 composer require spatie/pdf-to-image
服务器需要安装ImageMagick，并且将/etc/ImageMagick-6/policy.xml
找到pdf这一行，注释掉或者增加读、写、编译
 <policy domain="coder" rights="read|write|decode" pattern="PDF" />


public function pdfToImage(RequestInterface $request): ResponseInterface
{
    $fileUrl = $request->input('fileUrl');
    $client = new Client();
    $ossclient = new OssClient(env('accessId'), env('accessSecret'), env('endpoint'));

    // 下载PDF文件内容
    $response = $client->get($fileUrl);
    $pdfContent = (string)$response->getBody();

    // 获取存储路径或创建一个Filesystem实例（假设你使用了Flysystem适配器）
    $fileSystem = new Filesystem();
    $fileName = md5($fileUrl);
    $check = BookshelfPdf::where('uuid', $fileName)->pluck('path');
    if (count($check) == 0) {
        $savePath = "public/pdf/{$fileName}.pdf"; // 替换为实际保存PDF的路径和文件名

        // 将PDF内容写入本地文件
        $fileSystem->append($savePath, $pdfContent);
        $pdf = new Pdf($savePath);
        $imageList = [];
        foreach (range(1, $pdf->getNumberOfPages()) as $pageNumber) {
            $imagePath = "public/images/page_$pageNumber.jpg";
            $pdf->setPage($pageNumber)->saveImage($imagePath);
            // 将生成的图片路径添加到图片列表
            $ossclient->uploadFile(env('bucket'), "upload/pdfToImage/{$fileName}_page_$pageNumber.jpg", $imagePath);
            $imageList[] = env('domain') . "/upload/pdfToImage/{$fileName}_page_$pageNumber.jpg";
            $fileSystem->delete($imagePath);
            BookshelfPdf::create([
                'uuid' => $fileName,
                'file_url' => $fileUrl,
                'path' => env('domain') . "/upload/pdfToImage/{$fileName}_page_$pageNumber.jpg"
            ]);
        }
        $fileSystem->delete($savePath);
    } else {
        $imageList = $check;
    }
    return $this->response->success("查询成功",$imageList);
