如何将幻灯片导出到Google幻灯片API中的HTML/PDF/DOC

Question

我正在使用Google Slides API创建PowerPoint演示文稿。额外必需的功能是 - 导出到PDF导出到HTML导出到文档/图像格式。

是否有幻灯片API给出的方法？

Answer 1

幻灯片API不直接支持导出，但是该功能可以从驱动器API中获得：

https://developers.google.com/drive/v3/reference/files/export

只需将幻灯片presentationId用作驱动器fileId。

假设您已经创建了幻灯片甲板，将Google幻灯片转换为PDF的过程将如下：

import apiclient.http as client_methods
# exporting the slide deck and specifying the desired final file type
data = drive_client.files().export(fileId=slide_id, mimeType='application/pdf').execute()
# request body to be send together the upload method
 body = {'name':file_name, 'mimeType':'application/pdf'}
# wrapping the binary (data) file with BytesIO class 
fh = client_methods.BytesIO(data)
# creating the Media Io upload class for the file (note that our original slide data is of binary type)
media_body = client_methods.MediaIoBaseUpload(fh, 
                                 mimetype='application/pdf')
# drive API v3 - .create | drive API v2 - .insert
pdf_file_id = drive_client.files().create(body=body, media_body=media_body).execute()['id']
# extra step: moving to desirable folder destination with the function method
def move_files(drive_client, id_, folder_id):
    file_ = drive_client.files().get(fileId=id_, fields='parents').execute()
    drive_client.files().update(fileId=id_, addParents=folder_id,
                           removeParents=file_['parents'][0],
                           fields='id,parents').execute()
# calling the move_files function.
# drive_client is authorized client, folder_id = desired destination directory (from url).
move_files(drive_client, pdf_file_id, folder_id)

希望这会有所帮助。

正如@codik所述，Google Slides API不直接支持导出，但您可以将Google Drive API用于导出。

这是我的解决方案。在导出之前，我也在侧面替换一些文本。

$substitutions = [
        'text_block_1' => "My First Text",
        'text_block_2' => "My Second Text"
    ];
// You can fond the google slide Id in the URL
$templateId = "Here comes the Google Slide Id";
$client = $certificationService->getGoogleClient();
$driveService = new Google_Service_Drive($client);
$slidesService = new Google_Service_Slides($client);

$copy = new Google_Service_Drive_DriveFile(array(
    'name' => 'Pdf Name' . ' presentation'
));
$driveResponse = $driveService->files->copy($templateId, $copy);
$fileId = $driveResponse->id;
// replaceable text should be covered with {{}} 
// example = {{text_block_1}}
$requests = [];
    foreach ($substitutions as $key => $value) {
        $requests[] = new Google_Service_Slides_Request(
            [
                'replaceAllText' => [
                    'containsText' => [
                        'text' => '{{'.$key.'}}',
                        'matchCase' => true
                    ],
                    'replaceText' => $value
                ]
            ]
        );
    }
$batchUpdateRequest = new Google_Service_Slides_BatchUpdatePresentationRequest(array(
        'requests' => $requests
    ));

$updateResponse = $slidesService->presentations->batchUpdate($fileId, $batchUpdateRequest);

// here you can specify the file type you want to export as
$response = $driveService->files->export($fileId, 'application/pdf', array('alt' => 'media'));

$content = $response->getBody()->getContents();
// delete the exported file from the Google Drive
$driveService->files->delete($fileId);

注意： - 为了使此代码工作，应与Google Service帐户电子邮件共享Google幻灯片。
