创建和管理演示文稿

本页介绍如何执行涉及 演示文稿,例如:

  • 创建演示文稿
  • 复制现有演示文稿

下文将详细介绍这些任务。

创建空白演示文稿

要创建演示文稿,请使用 create 方法 presentations 集合,如下所示 。

此示例创建了一个具有指定标题的空白演示文稿。

Apps 脚本

slides/api/Snippets.gs
/**
 * Creates a presentation
 * @returns {*} the created presentation
 */
function createPresentation() {
  try {
    const presentation = Slides.Presentations.create({
      title: title
    });
    console.log('Created presentation with ID: %s', presentation.presentationId);

    return presentation;
  } catch (err) {
    // TODO (Developer) - Handle exception
    console.log('Failed with error: %s', err.error);
  }
};

Go

slides/snippets/presentations.go
// Create a presentation and request a PresentationId.
p := &slides.Presentation{
	Title: "Title",
}
presentation, err := slidesService.Presentations.Create(p).Fields(
	"presentationId",
).Do()
if err != nil {
	log.Fatalf("Unable to create presentation. %v", err)
}
fmt.Printf("Created presentation with ID: %s", presentation.PresentationId)

  public static String createPresentation(String title) throws IOException {
        /* Load pre-authorized user credentials from the environment.
           TODO(developer) - See https://developers.google.com/identity for

    GoogleCredentials credentials = GoogleCredentials.getApplicationDefault()
        .createScoped(Collections.singleton(SlidesScopes.PRESENTATIONS));
    HttpRequestInitializer requestInitializer = new HttpCredentialsAdapter(
        credentials);

    // Create the slides API client
    Slides service = new Slides.Builder(new NetHttpTransport(),
        GsonFactory.getDefaultInstance(),
        requestInitializer)
        .setApplicationName("Slides samples")
        .build();

    // Creates a blank presentation with a specified title.
    Presentation presentation = new Presentation()
        .setTitle(title);
    presentation = service.presentations().create(presentation)
        .setFields("presentationId")
        .execute();
    // Prints the newly created presentation id.
    System.out.println("Created presentation with ID: " + presentation.getPresentationId());
    return presentation.getPresentationId();
  }
}

使用 Google 云端硬盘文件夹

您无法通过 Google Sheets API 直接在指定的云端硬盘文件夹中创建演示文稿。默认情况下,创建的演示文稿会保存到用户的云端硬盘根文件夹中。

不过,您也可以使用以下两种方法将文件保存到云端硬盘文件夹:

  • 创建演示文稿后,使用 Drive API 的 files.update 方法将其移至特定文件夹。要详细了解如何移动文件,请参阅在文件夹之间移动文件
  • 使用 Drive API 的 files.create 方法将空白演示文稿添加到文件夹中,并将 application/vnd.google-apps.presentation 指定为 mimeType。如需详细了解如何创建文件,请参阅在文件夹中创建文件

无论采用哪种方法,您都需要添加相应的 Drive API 范围来授权调用。

要在共享云端硬盘文件夹中移动或创建文件,请参阅实现共享云端硬盘支持

复制现有演示文稿

要复制演示文稿,请使用 Drive API files().copy 方法。

以下示例使用提供的 字符串。

Apps 脚本

slides/api/Snippets.gs
/**
 * create a presentation and copy it
 * @param {string} presentationId - ID of presentation to copy
 * @returns {*} the copy's presentation id
 */
function copyPresentation(presentationId) {
  const copyTitle = 'Copy Title';

  let copyFile = {
    title: copyTitle,
    parents: [{id: 'root'}]
  };
  try {
    copyFile = Drive.Files.copy(copyFile, presentationId);
    // (optional) copyFile.id can be returned directly
    const presentationCopyId = copyFile.id;

    return presentationCopyId;
  } catch (err) {
    // TODO (Developer) - Handle exception
    console.log('Failed with error: %s', err.error);
  }
};

Go
