检索记事和附件

以下示例展示了如何检索记事及其附件：

REST

使用附件下载的名称和 alt=media 网址参数调用 media.download()。alt=media 网址参数用于告知服务器正在请求下载内容。

如需获取附件的名称，您必须先检索记事。

注意 ：alt=media 网址参数是一个系统参数，适用于所有 Google REST API。如果您使用 Google Keep API 的客户端库，则无需明确设置此参数。

Java

/**
 * Gets and downloads the attachment of a note.
 *
 * @param note The note whose attachment will be downloaded.
 * @throws IOException
 */
private void getNoteAttachment(Note note) throws IOException {
  // First call is to get the attachment resources on the note.
  List<Attachment> attachments =
      keepService.notes().get(note.getName()).execute().getAttachments();

  if (!attachments.isEmpty()) {
    Attachment attachment = attachments.get(0);
    String mimeType = attachment.getMimeType().get(0);
    // A second call is required in order to download the attachment with the specified mimeType.
    OutputStream outputStream = new FileOutputStream("attachmentFile." + mimeType.split("/")[1]);
    keepService
        .media()
        .download(attachment.getName())
        .setMimeType(mimeType)
        .executeMediaAndDownloadTo(outputStream);
  }
}
