python - 用于在没有 Google Driver UI 的情况下将大文件上传到 Google Drive 的 POST 消息

Question

我的理解是，要使用 API 版本 2 从我自己的应用程序将大文件上传到 Google 云端硬盘，我应该发送如下消息。不幸的是，我不知道如何使用 Python 为多部分消息实现这种格式。有没有人有示例 Python 代码可以让我朝着正确的方向前进？

谢谢， 克里斯

Google Drive API 的引用指南包含多种语言的代码片段，包括适用于所有 API 端点的 Python。

对于您的用例，drive.files.insert端点有答案:

from apiclient import errors
from apiclient.http import MediaFileUpload
# ...

def insert_file(service, title, description, parent_id, mime_type, filename):
  """Insert new file.

  Args:
    service: Drive API service instance.
    title: Title of the file to insert, including the extension.
    description: Description of the file to insert.
    parent_id: Parent folder's ID.
    mime_type: MIME type of the file to insert.
    filename: Filename of the file to insert.
  Returns:
    Inserted file metadata if successful, None otherwise.
  """
  media_body = MediaFileUpload(filename, mimetype=mime_type, resumable=True)
  body = {
    'title': title,
    'description': description,
    'mimeType': mime_type
  }
  # Set the parent folder.
  if parent_id:
    body['parents'] = [{'id': parent_id}]

  try:
    file = service.files().insert(
        body=body,
        media_body=media_body).execute()

    return file
  except errors.HttpError, error:
    print 'An error occured: %s' % error
    return None
