Question

我正在尝试使用python在google驱动器上创建文件夹结构。我检查了所有文档和所有类似的stackoverflow问题，但它不起作用。

我想要创建的文件夹结构类似于

2017 ----06 --------13 --------14

我没有设法在除root之外的任何其他位置创建文件夹。布局是平坦的，我不明白为什么。

# this method should create a directory tree, from a string like '2017/06/14'
def create_drive_folder(path):
    # this method should create a folder with the given parents
    # at first it is called with root as parent, for the 2017 folder
    # and when the 06 folder should be created it gets [root and the successfully created 2017 folder id]
    def create_drive_folder_level(filename, parents):
        dirs = drive.ListFile(
            {'q': "'{}' in parents and trashed=false and mimeType='application/vnd.google-apps.folder'".format(
                parents[-1]['id'])})

        try:
            # this will give me the parent folder, if it exists
            current = [x for x in list(dirs)[0] if x['title'] == filename][0]
        except HttpError:
            current = None
        except IndexError:
            current = None
        if not current:
            meta = {'title': filename, 'parents': [x['id'] for x in [parents[-1]],
                    'mimeType': 'application/vnd.google-apps.folder'}
            current = drive.CreateFile(meta)
            current.Upload({'convert': True})
            return current
        return current

    path = path.split('/')
    p = [dict(id='root')]
    for i in range(len(path)):
        p.append(create_drive_folder_level(path[i], p))

create_drive_folder('2017/06/14')

更新：

此代码生成的输出：

{'title': '2017', 'parents': ['root'], 'mimeType': 'application/vnd.google-apps.folder'}
GoogleDriveFile({'title': '2017', 'parents': [{'kind': 'drive#parentReference', 'id': '0AC4TRMtjeM-PUk9PVA', 'isRoot': True}], 'mimeType': 'application/vnd.google-apps.folder', 'kind': 'drive#file', 'id': '0By4TRMtjeM-PRjNPT0pXaFpxY2s', ...})

{'title': '06', 'parents': ['0By4TRMtjeM-PRjNPT0pXaFpxY2s'], 'mimeType': 'application/vnd.google-apps.folder'}
GoogleDriveFile({'title': '06', 'parents': [{'kind': 'drive#parentReference', 'id': '0AC4TRMtjeM-PUk9PVA', 'isRoot': True}], 'mimeType': 'application/vnd.google-apps.folder', 'kind': 'drive#file', 'id': '0By4TRMtjeM-PQUs0OWZ0VFlLTmM', ...})

{'title': '14', 'parents': ['0By4TRMtjeM-PQUs0OWZ0VFlLTmM'], 'mimeType': 'application/vnd.google-apps.folder'}
GoogleDriveFile({'title': '14', 'parents': [{'kind': 'drive#parentReference', 'id': '0AC4TRMtjeM-PUk9PVA', 'isRoot': True}], 'mimeType': 'application/vnd.google-apps.folder', 'kind': 'drive#file', 'id': '0By4TRMtjeM-PN2o4MVplZERiUzA', ...})

在我看来，在创建子目录时，我正在提供正确的ID。布局仍然平坦。为什么？

Answer 1

我实际上设法找到了解决方案。问题是，父母必须是口头禅，而不仅仅是字符串ID。所以而不是：

{'title': '06', 'parents': ['0By4TRMtjeM-PRjNPT0pXaFpxY2s']}

应该是：

{'title': '06', 'parents': [{'id': '0By4TRMtjeM-PRjNPT0pXaFpxY2s'}]}
