在Python中從緩衝區插入Google Drive API文件

Question

我想弄清楚如何在files().insert()方法中指定media_body方法來自緩衝區（甚至是文件類對象），而不是保存臨時文件，然後使用MediaFileUpload插入Google Drive，然後，然後刪除臨時文件。

有沒有人有這個運氣，可以指出我在正確的方向嗎？

Answer 1

我已經使用AppEngine上這個代碼從緩衝上傳：

def insert_file(service, title, description, parent_id, mime_type, filebody): 
     """Insert new file and deletes old file, if with same title. 

     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. 
     filebody: string, Bytes of body content. 
     filename: Filename of the file to insert. 
     Returns: 
     Inserted file metadata if successful, None otherwise. 
     """ 

     urlfetch.set_default_fetch_deadline(45) 

     # check if file is already there 
     param = {} 
     param['q'] = "title = '"+title+"'" 
     filelist = service.files().list(**param).execute() 
     if filelist: 
      for f in filelist['items']: 
       file_id = f['id'] 
       # logging.info("file: %s - %s" % (f['title'], file_id)) 
       # here we could delete the file, skip trash 
       service.files().delete(fileId=file_id).execute() 

     media_body = MediaInMemoryUpload(filebody, mime_type) 
     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: 
      logging.info('An error occured: %s' % error) 
     return None
