python - 使用带有 ocr 的 gdata docs python v3.0 上传 pdf 文件

Question

我有以下用于将 pdf 文件上传到 google docs 的实现(取自 gdata API 示例):

def UploadResourceSample():
  """Upload a document, and convert to Google Docs."""
  client = CreateClient()
  doc = gdata.docs.data.Resource(type='document', title='My Sample Doc')

  # This is a convenient MS Word doc that we know exists
  path = _GetDataFilePath('test.0.doc')
  print 'Selected file at: %s' % path

  # Create a MediaSource, pointing to the file
  media = gdata.data.MediaSource()
  media.SetFileHandle(path, 'application/msword')

  # Pass the MediaSource when creating the new Resource
  doc = client.CreateResource(doc, media=media)
  print 'Created, and uploaded:', doc.title.text, doc.resource_id.text

现在我想对上传的文件进行OCR文字识别。但我不确定如何在 gdata docs python API 中启用 OCR 识别。所以我的问题是:有没有办法在 pdf 文件上使用 gdata python v3.0 API 启用 OCR 识别？

我已经成功地使用以下代码对我的 pdf 文档进行了 OCR:

def UploadResourceSample(filename, filepath, fullpath):
  """Upload a document, and convert to Google Docs."""
  client = CreateClient()
  doc = gdata.docs.data.Resource(type='document', title=filename)

  path = fullpath
  print 'Selected file at: %s' % path

  # Create a MediaSource, pointing to the file
  media = gdata.data.MediaSource()
  media.SetFileHandle(path, 'application/pdf')

  # Pass the MediaSource when creating the new Resource
  create_uri = gdata.docs.client.RESOURCE_UPLOAD_URI + '?ocr=true&ocr-language=de'
  doc = client.CreateResource(doc, create_uri=create_uri, media=media)
  print 'Created, and uploaded:', doc.title.text, doc.resource_id.text
