我正在尝试将PDF转换为任何允许的格式,但在上传pdf文件后,响应不会对exportLinks进行内容处理。
我已经尝试了很多方法来管理获取exportLinks。可以上载其他文档格式并成功导出。我使用了来自developers.google.com的代码。
media_body = MediaFileUpload(filename, mimetype=mime_type, resumable=False)
body = {'title': title,
'description': description,
'mimeType': mime_type,
}
# Set the parent folder.
if parent_id:
body['parents'] = [{'id': parent_id}]
try:
request = service.files().insert(body=body, media_body=media_body)
#request.uri = "%s&convert=true&ocr=true" % request.uri
#request.uri = "%s&convert=true" % request.uri
request.uri = "https://www.googleapis.com/upload/drive/v2/files?uploadType=multipart&alt=json&convert=true"
logger.debug("Request: %s", request.uri)
file_obj = request.execute()
# Uncomment the following line to print the File ID
# print 'File ID: %s' % file_obj['id']
import json
logger.debug('Get file result: %s' % json.dumps(file_obj, indent=4))
return file_obj
...
export_links = source_file.get('exportLinks')
if not export_links:
logger.debug('Warning: exportLinks does not exist')
为什么PDF上传的响应中没有exportLinks?
请Google团队同意PDF可以通过Drive API上传和导出。

[UPD] 这是Httplib2的请求转储。我看到查询是根据手册正确设置的。

答案 0 :(得分:4)
遗憾的是,Google云端硬盘不通过Google Drive API为PDF文件提供转换功能。
只有Google原生文档(Google文档/表格/幻灯片/图纸)exportLinks
允许以多种导出格式下载Google文档。所有其他文件 - 基本上是常规文件,如PDF,图像等...... - 有一个downloadUrl
,它允许您以原始格式下载文件。
