转让使用Google驱动器API上传的文件的所有权 [英] Transfer ownership of file uploaded using Google drive API
本文介绍了转让使用Google驱动器API上传的文件的所有权的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
Google Drive API无法传输从API本身上传的文件的所有权。
根据API文档，需要使用PUT转让所有权。
当我使用它与所需的参数，它返回现有的权限。
不会与新所有者更新。
如果我使用POST&所需的参数抛出'远程服务器返回一个错误：（400）错误的请求。'
我能够更改没有通过上传的文件的所有权API。与我从API上传的文件一样。所有者不会改变。
它是一个错误还是我做错了什么？
-EDIT -
如果有人想要使用API&我可以通过gdocs创建文件。

解决方案 div>
它看起来像是在文章正文中指定 transferOwnership ，当它必须被指定为URL参数时。
The Google Drive API is not able to transfer ownership of a file which was uploaded from the API itself.
as per the API documentation, PUT needs to be used for transferring ownership. when I use it with the parameters required it returns existing permission back. doesn't update it with new owner.
if i use POST & the required parameters it throws 'The remote server returned an error: (400) Bad Request.'
I was able to change the ownership for the files that were NOT uploaded via API. the same which I use for the files which are uploaded from API. the owner doesn't change.
Is it a bug or I am doing something wrong?
-EDIT- if anyone wants details of file uploaded using API & file created via gdocs I can.

解决方案
It looks like you are specifying transferOwnership in the post body, when it must be specified as a URL parameter, as per the documentation.
