将纯文本文件上传到OneDrive后，驱动器项目大小错误

如何解决将纯文本文件上传到OneDrive后，驱动器项目大小错误

在uploading files to OneDrive for Business using the Graph API时，有时我会看到PUT请求后驱动器项目的大小错误。我知道OneDrive可能会即时修改Office文件，但我也看到纯文本文件也会发生这种情况。

在下面的示例中，我将字符串first version（13个字节）写入新的驱动器项目。

PUT https://graph.microsoft.com/v1.0/drives/b!e8-Jy2tSiUy2AJBZzvZxc3DIh8dRoG9DrM6MEcF_oxinj1yhH9A8RYDHeCfkxipc/items/root:/onedrive-public-kuvgpshldglnfidf.
txt:/content

不要紧，但我将Content-Type标头设置为application/octet-stream。 Graph API返回状态码201（如预期）和响应：

请注意驱动器项目的大小是26，而不是预期的13。如果我使用GET请求获取驱动器项目，则驱动器项目大小仍为26。如果我遵循下载URL，虽然可以得到正确的Content-Length标头：

$ curl -v -H "Authorization: bearer $TOKEN" $DOWNLOADURL
...
< HTTP/2 200 
< cache-control: private
< content-length: 13
< content-type: text/plain
...
first version

是否可以直接获得正确的驱动器项目大小，而不必遵循下载URL时检查Content-Length标头？

解决方法

在OneDrive中上传文件后，上传后，它将在Office文档中添加其他元数据（尽管不是文件类型）。我记得与此有关的一个话题，正在讨论-link。
