使用Graph API 将文件上传到 OneDrive for Business时，我有时会看到驱动器项目在PUT请求后的大小错误。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。

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

不要认为这很重要，但我将Content-Type标题设置为application/octet-stream. Graph API 返回状态码 201（如预期）和响应：

 "@odata.context": "https:\/\/graph.microsoft.com\/v1.0\/$metadata#drives('b%21e8-Jy2tSiUy2AJBZzvZxc3DIh8dRoG9DrM6MEcF_oxinj1yhH9A8RYDHeCfkxipc')\/items\/$entity",

请注意驱动器项目大小是 26 而不是预期的 13。GET如果我使用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，我会得到正确的Content-Length标题：

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

跟随下载 URL 时是否可以直接获得正确的驱动器项目大小而无需检查Content-Length标题？

Once you upload the file in the OneDrive, then it will add additional metadata to Office documents after you upload (not the file types though). I remember a related thread on this, discussing about this - link.
