0x00 Introduction
Microsoft OneDrive has long been a indispensable cloud service for me to store PPTs, PDFs, etc. Its user experience are marvelous, the sync, upload and download speed are satisfying, but what bothers me is that it takes me a long time to fully load a OneDrive file share page, as a result, I seldom use OneDrive to share files with my friends.
0x01 Methods
It is quite simple to obtain direct download link for personal OneDrive link like
1 | https://1drv.ms/u/s!AnN4R6WWGczehw51hTeeCjrbL_4O |
Just replace the “1drv.ms” with “1drv.ws“, the new link is what we want.In this case, the direct download link should be:
1 | https://1drv.ws/u/s!AnN4R6WWGczehw51hTeeCjrbL_4O. |
As for personal OneDrive link after redirection like
1 | https://onedrive.live.com/redir.aspx?resid=DECC1996A5477873!723&authkey=!AqWkl_GohQTI94Y |
We need to obtain two credentials in the query string, which is “resid” and “authkey “, in this case, they are “DECC1996A5477873!723” and “!AqWkl_GohQTI94Y” respectively. After gathering the credentials, the direct link can be generated like following form:
1 | http://storage.live.com/items/{resid}?authkey={authkey} |
In this case, the direct download link should be:
1 | http://storage.live.com/items/DECC1996A5477873!723?authkey=!AqWkl_GohQTI94Y |
Then the Office 365 OneDrive link like:
1 | https://xxx-my.sharepoint.com/:b:/g/personal/xx_xxx_onmicrosoft_com/blah-blah |
We also need to extract three credentials in the link, which is “domain“, “resid” and “user_info“, in this case, they are “https://xxx-my.sharepoint.com“, “blah-blah” and “xx_xxx_onmicrosoft_com” respectively. After getting the credentials, the direct download link can be generated by following pattern:
1 | {domain}/personal/{user_info}/_layouts/15/download.aspx?share={resid} |
In this case, the direct download link should be:
1 | https://xxx-my.sharepoint.com/personal/xx_xxx_onmicrosoft_com/_layouts/15/download.aspx?share=blah-blah |
0x02 Code example
The following code is a example Java code to show you how to generate a OneDrive direct link from OneDrive share link.
