Hey. What's the purpose of this? I was trying to serve one of my gdrive folders with Nginx autoindex and came across your gist...

@dvdblk
Hi!
I was used this code to pipe Google Drive files through me server.

Not sure it is possible to make Nginx autoindex works with Google Drive since Google Drive using specific api for list folders and files.
Also you need be able to refresh access token every few hours. In my case it was handled by PHP.

Maybe it's possible to find workaround with lua-nginx or other scripting nginx modules, but you will need to implement whole logic with Google Drive by your own.

You can take a look at https://rclone.org/ and use it's own server or mount google drive via FUSE and serve mounted folder by nginx (but better use first option, FUSE is pretty slow);

Alright :) thanks a lot! I'll take a look at rclone.

@dvdblk You are welcome :)

Sorry, what is the location @dispose for?

@ripperdoc

I've used this location to call php script after download was finished or aborted.

proxy_set_header Host $server_name;

Means script placed on the same host

Since in my case it was Yii2 framework i've used action bound to /dl/dispose route

set $path https://127.0.0.1/dl/dispose;

If you don't need this feature you can remove whole location @dispose block and post_action @dispose; directive.

Please note as far as I know post_action is not documented and not recommended by nginx developers. Probably lua-nginx's log_by_* will be more safe and convinient.

Hi @userqq
Is this configuration use server bandwith for download or not?
and how to use this?
like accessing the file, for public shared google drive download link is using this url https://www.googleapis.com/drive/v3/files/[file_ID]?alt=media&key=[YOUR API KEY]
if using this configuration, how is the url structured?
is it using POST to example.com/dl/dispose with data file_id, filename and token ?

Hi @abdulaziz-git !
This configuration is USING server bandwith and NOT USING server local storage, file is profixied directly from google drive to client.
To use this you should have fastcgi server behind nginx (like PHP or any other) which will handle authorization token rotation.

For example:

• Client requesting http://site.com/index.php?fileId=123 which has real index.php script behing it.
• This index.php script should decide which exactly file you want send to client and where to get authorization token.
• Then index php responds with X-Accel-Redirect header (Please reffer to https://www.nginx.com/resources/wiki/start/topics/examples/x-accel/ for more information) and some additional data. X-Accel-Redirect header should contain path to valid nginx location.
• Nginx will intercept fastcgi response with X-Accel-Redirect header and run new location - location from X-Accel-Redirect header, but now nginx has variables with access token and fileId.

So to sum up:

• User requesting http://site.com/index.php?fileId=123 and receiving file directly from this URL.
• But behind scene there processing of index.php file and internal redirect in nginx

I'm not sure there is the possibility to download file without authorization token automatically, even if it public.

Also I can suggest to use https://rclone.org/, it should be much easier to configure.

Hi @userqq

Thanks for you explanation
I see so the function is same as using rclone mounting to folder and serve download through that folder

Thanks

Hi @abdulaziz-git !
As far as i know rclone able to serve files via http by itself, without mointing folder.
Please check https://rclone.org/commands/rclone_serve/

I was looking to see if it's possible to get gindex work with ngnix.
