Chrome issues accessing shared files... #31

Closed sushibear closed 2 years ago

sushibear commented 3 years ago

This is just a blind guess and I am not sure if it by any chance could be the problem of this plugin, but is there a possibility that the MIME types set in Nextcloud and the MIME types set in Apache are completely ignored by the browser when accessing files thru a shared path?

I have problems for instance loading JPGs, PNGs or .js files from a share and get different behaviour loading these file types in different browsers.

Any ideas?

This app output Content-Type use nextcloud MimeTypeDetector, please check the file real type at nextcloud data storage place(default at nextcloud-install-path/data/username/files/file-path).

OK .. so I checked the type in the file system, which is image/png.

Safari, Firefox and Postman are properly show the image in the browser, only Chrome wants to download the shared files.

Do you have any idea why Chrome gets the wrong mime type from the cloud when I try to access the file?

ps: Content-Length: 0 looks suspicious to me. Even if I get a Status Code: 200 OK when accessing the file, the content length seems to be always 0. Maybe it's not a mime type issue but something else?

I think I got something... even though this is just a hint of what's going on here...

When I try to access a file thru sharing path in Chrome, I see the following error in the Nextcloud log:

Looks like even if I try to get the file from this path:

/apps/sharingpath/test/Photos/6bf2e4728956595bf6dc75bf126.png

it ends up with this path instead:

/apps/sharingpath/admin/Photos/6bf2e4728956595bf6dc75bf126.png

What do you think could cause this that it only happens in Chrome and nowhere else?

Maybe related to https://github.com/rookie0/nextcloud-sharing-path/issues/23#issuecomment-679144870, this app(or nextcloud) got wrong user.

I will follow up.

sushibear commented 3 years ago

Hey .. any news on this issue?
Really does look like it might be releated to #23

rookie0 commented 2 years ago

Fixed in v0.4.3
