Google Drive API without Ouath and receive files - google-drive-api

We are building a web application that should get all files from a specific folder in our Drive (read only). The problem is that I can't find a way to access our files without using OAuth. Basically I would want to request our files using AJAX and present the contents of them on a page (without the user having to do anything). Is this at all possible and have I missed something?
Whenever I try something without using OAuth I get a global internalError (being related to authorization according to the current documentation).
The experience I'm trying to achieve:
User enters http://domain.com/posts > Get all public files from folder Y > Sort them by date > Show the titles in HTML > User clicks title > User is presented with full contents of the file as HTML.
Is this possible?
Thanks in advance! :)
UPDATE:
To clarify: I would want to depend on our API key only.

You can do it this way, without using Google Drive API:
Make the folder public
Copy the folder ID from the URL
Append it to https://googledrive.com/host/ e.g. https://googledrive.com/host/0BzEbtMoF6IXbaVN2Qmx1em9qS0k/
You will get a directory index with all files listed and if the (sub)folder contains an index.html file, it will be rendered instead.
To get the JSON or XML file list, use YQL.

Can download files (without file name or extension), but unable to see them?

I'm using the Google Drive API to generate a downloadable link for a file that looks like this:
https://www.googleapis.com/drive/v3/files/{file_id}?access_token={access_token}&alt=media
The problem is files are being downloaded without name and without extension.
If I add the extension manually after the file downloads it still works, but it's bad to tell my users they have to do that every time, and the user would have to know which extension the file actually has.
If I call https://www.googleapis.com/drive/v3/files/?access_token={access_token}
I can't see the files I've uploaded... I think it could be a problem related to having access to the files' metadata, but I did authorize the auth.files.metadata scope.
I generate the access token using the refresh token and obtained the refresh token from the Oauth Playground... I'm confident I used the proper credentials for my application, but I could triple-check if someone suggests this could be the problem.
What can I do to debug this?

Access publicly shared OneDrive folder via API

I have a publicly shared OneDrive folder with some various sub-folders and files. I.e. I have shared it via a link, so anyone with this link can access them.
Is there a way I can access these files from either client-side JavaScript or some server-side code via a REST API of some sort? Without having to use any sort of user-specific credentials?
What I've been trying
I've been looking at the Accessing Shared Content page, and it looks like what I want, but can't figure out how to use it.
I've taken something that looks like an id from the shared URL, which looks to be a long hexadecimal number (which seems to be an id pointing at me?), an !, and then a number (which I assume has to do with the shared resource).
I've then tried to stick it in this URL:
https://api.onedrive.com/v1.0/shares/<id>/root?expand=children
But I get back a 400 Bad Request, so something isn't quite right...
I'm thinking maybe some sort of authentication is missing, but since the shared files are public, I don't users to have to login with their credentials, and can't of course use my own in code.
I've tried to register an app, where I get an application id (guid) and can generate Passwords and Key-Pairs. Was hoping maybe I could use that, but don't see in the API how and where to actually use those...
Goal
The shared folder contains sheet music for a choir, that I'm responsible for keeping updated (and OneDrive syncing is super handy here).
Some members aren't very computer savvy, so I'd like to make seeing and downloading these files as easy as possible. The shared link with a "go here to this other strange site and find the files there"-text sort of works, but I would much rather like to list the files directly in a member-only area of our website. Basically just "here are the files, click on one to download it".
Yes, you can use the REST API to access the contents of a folder.
The API is the one you mentioned, the shares API. However, it sounds like you are perhaps using the wrong ID.
The most straightforward way to do this is to follow the instructions to encode the actual sharing URL into a token. This way you create a base64 encoded version of the sharing link, append a "u!" to the front of that string, and then make the exact call you already mentioned. You'll get back a list of the files in the shared folder and you can go from there.
Here's an example of this:
Here's a sharing link to a folder in OneDrive with some photos in it.
https://1drv.ms/f/s!AtuAM_NacwVahiFpuMGS_BiQCwWu
To convert this URL into the API, you first base64 encode the URL and append u!
u!aHR0cHM6Ly8xZHJ2Lm1zL2YvcyFBdHVBTV9OYWN3VmFoaUZwdU1HU19CaVFDd1d1
Now you can use this URL as the sharing token, and expand children and thumbnails:
https://api.onedrive.com/v1.0/shares/u!aHR0cHM6Ly8xZHJ2Lm1zL2YvcyFBdHVBTV9OYWN3VmFoaUZwdU1HU19CaVFDd1d1/root?expand=children
Clicking on this bottom link should give you the JSON response, which includes the shared folder and the children inside the folder.

Access public dropbox files (via shared link) without user authentication

I'm trying to integrate Dropbox into my web application in the following way:
Users can enter a Dropbox Share Link, i.e. a Dropbox folder that can be accessed by anyone, even without a dropbox account.
My application then grabs the images from the folder and displays them to all users of my application.
Now as far as I can tell, the Dropbox API doesn't allow this without sending the user through a full-blown OAuth process. But since the shared link is public anyway, I don't need (and don't want) access to the users Dropbox account.
Is there a way to access a shared link in a programmatic way (without parsing the DOM or similar hacks)? Maybe there is a query parameter on the shared link to retrieve the contents as JSON? If it exists, I didn't find any docs about it.
Surely I'm not the first one to try this, so please share your solutions!
No, there's no programmatic way to list folder contents from a share link. If you have a share link for a specific file, then you can convert the domain from www.dropbox.com to dl.dropboxusercontent.com, but this trick doesn't work on folders.

Generate a URL for Google Drive publicly shared files and access them

I have a collection of PDF files on a Google Drive. I have shared them and I want to be able to link to them from a list on a web site. What I'd like to be able to do is work out the file name of the PDF using information in the list. As a simple example, if my list contains items 1, 2 and 3 I'd like to be able to upload PDF files 1.PDF 2.PDF and 3.PDF to Google Drive then have the web site just link to those when a link is clicked and show the PDF files in the browser.
So, I guess I could do this just by uploading the PDF to Google Drive and manually adding a link to PDF on the web site. However, what I want to do is generate the link programmatically so that when I have, say, 50 PDF files I don't have to keep getting the link from Google Drive and adding it to the web site. The site should just work out that item 50, say, in the list will link to 50.PDF, for example.
I've tried to get the file id using the API but that requires the authorization token to be generated and manual intervention to take place, so that won't work. At least, not at the point where the file is viewed because the viewer is anonymous.
So my questions are:
Is it possible to work out what a file name will be on the drive using just something like an item number in a list?
I guess that there are maybe some other options - for example, when I add the items to the list on the web site programmatically, I could go and locate the google drive file manually using a web application and link it using the file id at that point. I could store the ID in a database - however, would any anonymous user then be able to just click on the file link on the web site and view the file?
Finally, can anyone think of another way to do this?
Any help would be appreciated! :)
Is it possible for you to use a service account? You can authorize the app with an account dedicated to your app and user doesn't need to authorize and authenticate. The files you will be uploading will be managed under the service account's Drive.
You can learn more about service accounts on https://developers.google.com/accounts/docs/OAuth2ServiceAccount
If you have implementation specific questions, please ask.
