Authentication required response when trying to access entries content

Hi,

First time trying to use UCD. Really good experience so far using the dashboard and CLI to upload content, but I'm having issues to access the content via the API.

So far I could access the bucket entries list using the API but I get an authentication error when trying to access any entry content with the "/buckets/{bucketid}/entries/{entryid}/content/" route.
I'm using the same authentication header that works to get the entries list via "/buckets/{bucketid}/entries" route.

Here is the full response text:
<?xml version='1.0' encoding='UTF-8'?><Error><Code>AuthenticationRequired</Code><Message>Authentication required.</Message></Error>

Side note, I can't get any route to return an OK response from the swagger UI. I tried with the 'raw' api key as the authorization header value, then the base64 encoded version but always get am Unauthorized response.

 

Thanks for the clarifications.

I can get the list of entries from the bucket so the api key does seem to be the problem.
Also, trying with curl as you proposed I can download any entry content.

Strangely enough, once I downloaded an entry content using curl I can then download it from my Unity exe, but not other entries.Could be something wrong with the way I call the API? I'm using BestHttp for network calls and the code looks something like this:

Code (CSharp):

1. string localFilePath = ...
2. Uri uri = ...
3.  
4. var request = new HTTPRequest(uri, HTTPMethods.Get, (req, resp) =>
5. {
6.     List<byte[]> fragments = resp.GetStreamedFragments();
7.     if (fragments == null)
8.         return;
9.  
10.     using (var fs = new FileStream(localFilePath, FileMode.Append))
11.     {
12.         foreach (byte[] data in fragments)
13.         {
14.             fs.Write(data, 0, data.Length);
15.         }
16.     }
17.    
18.     if (resp.IsStreamingFinished)
19.     {
20.        // done
21.     }
22. })
23. {
24.  
25.     UseStreaming = true,
26.     StreamFragmentSize = 1024 * 1024, // 1 Mo
27.     DisableCache = true
28. };
29.  
30. request.SetHeader("Authorization", $"Basic xxxxxxxxxxxxxxxxxxxxx");
31. request.Send();

EDIT: Just realized I'm using the management API instead of the client one... that probably does not help! Will probably have more luck with the client API.

 

Some updates. I finally managed to download files from UCD using the client API and removing the authorization header entirely.

Still, it's not clear how to get the list of files to download without going through the management API as well.
I don't see a route on the client API to get the current list of entries on a bucket, or a diff with a previous release to get the list of files to download.

I saw on a different thread you mentioned a manifest.json file that is somewhat hidden by default. Can I access this file on my bucket too, or is there a better way to access the entries to download?

 

The app I'm building has a list of animated models that user can browse and interact with. Some of the animations have subtitles as well. The idea to put them on a CDN is to push new animations and subtitles without asking users to download a new version of the app. So the list of entries is dynamic and will grow over time.

I would expect the client API to expose a way to get the list of files to download, update or delete based on the current local versions of the the files. I believe I can get there by using the management API though, or by generating a custom manifest file with a static address on the CDN, although that last option feels a bit risky since the data is accessible without authentication once you have the file address.

In that regard, I think the client API should require an authentication as well, or that it should at least be a choice left to the developer to protect the CDN data with a password or not.

I hope that gives you a better idea of my use case. Thanks.

 

What did you end up doing? I have similar needs. I want to download all the files that are currently missing from the local directory. For this I now use management API first to get a list of entries that I need to download, then client API to download them. This does work but if you ended up going a different route, I'd love to hear it.

@timtunity3d what is the reason that downloading content does work with client API + no authentication, but only works for some files when using management API + authentication?
