Two different links to an image in a bucket? What's the difference?

While ago I've uploaded an image to the Google Cloud Platform bucket and made it public. Direct link, from GCP looks like this:

GCP Bucket View

But this link, when put as Avatar URL to the Hangouts Chat API is not working (showing default avatar on hangouts chat, instead of mine).

I also found a way to create an url, its: https://storage.googleapis.com/[bucket]/[file] and this one is working, no idea why.

And my question is, why "official" link is not working, while the second one is working? What's the difference between them, difference between storage.cloud.google.com vs storage.googleapis.com?

Solution

  • This should help you understand better what's the difference between the two links.

    Access to public objects All requests to the storage.cloud.google.com URI require authentication. This applies even when allUsers have permission to access an object. If you want users to download anonymously accessible objects without authenticating, use the storage.googleapis.com URI documented in Direct API requests. For details and examples, see Accessing Public Data.

    Here you have more information on the topic.

    Hope this helps :)
