You can access Google Cloud Storage through three request endpoints (URIs). Which one you use depends on the operation you are performing.
Typical API Requests
You can use the following URLs to access an object:
- XML API
- JSON API
These URLs support secure sockets layer (SSL) encryption, which means you can use either HTTP or HTTPS. If you authenticate to the Google Cloud Storage API using OAuth 2.0, you should use HTTPS.
A CNAME redirect is a special DNS record that lets you use a URL from your own domain to access a resource (bucket and object) in Google Cloud Storage without revealing the Google Cloud Storage URI. To do this, you must use the following URI in the host name portion of your CNAME record:
For example, let's assume your domain is example.com and you want to make travel
maps available to your customers. You could create a bucket in Google Cloud Storage
travel-maps.example.com, and then create a CNAME record in DNS that
redirects requests from
travel-maps.example.com to the Google Cloud Storage URI. To do
this, you publish the following CNAME record in DNS:
travel-maps.example.com CNAME c.storage.googleapis.com.
By doing this, your customers can use the following URL to access a map of Paris:
Authenticated Browser Downloads
The Google Cloud Storage authentication and authorization models support authenticated browser downloads, which lets a user download data through their browser if they are logged in to their Google account and they have been granted permission to read the data. Authenticated browser downloads use cookie-based Google account authentication in conjunction with Google account-based ACLs. To download an object using cookie-based authentication you must use the following URL:
