storage: add Exists examples for BucketHandle, ObjectHandle While there isn't a top level method "Exists" for either of BucketHandle or ObjectHandle, the use of Attrs seems to require one to already be familiar with these libraries. In the related issue #1773, a customer tried to create a Reader just to check if an object existed. They performed an expensive call instead of just the cheap metadata check. This CL ensures that such guidance for checking if buckets and objects exist; these examples will be indexed by search engines and next time they won't have to go digging through the docs and experimenting with expensive APIs.

Go packages for Google Cloud Platform services.
import "cloud.google.com/go"
To install the packages on your system, do not clone the repo. Instead:
Change to your project directory:
cd /my/cloud/project
Get the package you want to use. Some products have their own module, so it's best to go get
the package(s) you want to use:
$ go get cloud.google.com/go/firestore # Replace with the package you want to use.
NOTE: Some of these packages are under development, and may occasionally make backwards-incompatible changes.
NOTE: Github repo is a mirror of https://code.googlesource.com/gocloud.
Alpha status: the API is still being actively developed. As a result, it might change in backward-incompatible ways and is not recommended for production use.
Beta status: the API is largely complete, but still has outstanding features and bugs to be addressed. There may be minor backwards-incompatible changes where necessary.
Stable status: the API is mature and ready for production use. We will continue addressing bugs and feature requests.
Documentation and examples are available at pkg.go.dev/cloud.google.com/go
We support the two most recent major versions of Go. If Google App Engine uses an older version, we support that as well.
By default, each API will use Google Application Default Credentials for authorization credentials used in calling the API endpoints. This will allow your application to run in many environments without requiring explicit configuration.
client, err := storage.NewClient(ctx)
To authorize using a JSON key file, pass option.WithCredentialsFile
to the NewClient
function of the desired package. For example:
client, err := storage.NewClient(ctx, option.WithCredentialsFile("path/to/keyfile.json"))
You can exert more control over authorization by using the golang.org/x/oauth2
package to create an oauth2.TokenSource
. Then pass option.WithTokenSource
to the NewClient
function: snip:# (auth-ts)
tokenSource := ...
client, err := storage.NewClient(ctx, option.WithTokenSource(tokenSource))
