storage: support reading last N bytes of a file Google Cloud Storage supports reading the last N bytes from a file if the Range header is given a negative offset like: Range: bytes=-N where N is an integer, as per https://cloud.google.com/storage/docs/xml-api/reference-headers#range This CL adds that support to NewRangeReader and requires users to pass in a negative offset and a negative length for example: r, err := obj.NewRangeReader(ctx, -10, -1) Fixes #1540 Change-Id: Ia6803713334516053994b5a7f1af9b8d5d9cd586 Reviewed-on: https://code-review.googlesource.com/c/gocloud/+/44131 Reviewed-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Frank Natividad <franknatividad@google.com> Reviewed-by: Emmanuel Odeke <emm.odeke@gmail.com>
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 use
$ go get -u cloud.google.com/go/...
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 godoc.org/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))
