# Google APIs Client Library for Go
|
|
|
|
## Status
|
|
[](https://travis-ci.org/google/google-api-go-client)
|
|
|
|
These are auto-generated Go libraries from the Google Discovery Service's JSON description files of the available "new style" Google APIs.
|
|
|
|
Due to the auto-generated nature of this collection of libraries, complete APIs or specific versions can appear or go away without notice.
|
|
As a result, you should always locally vendor any API(s) that your code relies upon.

$ go get google.golang.org/api/storage/v1

The package of a given import is the second-to-last component, before the version number.

## Application Default Credentials Example
|
|
|
|
Application Default Credentials provide a simplified way to obtain credentials
|
|
for authenticating with Google APIs.
|
|
|
|
The Application Default Credentials authenticate as the application itself,
|
|
which make them great for working with Google Cloud APIs like Storage or
|
|
Datastore. They are the recommended form of authentication when building
|
|
applications that run on Google Compute Engine or Google App Engine.
|
|
|
|
Default credentials are provided by the `golang.org/x/oauth2/google` package. To use them, add the following import:
|
|
|
|
```
|
|
import "golang.org/x/oauth2/google"
|
|
```
|
|
|
|
Some credentials types require you to specify scopes, and service entry points may not inject them. If you encounter this situation you may need to specify scopes as follows:
|
|
|
|
```
|
|
import (
|
|
"golang.org/x/net/context"
|
|
"golang.org/x/oauth2/google"
|
|
"google.golang.org/api/compute/v1"
|
|
)
|
|
|
|
func main() {
|
|
// Use oauth2.NoContext if there isn't a good context to pass in.
|
|
ctx := context.Background()
|
|
|
|
client, err := google.DefaultClient(ctx, compute.ComputeScope)
|
|
if err != nil {
|
|
//...
|
|
}
|
|
computeService, err := compute.New(client)
|
|
if err != nil {
|
|
//...
|
|
}
|
|
}
|
|
```
|
|
|
|
If you need a `oauth2.TokenSource`, use the `DefaultTokenSource` function:
|
|
|
|
```
|
|
ts, err := google.DefaultTokenSource(ctx, scope1, scope2, ...)
|
|
if err != nil {
|
|
//...
|
|
}
|
|
client := oauth2.NewClient(ctx, ts)
|
|
```
|
|
|
|
