httpreplay: set request body to nil if empty httpreplay had a bug when a non-GET request had a zero-length body. It always reads the request body to log it, then replaces it with ``` ioutil.NopCloser(bytes.NewReader(data)) ``` (See snapshotBody.) When the body is empty, this interacts with the way the net/http package constructs the Content-Length header. When the http.Request.ContentLength field is non-zero, that is used as the header value. But when it is zero, the Content-Length header is only transmitted if Request.Body is nil. Since httpreplay set the body to something non-nil, Content-Length was not transmitted.n The end result is that a request made from the client with "Content-Length: 0" would be forwarded by the proxy without the header. This broke writing an empty object to Amazon S3. The fix is to explicitly set the body to nil for outgoing requests. It would be incorrect to do so in snapshotBody, because that function is also used for responses, and a response body must never be nil. Also: - Fix a bug in storage.TestIntegration_BucketPolicyOnly. It was using time.Now, breaking replay. - Re-record the storage integration test. - Re-record the bigquery integration test. I recently incremented the httpreplay log version, and it was using an older version.

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.
7 August 2018
As of November 1, the code in the repo will no longer support Go versions 1.8 and earlier. No one other than AppEngine users should be on those old versions, and AppEngine Standard and Flex will stop supporting new deployments with those versions on that date.
Changes have been moved to CHANGES.
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 https://godoc.org/cloud.google.com/go
Visit or join the google-api-go-announce group for updates on these packages.
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))
First create a datastore.Client to use throughout your application:
client, err := datastore.NewClient(ctx, "my-project-id")
if err != nil {
log.Fatal(err)
}
Then use that client to interact with the API:
type Post struct {
Title string
Body string `datastore:",noindex"`
PublishedAt time.Time
}
keys := []*datastore.Key{
datastore.NameKey("Post", "post1", nil),
datastore.NameKey("Post", "post2", nil),
}
posts := []*Post{
{Title: "Post 1", Body: "...", PublishedAt: time.Now()},
{Title: "Post 2", Body: "...", PublishedAt: time.Now()},
}
if _, err := client.PutMulti(ctx, keys, posts); err != nil {
log.Fatal(err)
}
First create a storage.Client to use throughout your application:
client, err := storage.NewClient(ctx)
if err != nil {
log.Fatal(err)
}
// Read the object1 from bucket. rc, err := client.Bucket("bucket").Object("object1").NewReader(ctx) if err != nil { log.Fatal(err) } defer rc.Close() body, err := ioutil.ReadAll(rc) if err != nil { log.Fatal(err) }
First create a pubsub.Client to use throughout your application:
client, err := pubsub.NewClient(ctx, "project-id")
if err != nil {
log.Fatal(err)
}
Then use the client to publish and subscribe:
// Publish "hello world" on topic1. topic := client.Topic("topic1") res := topic.Publish(ctx, &pubsub.Message{ Data: []byte("hello world"), }) // The publish happens asynchronously. // Later, you can get the result from res: ... msgID, err := res.Get(ctx) if err != nil { log.Fatal(err) } // Use a callback to receive messages via subscription1. sub := client.Subscription("subscription1") err = sub.Receive(ctx, func(ctx context.Context, m *pubsub.Message) { fmt.Println(m.Data) m.Ack() // Acknowledge that we've consumed the message. }) if err != nil { log.Println(err) }
First create a bigquery.Client to use throughout your application: snip:# (bq-1)
c, err := bigquery.NewClient(ctx, "my-project-ID") if err != nil { // TODO: Handle error. }
Then use that client to interact with the API: snip:# (bq-2)
// Construct a query. q := c.Query(` SELECT year, SUM(number) FROM [bigquery-public-data:usa_names.usa_1910_2013] WHERE name = "William" GROUP BY year ORDER BY year `) // Execute the query. it, err := q.Read(ctx) if err != nil { // TODO: Handle error. } // Iterate through the results. for { var values []bigquery.Value err := it.Next(&values) if err == iterator.Done { break } if err != nil { // TODO: Handle error. } fmt.Println(values) }
First create a logging.Client to use throughout your application: snip:# (logging-1)
ctx := context.Background() client, err := logging.NewClient(ctx, "my-project") if err != nil { // TODO: Handle error. }
Usually, you'll want to add log entries to a buffer to be periodically flushed (automatically and asynchronously) to the Stackdriver Logging service. snip:# (logging-2)
logger := client.Logger("my-log")
logger.Log(logging.Entry{Payload: "something happened!"})
Close your client before your program exits, to flush any buffered log entries. snip:# (logging-3)
err = client.Close() if err != nil { // TODO: Handle error. }
First create a spanner.Client to use throughout your application:
client, err := spanner.NewClient(ctx, "projects/P/instances/I/databases/D")
if err != nil {
log.Fatal(err)
}
// Simple Reads And Writes _, err = client.Apply(ctx, []*spanner.Mutation{ spanner.Insert("Users", []string{"name", "email"}, []interface{}{"alice", "a@example.com"})}) if err != nil { log.Fatal(err) } row, err := client.Single().ReadRow(ctx, "Users", spanner.Key{"alice"}, []string{"email"}) if err != nil { log.Fatal(err) }
