name: cloud.google.com/go/storage
id: storage
summary: "<p>Package storage provides an easy way to work with Google Cloud Storage.\nGoogle
Cloud Storage stores data in named objects, which are grouped into buckets.</p>\n<p>More
information about Google Cloud Storage is available at\nhttps://cloud.google.com/storage/docs.</p>\n<p>See
https://godoc.org/cloud.google.com/go for authentication, timeouts,\nconnection
pooling and similar aspects of this package.</p>\n<p>All of the methods of this
package use exponential backoff to retry calls that fail\nwith certain errors,
as described in\nhttps://cloud.google.com/storage/docs/exponential-backoff. Retrying
continues\nindefinitely unless the controlling context is canceled or the client
is closed. See\ncontext.WithTimeout and context.WithCancel.</p>\n<h3>Creating
a Client</h3>\n<p>To start working with this package, create a client:</p>\n<pre
class=\"prettyprint\"><code>ctx := context.Background()\nclient, err := storage.NewClient(ctx)\nif
err != nil {\n // TODO: Handle error.\n}\n</code></pre><p>The client will use
your default application credentials. Clients should be\nreused instead of created
as needed. The methods of Client are safe for\nconcurrent use by multiple goroutines.</p>\n<p>If
you only wish to access public data, you can create\nan unauthenticated client
with</p>\n<pre class=\"prettyprint\"><code>client, err := storage.NewClient(ctx,
option.WithoutAuthentication())\n</code></pre><h3>Buckets</h3>\n<p>A Google Cloud
Storage bucket is a collection of objects. To work with a\nbucket, make a bucket
handle:</p>\n<pre class=\"prettyprint\"><code>bkt := client.Bucket(bucketName)\n</code></pre><p>A
handle is a reference to a bucket. You can have a handle even if the\nbucket doesn't
exist yet. To create a bucket in Google Cloud Storage,\ncall Create on the handle:</p>\n<pre
class=\"prettyprint\"><code>if err := bkt.Create(ctx, projectID, nil); err !=
nil {\n // TODO: Handle error.\n}\n</code></pre><p>Note that although buckets
are associated with projects, bucket names are\nglobal across all projects.</p>\n<p>Each
bucket has associated metadata, represented in this package by\nBucketAttrs. The
third argument to BucketHandle.Create allows you to set\nthe initial BucketAttrs
of a bucket. To retrieve a bucket's attributes, use\nAttrs:</p>\n<pre class=\"prettyprint\"><code>attrs,
err := bkt.Attrs(ctx)\nif err != nil {\n // TODO: Handle error.\n}\nfmt.Printf("bucket
%s, created at %s, is located in %s with storage class %s\\n",\n attrs.Name,
attrs.Created, attrs.Location, attrs.StorageClass)\n</code></pre><h3>Objects</h3>\n<p>An
object holds arbitrary data as a sequence of bytes, like a file. You\nrefer to
objects using a handle, just as with buckets, but unlike buckets\nyou don't explicitly
create an object. Instead, the first time you write\nto an object it will be created.
You can use the standard Go io.Reader\nand io.Writer interfaces to read and write
object data:</p>\n<pre class=\"prettyprint\"><code>obj := bkt.Object("data")\n//
Write something to obj.\n// w implements io.Writer.\nw := obj.NewWriter(ctx)\n//
Write some text to obj. This will either create the object or overwrite whatever
is there already.\nif _, err := fmt.Fprintf(w, "This object contains text.\\n");
err != nil {\n // TODO: Handle error.\n}\n// Close, just like writing a file.\nif
err := w.Close(); err != nil {\n // TODO: Handle error.\n}\n\n// Read it back.\nr,
err := obj.NewReader(ctx)\nif err != nil {\n // TODO: Handle error.\n}\ndefer
r.Close()\nif _, err := io.Copy(os.Stdout, r); err != nil {\n // TODO: Handle
error.\n}\n// Prints "This object contains text."\n</code></pre><p>Objects
also have attributes, which you can fetch with Attrs:</p>\n<pre class=\"prettyprint\"><code>objAttrs,
err := obj.Attrs(ctx)\nif err != nil {\n // TODO: Handle error.\n}\nfmt.Printf("object
%s has size %d and can be read using %s\\n",\n objAttrs.Name, objAttrs.Size,
objAttrs.MediaLink)\n</code></pre><h3>Listing objects</h3>\n<p>Listing objects
in a bucket is done with the Bucket.Objects method:</p>\n<pre class=\"prettyprint\"><code>query
:= &storage.Query{Prefix: ""}\n\nvar names []string\nit := bkt.Objects(ctx,
query)\nfor {\n attrs, err := it.Next()\n if err == iterator.Done {\n break\n
\ }\n if err != nil {\n log.Fatal(err)\n }\n names = append(names,
attrs.Name)\n}\n</code></pre><p>If only a subset of object attributes is needed
when listing, specifying this\nsubset using Query.SetAttrSelection may speed up
the listing process:</p>\n<pre class=\"prettyprint\"><code>query := &storage.Query{Prefix:
""}\nquery.SetAttrSelection([]string{"Name"})\n\n// ... as
before\n</code></pre><h3>ACLs</h3>\n<p>Both objects and buckets have ACLs (Access
Control Lists). An ACL is a list of\nACLRules, each of which specifies the role
of a user, group or project. ACLs\nare suitable for fine-grained control, but
you may prefer using IAM to control\naccess at the project level (see\nhttps://cloud.google.com/storage/docs/access-control/iam).</p>\n<p>To
list the ACLs of a bucket or object, obtain an ACLHandle and call its List method:</p>\n<pre
class=\"prettyprint\"><code>acls, err := obj.ACL().List(ctx)\nif err != nil {\n
\ // TODO: Handle error.\n}\nfor _, rule := range acls {\n fmt.Printf("%s
has role %s\\n", rule.Entity, rule.Role)\n}\n</code></pre><p>You can also
set and delete ACLs.</p>\n<h3>Conditions</h3>\n<p>Every object has a generation
and a metageneration. The generation changes\nwhenever the content changes, and
the metageneration changes whenever the\nmetadata changes. Conditions let you
check these values before an operation;\nthe operation only executes if the conditions
match. You can use conditions to\nprevent race conditions in read-modify-write
operations.</p>\n<p>For example, say you've read an object's metadata into objAttrs.
Now\nyou want to write to that object, but only if its contents haven't changed\nsince
you read it. Here is how to express that:</p>\n<pre class=\"prettyprint\"><code>w
= obj.If(storage.Conditions{GenerationMatch: objAttrs.Generation}).NewWriter(ctx)\n//
Proceed with writing as above.\n</code></pre><h3>Signed URLs</h3>\n<p>You can
obtain a URL that lets anyone read or write an object for a limited time.\nYou
don't need to create a client to do this. See the documentation of\nSignedURL
for details.</p>\n<pre class=\"prettyprint\"><code>url, err := storage.SignedURL(bucketName,
"shared-object", opts)\nif err != nil {\n // TODO: Handle error.\n}\nfmt.Println(url)\n</code></pre><h3>Post
Policy V4 Signed Request</h3>\n<p>A type of signed request that allows uploads
through HTML forms directly to Cloud Storage with\ntemporary permission. Conditions
can be applied to restrict how the HTML form is used and exercised\nby a user.</p>\n<p>For
more information, please see https://cloud.google.com/storage/docs/xml-api/post-object
as well\nas the documentation of GenerateSignedPostPolicyV4.</p>\n<pre class=\"prettyprint\"><code>pv4,
err := storage.GenerateSignedPostPolicyV4(bucketName, objectName, opts)\nif err
!= nil {\n // TODO: Handle error.\n}\nfmt.Printf("URL: %s\\nFields; %v\\n",
pv4.URL, pv4.Fields)\n</code></pre><h3>Errors</h3>\n<p>Errors returned by this
client are often of the type <a href=\"https://godoc.org/google.golang.org/api/googleapi#Error\"><code>googleapi.Error</code></a>.\nThese
errors can be introspected for more information by type asserting to the richer
<code>googleapi.Error</code> type. For example:</p>\n<pre class=\"prettyprint\"><code>if
