Cloud Storage Client Libraries

This page shows how to get started with the new Cloud Client Libraries for the Google Cloud Storage API. Read more about the client libraries for Cloud APIs, including the older Google APIs Client Libraries, in Client Libraries Explained.

Installing the client library

C#

Install-Package Google.Cloud.Storage.V1

Go

go get -u cloud.google.com/go/storage

Java

If you are using Maven, add this to your pom.xml file: 
<dependency>
  <groupId>com.google.cloud</groupId>
  <artifactId>google-cloud-storage</artifactId>
  <version>1.6.0</version>
</dependency>
If you are using Gradle, add this to your dependencies: 
compile 'com.google.cloud:google-cloud-storage:1.6.0'
If you are using SBT, add this to your dependences: 
libraryDependencies += "com.google.cloud" % "google-cloud-storage" % "1.6.0"

Node.js

npm install --save @google-cloud/storage

PHP

composer require google/cloud-storage

Python

pip install --upgrade google-cloud-storage

Ruby

gem install google-cloud-storage

Using the client library

The following example shows how to use the client library. To run it on your local workstation you must first install the Google Cloud SDK and authenticate by running the following command:

gcloud auth application-default login

For information about authenticating in other environments, see setting up authentication for server to server production applications.

C#

using Google.Cloud.Storage.V1;
using System;
using System.Diagnostics;

namespace GoogleCloudSamples
{
    class StorageQuickstart
    {
        static void Main(string[] args)
        {
            // Your Google Cloud Platform project ID.
            string projectId = "YOUR-PROJECT-ID";


            // Instantiates a client.
            StorageClient storageClient = StorageClient.Create();

            // The name for the new bucket.
            string bucketName = projectId + "-test-bucket";
            try
            {
                // Creates the new bucket.
                storageClient.CreateBucket(projectId, bucketName);
                Console.WriteLine($"Bucket {bucketName} created.");
            }
            catch (Google.GoogleApiException e)
            when (e.Error.Code == 409)
            {
                // The bucket already exists.  That's fine.
                Console.WriteLine(e.Error.Message);
            }
        }
    }
}

Go

// Sample storage-quickstart creates a Google Cloud Storage bucket.
package main

import (
	"fmt"
	"log"

	// Imports the Google Cloud Storage client package.
	"cloud.google.com/go/storage"
	"golang.org/x/net/context"
)

func main() {
	ctx := context.Background()

	// Sets your Google Cloud Platform project ID.
	projectID := "YOUR_PROJECT_ID"

	// Creates a client.
	client, err := storage.NewClient(ctx)
	if err != nil {
		log.Fatalf("Failed to create client: %v", err)
	}

	// Sets the name for the new bucket.
	bucketName := "my-new-bucket"

	// Creates a Bucket instance.
	bucket := client.Bucket(bucketName)

	// Creates the new bucket.
	if err := bucket.Create(ctx, projectID, nil); err != nil {
		log.Fatalf("Failed to create bucket: %v", err)
	}

	fmt.Printf("Bucket %v created.\n", bucketName)
}

Java

// Imports the Google Cloud client library
import com.google.cloud.storage.Bucket;
import com.google.cloud.storage.BucketInfo;
import com.google.cloud.storage.Storage;
import com.google.cloud.storage.StorageOptions;

public class QuickstartSample {
  public static void main(String... args) throws Exception {
    // Instantiates a client
    Storage storage = StorageOptions.getDefaultInstance().getService();

    // The name for the new bucket
    String bucketName = args[0];  // "my-new-bucket";

    // Creates the new bucket
    Bucket bucket = storage.create(BucketInfo.of(bucketName));

    System.out.printf("Bucket %s created.%n", bucket.getName());
  }
}

Node.js

// Imports the Google Cloud client library
const Storage = require('@google-cloud/storage');

// Your Google Cloud Platform project ID
const projectId = 'YOUR_PROJECT_ID';

// Instantiates a client
const storage = Storage({
  projectId: projectId
});

// The name for the new bucket
const bucketName = 'my-new-bucket';

// Creates the new bucket
storage.createBucket(bucketName)
  .then(() => {
    console.log(`Bucket ${bucketName} created.`);
  })
  .catch((err) => {
    console.error('ERROR:', err);
  });

PHP

# Includes the autoloader for libraries installed with composer
require __DIR__ . '/vendor/autoload.php';

# Imports the Google Cloud client library
use Google\Cloud\Storage\StorageClient;

# Your Google Cloud Platform project ID
$projectId = 'YOUR_PROJECT_ID';

# Instantiates a client
$storage = new StorageClient([
    'projectId' => $projectId
]);

# The name for the new bucket
$bucketName = 'my-new-bucket';

# Creates the new bucket
$bucket = $storage->createBucket($bucketName);

echo 'Bucket ' . $bucket->name() . ' created.';

Python

# Imports the Google Cloud client library
from google.cloud import storage

# Instantiates a client
storage_client = storage.Client()

# The name for the new bucket
bucket_name = 'my-new-bucket'

# Creates the new bucket
bucket = storage_client.create_bucket(bucket_name)

print('Bucket {} created.'.format(bucket.name))
