上传对象

本页面介绍如何将对象上传到 Cloud Storage 存储分区。上传的对象包含要存储的数据以及所有关联元数据。如需对象的概览，请参阅关键术语并查看对象命名要求。

Console

  1. 在 Google Cloud Platform Console 中打开 Cloud Storage 浏览器。
    打开 Cloud Storage 浏览器

  2. 在存储分区列表中，点击要将对象上传到的存储分区的名称。

  3. 在存储分区的对象标签中，执行以下任一操作：

    • 将所需文件从桌面或文件管理器拖放到 GCP Console 的主窗格中。

    • 点击上传文件按钮，在出现的对话框中选择要上传的文件，然后点击打开。

gsutil

使用 gsutil cp 命令，将 [VALUES_IN_BRACKETS] 替换为适当的值：

gsutil cp [LOCAL_OBJECT_LOCATION] gs://[DESTINATION_BUCKET_NAME]/

如果成功，则响应类似如下示例：

Operation completed over 1 objects/58.8 KiB.

代码示例

C++

如需了解详情，请参阅 Cloud Storage C++ API 参考文档。 

namespace gcs = google::cloud::storage;
using ::google::cloud::StatusOr;
[](gcs::Client client, std::string file_name, std::string bucket_name,
   std::string object_name) {
  // Note that the client library automatically computes a hash on the
  // client-side to verify data integrity during transmission.
  StatusOr<gcs::ObjectMetadata> object_metadata = client.UploadFile(
      file_name, bucket_name, object_name, gcs::IfGenerationMatch(0));

  if (!object_metadata) {
    throw std::runtime_error(object_metadata.status().message());
  }

  std::cout << "Uploaded " << file_name << " to object "
            << object_metadata->name() << " in bucket "
            << object_metadata->bucket()
            << "\nFull metadata: " << *object_metadata << "\n";
}

C#

如需了解详情，请参阅 Cloud Storage C# API 参考文档。 

private void UploadFile(string bucketName, string localPath,
    string objectName = null)
{
    var storage = StorageClient.Create();
    using (var f = File.OpenRead(localPath))
    {
        objectName = objectName ?? Path.GetFileName(localPath);
        storage.UploadObject(bucketName, objectName, null, f);
        Console.WriteLine($"Uploaded {objectName}.");
    }
}

Go

如需了解详情，请参阅 Cloud Storage Go API 参考文档。 

f, err := os.Open("notes.txt")
if err != nil {
	return err
}
defer f.Close()

wc := client.Bucket(bucket).Object(object).NewWriter(ctx)
if _, err = io.Copy(wc, f); err != nil {
	return err
}
if err := wc.Close(); err != nil {
	return err
}

Java

如需了解详情，请参阅 Cloud Storage Java API 参考文档。 

Storage storage = StorageOptions.getDefaultInstance().getService();
BlobId blobId = BlobId.of("bucket", "blob_name");
BlobInfo blobInfo = BlobInfo.newBuilder(blobId).setContentType("text/plain").build();
Blob blob = storage.create(blobInfo, "Hello, Cloud Storage!".getBytes(UTF_8));

Node.js

如需了解详情，请参阅 Cloud Storage Node.js API 参考文档。 

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

// Creates a client
const storage = new Storage();

/**
 * TODO(developer): Uncomment the following lines before running the sample.
 */
// const bucketName = 'Name of a bucket, e.g. my-bucket';
// const filename = 'Local file to upload, e.g. ./local/path/to/file.txt';

// Uploads a local file to the bucket
await storage.bucket(bucketName).upload(filename, {
  // Support for HTTP requests made with `Accept-Encoding: gzip`
  gzip: true,
  // By setting the option `destination`, you can change the name of the
  // object you are uploading to a bucket.
  metadata: {
    // Enable long-lived HTTP caching headers
    // Use only if the contents of the file will never change
    // (If the contents will change, use cacheControl: 'no-cache')
    cacheControl: 'public, max-age=31536000',
  },
});

console.log(`${filename} uploaded to ${bucketName}.`);

PHP

如需了解详情，请参阅 Cloud Storage PHP API 参考文档。 

use Google\Cloud\Storage\StorageClient;

/**
 * Upload a file.
 *
 * @param string $bucketName the name of your Google Cloud bucket.
 * @param string $objectName the name of the object.
 * @param string $source the path to the file to upload.
 *
 * @return Psr\Http\Message\StreamInterface
 */
function upload_object($bucketName, $objectName, $source)
{
    $storage = new StorageClient();
    $file = fopen($source, 'r');
    $bucket = $storage->bucket($bucketName);
    $object = $bucket->upload($file, [
        'name' => $objectName
    ]);
    printf('Uploaded %s to gs://%s/%s' . PHP_EOL, basename($source), $bucketName, $objectName);
}

Python

如需了解详情，请参阅 Cloud Storage Python API 参考文档。

使用 Blob.upload_from_file()、Blob.upload_from_filename() 或 Blob.upload_from_string() 方法上传对象。 
def upload_blob(bucket_name, source_file_name, destination_blob_name):
    """Uploads a file to the bucket."""
    storage_client = storage.Client()
    bucket = storage_client.get_bucket(bucket_name)
    blob = bucket.blob(destination_blob_name)

    blob.upload_from_filename(source_file_name)

    print('File {} uploaded to {}.'.format(
        source_file_name,
        destination_blob_name))

Ruby

如需了解详情，请参阅 Cloud Storage Ruby API 参考文档。 

# project_id        = "Your Google Cloud project ID"
# bucket_name       = "Your Google Cloud Storage bucket name"
# local_file_path   = "Path to local file to upload"
# storage_file_path = "Path to store the file in Google Cloud Storage"

require "google/cloud/storage"

storage = Google::Cloud::Storage.new project_id: project_id
bucket  = storage.bucket bucket_name

file = bucket.create_file local_file_path, storage_file_path

puts "Uploaded #{file.name}"

REST API

JSON API

  1. 从 OAuth 2.0 Playground 获取授权访问令牌。将 Playground 配置为使用您自己的 OAuth 凭据。
  2. 将对象的数据添加到请求正文。
  3. 使用 cURL，通过 POST Object 请求调用 JSON API，将 [VALUES_IN_BRACKETS] 替换为适当的值：
    curl -X POST --data-binary @[OBJECT] \
    -H "Authorization: Bearer [OAUTH2_TOKEN]" \
    -H "Content-Type: [OBJECT_CONTENT_TYPE]" \
    "https://www.googleapis.com/upload/storage/v1/b/[BUCKET_NAME]/o?uploadType=media&name=[OBJECT_NAME]"

如需详细了解如何使用 JSON API 上传对象，请参阅执行简单上传。

XML API

  1. 从 OAuth 2.0 Playground 获取授权访问令牌。将 Playground 配置为使用您自己的 OAuth 凭据。
  2. 将对象的数据添加到请求正文。
  3. 使用 cURL，通过 PUT Object 请求调用 XML API，将 [VALUES_IN_BRACKETS] 替换为适当的值：
    curl -X PUT --data-binary @[OBJECT] \
    -H "Authorization: Bearer [OAUTH2_TOKEN]" \
    -H "Content-Type: [OBJECT_CONTENT_TYPE]" \
    "https://storage.googleapis.com/[BUCKET_NAME]/[OBJECT_NAME]"
