Google 云 API PHP 使用服务帐户的客户端身份验证

Question

我正在使用 PHP 处理一个项目，需要使用 PHP 客户端库实施 Google 云 API，但身份验证似乎对我不起作用。我已经创建了一个服务帐户并授予项目所有者权限，我不想使用 GOOGLE_DEFAULT_CREDENTIALS 环境变量进行身份验证，我想使用服务帐户身份验证。

这是我尝试过的方法：

require 'vendor/autoload.php';
use Google\Cloud\Core\ServiceBuilder;
use Google\Cloud\Storage\StorageClient;

// Authentication with Google Cloud Platform
$client = new ServiceBuilder([
    'keyFilePath' => 'api-project-374381085870-eaf930d9ffd7.json'
]);
$client = new StorageClient();
$bucket = $client->bucket('storage_client');

// Upload a file to the bucket.
$bucket->upload(
    fopen('file.txt', 'r')
);

但它 returns 错误为：

Warning: file_get_contents(/Users/abdul/.config/gcloud/application_default_credentials.json): failed to open stream: Permission denied in /Applications/XAMPP/xamppfiles/htdocs/storage/vendor/google/auth/src/CredentialsLoader.php on line 102

请帮帮我！

提前致谢！

Answer 1

密钥文件配置必须提供给被调用的客户端。 ServiceBuilder 通常很方便，因为它允许您使用您的配置创建单个实例，并将该配置传递给每个新客户端。

在您的示例中，您创建了一个带有密钥文件的 ServiceBuilder 实例，但您并未使用该实例调用 Storage。

两个选项：

use Google\Cloud\Core\ServiceBuilder;

$cloud = new ServiceBuilder([
    'keyFilePath' => 'my-keyfile.json'
]);

$storage = $cloud->storage();

或

use Google\Cloud\Storage\StorageClient;

$storage = new StorageClient([
    'keyFilePath' => 'my-keyfile.json'
]);

在这两个示例中，$storage 应该经过身份验证并可以使用！

此问题是由于您创建 StorageClient 对象和指定私钥文件参数的方式造成的。

您可以在 Google Cloud Platform 站点上找到以下 Pass the path to the service account key in code 示例，这对您的问题非常有用：

namespace Google\Cloud\Samples\Auth;

// Imports the Google Cloud Storage client library.
use Google\Cloud\Storage\StorageClient;

function auth_cloud_explicit($projectId, $serviceAccountPath)
{
    # Explicitly use service account credentials by specifying the private key
    # file.
    $config = [
        'keyFilePath' => $serviceAccountPath,
        'projectId' => $projectId,
    ];
    $storage = new StorageClient($config);

    # Make an authenticated API request (listing storage buckets)
    foreach ($storage->buckets() as $bucket) {
        printf('Bucket: %s' . PHP_EOL, $bucket->name());
    }
}
