使用服务帐户通过 PHP API 访问 BigQuery 时出现“无效凭据”

Question

我正在尝试使用服务帐户通过 Google 的 php API 访问 Big Query。

<?php

require_once '../google-api-php-client/src/Google_Client.php';
require_once '../google-api-php-client/src/contrib/Google_BigqueryService.php';

define("CLIENT_ID", 'removed-removed.apps.googleusercontent.com');
define("SERVICE_ACCOUNT_NAME", 'removed-removed@developer.gserviceaccount.com');
define("KEY_FILE", '../../../key.p12');

define("PROJECT_ID", removed);

$client = new Google_Client();

$key = file_get_contents(KEY_FILE);

$client->setAssertionCredentials(new Google_AssertionCredentials(
                SERVICE_ACCOUNT_NAME,
                array('https://www.googleapis.com/auth/prediction'),
                $key)
);

$client->setClientId(CLIENT_ID);

// Instantiate a new BigQuery Client 
$service = new Google_BigqueryService($client);

try
{
    $service->tables->listTables(PROJECT_ID, "data");
} catch (Exception $e)
{
    echo $e->getMessage();
}

?>

调用 GET 时出错 https://www.googleapis.com/bigquery/v2/projects/removed/datasets/data/tables: (401) 无效的凭证

Answer 1

确保您使用的是正确的 OAuth 范围 - 上面代码中的范围适用于 Google Prediction API。使用 https://www.googleapis.com/auth/bigquery 获得对 BigQuery API 的完全访问权限。详细了解 BigQuery API authorization here。

例子：

$client->setAssertionCredentials(new Google_AssertionCredentials(
                SERVICE_ACCOUNT_NAME,
                array('https://www.googleapis.com/auth/bigquery'),
                $key)
);
