我想从 PHP 脚本中查询 Google Big Query Dataset

Question

我已经下载了用于访问 google api 的 google-api-php-client。 我的代码是 include_once "templates/base.php"; echo pageHeader("Simple API Access"); set_include_path("../src/" . PATH_SEPARATOR . get_include_path()); require_once 'Google/Client.php'; require_once 'Google/Service/Bigquery.php'; $client = new Google_Client(); $client->setApplicationName("my application name"); $apiKey = "--------my api key----"; $client->setDeveloperKey($apiKey); define("PROJECT_ID", my project ID); define("DATASET_ID", "my data set ID"); $service = new Google_Service_Bigquery($client); $results = $service->tables->listTables(PROJECT_ID, DATASET_ID); print_r($results); 如果我运行上面的文件，它会给出错误：致命错误：未捕获异常 'Google_Service_Exception' 并在 C:\xampp\htdocs\test\google-api- 中显示消息 'Error calling GET https://www.googleapis.com/bigquery/v2/projects/projectID/datasets/datasetname/tables?key=API key: (401) Login Required' php-client-master (2)\google-api-php-client-master\src\Google\Http\REST.php:80 堆栈跟踪：#0 C:\xampp\htdocs\test\google-api-php-客户端主 (2)\google-api-php-client-master\src\Google\Http\REST.php(44): Google_Http_REST::decodeHttpResponse(Object(Google_Http_Request)) #1 C:\xampp\htdocs\test \google-api-php-client-master (2)\google-api-php-client-master\src\Google\Client.php(499): Google_Http_REST::execute(Object(Google_Client), Object(Google_Http_Request)) #2 C:\xampp\htdocs\test\google-api-php-client-master (2)\google-api-php-client-master\src\Google\Service\Resource.php(195): Google_Client->执行（对象（Google_Http_Request））#3 C:\xampp\htdocs\test\google-api-php-client-master (2)\google-api-php-client-master\src\Google\Service\B in C :\xampp\htdocs\test\google-api-php-cl ient-master (2)\google-api-php-client-master\src\Google\Http\REST.php 在第 80 行

您需要使用 OAUTH2.0 对您的应用进行身份验证

$client = new Google_Client();
$client->setApplicationName("Client_Library_Examples");

if (isset($_SESSION['service_token'])) {
    $client->setAccessToken($_SESSION['service_token']);
}
$key = file_get_contents($key_file_location);
$cred = new Google_Auth_AssertionCredentials(
        $service_account_name, array(
    'https://www.googleapis.com/auth/bigquery',
        ), $key
);
$client->setAssertionCredentials($cred);
if ($client->getAuth()->isAccessTokenExpired()) {
    $client->getAuth()->refreshTokenWithAssertion($cred);
}
$_SESSION['service_token'] = $client->getAccessToken();
var_dump($_SESSION);
$bq = new Google_Service_Bigquery($client);
