Question

我已经下载了google-api-php-client来访问google api。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：未捕获的异常'Google_Service_Exception'，消息'错误调用GET https://www.googleapis.com/bigquery/v2/projects/projectID/datasets/datasetname/tables?key=API键：（401）需要登录'在C：\ xampp \ htdocs \ test \ google- api-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-client-master（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 - ＆gt;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在C：\ xampp \ htdocs \ test \ google-api-php-clien中第80行的t-master（2）\ google-api-php-client-master \ src \ Google \ Http \ REST.php

您需要使用OAUTH 2.0验证您的应用

$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);

我想从PHP脚本查询Google Big Query Dataset
