我正在尝试通过Google Indexing API发送POST请求，但一直收到HTTP错误403（禁止访问）。
我的代码如下：
require_once '../google-api-php-client-2.2.2/vendor/autoload.php';
$client = new Google_Client();
$client->setDeveloperKey('xxxxxxxxxxxxxx');
$client->setAuthConfig('xxxxxxxxxxxxx.json');
$client->addScope('https://www.googleapis.com/auth/indexing');
$httpClient = $client->authorize();
$endpoint = 'https://indexing.googleapis.com/v3/urlNotifications:publish?key=xxxxxxxxxx';
$content = "{
\"url\": \"https://www.example.com/whatever.html\",
\"type\": \"URL_UPDATED\"
}";
$response = $httpClient->post($endpoint, [ 'body' => $content ]);
$status_code = $response->getStatusCode();
die('I am done...: ' . $status_code);
我的完整答复如下：

我了解“禁止”的含义，但我不明白为什么会收到错误消息。我已按照说明进行设置。我已经设置了API密钥。我什至设置了开始时没有任何限制（当然以后会限制它），我设置了服务帐户密钥，json文件存在于我调用它的位置（没有它，我会收到401错误，而不是403错误） ），并查看有关使用API密钥的帮助，我正确地传递了密钥。
我想念什么？
