Google Indexing API调用不断返回403码

Question

每当我们从空缺提供者处收到空缺时，我都会尝试将其发送给Google Indexing API。但是，尽管设置了所有适当的权限，我仍然收到403状态代码。

我已遵循“ Prerequisites for the Indexing API”指南并创建了一个服务帐户。就我而言，我在Google Search Console中有4个域条目，因此我按照MarcQuay's answer并将服务帐户添加到所有4个条目中。

我使用以下代码来实现Google API客户端并进行调用。我们收到的每个空缺都会调用sendGoogleRequest（）方法。

// Google API setup
function sendGoogleRequest(array $aData, int $sStatus = 0)
{
    global $DOMAIN, $GOOGLE_AUTH_CONFIG, $GOOGLE_AUTH_SCOPE, $GOOGLE_API_ENDPOINT;

    $googleClient = new Google_Client();
    $googleClient->useApplicationDefaultCredentials();
    $googleClient->addScope([$GOOGLE_AUTH_SCOPE]);

    // Update Google Indexing API. This will notify Google that the URL should be crawled again.
    $httpClient = $googleClient->authorize();
    $endpoint = $GOOGLE_API_ENDPOINT;

    $sJobUrl = $DOMAIN . '/vacancies/' . $aData['url'];
    $sType = "";

    if (!empty($sStatus)) {
        switch ($sStatus) {
            case 1:
                $sType = "URL_UPDATED";
                break;
            case 2:
                $sType = "URL_DELETED";
                break;
        }
    }

    $content = "{
            \"url\": \"$sJobUrl\",
            \"type\": \"$sType\"
    }";

    $response = $httpClient->post($endpoint, ['body' => $content]);
    $status_code = $response->getStatusCode();
    return $status_code;
}

我已经尝试调试它，似乎$ googleClient-> authorize（）中的'$ credentials'为空。

$authHandler = $this->getAuthHandler();

if ($credentials) {
  $callback = $this->config['token_callback'];
  $http = $authHandler->attachCredentials($http, $credentials, $callback);
} elseif ($token) {
  $http = $authHandler->attachToken($http, $token, (array) $scopes);
} elseif ($key = $this->config['developer_key']) {
  $http = $authHandler->attachKey($http, $key);
}

return $http;
但是我不知道这可能是什么原因。 

使用此代码将为每个呼叫返回“ 403”。在浏览了很长时间的互联网之后，我似乎可以找到一个明确的答案，除了“确保服务帐户是所有者”之外，但正如前面所述，情况已经如此。

我希望有人可以帮助我，因为我在这个问题上停留的时间比我想承认的要长。

如果需要更多信息，我会很乐意更新我的答案。

EDIT：

根据请求，这是$ httpClient-> post（）调用返回的完整错误消息。

我最终通过使用服务帐户作为AuthConfig来解决此问题
