该服务当前不可用 Google api

Question

我正在使用 google 幻灯片 API 连接到我的项目帐户，连接工作正常，但有时我会收到此错误：

Fatal error: Uncaught Google_Service_Exception: { "error": { "code": 503, "message": "The service is currently unavailable.", "errors": [ { "message": "The service is currently unavailable.", "domain": "global", "reason": "backendError" } ], "status": "UNAVAILABLE" } } in /vendor/google/apiclient/src/Google/Http/REST.php:118 Stack trace: #0 /vendor/google/apiclient/src/Google/Http/REST.php(94): Google_Http_REST::decodeHttpResponse(Object(GuzzleHttp\Psr7\Response), Object(GuzzleHttp\Psr7\Request), 'Google_Service_...') #1 /vendor/google/apiclient/src/Google/Task/Runner.php(181): Google_Http_REST::doExecute(Object(GuzzleHttp\Client), Object(GuzzleHttp\Psr7\Request), 'Google_Service_...') #2 /vendor/google/apiclient/src/Google/Http/REST.php(58): Google_Task_Runner->run in /vendor/google/apiclient/src/Google/Http/REST.php on line 118

这是我的 getClient 函数 Google API:

function getClient(string $SCOPES,string $CLIENT_SECRET_PATH,string $CREDENTIALS_PATH,string $APPLICATION_NAME) {

    $this->client->setApplicationName($APPLICATION_NAME);
    $this->client->setScopes($SCOPES);
    $this->client->setAuthConfig($CLIENT_SECRET_PATH);
    $this->client->setAccessType('offline');
    $this->client->setApprovalPrompt('force');

    $credentialsPath = $this->expandHomeDirectory($CREDENTIALS_PATH);
    if (file_exists($credentialsPath)) {
        $accessToken = json_decode(file_get_contents($credentialsPath), true);
    } else {

        $authUrl = $this->client->createAuthUrl();
        printf("Open the following link in your browser:\n%s\n", $authUrl);
        print 'Enter verification code: ';
        $authCode = trim(fgets(STDIN));

        $accessToken = $this->client->fetchAccessTokenWithAuthCode($authCode);

        if(!file_exists(dirname($credentialsPath))) {
            mkdir(dirname($credentialsPath), 0700, true);
        }
        file_put_contents($credentialsPath, json_encode($accessToken));
        printf("Credentials saved to %s\n", $credentialsPath);
    }
    $this->client->setAccessToken($accessToken);

    if ($this->client->isAccessTokenExpired()) {
        $this->client->fetchAccessTokenWithRefreshToken($this->client->getRefreshToken());
        file_put_contents($credentialsPath, json_encode($this->client->getAccessToken()));
    }
    return $this->client;
}

这是我发送的请求：

public function replaceAllShapesWithImage(array $data_images)
{
    $requests =array();
    if(isset($data_images)){
        foreach ($data_images as $key => $value) {
            $requests[] = new \Google_Service_Slides_Request(array(
                'replaceAllShapesWithImage' => array(
                    'imageUrl' => $value['url'],
                    'replaceMethod' => $value['replaceMethod'],
                    'containsText' => array(
                        'text' => $value['text']
                    )
                )
            ));
        }
    }
    return $requests;
}

$data_image 具有此值：

'replaceAllShapesWithImage' => array(
            0 => array(
                'text'=>'{{LOGO}}',
                'url'=>'http://www.16cafe.com/wp-content/themes/16cafe/css/images/logo.png',
                'replaceMethod'=>'CENTER_INSIDE'
            ),
            1 => array(
                'text'=>'{{PHOTO}}',
                'url'=>'http://localhost:9880/wp-content/uploads/2017/02/pla23.jpg',
                'replaceMethod'=>'CENTER_INSIDE'
            ),
        )

Answer 1

幻灯片绝对可以提供更好的错误消息，但我很确定问题出在您尝试插入的 http://localhost:9880/wp-content/uploads/2017/02/pla23.jpg 图片 URL 上。我尝试使用该图像发出 replaceAllShapesWithImage 请求，但也得到了 503。

Slides 通过 public 互联网下载您的图片，因此 localhost 域无法使用。尝试将其托管在一些 public 可以访问的 URL 上，或者您可以使用 Google Drive 来托管图像。

Answer 2

我收到了同样的错误消息（出于完全不同的原因）。

对我来说，我等了 30 秒，然后再次尝试同样的事情，它奏效了。

看来这可能只是 Google API.

的短暂中断

Answer 3

每次我发现 API 错误时，我的脚本都会等待 1 秒。如果错误再次发生，脚本将等待 2 秒。然后是4秒、8秒、16秒。我总共进行了 5 次尝试。每次都有效。

public function get_analytics_response()
{
    $api_call_num_of_attempts = 5;
    $api_call_attempts = 0;
    $api_call_sleep = 1;

    do {
        try {
            $response = $this->analytics->reports->batchGet();
        }
        catch (Google_Service_Exception $e) {
            // Sleep 1s, 2s, 4s, 8s, 16s + random milliseconds
            $sleep = ($api_call_sleep * 1000000) + rand(1000, 1000000);
            usleep($sleep);
            $api_call_attempts++;
            $api_call_sleep = $api_call_sleep * 2;

            $error_message_json = $e->getMessage();
            $error_message = json_decode($error_message_json, true);
            // Save errors...

            continue;
        }

        break;
    }
    while ($api_call_attempts < $api_call_num_of_attempts);

    return $response;
}
