该服务目前不可用 Google api

Question

我正在使用 google Slide 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：

致命错误：未捕获的 Google_Service_Exception: { "error": { "code": 503, "message": "该服务当前不可用。", "errors": [ { "message": "该服务当前不可用。", /vendor/google/apiclient/src/Google/Http/REST.php:118 中的“domain”：“global”，“reason”：“backendError” } ]，“status”：“UNAVAILABLE” } } 堆栈跟踪：# 0 /vendor/google/apiclient/src/Google/Http/REST.php(94): Google_Http_REST::decodeHttpResponse(对象(GuzzleHttp\Psr7\Response)，对象(GuzzleHttp\Psr7\Request)，'Google_Service_...' ) #1 /vendor/google/apiclient/src/Google/Task/Runner.php(181): Google_Http_REST::doExecute(对象(GuzzleHttp\Client), 对象(GuzzleHttp\Psr7\Request), 'Google_Service_...' ) #2 /vendor/google/apiclient/src/Google/Http/REST.php(58): Google_Task_Runner->在 /vendor/google/apiclient/src/Google/Http/REST.php 第 118 行运行

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有这个值：

'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

幻灯片肯定可以提供更好的错误消息，但我很确定问题在于http://localhost:9880/wp-content/uploads/2017/02/pla23.jpg您尝试插入的图像 URL。我尝试使用replaceAllShapesWithImage该图像发出请求，也得到了 503。

幻灯片通过公共互联网下载您的图像，因此localhost域不起作用。尝试将其托管在一些可公开访问的 URL 上，或者您可以使用Google 云端硬盘来托管图像。
