异步拉取谷歌日历

Question

        $client = new Client();
        $client->setClientId(config('services.google.client_id'));
        $client->setClientSecret(config('services.google.client_secret'));
        $client->setRedirectUri(config('services.google.redirect'));
        $client->setScopes(['https://www.googleapis.com/auth/calendar.readonly']);
 
        $service = new \Google\Service\Calendar($client);

        $item = new \Google\Service\Calendar\FreeBusyRequestItem();
        $item->setId('<calendar_id');

        $freebusy_req = new \Google\Service\Calendar\FreeBusyRequest();
        $freebusy_req->setTimeMin(date(DateTime::ATOM, strtotime('2022/01/28')));
        $freebusy_req->setTimeMax(date(DateTime::ATOM, strtotime('2022/01/29')));
        $freebusy_req->setTimeZone('Europe/Madrid');

        $freebusy_req->setItems([$item]);
        $query = $service->freebusy
            ->query($freebusy_req);

  {
  "error": {
    "code": 403,
    "message": "The request is missing a valid API key.",
    "errors": [
      {
        "message": "The request is missing a valid API key.",

我的用户已经通过了 oauth 并获得了访问其信息的权限。 但我想异步获取他们的日历可用性。

但是，运行上面的代码给了我 JSON 错误。我对oauth的了解非常有限。知道我缺少什么吗？谢谢你。

您的用户可能已经授权您的应用程序，但该代码没有执行任何操作来告诉授权服务器这一点。您传递的只是一个客户端 ID，为了访问之前已授权您的应用程序的用户的用户数据，您需要传递刷新令牌。

在下面的代码中，我已将用户授权存储在 $tokenPath 中，然后我可以将其加载。

function getClient()
{
    $client = new Client();
    $client->setApplicationName('Google calendarAPI PHP Quickstart');
    $client->setScopes('https://www.googleapis.com/auth/calendar');
    $client->setAuthConfig('C:\Development\FreeLance\GoogleSamples\Credentials\credentials.json');
    $client->setAccessType('offline');
    $client->setRedirectUri("http://127.0.0.1");
    $client->setPrompt('select_account consent');

    // Load previously authorized token from a file, if it exists.
    // The file token.json stores the user's access and refresh tokens, and is
    // created automatically when the authorization flow completes for the first
    // time.
    $tokenPath = 'token.json';
    if (file_exists($tokenPath)) {

            $accessToken = json_decode(file_get_contents($tokenPath), true);
            $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
            $client->setAccessToken($accessToken);
    }

    // If there is no previous token, or it's expired.
    if ($client->isAccessTokenExpired()) {
        // Refresh the token if possible, else fetch a new one.
        if ($client->getRefreshToken()) {
            $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        } else {
            // Request authorization from the user.
            $authUrl = $client->createAuthUrl();
            printf("Open the following link in your browser:\n%s\n", $authUrl);
            print 'Enter verification code: ';
            $authCode = trim(fgets(STDIN));

            // Exchange authorization code for an access token.
            $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);

            $client->setAccessToken($accessToken);

            // Check to see if there was an error.
            if (array_key_exists('error', $accessToken)) {
                throw new Exception(join(', ', $accessToken));
            }
        }
        // Save the token to a file.
        if (!file_exists(dirname($tokenPath))) {
            mkdir(dirname($tokenPath), 0700, true);
        }
        file_put_contents($tokenPath, json_encode($client->getAccessToken()));
    }
    return $client;
}
