我想为谷歌日历 API 设置推送通知，只要谷歌日历 API上的特定资源发生变化，我的服务器就会收到通知。我想使用PHP 的 Google APIs 客户端库来做到这一点。

但似乎他们没有在 PHP 库中观看谷歌日历资源的方法。可能是其他库有watch方法，但我不太确定。

基本上要为特定资源设置推送通知，您必须将发布请求发送到这样的 URL...

POST https://www.googleapis.com/calendar/v3/calendars/my_calendar@gmail.com/events/watch
Authorization: Bearer auth_token_for_current_user
Content-Type: application/json

{
  "id": "01234567-89ab-cdef-0123456789ab", // Your channel ID.
  "type": "web_hook",
  "address": "https://mydomain.com/notifications" // Your receiving URL.
}

我可以在 PHP 中使用 curl 轻松做到这一点，但我的问题是该请求未使用 Google OAuth 令牌授权，因此会导致错误。

我想知道这个问题是否有解决方法......

更新

我试图在不添加正确标头的情况下将连接发送到 Google，因此出现授权错误。更正了该部分后，我仍然遇到Invalid Credentials错误问题。这是我的片段的样子......

    $url = sprintf("https://www.googleapis.com/calendar/v3/calendars/%s/events/watch", $calendar);

    /* setup the POST parameters */
    $fields = array(
        'id'        => "some_unique_key",
        'type'      => "web_hook",
        'address'   => sprintf("http://%s//event_status/update_google_events", $_SERVER['SERVER_NAME'])
        );

    /* convert the POST parameters to URL query */
    $fields_string = '';
    foreach ($fields as $key => $value) {
        $fields_string .= sprintf("%s=%s&", $key, $value);
    }
    rtrim($fields_string, '&');

    /* setup POST headers */
    $headers[] = 'Content-Type: application/json';
    $headers[] = 'Authorization: OAuth ' . $access_token;

    /* send POST request */
    $channel = curl_init();
    curl_setopt($channel, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($channel, CURLOPT_URL, $url);
    curl_setopt($channel, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($channel, CURLOPT_POST, true);
    curl_setopt($channel, CURLOPT_POSTFIELDS, $fields_string);
    curl_setopt($channel, CURLOPT_CONNECTTIMEOUT, 2);
    curl_setopt($channel, CURLOPT_TIMEOUT, 3);
    $response = curl_exec($channel);
    curl_close($channel);

    error_log($response);

这是我对问题的解决方案。通过在Google Playground 中摆弄一下，我弄清楚了我做错了什么。

我所做的是

基本上只是按照谷歌的文档设置推送通知。

$url = sprintf("https://www.googleapis.com/calendar/v3/calendars/%s/events/watch", $calendar);

/* setup the POST parameters */
$fields = json_encode(array(
    'id'        => "some_unique_key",
    'type'      => "web_hook",
    'address'   => sprintf("http://%s//event_status/update_google_events", $_SERVER['SERVER_NAME'])
    ));

/* setup POST headers */
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: Bearer ' . $access_token;

/* send POST request */
$channel = curl_init();
curl_setopt($channel, CURLOPT_HTTPHEADER, $headers);
curl_setopt($channel, CURLOPT_URL, $url);
curl_setopt($channel, CURLOPT_RETURNTRANSFER, true);
curl_setopt($channel, CURLOPT_POST, true);
curl_setopt($channel, CURLOPT_POSTFIELDS, $fields);
curl_setopt($channel, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($channel, CURLOPT_TIMEOUT, 3);
$response = curl_exec($channel);
curl_close($channel);

error_log($response);

我设法通过 php 客户端库来做到这一点：

$channel = new Google_Service_Calendar_Channel($client);
$channel->setId('00000000-0000-0000-0000-000000000001');
$channel->setType('web_hook');
$channel->setAddress('https://www.yourserver.com/handleWatch.php');
$watchEvent = $service->events->watch(yourCalendarId, $channel, array());
