我正在尝试使用PHP和V3api为谷歌日历设置推送通知。
我已经获得了Auth2.0权限，可以通过我的应用程序在谷歌上创建事件。现在我想知道用户何时对谷歌日历（CRUD操作）进行任何更改。
这是我的代码：
private $imageService;
public $google_client;
public $google_calendar;
public function __construct()
{
$this->imageService = new ImageService();
$this->google_client = new Google_Client();
$this->google_client->setApplicationName($_ENV['GOOGLE_APP_NAME']);
$this->google_client->setDeveloperKey($_ENV['GOOGLE_API_KEY']);
$this->google_client->setClientId($_ENV['CLIENT_ID']);
$this->google_client->setClientSecret($_ENV['CLIENT_SECRET']);
$this->google_client->setAccessType('offline');
$this->google_client->setIncludeGrantedScopes(true);
$this->google_client->setScopes(array('email', 'profile', 'https://www.googleapis.com/auth/plus.me', 'https://www.googleapis.com/auth/calendar'));
$this->google_calendar = new Google_Service_Calendar($this->google_client);
}
public function googleCalendarWatch($uuid){
$channel = new Google_Service_Calendar_Channel($this->google_client);
$channel->setId($uuid);
$channel->setType('web_hook');
$channel->setAddress("https://example.com/google/googleNotifications");
$channel->setExpiration("1919995862000");
$this->google_calendar->events->watch('primary', $channel);
}
这就是输出：
Google_Service_Calendar_Channel Object (
[internal_gapi_mappings:protected] => Array ( )
[address] =>
[expiration] => 1426272395000
[id] => aee2b430-34bf-42bc-a597-ada46db42799
[kind] => api#channel
[params] =>
[payload] =>
[resourceId] => 51IKGpOwCJ6EMraQMUc1_04MODk
[resourceUri] => https://www.googleapis.com/calendar/v3/calendars/primary/events?key=AIzaSyBFUvq3OZO6ugAKvz7l8NgLS0V6DUJq8Vc&alt=json
[token] =>
[type] =>
[modelData:protected] => Array ( )
[processed:protected] => Array ( ) )
到目前为止，我不知道为什么地址返回null，也许这就是问题所在。但我不知道该怎么修。
同样阅读这篇文章：#26730263和查看我自己的代码没有太大区别。
我做了谷歌说的所有事情，注册域，添加凭据，api密钥，允许推送域等等。。
为每个单独的资源创建一个通知通道，然后对该资源的任何修改都会得到通知。以下信息直接来自谷歌（创建通知渠道）。
发出手表请求：
每个可观察的Google日历API资源都有一个相关的观察方法，其URI如下：
https://www.googleapis.com/**apiName**/**apiVersion**/**resourcePath**/watch
要为有关特定资源更改的消息设置通知通道，请向该资源的监视方法发送POST请求。每个通知通道都与特定用户和特定资源（或资源集）相关联。除非当前用户拥有或有权访问此资源，否则监视请求将不会成功
示例：
开始关注给定日历上事件集合的更改：
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://example.com/notifications", // Your receiving URL.
...
"token": "target=myApp-myCalendarChannelDest", // (Optional) Your channel token.
"expiration": 1426325213000 // (Optional) Your requested channel expiration time.
}
}
