Question

我正在尝试使用PHP和V3 api为Google日历设置推送通知。

我获得了Auth2.0权限，并且能够从我的应用程序在谷歌上创建事件。现在我想知道用户何时在谷歌日历上进行任何更改（CRUD操作）。

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);

}

这输出了这个：

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。但我不知道如何解决它。

另外阅读：#26730263并查看我自己的代码并没有太大的不同。

我做了google所说的所有内容，注册域名，添加凭据，api密钥，允许推送域名等等。

Answer 1

为每个资源创建一个通知渠道，然后对该资源进行任何修改，然后通知您。以下信息直接来自Google（创建通知渠道）。

制作观看请求：

每个可观看的Google Calendar API资源在以下格式的URI中都有一个关联的监视方法：

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，请向资源的watch方法发送POST请求。每个通知信道都与特定用户和特定资源（或一组资源）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的一系列事件的更改：

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. } }

地址？

令牌？
