curl – Google日历“未经授权的WebHook回调频道”错误

我正在尝试使用Google日历设置推送通知.目前我正在使用 oAuth playground来了解它的工作原理.所以我选择了Calendar API v3,授权它,使用提供的授权代码和访问令牌,并查询以下URI： https://www.googleapis.com/calendar/v3/calendars/tl7grdo4gqdqj4gtanpioksi6k@group.calendar.google.com/events/watch.请求包含以下正文：


{
"id": "154345345-345345345",
"type": "web_hook",
"address": "https://www.somedomain.com/web_hook.php"
}


我已将域名添加到网站管理员工具以证明所有权,并将其添加到developers console中的“允许域名”列表中.

发送以下请求：


POST /calendar/v3/calendars/tl7grdo4gqdqj4gtanpioksi6k@group.calendar.google.com/events/watch HTTP/1.1
Host: www.googleapis.com
Content-length: 105

Authorization: Bearer <some access token>
{
"id": "154345345-345345345",
"address": "https://www.somedomain.com/web_hook.php"
}

产生以下响应：

"errors": [

}

}


我希望得到一些非常基本但具体的步骤,我需要遵循这些步骤以使其正常运行.谢谢你的帮助.
