通过POST请求进行Google Calendar api身份验证

我已尝试创建对 www的POST请求.googleapis/calendar/v3/calendars/ calendarId /events，其中JSON密钥的内容作为 Authorization 标头的值，但我收到了以下错误:

I've tried to create a POST request to www.googleapis/calendar/v3/calendars/calendarId/events with the contents of the JSON key as the value of the Authorization header, but I receive the following error:

{错误": {错误":[{"domain":"global"，"reason":"authError"，"message":无效的凭证"，"locationType":"header"，位置":授权"}]，代码":401，"message":无效的凭据"}}

我是否缺少某些步骤，或者我不正确理解身份验证过程?非常感谢您的帮助.
