将节点应用程序连接到Google Calendar API

对于我而言，以某种方式出乎意料的是，将我的nodejs应用程序连接到Google Calendar API确实是一项不平凡的任务。尽管对俄语中的连接选项进行了详细的描述，但我还是不得不遍历各种设置和配置的目录林。本文详细介绍了成功进行集成所必须采取的步骤。

集成的目标是使nodejs应用程序能够将事件发布到特定的日历。在此示例中，我们使用了常规的个人Google帐户。

创建日历

首先，您需要创建一个日历，我们将在其中发布事件。转到Google日历，然后单击“其他日历”旁边的“ + ”按钮，然后选择“创建日历”项：

填写表格，然后再次单击“创建日历”，但带有蓝色按钮：

谷歌已经动摇了很长时间，然后高兴地宣布新日历已经准备就绪。访问新的日历设置：

在设置中，我们主要对“日历集成”项感兴趣：

其中最有用的是“日历ID ”
