我有这段代码，可以从我的日历中获取事件。

 <!--Add a button for the user to click to initiate auth sequence -->
 <button id="authorize-button" style="visibility: hidden">Authorize</button>

 <script type="text/javascript">
      // Enter a client ID for a web application from the Google Developer Console.
      // The provided clientId will only work if the sample is run directly from
      // https://google-api-javascript-client.googlecode.com/hg/samples/authSample.html
      // In your Developer Console project, add a JavaScript origin that corresponds to the domain

      // Enter the API key from the Google Developer Console - to handle any unauthenticated
      // requests in the code.
      // The provided key works for this sample only when run from

      // To enter one or more authentication scopes, refer to the documentation for the API.

我想从多个 Google 日历中获取事件。我应该进行哪些更改才能使其正常工作并访问不同人的多个日历？

Answer 1

如果您想访问不同人的多个日历，最好的方法是创建一个服务帐户（它将代表用户向 API 发送所有请求）。因此，不会提示用户使用同意屏幕进行身份验证以访问其日历。以下是步骤：

创建一个 service account 并且您作为域的管理员。
将所有日历共享到此服务帐户。
对于访问用户数据的服务帐户，请按照此 link 进行全域授权。

检查此 link 以获得 java 中的服务帐户示例代码。
