OAuth 2.0 适用于 Google 工作表但不适用于 Google 日历 API
OAuth 2.0 Works for Google Sheets but not for Google Calendar API
我将 Google API 用于 reading/writing Google 工作表和 Google 驱动器 API。
我最近分配了一个项目，需要发送日历邀请。该网站是托管在 Apache Tomcat 8.5 上的 JSF 页面。对于其他 API，我使用的是服务帐户。
我现在尝试以同样的方式授权日历服务，但失败了。第一行是表格服务授权成功，日历服务授权失败：
GoogleConnection: Absolut Path: H:/ownCloud/Wabco/Workspace/WabcoDiagram/WebContent/resources/webserviceaccount.json
GoogleConnection: Absolut Path: H:/ownCloud/Wabco/Workspace/WabcoDiagram/WebContent/resources/webserviceaccount.json
Exception in thread "main" java.lang.NoSuchMethodError: com.google.api.client.googleapis.services.json.AbstractGoogleJsonClient$Builder.setBatchPath(Ljava/lang/String;)Lcom/google/api/client/googleapis/services/AbstractGoogleClient$Builder;

at de.promolitor.wabcodiagramviewer.audit.AuditGoogleCalendar.main(AuditGoogleCalendar.java:156)
我的问题：
我可以使用服务帐户登录到 Google 日历 API，或者我必须做哪些更改，或者我的代码中是否存在其他错误？
我可以从 Web 服务服务帐户发送日历邀请并让另一个用户成为活动的管理员/创建者，以便他可以在必要时更改活动吗？这需要 "domain-wide authority" 吗？

My Questions: Can I login with a Service account into the Google Calendar API, or what are the changes I have to do, or is there another error in my code somewhere?
是的，您可以将服务帐户用于 Google 日历。您的代码在我看来没问题，您只需添加您已完成的日历范围，并在 Google 开发人员控制台中为服务帐户启用 google 日历 api。

是的，您可以使用服务帐户。您将必须让 Gsuit 管理员授予服务帐户访问日历的权限，然后它才能创建活动并邀请其他人。是的，它需要 "domain-wide authority"？插入活动后，您应该可以修补 活动并将其他人设置为组织者。 check this 已经有一段时间没做这个了，实在记不住了，抱歉。
