以下是完成此工作的步骤:

Here are the steps to follow to make this work:

在您的服务帐户中启用全域委派

1 - 为您的服务帐户提供日历范围

• 转到 https://admin.google.com/ 并使用 G Suite 帐户登录.莉>
• 转到安全 ->API 控制 ->全域委托
• 添加新 =>设置您的服务帐户的客户端 ID(只有数字的那个)
• 设置以下范围:https://www.googleapis.com/auth/calendar,https://www.googleapis.com/auth/calendar.events,https://www.googleapis.com/auth/admin.directory.resource.calendar

• Go to https://admin.google.com/ and login with G Suite account.
• Go to Security -> API Controls -> Domain-wide Delegation
• Add new => Set the client ID of your service account (The one that's only numbers)
• Set the following scopes: https://www.googleapis.com/auth/calendar,https://www.googleapis.com/auth/calendar.events,https://www.googleapis.com/auth/admin.directory.resource.calendar

2 - 您的用户需要具有 Service Account Token Creator 角色

• 转到https://console.cloud.google.com/iam-admin 然后
• 选择您的项目并转到左侧菜单中的 IAM.
• 选择您将用来模拟的帐户
• 点击编辑
• 添加角色服务帐户令牌创建者
• 根据 https://developers 为帐户启用域委托.google.com/admin-sdk/directory/v1/guides/delegation，部分要启用 G Suite 域范围的委派，请按照以下步骤操作.

• Go to https://console.cloud.google.com/iam-admin then
• Select your project and go to IAM in the left menu.
• Select the account that you will use to impersonate
• Click on edit
• Add role Service Account Token Creator
• Enable domain delegation for the account according to https://developers.google.com/admin-sdk/directory/v1/guides/delegation, section To enable G Suite domain-wide delegation, follow these steps.

3 - 在您要模拟的帐户中创建日历

服务帐户没有日历，因此您必须创建自己的日历

Service accounts don't have calendars so you have to create your own calendar

• 使用您想要拥有的电子邮件登录 https://calendar.google.com/日历(我使用了不同的帐户，与我要模拟的帐户不同，也许它可以使用模拟帐户中的日历)
• 创建日历
• 与有权修改和管理日历的服务帐户共享日历
• 与您要模拟的帐户共享日历，并有权修改和管理日历

• Login in https://calendar.google.com/ with the email that you want to own the calendar (I used a different account, not the same that I was going to impersonate, maybe it works using a calendar in the impersonated account)
• Create a calendar
• Share the calendar with the service account with permissions to modify and manage the calendar
• Share the calendar with the account you will impersonate with permissions to modify and manage the calendar

创建谷歌客户端

• 验证您的服务帐户.(我使用了 JSON 密钥，我不确定其他身份验证是否适用于此目的)

代码示例:(我使用的是 PHP，但我假设其他语言非常相似，因此您可以以此为指导)

Code sample: (I used PHP but I assume that other languages are very similar so you can use this as guideline)

请注意，使用某些电子邮件进行 IMPERSONALIZATION 至关重要.否则，将保留 403 错误，将其用于身份验证，有关详细信息，请参阅 Maksym Kalin 响应.

$google_client = new Google_Client();
$google_client->setAuthConfig($LOCATION_OF_JSON_KEY);
$google_client->setAccessType( 'offline' );
$google_client->setSubject('EmailToImpersonate@SomeAddress.com');
$google_client->setApplicationName("YourApplicationName");
$google_client->setScopes([Google_Service_Calendar::CALENDAR, Google_Service_Calendar::CALENDAR_EVENTS]);

与受邀者一起创建活动 :) 并享受！

注意: 通过这种方法，您可以创建活动并邀请人们加入.请记住 G Suite 的限制 https://support.google.com/a/answer/2905486 因此，如果您想创建许多事件，则需要有一个带有日历池的服务帐户池.

Note: With this approach you can create events and invite people to it. Keep in mind the limits of the G Suite https://support.google.com/a/answer/2905486 so if you want to create many events you will need to have a pool of service accounts with a pool of calendars.
