Google 的假期日历脚本 从 Google Group 电子邮件地址的成员那里获取假期事件，但仅限直接成员，因为它使用以下行：
let users = GroupsApp.getGroupByEmail(GROUP_EMAIL).getUsers();
和
getUsers()那么如何获取组的直接成员和间接成员并在谷歌的假期日历代码中实现呢？谷歌的代码是：

所以它似乎必须递归地完成，即使用 getGroups 查看其他组中有哪些组，并清除重复的成员，然后这样做直到找不到组内的更多组。
另一种方法是添加对多个手动组的支持（详见下面的解决方案 2）。
解决方案一：
所以我换了：
let users = GroupsApp.getGroupByEmail(GROUP_EMAIL).getUsers();
与：
let users = getAllMembers(GROUP_EMAIL);
并添加了这个功能：
function getAllMembers(groupEmail) {
var group = GroupsApp.getGroupByEmail(groupEmail);
var users = group.getUsers();
var childGroups = group.getGroups();
for (var i = 0; i < childGroups.length; i++) {
var childGroup = childGroups[i];
users = users.concat(getAllMembers(childGroup.getEmail()));
}
// Remove duplicate members
var uniqueUsers = [];
var userEmails = {};
for (var i = 0; i < users.length; i++) {
var user = users[i];
if (!userEmails[user.getEmail()]) {
uniqueUsers.push(user);
userEmails[user.getEmail()] = true;
}
}
return uniqueUsers;
}
完整版：
function getAllMembers(groupEmail) {
var group = GroupsApp.getGroupByEmail(groupEmail);
var users = group.getUsers();
var childGroups = group.getGroups();
for (var i = 0; i < childGroups.length; i++) {
var childGroup = childGroups[i];
users = users.concat(getAllMembers(childGroup.getEmail()));
}
// Remove duplicate members
var uniqueUsers = [];
var userEmails = {};
for (var i = 0; i < users.length; i++) {
var user = users[i];
if (!userEmails[user.getEmail()]) {
uniqueUsers.push(user);
userEmails[user.getEmail()] = true;
}
}
return uniqueUsers;

=======================================
解决方案 2 - 仅支持多个手动组的替代版本：
我换了
let users = GroupsApp.getGroupByEmail(GROUP_EMAIL).getUsers();
与：
let users = getUsersFromGroups(GROUP_EMAIL);
和
let GROUP_EMAIL = 'ENTER_GOOGLE_GROUP_EMAIL_HERE';
带有数组：
let GROUP_EMAIL = ['ENTER_GOOGLE_GROUP_EMAIL_HERE', 'ENTER_ANOTHER_GOOGLE_GROUP_EMAIL_HERE'];
并添加了这个功能（也删除了重复的成员）：
function getUsersFromGroups(groupEmails) {
let users = [];
for (let groupEmail of groupEmails) {
let groupUsers = GroupsApp.getGroupByEmail(groupEmail).getUsers();
for (let user of groupUsers) {
if (!users.some(u => u.getEmail() === user.getEmail())) {
users.push(user);
}
}
}
return users;
}
新的完整代码：
function getUsersFromGroups(groupEmails) {
let users = [];
for (let groupEmail of groupEmails) {
let groupUsers = GroupsApp.getGroupByEmail(groupEmail).getUsers();
for (let user of groupUsers) {
if (!users.some(u => u.getEmail() === user.getEmail())) {
users.push(user);
