我想从有权访问文件和文件夹的人员列表中删除某人。如何快速从所有文件中删除查看器或编辑器
我可以做到这一点使用下面的代码，但由于我有很多文件需要很长时间，我不得不多次重新启动过程并手动更改变量（var count = 5600）几次以获得任务完成。
这不可能是正确的解决方案，所以我想知道：
a）是否可以通过一次调用从所有文件（和文件夹）中删除用户？
b）如何快速（er）从一堆文件/文件夹中删除查看器？
我知道我可以使用continuationtoken来避免在重启之间更改代码，但我没有尝试过。
function removeUser()
{
var userName = 'John Doe';
removeUserFromViewersAndEditors_(userName);
};
function removeUserFromViewersAndEditors_(userName)
{ // Remove a user from viewers and editors
// Currently maximum runtime will be exceeded. Using a continuationtoken and automatically starting batches it is possible
// to make it run a sequence of batches and perform its task.
// As this script will not be run often, a manual approach is preferred for now.
// Start with count = 0 and phase = 0
// After the program finishes change phase = 1 and start again
// The program will stop on execution time limit reached change count = ?? based on the log and start again
var count = 5600; // Update if maximum runtime exceeded
var phase = 1; // Update if maximum runtime exceeded
var user = findUser_(userName, phase, count);
var totalRemovedFolders = 0;
var totalRemovedFiles = 0;
if (user != null)
{
if (phase == 0)
{
var countFolders = 0;
var folders = DriveApp.getFolders();
while(folders.hasNext())
{
if (removeUserFromFolderOrFile_(folders.next(), user) == true) totalRemovedFolders++;
countFolders++;
}
Logger.log('testRemoveUser Folders : count= ' + countFolders + ' totalRemovedFolders= ' + totalRemovedFolders);
}
else if (phase == 1)
{
var countFiles = count;
var files = DriveApp.getFiles();
while(count--) files.next(); // Skip a number of files
while(files.hasNext())
{
if (removeUserFromFolderOrFile_(files.next(), user) == true) totalRemovedFiles++;
countFiles++;
if ((100 * ((countFiles/100) | 0)) == countFiles)
{
Logger.log('phase= ' + phase + ' count= ' + countFiles + ' user= ' + userName + ((user == null) ? '' : ' found totalRemovedFiles= ' + totalRemovedFiles));
}
}
Logger.log('testRemoveUser Files : count= ' + countFiles + ' totalRemoved= ' + totalRemovedFiles);
}
}
Logger.log('totalRemoved= ' + (totalRemovedFolders + totalRemovedFiles));
