操作Drive API 的CRUD
需要以下兩個scope

https://developers.google.com/drive/api/v3/reference/permissions/update
一.共用雲端硬碟
重點在這句, 需使用useDomainAdminAccess參數
Use the useDomainAdminAccess parameter with the drives and permissions resources to manage shared drives across an organization.
//https://developers.google.com/drive/api/guides/manage-shareddrives
DriveList driveList = service.drives().list()
.setQ("organizerCount = 0")
.setFields("nextPageToken, drives(id, name)")
.setUseDomainAdminAccess(true)
.setPageToken(pageToken)
.execute();
setQ 為篩選資料夾條件, 例如
.setQ("memberCount = 0") //雲端硬碟沒有成員
.setQ("organizerCount = 0") //沒有管理者
.setFields("nextPageToken, drives(id, name)")
回傳id,及name值
二 Permission
每個雲端硬碟會包含多個permission
https://developers.google.com/drive/api/v3/reference/permissions
列出特定共用雲端硬碟的所有permission
操作時需要加上
.setUseDomainAdminAccess(true) .setSupportsAllDrives(true)
否則只會找my drive, 發生找不到訊息
DriveList driveList = service.drives().list()
.setQ("name contains 'VMs'")
.setFields("nextPageToken, drives(id, name)")
.setUseDomainAdminAccess(true)
.setPageToken(pageToken)
.execute();
driveList.getDrives().forEach(drive -> {
logger.info(drive.getName());
// 列出permission list
try {
PermissionList permissionList = service.permissions()
.list(drive.getId())
.setFields("nextPageToken, permissions(id,emailAddress,role)")
.setUseDomainAdminAccess(true)
.setSupportsAllDrives(true)
.execute();
permissionList.getPermissions().forEach(permission -> {
logger.info(permission.getEmailAddress());
});
} catch (IOException e) {
e.printStackTrace();
}
});
pageToken = driveList.getNextPageToken();
}
.setFields("nextPageToken, permissions(id,emailAddress,role)")
可以回傳id,emailAddress,及role
將所有的成員都設定為檢視者
try {
PermissionList permissionList = service.permissions()
.list(drive.getId())
.setFields("nextPageToken, permissions(id,emailAddress)")
.setUseDomainAdminAccess(true)
.setSupportsAllDrives(true)
.execute();
permissionList.getPermissions().forEach(permission -> {
logger.info("設定唯讀:" + permission.getEmailAddress());
try {
Permission readPermission = new Permission();
readPermission.setRole("reader");
service.permissions()
.update(drive.getId(), permission.getId(), readPermission)
.setUseDomainAdminAccess(true)
.setSupportsAllDrives(true)
.execute();
Thread.sleep(35); //避免密集request google api
} catch (Exception e) {
logger.info(e.getMessage());
}
});
} catch (IOException e) {
e.printStackTrace();
}
如果成員已是reader, 送request 進去會出現底下誤誤訊息, 查了google似乎是bug
{
"code": 403,
"errors": [
{
"domain": "global",
"message": "The authenticated user does not have the required access to update the permission.",
"reason": "cannotUpdatePermission"
}
],
"message": "The authenticated user does not have the required access to update the permission."
}
所以就catch exception, 但是不管它, 繼續執行即可
移除permission
PermissionList permissionList = service.permissions()
.list(drive.getId())
.setFields("nextPageToken, permissions(id,emailAddress,role)")
.setUseDomainAdminAccess(true)
.setSupportsAllDrives(true)
.execute();
permissionList.getPermissions().forEach(permission -> {
if (permission.getEmailAddress().matches("igogo@st.tc.edu.tw")) {
try {
service.permissions()
.delete(drive.getId(),permission.getId())
.setUseDomainAdminAccess(true)
.setSupportsAllDrives(true)
.execute();
} catch (IOException e) {
throw new RuntimeException(e);
}
}
});
刪除檔案
無法直接刪除drive, 如果有檔案會出現"This resource cannot be deleted because it has children“
所以要先刪光資料夾底下的檔案
String fileNextPageToken = "";
while (fileNextPageToken != null) {
try {
FileList fileList = service.files().list()
.setDriveId(drive.getId())
.setPageSize(1000)
.setIncludeItemsFromAllDrives(true)
.setSupportsAllDrives(true)
.setCorpora("drive")
.execute();
logger.info(drive.getName() + "," + fileList.getFiles().size());
if (fileList.getFiles().size() == 0) {
//刪資料夾
logger.info("delete drive: " + drive.getName());
deleteDrive(drive.getId());
Thread.sleep(35);
} else {
fileList.getFiles().forEach(file -> {
try {
logger.info("delete file: " + drive.getName() + "," + file.getName());
service.files()
.delete(file.getId())
.setSupportsAllDrives(true)
.execute();
Thread.sleep(35);
} catch (Exception e) {
logger.info(e.getMessage());
}
});
}
fileNextPageToken = fileList.getNextPageToken();
} catch (Exception e) {
logger.info(e.getMessage());
}
}
});
pageToken = driveList.getNextPageToken();
END
